The extent to which sleep is causally related to mental health is unclear. One way to test the causal link is to evaluate the extent to which interventions that improve sleep quality also improve mental health. We conducted a meta-analysis of randomised controlled trials that reported the effects of an intervention that improved sleep on composite mental health, as well as on seven specific mental health difficulties. 65 trials comprising 72 interventions and N  = 8608 participants were included. Improving sleep led to a significant medium-sized effect on composite mental health ( g+  = −0.53), depression ( g+  = −0.63), anxiety ( g+  = −0.51), and rumination ( g+  = −0.49), as well as significant small-to-medium sized effects on stress ( g+  = −0.42), and finally small significant effects on positive psychosis symptoms ( g+  = −0.26). We also found a dose response relationship, in that greater improvements in sleep quality led to greater improvements in mental health. Our findings suggest that sleep is causally related to the experience of mental health difficulties. Future research might consider how interventions that improve sleep could be incorporated into mental health services, as well as the mechanisms of action that explain how sleep exerts an effect on mental health.

Does improving sleep lead to better mental health? A meta-analysis of randomised controlled trials

Problems sleeping are common. A review of several hundred epidemiological studies [ 1 ] concluded that nearly one-third of the general population experience symptoms of insomnia (defined as difficulties falling asleep and/or staying asleep), between 4% and 26% experience excessive sleepiness, and between 2% and 4% experience obstructive sleep apnoea. Additionally, a recent study of over 2000 participants reported that the prevalence of ‘general sleep disturbances’ was 32% [ 2 ] and Chattu et al. concluded on the basis of a large systematic review of the evidence that public and health professionals need to be more aware of the adverse effects of poor sleep [ 3 ]. Mental health problems are also common, with around 17% of adults experiencing mental health difficulties of varying severities [ 4 ], and evidence from large nationally representative studies suggesting that mental health difficulties are on the increase [ 5 ]. Sleep and mental health are, therefore, global public health challenges in their own right, with each having substantive impacts on both individuals and society [ 3 , 6 , 7 ]. However, problems sleeping and mental health difficulties are also intrinsically linked [ 8 , 9 ]. It was previously assumed that mental health difficulties led to problems sleeping [ 10 , 11 ]; however, the reverse may also be true [ 12 ], such that poor sleep contributes to the onset, recurrence, and maintenance of mental health difficulties [ [13]∗ , [14] , [15]∗ , [16] , [17] ]. Therefore, the extent to which there is a causal relation between (poor) sleep and (worse) mental health and the possibility that interventions designed to improve sleep might be able to reduce mental health difficulties warrants investigation.

Evidence on the relationship between sleep and mental health

The association between sleep and mental health is well documented [ 9 , 13 , [18] , [19] , [20] , [21] , [22] , [23]∗ ]. For example, people with insomnia are 10 and 17 times more likely than those without insomnia to experience clinically significant levels of depression and anxiety, respectively [ 24 ]. Furthermore, a meta-analysis of 21 longitudinal studies reported that people with insomnia at baseline had a two-fold risk of developing depression at follow-up compared with people who did not experience insomnia [ 13 ]. Although research most commonly studies the associations between insomnia and depression and anxiety, there is also evidence that problems sleeping are associated with a variety of mental health difficulties. For example, poor sleep has also been associated with post-traumatic stress [ 25 ], eating disorders [ 26 ], and psychosis spectrum experiences such as delusions and hallucinations [ 23 , 27 ]. Studies have also found that specific sleep disorders, such as sleep apnoea [ 28 ], circadian rhythm disruption [ 29 ], restless leg syndrome [ 30 ], excessive daytime sleepiness and narcolepsy [ 31 , 32 ], sleepwalking [ 33 ], and nightmares [ 34 ] are all more prevalent in those experiencing mental health difficulties.

Unfortunately, most research on the association between sleep and mental health is observational in design. While informative, inferring causation from such studies is difficult. For example, cross-sectional designs tell us that variables are associated in some way, but they cannot say whether one variable precedes the other in a causal chain [ 35 ]. Longitudinal designs provide stronger evidence, but are prone to residual confounding [ [36] , [37] , [38] ] and other forms of bias that limit causal inference [ [39] , [40] , [41] , [42] , [43] ]. The best evidence is provided by studies that randomly allocate participants to experimental and control conditions to minimise the effects of potential confounds [ 44 , 45 ]. Therefore, to establish whether sleeping problems are causally associated with mental health difficulties, it is necessary to experimentally manipulate sleep to see whether changes in sleep lead to changes in mental health over time (i.e., the interventionist approach to causation, [ 46 ]).

Many RCTs have examined the effect of interventions designed to improve sleep (typically cognitive behavioural therapy for insomnia, CBTi), on mental health (typically depression and anxiety). There have also been attempts to meta-analyse some of these RCTs and quantify their effects on mental health outcomes [ [47]∗ , [48] , [49] , [50] ]. However, even these meta-analyses do not permit robust conclusions as to the causal impact of sleep on mental health outcomes for several reasons. First, previous reviews have included studies that did not successfully manipulate sleep (i.e., the intervention did not improve sleep relative to controls). It is not possible to conclude whether sleep is causally linked to mental health if the experimental manipulation of sleep is unsuccessful [ 51 ]. Indeed, these studies simply tell us that it can sometimes be difficult to improve sleep in the first place. Second, reviews have tended to examine the effect of interventions targeting sleep on mental health at the first post-intervention time point. This is problematic for two reasons; 1) there is no temporal lag between the measurement of sleep and measurement of mental health (a key tenet of causal inference); and 2) effects are limited to the short-term where they are likely to be strongest. Third, the focus of previous reviews has been limited to depression and anxiety only, and typically limited to CBTi interventions. Therefore, the effect of improving sleep on other mental health outcomes, using different approaches to intervention, is limited. Finally, to date there has been no or limited attempts to investigate variables that influence – or moderate – the impact of interventions that improve sleep on mental health. It is crucial that the impact of such variables is systematically examined to understand whether the effect of improving sleep on mental health differs across populations, settings, and study designs.

The present review: an interventionist approach to causation

The present review sought to address these issues to provide an accurate and robust estimate of the effect of changes in sleep quality (i.e., as a result of an intervention) on changes in mental health. To test this empirically, we identified randomised controlled trials that successfully manipulated sleep in an intervention group relative to controls, and then measured mental health at a later follow-up point. We did not limit the scope of interventions to CBTi, or the measures of mental health to solely depression and/or anxiety. Instead, we included any intervention designed to improve sleep that produced a statistically significant effect on sleep quality relative to controls and examined the effect of that improvement in sleep on any subsequent mental health outcome. To better isolate the effect of improved sleep on mental health, we excluded interventions that included specific elements targeting mental health (e.g., CBT elements for depression). Given the (potentially) high degree of heterogeneity between studies that this approach might create, we examined the effect of different study characteristics and outcomes using moderation analyses. Our primary hypothesis is that interventions that significantly improve sleep will lead to significantly improved mental health at follow-up.

