Sleep

Cognitive behavioural therapy for insomnia had the strongest economic evidence in this review. Both that therapy and medication were judged likely to offer value compared with inactive controls. Digital therapy was reported to save costs in some comparisons, but the abstract does not show how much or in which settings.

Keep in mind: This abstract-based account cannot identify the countries, evaluation time horizons or uncertainty behind the economic conclusions. No eligible hypersomnia evaluations were found, and evidence for adolescent insomnia was limited.

Among people receiving morning light treatment, season, available daylight, bedtime and adherence did not significantly predict improvement in depression symptoms. Later bedtime showed a suggestive but uncertain pattern. Because this analysis examined differences among treated participants, it does not establish that treatment works equally well across seasons, chronotypes or levels of adherence.

Keep in mind: Adherence was high and closely monitored, limiting what these data can show about lower adherence. The abstract provides no comparison with an untreated group for judging whether symptom improvement was caused by treatment.

In this laboratory setting, eating a meal or snack during the night increased total cortisol output compared with not eating at that time. Consecutive simulated night shifts also altered the hormone's daily pattern. These are short-term hormone findings; the study does not establish that the observed changes caused illness or other clinical harm.

Keep in mind: Participants were healthy non-shift workers completing a brief simulation. The abstract reports cortisol measurements, so it cannot establish long-term health effects or show whether the same pattern occurs in people routinely working nights.

Fixed night work was linked more strongly with several heart and metabolic outcomes, while rotating work showed more consistent associations with cancer outcomes and poorer sleep. The review could not determine which schedule was more harmful overall. These associations do not establish that a shift pattern caused the reported health problems.

Keep in mind: Direct comparisons between shift types were uncommon. The abstract does not identify reference groups for individual pooled estimates, limiting interpretation of apparent differences between schedules.

Physical activity received the highest ranking for improving sleep in this review of autistic children. Melatonin and behavioral interventions also showed favorable results, while parent education and adjunctive therapies showed limited efficacy. However, the abstract does not provide enough detail to treat the ranking as a definitive guide for an individual child.

Keep in mind: The abstract omits treatment durations, confidence intervals for the reported effects, and clear comparator details for each estimate. Substantial variation between studies further limits interpretation of the rankings.

The review found very limited evidence on sleep apnea treatment around transplantation. A heart-transplant study reported improved sleep-related measurements with nasal CPAP. Untreated apnea was associated with earlier graft dysfunction, but adjusted analyses detected no survival benefit from CPAP. Neither result establishes that treatment prevents graft problems or has no effect on survival.

Keep in mind: Only a few studies qualified, and sleep measurements came from a single heart-transplant study. The abstract supplies no effect estimates or confidence intervals for clinical outcomes.

Most included studies used artificial intelligence to identify obstructive sleep apnea or classify its severity, often from overnight physiological signals. Some models reported high diagnostic performance, but results varied with the data and study design. The review found no treatment or monitoring studies, so it does not show that these tools improve children's care or health outcomes.

Keep in mind: Small samples, differing patient populations and a strong focus on sleep apnea limited generalizability. Validation, data diversity and feasibility remained unresolved, preventing the reported performance from establishing readiness for routine use.

The pooled trials favored melatonin for falling asleep sooner, but found no statistically significant improvement in total sleep time or overall eczema severity scores. Improvement on a separate severity measure did not exceed the review's threshold for a clinically meaningful change. The practical importance of these results remains uncertain.

Keep in mind: This abstract-based summary cannot resolve how the eczema severity measures differed. The abstract also omits participant numbers and treatment lengths, limiting interpretation of the pooled results.

Unguided digital cognitive behavioral therapy for insomnia reduced insomnia severity and depressive symptoms across the included trials. The pooled results describe symptom scores after treatment, while substantial variation between studies means the