Eligibility criteria

To be included in the present review, studies needed to 1) be a randomized controlled trial that tested an intervention designed to improve sleep; 2) produce a statistically significant effect on sleep quality when compared to a control group or an alternative treatment, 3) report a measure of mental health subsequent to the measure of sleep quality, 4) report sufficient data to compute an effect size representing the impact of the intervention on both sleep quality and mental health, 5) be written in English, or translatable using available resources. In order to reliably and validly assess the independent contribution of changes in sleep on mental health outcomes among adult populations, studies were excluded if 1) the intervention contained elements that specifically target a mental health problem in addition to elements that target sleep; or 2) recruited children and young people (i.e., <18 years of age).

Search strategy

First, we searched MEDLINE (1946 to present), Embase (1974 to present), PsycINFO (1967 to present), and The Cochrane Library (1898 to present) using the Cochrane Highly Sensitive Search Strategy (i.e., HSSS, [ 52 ]) to identify RCTs that included terms relating to sleep quality and/or sleep disorders, and mental health (see Table 1 for a list of the search terms and Supplementary Material 1 for an example search strategy). Second, the reference lists of extant reviews of the relationship between sleep and mental health were searched for any potential articles. Third, a search for any unpublished or ongoing studies was conducted by searching online databases including White Rose Online, The National Research Register, WHO approved clinical trial databases (e.g., ISRCTN), and PROSPERO. Searches were originally conducted in May 2019 and then updated in February 2021.

Data management and study selection

We followed PRISMA guidelines [ 53 ] when selecting studies. The first phase of screening removed duplicate records and records that were clearly ineligible based on the title and/or abstract. The second phase of screening cross-referenced full-text versions of articles against the inclusion criteria, with eligible records included in the present review, and ineligible records excluded along with reasons for exclusion. Records were screened by two members of the review team, and a sub-sample of 10% of each reviewer's records were second checked by the other reviewer, with almost perfect agreement between the reviewers ( kappa  = 1.00 and 0.99).

Data extraction

Data was extracted from included studies using a standardized form and an accompanying manual detailing each variable for extraction. In addition to extracting statistical data to compute effect sizes, data pertaining to source characteristics of included studies (e.g., publication status, year, impact factor), characteristics of the sample (e.g., age, type of mental health problem), the study (e.g., the nature of the comparison group, length of follow-up), and the intervention (e.g., intervention type, mode of delivery) was also extracted.

Outcomes and prioritization

Measuring improvements in sleep.

The concept of ‘improved sleep’ is multifaceted and can mean different things to different people [ [54] , [55] , [56] ]. Consequently, one challenge for the proposed review was to ensure that included studies assessed a similar notion of improved sleep so that they could be meaningfully combined using a single metric. Therefore, we specified that primary studies reported a measure that reflected the overall quality of sleep experienced by participants. The concept of sleep quality can also be subjective [ 54 ]; however, broadly speaking, sleep quality consists of sleep continuity (e.g., sleep onset, sleep maintenance, and number of awakenings) and daytime impact (e.g., the extent to which the person feels refreshed on waking and throughout the day, see [ 54 , 57 ]). We used the following hierarchy to decide which outcome measure(s) to use to estimate an effect size (in descending order of prioritization); 1) self-report measures of global sleep quality (e.g., the Pittsburgh Sleep Quality Index); 2) outcomes specific to a given sleep disorder that assess sleep continuity and impact on daily life (e.g., the Insomnia Severity Index); and 3) individual components of self-reported sleep continuity aggregated to form a single composite effect size (e.g., the average effect of intervention on sleep onset latency (SoL) and wake after sleep onset (WASO)).

Measuring mental health

We examined the effect of improving sleep on 1) composite mental health (which included all mental health outcomes reported across studies, see Table 2 for outcomes), and 2) specific mental health difficulties in isolation (e.g., depression separately from other mental health outcomes). We computed the between-group effect of improving sleep on each mental health outcome reported by the study at the furthest follow-up point available. This strategy provides a stringent test of the effect of improving sleep on mental health outcomes in the sense that any changes need to have been maintained over time. In line with previous reviews [ 58 ], these effect sizes were then averaged to form a ‘composite’ measure of mental health. As with the measures of sleep quality, we prioritized self-report measures of mental health rather than observer-rated measures, as arguably it is the subjective experience of mental health problems that is most important [ 59 ].

Risk of bias

Risk of bias was assessed using the risk of bias assessment criteria developed by the Cochrane Collaboration [ 60 ]. RCTs were classified as being at overall risk of bias according to three of the six domains – 1) allocation concealment, 2) blinding of outcome assessment and 3) completeness of outcome data (attrition). RCTs judged as being at low risk of bias for all three domains were judged at overall low risk of bias. RCTs judged as being at high risk for any of the three domains were judged as overall high risk of bias. RCTs judged as a mix of low and unclear risk on these three domains, or all unclear were judged as unclear with respect to risk of bias.

Estimating effect sizes

Hedges g and the associated standard error were estimated using the means and standard deviations reported by each of the primary studies. Where means and standard deviations were not reported, effect sizes were estimated by converting relevant summary statistics into Hedges g . Where studies reported multiple outcome measures for the same/similar constructs (e.g., several measures of depression), effect sizes were computed for each outcome and then meta-analysed in their own right to form one overall effect.

Meta-analytic approach

All analyses were conducted in R [ 61 ], using the ‘ esc ’ [ 62 ], ‘ meta’ [ 63 ], ‘ metafor’ [ 64 ], ‘ dmetar ’ [ 65 ], and ‘ robvis ’ [ 66 ] packages. The pooled, sample-weighted, average effect size was computed using a random effects model as effect sizes between studies are likely to vary considerably [ 67 ]. Following Cohen's recommendations [ 68 ], g  = 0.20 was taken to represent a ‘small’ effect size, g  = 0.50 a ‘medium’ effect size and g  = 0.80 a ‘large’ effect size. The I 2 statistic was used to assess heterogeneity of effect sizes across the included studies and was interpreted according to the classifications suggested by Higgins et al. [ 69 ], where I 2  = 25% indicates low heterogeneity, I 2  = 50% indicates moderate heterogeneity, and I 2  = 75% indicates high heterogeneity. Publication bias was assessed via visual inspection of a funnel plot and Egger's test [ 70 ]. Additionally, Orwin's formula [ 71 ] was used to determine the fail-safe n . Finally, outliers were defined as any effect size for which the confidence intervals did not overlap with the confidence interval of the pooled effect [ 72 ]. We conducted a sensitivity analysis examining the effect of outliers for each outcome by rerunning the analysis with any outlying effect sizes removed.

Subgroup analyses

Moderation analysis was conducted to identify variables that were associated with the effect of improving sleep on mental health outcomes. A minimum of three studies representing each moderator level category was required in order to conduct moderation analysis. For categorical variables, the analysis was based on a mixed effects model, in that the pooling of effect sizes within each moderator level was based on a random effects model, while the comparison of effect sizes between levels was based on a fixed effects model. The Q statistic was then used to assess whether effect sizes were significantly different between moderator levels. For continuous variables, sample-weighted meta-regression was used to investigate the impact of the moderator on mental health effect sizes.

Of these records, 14,687 (97%) were excluded in the first stage of screening, leaving 452 full-text records to be screened. Of these records, 387 (86%) were cross-referenced against the review eligibility criteria and excluded (see Fig. 1 for a breakdown of reasons and Supplementary Materials 2 for a list of the studies excluded at this stage), leaving 65 records for inclusion in the meta-analysis.

Study characteristics

Table 2 describes key characteristics of the included studies. The 65 studies provided 72 comparisons between an intervention that successfully improved sleep quality vs. a control group.

Participants

A total of N  = 8608 participants took part across the 72 interventions. 38 of the comparisons (53%) included participants with a comorbid physical or mental health problem, while 31 (43%) reported no comorbid health problems, and 3 (4%) reported insufficient detail to make a judgement. Of the 38 comparisons including participants with comorbid health problems, 18 (47%) reported mental health diagnoses, and 20 (53%) had physical health problems.

Outcome measures

The majority of comparisons (61, 85%) reported a measure of depression, but 33 (46%) reported a measure of anxiety, 6 (8%) reported a measure of stress, 5 (7%) reported measures of psychosis spectrum experiences (e.g., total, positive, and negative symptoms), 9 (13%) reported a measure of general mood, 2 (3%) reported post-traumatic stress disorder outcomes, 2 (3%) reported measures of suicidal ideation, 4 (6%) reported rumination outcomes, and 1 (2%) reported a measure of psychological burnout.

Interventions and comparisons

Most interventions were multi-component CBTi (53, 74%), but interventions also involved acupuncture (7, 10%), pharmacological treatments (2, 3%), sleep hygiene alone (2, 3%), sleep restriction alone (2, 3%), Tai Chi (2, 3%), CBT for nightmares (1, 2%), herbal remedies (1, 2%), walking (1, 2%), and yoga (1, 2%). Interventions were most often compared against an active control group (34, 47%), but were also compared to waitlist control groups (25, 35%), and groups receiving treatment as usual (13, 18%). On average participants’ mental health was followed-up 20.5 weeks post-intervention (median = 12 weeks post-intervention), with the earliest follow-up being 4-weeks post-intervention, and the furthest follow-up 156-weeks (three years) post intervention.

Manipulation check: did sleep quality improve significantly in the intervention group relative to controls?

Before we examined the effect of improving sleep quality on subsequent mental health, we confirmed that studies included in the review successfully improved sleep quality. The interventions had large and statistically significant effects on sleep quality at the earliest follow-up point reported ( g +  = −1.07, 95% CI = −1.26 to −0.88, p  < 0.001), although heterogeneity between studies was substantial ( I 2  = 79%, Q  = 331.93, p  < 0.001). After twelve outlying effect sizes were removed, the effect of the interventions on sleep quality remained large and statistically significant ( g +  = −0.97, 95% CI = −1.07 to −0.88, p  < 0.001), and heterogeneity was reduced to moderate levels ( I 2  = 43%, Q  = 102.32, p  < 0.001). These findings suggest that the primary studies included in the present review successfully manipulated sleep quality, even after accounting for outliers.

What effect do improvements in sleep quality have on mental health?

Composite mental health

On average, the 72 interventions that successfully improved sleep quality had a statistically significant, medium-sized effect on subsequent composite mental health outcomes, ( g +  = −0.53, 95% CI = −0.68 to −0.38, p  < 0.001); however, there was substantial heterogeneity between the effect sizes, ( I 2  = 76%, Q  = 291.94, p  < 0.001). After re-running the analysis with eleven outlying effect sizes removed, the effect of improving sleep on composite mental health outcomes was small-to-medium sized but still statistically significant, ( g +  = −0.42, 95% CI = −0.49 to −0.34, p  < 0.001) and now relatively homogeneous ( I 2  = 20%, Q  = 75.24, p  = 0.0888). See Fig. 2 for a forest plot.

Interventions that successfully improved sleep quality had a statistically significant, medium-sized effect on depression across 61 comparisons, ( g +  = −0.63, 95% CI = −0.83 to −0.43, p  < 0.001); however, once again, there was substantial heterogeneity, ( I 2  = 81%, Q  = 322.09, p  < 0.001). After re-running the analysis with nine outlying effect sizes removed, the effect of improving sleep on depression remained medium-sized, ( g +  = −0.47, 95% CI = −0.57 to −0.37, p  < 0.001), with moderate heterogeneity, ( I 2  = 32%, Q  = 74.86, p  = 0.0164). See Fig. 3 for a forest plot.

Interventions that successfully improved sleep quality had a statistically significant, small-to-medium sized effect on anxiety across 35 comparisons, ( g +  = −0.50, 95% CI = −0.76 to −0.24, p  < 0.001), with substantial levels of heterogeneity, ( I 2  = 82%, Q  = 187.02, p  < 0.001). After re-running the analysis with four outlying effect sizes removed, the effect improving sleep on anxiety outcomes was small-to-medium sized, but still statistically significant, ( g +  = −0.38, 95% CI = −0.49 to −0.27, p  < 0.001), with lower levels of heterogeneity, ( I 2  = 43%, Q  = 52.49, p  = 0.0067). See Fig. 4 for a forest plot.

Interventions that successfully improved sleep quality had a statistically significant, small-to-medium sized effect on stress ( g +  = −0.42, 95% CI = −0.79 to −0.05, p  = 0.033), across six comparisons. There were moderate levels of heterogeneity ( I 2  = 55%, Q  = 11.05, p  = 0.05), but there were no outlying effect sizes. See Fig. 5 for a forest plot.

Psychosis spectrum experiences

Interventions that successfully improved sleep quality had a small effect on total symptoms as indicated by the PANSS ( g +  = −0.17, 95% CI = −0.53 to 0.19, p  = 0.18) across three comparisons, with zero heterogeneity ( I 2  = 0%, Q  = 0.41, p  = 0.813). Interventions that successfully improved sleep quality had a small effect on positive symptoms ( g +  = −0.26, 95% CI = −0.43 to −0.08, p  = 0.014) across five comparisons, with zero heterogeneity ( I 2  = 0%, Q  = 1.71, p  = 0.788). Finally, interventions that successfully improved sleep quality had a small effect on negative symptoms ( g +  = −0.28, 95% CI = −3.22 to 2.65, p  = 0.436) across k  = 2 comparisons, with zero heterogeneity ( I 2  = 0%, Q  = 1, p  = 0.318). See Fig. 6 for a forest plot.

Suicidal ideation

Interventions that successfully improved sleep quality had a small, adverse effect on suicidal ideation ( g +  = 0.10, 95% CI = −3.74 to 3.94, p  = 0.804) across two comparisons. There were low levels of heterogeneity ( I 2  = 20%, Q  = 1.25, p  = 0.263) and no outlying effect sizes. See Fig. 5 for a forest plot.

Post-traumatic stress disorder (PTSD)

Interventions that successfully improved sleep quality had a medium-to-large effect on PTSD ( g +  = −0.72, 95% CI = −2.90 to 1.46, p  = 0.149) across two comparisons, with zero heterogeneity ( I 2  = 0%, Q  = 0.59, p  = 0.442). See Fig. 5 for a forest plot.

Interventions that successfully improved sleep quality had a statistically significant, medium sized effect on rumination ( g +  = −0.49, 95% CI = −0.93 to −0.04, p  = 0.041) across four comparisons, with moderate heterogeneity ( I 2  = 36%, Q  = 4.65, p  = 0.1991). See Fig. 5 for a forest plot.

Only one study reported the effect of improving sleep on burnout finding almost zero effect ( g  = −0.03, CI = −0.58 to 0.52, p  = 0.917).

Moderators of the effect of improving sleep quality on composite mental health outcomes

Table 4 presents the findings of analyses evaluating categorical moderators of the effect of improving sleep quality on composite mental health outcomes and Table 5 presents analyses evaluating continuous moderators using meta-regression. Studies that found significant effects of the intervention on sleep quality reported larger effects on subsequent composite mental health, ( g  = −0.53, 95% CI = −0.68 to −0.38, p  < 0.001), than studies that did not find a significant effect of the intervention on sleep quality, ( g  = −0.12, 95% CI = −0.24 to 0.01, p  = 0.0522), a difference that was statistically significant, ( Q  = 17.59, p  < 0.001). This finding strengthens the notion that improvements in sleep are behind improvements in mental health. The effect of improving sleep on mental health was larger in studies with shorter follow-up periods, (i.e., <6 months, g + = −0.60), than in studies with longer follow-ups, (i.e., 6 months, g + = −0.18, Q  = 10.75, p  < 0.01). Furthermore, interventions that were delivered face-to-face by a clinician or therapist were associated with significantly larger effects on mental health, ( g + = −0.63), than those that were self-administered by participants, ( g + = −0.34, Q  = 4.50, p  < 0.05). Finally, there was significant variation in the size of the effect between countries ( Q  = 53.69, p  < 0.001). No other statistically significant categorical moderator effects were found. Regarding continuous moderators, meta-regression revealed a statistically significant dose–response effect for the association between the effect of interventions on sleep quality and the effect on subsequent mental health outcomes ( B  = 0.77, 95% CI = 0.52 to 1.02, p  < 0.001), suggesting that greater improvements in sleep led to greater improvements in mental health. No other continuous variables significantly moderated the effect of improving sleep on mental health.

Post-hoc moderation analysis

Is the smaller effect of improving sleep on mental health at longer follow-ups associated with smaller effects on sleep quality.

We conducted further (unplanned) post-hoc analysis to investigate whether the smaller effect of improving sleep on mental health at longer follow-ups was accompanied by a reduction in the improvements to sleep quality. Studies reporting the effect of the intervention at shorter follow-ups reported larger improvements in sleep quality, ( g  = −1.03, 95% CI = −1.27 to −0.78, p  < 0.001), than those reporting longer follow-ups ( g  = −0.44, 95% CI = −0.62 to −0.27, p  < 0.001), a difference that was statistically significant, ( Q  = 14.38, p  < 0.001). This suggests that the smaller effect of improving sleep on mental health at longer follow-ups might be driven by a smaller effect of the interventions on sleep quality at longer follow-ups.

Can some of the effect of improved mental health be explained by CBTi modules that target processes associated with mental health?

Finally, although the present review excluded interventions that specifically and directly targeted mental health, some CBTi protocols include modules that might target similar processes associated with some mental health difficulties (rumination around sleep, catastrophizing over the effect of poor sleep etc.). Therefore, we compared CBTi interventions with modules that could target processes associated with mental health vs. interventions that did not include these modules (e.g., sleep restriction alone, sleep hygiene alone, herbal tea, and pharmacological intervention). There were no significant differences in the effect of improved sleep quality on mental health between CBTi interventions including modules addressing processes associated with mental health ( g  = −0.44, 95% CI = −0.59 to −0.29, p  < 0.001), relative to those that did not ( g  = −0.48, 95% CI = −0.65 to −0.32, p  < 0.001, Q  = 2.51, p  = 0.285). This finding suggests that it is the beneficial effect of improved sleep quality that confers improvements in mental health rather than the inclusion of modules that target processes associated with mental health commonly seen in CBTi protocols.

Risk of bias assessments

Fig. 7 summarizes the weighted assessment of risk of bias. Individual risk of bias judgements for included studies are presented in Supplementary Material 3 . Ten studies (15%) were judged as having low risk of bias, 29 studies (45%) were judged as high risk of bias, and 26 studies (40%) were judged as unclear. The methodological quality of the included studies was not associated with the effect of improving sleep on composite mental health outcomes, Q  = 0.72, p  = 0.395.

Publication bias

A funnel plot of the effect of improving sleep quality on composite outcomes revealed asymmetry in the effect sizes (Egger's regression = −1.09, 95% CI = −1.91 to −0.28, p  < 0.05, see Fig. 8 ). Duval and Tweedie's [ 74 ] trim and fill procedure was therefore used to address the asymmetry. Ten studies were imputed resulting in a statistically significant, small-to-medium sized adjusted effect of improving sleep on composite mental health outcomes ( g +  = −0.35, 95% CI = −0.55 to −0.16, p  < 0.001). Orwin's failsafe n test suggested that an additional 4101 comparisons producing null effects would be needed to reduce the average effect of improving sleep on composite outcomes to zero. Taken together these results suggest that the effect of improving sleep on composite mental health is robust to possible publication bias.

Fig. 8

The present review used meta-analysis to synthesize the effect of 72 interventions that improved sleep quality relative to a control condition on subsequent mental health. The findings revealed that improving sleep quality had, on average, a medium-sized effect on mental health, including clear evidence that improving sleep reduced depression, anxiety, and stress. A dearth of primary studies of other mental health difficulties (e.g., psychosis spectrum experiences, suicidal ideation, PTSD, rumination, and burnout) mean that it is premature to draw definitive conclusions in these areas. It was also notable that we found a dose–response relationship between improvements in sleep quality and subsequent mental health, such that greater improvements in sleep led to greater improvements in mental health. Although there was some evidence of publication bias, the effects remained robust to correction. Taken together, the findings suggest that improving sleep leads to better mental health, therefore providing strong evidence that sleep plays a causal role in the experience of mental health difficulties.

Sleep as a transdiagnostic treatment target

The present findings support the idea that targeting sleep promotes mental health across a range of populations and experiences. The effect of improving sleep quality on composite mental health was medium-sized and statistically significant, regardless of the presence of physical and/or mental health comorbidities. This finding is particularly important given the healthcare challenges associated with multimorbidity [ 75 ] and mental and physical health problems often co-occur [ [76] , [77] , [78] , [79] ], something that appears to be increasing [ 80 ]. Consequently, it is important that the benefits of improving sleep on mental health occur even in the presence of comorbid health complaints, as was reported in the present research. Improving sleep has also been shown to improve aspects of physical health, including fatigue [ 81 ], chronic pain [ 82 , 83 ], and overall health related quality of life [ 84 ] and could reduce the cost of healthcare. For example, offering a digital CBTi intervention (Sleepio) to primary care patients was associated with an average saving of £70.44 per intervention user [ 85 ], and cost savings following sleep intervention have also been specifically reported in people with comorbid mental health difficulties such as depression [ 86 ].

Another finding to suggest that targeting sleep could promote mental health across a range of populations and experiences, is that we found no difference in the effect of improving sleep quality on mental health between those with clinically defined mental health difficulties and those with non-clinical experiences or between those recruited from clinical vs. community settings, with both groups receiving significant benefits of improved sleep on mental health. This suggests that improving sleep could prove helpful across a range of mental health severities, thus broadening the possible impact of sleep interventions within healthcare services. Finally, there is growing evidence that sleep disturbances predict the development of mental health difficulties in the future. For example, shorter and more variable sleep has been shown to be longitudinally associated with more severe hallucinations and delusional ideation in those at high-risk of psychosis [ 87 ]. The present research found that improving sleep has a significant beneficial impact on future mental health in those with non-clinical experiences, raising the possibility that delivering interventions that improve sleep early might limit the risk of developing (or exacerbating) substantive mental health difficulties. Indeed, less severe mild-to-moderate presentations of mental health difficulties can develop over time into more severe mental health diagnoses [ 88 , 89 ], therefore improving sleep might be one tool that can be used in combination with others to limit the risk of transition.

Strengths and limitations

The present review has several strengths. First, it provides a comprehensive and up-to-date search of RCTs examining the effect of improving sleep on a variety of subsequent mental health outcomes. Indeed, with 65 RCTs and N  = 8608 participants, the present review is one of the largest studies of the effect of improving sleep on mental health to date. Second, the review was specifically designed to test the causal association between sleep and mental health (i.e., RCTs only, successful sleep improvement required, temporal lag between measures etc.). To our knowledge, the review is the first to adopt this approach in the field of sleep and mental health, although the general approach has been used in other fields [ 90 ]. Finally, we provide an analysis of possible moderators of the effect of improving sleep on mental health, identifying several key moderators of the effect.

However, there are limitations that must be considered when interpreting the findings. First, relatively few studies examined the effect of improving sleep over the long term. Those that did report longer follow-ups generally found smaller effects (although still statistically significant), most likely due to the diminishing effects of interventions on sleep quality over time [ 91 ]. Consequently, it is important that interventions targeting sleep quality as a route to improving mental health seek to maintain their beneficial effects. Second, there were few primary studies for some of the outcomes included in this review. Consequently, in lieu of more studies reporting these outcomes, the inferences that we can make for mental health outcomes other than depression and anxiety are more limited. Third, although the intention of the present review was to include a broad range of sleep disturbances, most of the analyses are based on CBT interventions for insomnia. This might be due to the relationship between insomnia and mental health being the one that is historically most studied. However, it may be that our focus on sleep quality precluded some studies that do not focus on insomnia from inclusion. For example, different sleep disorders have different conceptualisations of improvement that might not include sleep quality. For example, the timing of sleep is particularly important in circadian rhythm disorders and daytime sleepiness is a key outcome in sleep apnoea research. Future research might consider examining the effect of improving specific sleep disorders on mental health by conceptualising improvements using sleep disorder specific outcomes.

Future directions

The present review highlighted several areas for future research in terms of both research and theory, and the implementation of findings in practice. First, given that mental health was measured on average around 20.5 weeks post-intervention in the primary studies, and that the effect of improving sleep on mental health significantly reduced over time, future research should examine the effect of improving sleep on mental health over the longer term. Second, although not uncommon, the majority of RCTs included in the present review were at high risk, or unclear risk or bias. Consequently, in addition to studying the effect of improving sleep over the longer term, on a range of mental health difficulties beyond depression and anxiety, we need more research at lower risk of methodological bias.

Finally, although the present research provides evidence for a causal association between sleep and mental health, it is less clear how sleep affects mental health. One potential mechanism is whether and how people regulate their emotions (e.g., in response to negative events). Indeed, evidence suggests that poor sleep can amplify the adverse effect of negative life events [ 92 , 93 ], dull the beneficial impact of positive events [ 94 ], and is associated with more frequent use of emotion regulation strategies that might be detrimental to good mental health [ 95 ]. By extension, although we are unaware of RCTs testing the effect of improved sleep on emotion regulation, changes in sleep are prospectively associated with changes in aspects of emotion regulation [ 96 , 97 ], while experimentally induced sleep deprivation is adversely linked to poorer emotion regulation [ 96 , 97 ]. Contemporary perspectives on emotion regulation (e.g., the action control perspective), draw on research on how people regulate their behaviour, to propose that regulating emotions involves three tasks, 1) identifying the need to regulate, 2) deciding whether and how to regulate, and 3) enacting a regulation strategy [ 98 ]. We propose that poor sleep quality has the potential to adversely affect anyone (or all) of the three tasks involved in effectively regulating emotions, which might go some way toward explaining the relationship between poor sleep and mental health. Therefore, we would recommend that future research includes measures of aspects of emotion regulation (e.g., the Difficulties in Emotion Regulation Scale, [ 99 ]) within experimental and longitudinal designs to elucidate possible mechanisms by which improvements in sleep benefit mental health.

In terms of practice and implementation, evidence on the effect of sleep on mental health also supports calls for routine screening and treatment of problems with sleep. Both the Royal Society for Public Health (RSPH) and the Mental Health Foundation (MHF) recommend that primary health care training should include awareness of, and skills in assessing, sleep problems [ 100 , 101 ]. Despite this and a growing body of evidence, there has been little progress to date [ 102 ]. This may reflect under-appreciation of the importance of sleep [ 103 ] and lack of training and skills in assessing and managing sleep problems [ [104] , [105] , [106] , [107] , [108] ], as well as limited time and resources [ 103 , 109 ]. Therefore, a profitable next step might be to explore barriers and facilitators to assessing sleep and delivering effective interventions in specific care settings, from both the patient and clinician perspective. Indeed, the present review also highlighted a dearth of trials that tested the effect of improving sleep on mental health outcomes in ‘real world’ settings (e.g., within existing clinical and community health services). Although some researchers are taking important steps in this area [ [110] , [111] , [112] ], there is a clear need for more trials of interventions in clinical services so that the effectiveness and implementation of such interventions in routine care can be better understood.

Conclusions

Taken together, the present research supports the view that sleep is causally related to the experience of mental health difficulties, and therefore that sleep represents a viable treatment target that can confer significant benefits to mental health, as it has been found to do for physical health. We found that improving sleep was associated with better mental health regardless of the severity of mental health difficulty (i.e., clinical vs. non-clinical) or the presence of comorbid health conditions. Poor sleep is almost ubiquitous within mental health services [ 102 , 108 , 113 , 114 ], is causally related to the experience of mental health difficulties, and represents a potential treatment target [ 105 , 115 , 116 ]. Consequently, equipping health professionals with greater knowledge and resources to support sleep is an essential next step. Future research should consider how interventions that improve sleep could be better incorporated into routine mental health care, as well as the possible mechanisms of action that might explain how sleep exerts its effects on mental health.

Research agenda

To fully harness the effect of improved sleep on mental health, it is important that future research:

  • 1. Explores the barriers and possible solutions to incorporating interventions that improve sleep into mental health care services.
  • 2. Tests the effect of improving sleep on mental health outcomes beyond depression and anxiety, and over the long term, using designs at low risk of methodological bias.
  • 3. Investigates the possible mechanisms of action that might explain how sleep exerts its effects on the experience of mental health difficulties.

Practice points

  • • Sleep is causally related to the experience of mental health difficulties and represents a viable transdiagnostic treatment target for those experiencing mental health difficulties.
  • • Improving sleep has beneficial effects on the experience of mental health difficulties, regardless of the severity of those difficulties, or the presence of comorbid health conditions.
  • • Healthcare professionals aiming to improve mental health (particularly depression, anxiety, and stress) should consider interventions designed to improve sleep, particularly cognitive behavioral therapy for insomnia where the evidence base is strongest.

Collection  28 April 2022

The psychology of sleep

Sufficient and good-quality sleep not only plays an integral role in our physical but also in our mental wellbeing. This Collection focuses on the role of sleep in aspects of human Psychology such as attention, emotion regulation, executive control, memory and learning. In addition, insufficient or low-quality sleep can be a trigger, a side effect, or even as a result of poor mental health.

This Collection welcomes papers exploring the reciprocal relationship between sleep and mental health, as well as work examining the potential benefits of psychological interventions in treating sleep disorders. Purely behavioural and cognitive research as well as research using methods such as neuroimaging or brain stimulation will be considered for inclusion in the Collection.

The Impact of Sleep on Learning and Memory

By Kelly Cappello, B.A.

For many students, staying awake all night to study is common practice. According to Medical News Today , around 20 percent of students pull all-nighters at least once a month, and about 35 percent stay up past three in the morning once or more weekly.

That being said, staying up all night to study is one of the worst things students can do for their grades. In October of 2019, two MIT professors found a correlation between sleep and test scores : The less students slept during the semester, the worse their scores.

So, why is it that sleep is so important for test scores? While the answer seems simple, that students simply perform better when they’re not mentally or physically tired, the truth may be far more complicated and interesting.

In the last 20 years, scientists have found that sleep impacts more than just students’ ability to perform well; it improves their ability to learn, memorize, retain, recall, and use their new knowledge to solve problems creatively. All of which contribute to better test scores.

Let’s take a look at some of the most interesting research regarding the impact of sleep on learning and memory.

How does sleep improve the ability to learn?

When learning facts and information, most of what we learn is temporarily stored in a region of the brain called the hippocampus. Some scientists hypothesize that , like most storage centers, the hippocampus has limited storage capacity. This means, if the hippocampus is full, and we try to learn more information, we won’t be able to.

Fortunately, many scientists also hypothesize that sleep, particularly Stages 2 and 3 sleep, plays a role in replenishing our ability to learn. In one study, a group of 44 participants underwent two rigorous sessions of learning, once at noon and again at 6:00 PM. Half of the group was allowed to nap between sessions, while the other half took part in standard activities. The researchers found that the group that napped between learning sessions learned just as easily at 6:00 PM as they did at noon. The group that didn’t nap, however, experienced a significant decrease in learning ability [1].

How does sleep improve the ability to recall information?

Humans have known about the benefits of sleep for memory recall for thousands of years. In fact, the first record of this revelation is from the first century AD. Rhetorician Quintilian stated, “It is a curious fact, of which the reason is not obvious, that the interval of a single night will greatly increase the strength of the memory.”

In the last century, scientists have tested this theory many times, often finding that sleep improves memory retention and recall by between 20 and 40 percent. Recent research has led scientists to hypothesize that Stage 3 (deep non-Rapid Eye Movement sleep, or Slow Wave Sleep) may be especially important for the improvement of memory retention and recall [2].

How does sleep improve long-term memory? 

Scientists hypothesize that sleep also plays a major role in forming long-term memories. According to Matthew Walker, professor of neuroscience and psychology at UC Berkeley, MRI scans indicate that the slow brain waves of stage 3 sleep (deep NREM sleep) “serve as a courier service,” transporting memories from the hippocampus to other more permanent storage sites [3].

How does sleep improve the ability to solve problems creatively?

Many tests are designed to assess critical thinking and creative problem-solving skills. Recent research has led scientists to hypothesize that sleep, particularly REM sleep, plays a role in strengthening these skills. In one study, scientists tested the effect of REM sleep on the ability to solve anagram puzzles (word scrambles like “EOUSM” for “MOUSE”), an ability that requires strong creative thinking and problem-solving skills.

In the study, participants solved a couple of anagram puzzles before going to sleep in a sleep laboratory with electrodes placed on their heads. The subjects were woken up four times during the night to solve anagram puzzles, twice during NREM sleep and twice during REM sleep.

The researchers found that when participants were woken up during REM sleep, they could solve 15 to 35 percent more puzzles than they could when woken up from NREM sleep. They also performed 15 to 35 percent better than they did in the middle of the day [4]. It seems that REM sleep may play a major role in improving the ability to solve complex problems.

So, what’s the point?

Sleep research from the last 20 years indicates that sleep does more than simply give students the energy they need to study and perform well on tests. Sleep actually helps students learn, memorize, retain, recall, and use their new knowledge to come up with creative and innovative solutions.

It’s no surprise that the MIT study previously mentioned revealed no improvement in scores for those who only prioritized their sleep the night before a big test. In fact, the MIT researchers concluded that if students want to see an improvement in their test scores, they have to prioritize their sleep during the entire learning process. Staying up late to study just doesn’t pay off.

Understanding the Connection Between Sleep and Anxiety

New research helps explain the crucial linkages between sleep and mental health..

Research findings suggesting that sleep loss and anxiety are closely linked were among those presented at Neuroscience 2018 , the annual conference of the Society for Neuroscience , held in San Diego, California. The news isn’t all dire, however—this year’s event offered some science-based encouragement along with causes for concern.

Neuroscience continues focusing on the mysteries of sleep (and yes, it’s still plenty mysterious, despite its media ubiquity)—not only the perils of failing to get enough, but also the list of vital roles it plays in our brains.

Research discussed at this year’s event touched on a range of findings, from sleep's roles in memory consolidation to garbage removal in brain tissue. We’re learning via more studies each year that sleep, including well-placed naps, facilitates the brain’s consolidation of information—moving memory freight from short-term to long-term storage, and sharpening its accessibility for when we need it. Without sleep, memory simply doesn’t happen.

We’ve also learned that sleep provides the brain with an invaluable period of transporting toxins out of neural tissue through a complex garbage-removal system. Operating separately from the body's lymphatic system, the brain’s trash-disposal apparatus seems dependent on sleep to function properly. Links between neurodegenerative diseases, like Alzheimer’s and the accumulation of toxins in brain tissue, are exceptionally strong, and sleep loss is a likely culprit.

A panel session at this year’s event called “Threats of Sleep Deprivation” highlighted new findings on the connection between sleep loss and anxiety.

“Sleep deprivation isn’t what we usually think it is,” said session moderator Clifford Saper, MD, Ph.D., of Harvard Medical School. It’s usually not “staying up 40 hours all at once,” but rather gradually losing sleep over time.

Saper noted that most sleep deprivation is more specifically REM (rapid eye movement) deprivation, referring to the period of sleep during which the body becomes more relaxed, while the brain becomes more active. During the normal cycle of sleep, people spend about 20 percent of the time in REM, but disrupted sleep derails the cycle, with consequences for memory, the nervous and immune systems, and more.

Research presented during the panel found that brain activity after periods of sleep deprivation mirrors brain activity indicative of anxiety disorders. The amygdala—the seat of the brain’s fight or flight response—is particularly “aroused” when we haven’t slept enough.

One study found that the brains of participants who’d experienced even brief periods of sleep deprivation showed greater activity in a complex of “ emotion -generating regions of the brain” and reduced activity in “emotion-regulating regions.”

These findings are linked to why people with anxiety disorders often report an explosion of anxiety first thing in the morning. Poor sleep seems to put the brain on-guard by triggering spikes in stress hormones like cortisol, producing an early a.m. “anxiety bloom” even before the day begins.

The panel also addressed the "vicious cycle of anxiety and sleep loss"—while sleep loss is often a precursor for anxiety disorders, anxiety also leads to sleep loss. The conditions fuel each other, with compounding effects.

Thankfully, science is also serving up some good news with practical applications. Because the link between anxiety and sleep is so strong, researchers reported that “sleep therapy ” could be an effective method of treating anxiety disorders. Finding ways to improve an anxiety patient’s sleep could be one of the most overlooked and accessible treatment opportunities.

“The results [of the research] suggest that sleep therapy could reduce anxiety in non-clinical populations as well as people suffering from panic attacks, generalized anxiety disorder, post- traumatic stress disorder, and other conditions,” said panelist and lead study author Eti Ben-Simon, Ph.D., of the Center for Human Sleep Science at the University of California, Berkeley.

And the really good news is that many of the negative effects of sleep loss appear reversible after just one night of peaceful sleep.

“For healthy people, research shows that one night of recovery sleep brings systems back online and brings anxiety levels back to normal,” added Dr. Ben-Simon.

Which may help explain why previous research has found that catching up on sleep during the weekend turns out to be effective—a couple nights of solid sleep can balance many of the negatives from drudging through stressful weekday nights. It’s not an ideal solution (the gold standard is consistently sleeping well), but it's certainly better than not recovering at all.

The takeaway:

Even if you’re struggling to sleep well, make sure to at least get a recovery night or two during the week to tune down the emotion-generating parts of the brain and bring emotion-regulation back online. That’s just one among many benefits of getting a good night’s sleep, but an especially crucial one when it comes to managing anxiety.

Research discussed in this article was presented at Neuroscience 2018 , the annual conference of the Society for Neuroscience. Research presented at the conference is generally considered preliminary prior to being published in peer-reviewed journals.

Getting a good night’s sleep: How psychologists help with insomnia

Psychologists provide tips that can be helpful in changing unhealthy habits and improving your sleep.

  • Psychotherapy

Sleeping

How many times did you hit the snooze button this morning? We all crave sleep, but too many nights we fall short of the seven or eight hours we need to thrive. An estimated 50 to 70 million Americans suffer from a chronic sleep disorder, according to the Institute of Medicine.

In today’s overscheduled society, sleep may feel like a luxury when, in fact it’s a necessity. Sleep is vital to our health, safety and overall well-being. Sleep recharges the brain, allowing it to learn and make memories. Insufficient sleep has been linked to car crashes, poor work performance and problems with mood and relationships. Sleep deprivation also raises the risk of high blood pressure, heart disease, diabetes, obesity, depression, and stroke.

Seeing a psychologist about sleep disorders

In many cases, people experience insomnia because they develop a pattern of behavior that interferes with good sleep habits. Sleeping difficulties are often connected to underlying problems such as stress, depression or anxiety.

It is a good idea to consult with a physician or another medical professional to learn if medical issues may be contributing to your sleep difficulties and treat related medical problems. Seeing a psychologist may also help you address sleep problems. Psychologists can help people change their behaviors and manage the thoughts, feelings and emotions that can interfere with a healthy night’s sleep. Licensed psychologists have the professional training and skills to treat individuals suffering from depression and anxiety, which have been linked to sleep problems like insomnia.

In working with a psychologist, you can expect to talk about your overall physical and emotional health, and your health beliefs and behaviors. A psychologist will help you identify any underlying stressors and behaviors that may be interfering with sleep.

A psychologist may ask you to keep a sleep diary with information about your routines and behaviors. This can help the psychologist identify patterns of behavior that might be interfering with sleep. For instance, if you have a habit of exercising at night or watching television in bed, your psychologist can help you take a look at how your routines impair sleep, and help you find alternatives. The psychologist may also teach you relaxation techniques to help you learn to quiet your mind and unwind before bed.

Depression and sleep

Depression is one of the most common mental illnesses. More than 16% of Americans experience major depressive disorder during their lifetime, according to the National Institute of Mental Health. And depression and sleep problems often go hand in hand.

Many people with depression experience hypersomnia, a condition in which they sleep more than normal. On the other end of the sleep spectrum, insomnia is also common among people with depression. In fact, research suggests that people with insomnia are 10 times as likely to suffer from clinical depression.

Some people develop sleep problems first, and then go on to experience depression. In others, depression occurs before signs of sleep disorders. In either case, sleep difficulty is just one of many reasons to seek treatment for depression.

Depressed people typically feel hopeless and guilty. They often lose interest in routine activities and withdraw from family and friends. They may have thoughts of suicide. Treatment can address both depression and the sleep problems that go along with it.

Understanding insomnia

Insomnia is a common sleep disorder that occurs in 30 million Americans, according to the Institute of Medicine. A person with insomnia has trouble falling or staying asleep. When sleepless nights persist for longer than a month, the problem is considered chronic. Often, people with chronic insomnia see the problem come and go, experiencing several days of good sleep followed by a stretch of poor sleep.

Studies show that people with insomnia who learned to recognize and change stressful thoughts slept better than those who took sleeping pills to treat their insomnia.

Whatever the cause, you’re more likely to rest if you adopt healthy sleep behaviors. Much like diet and exercise, sleep is a basic building block to health.

Steps to better sleep

Consider the following steps that can be helpful in changing unhealthy habits and improving your sleep.

  • Create a relaxing sleep environment. Keep your bedroom dark, cool, and as quiet as possible and keep electronics such as a computer, TV, and phones out of the bedroom. Exposure to stimulating objects and lights from computer and TV screens can affect levels of melatonin, a hormone that regulates your body’s internal clock.
  • Don’t discuss or deal with stressful or anxiety-inducing situations right before bedtime . Just as exercise can increase energy levels and body temperature, discussing difficult topics will increase tension and may provoke a racing heartbeat. Protect the quality of your sleep by dealing with any stressful topics long before bedtime.
  • Set a sleep schedule. Maintain a regular sleep routine. Go to bed and get up at the same times each day, even on the weekends. Don’t go to bed too early. If you hit the sack before you’re sleepy, you may lie in bed awake and start to feel anxious. That will only make it more difficult to drift off.
  • Limit naps. Late afternoon naps can interfere with nighttime slumber.
  • Maintain a regular exercise routine. Research shows that exercise increases total sleep time, particularly the slow-wave sleep that’s important for body repair and maintenance. However, don’t exercise too late in the day. Working out close to bedtime can boost energy levels and body temperature, making it harder to fall asleep.
  • Avoid late night meals and alcohol consumption. Skip heavy meals before bed, and limit alcohol. Even if a cocktail seems to help you fall asleep, it can interfere with sleep quality and disrupt sleep later in the night.
  • Curb nicotine and caffeine use . These stimulants can make it harder to fall asleep and stay asleep, especially if consumed late in the day.
  • Schedule down time before bed. Setting aside time to unwind and quiet your mind will help you get into a sleepy state of mind. Meditating, breathing exercises, taking a bath and listening to relaxing music are great ways to calm down at night.
  • Don’t check the clock. Tallying how much sleep you’re losing can create anxiety and make it harder to fall asleep.
  • Take notes. If you can’t stop the stream of thoughts, get up and write them down. Tell yourself you can check the list in the morning, so there’s no need to keep worrying tonight.

Characteristics of a Good AP Research Paper

Strong AP research topics stand out due to several key features that ensure their impact. Here's what to keep in mind:

  • Timeless Relevance: Select a topic that maintains its significance over time. Avoid subjects likely to become outdated quickly. Instead, focus on issues with long-term importance that can be referenced by future researchers.
  • Supported by Credible Sources: Your research must be backed by reliable sources. For example, research supported by academic databases like JSTOR or publications from trusted institutions such as the National Institutes of Health (NIH) adds credibility.
  • Clear and Insightful Research Questions: Good questions help define the scope of your paper and shape your analysis, ensuring that your research is both relevant and insightful. For example, if your topic involves the impact of digital marketing, questions inspired by case studies from companies like Google or Adobe can provide a structured framework for your analysis.
  • Specific Focus: Narrow your topic to address specific issues, avoiding overly broad subjects. For instance, if researching the effects of climate change, focus on a particular aspect such as its impact on urban agriculture.
  • Logical Structure and Clarity: Ensure your paper has a clear introduction, body, and conclusion. Each section should flow logically, with well-organized arguments and evidence. A clear structure helps readers follow your argument and enhances the overall readability of your paper.

By considering these pointers suggested by EssayPro, your paper will make a valuable contribution to your field of study. It'll also be easy for you to draw on the best practices and examples from leading research institutions and industry experts.

Tips for Choosing an AP Research Topic

Here are some useful tips to help you choose standout AP research topic ideas:

  • Examine Current Trends: Look at recent news, technological advances, or social movements for inspiration. Topics like the effects of remote work on productivity or the rise of sustainable fashion can be both timely and impactful.
  • Reflect on Your Passions: Whether it's a hobby, a cause, or a field you're curious about, your enthusiasm will make the research process more enjoyable and your writing more compelling.
  • Seek Out Gaps in Existing Research: Identify areas where there's a lack of information or where current research is outdated. For example, if you notice few studies on the psychological effects of digital detoxes, that might be a unique angle worth exploring. EssayPro can also help you find existing research and identify gaps that need further investigation.
  • Consult with Experts: Talk to teachers, mentors, or professionals in fields you're interested in. Their insights can help you identify important topics. You might also find useful examples and advice from Essaypro's expert writers.
  • Consider Practical Applications: Choose a topic with real-world applications or implications. Researching the impact of new educational technologies on classroom dynamics, for example, can provide valuable insights and practical solutions.
  • Look at Your Local Community: Local issues or events can offer unique and relevant topics. Investigate how local policies affect community health or how a local environmental issue is being addressed. These topics can provide fresh perspectives and direct relevance.
  • Use Personal Experience: Leverage your own experiences or observations. If you've noticed a trend or issue in your daily life, such as the impact of social media on teen behavior, it can provide a unique and personal angle for your research.
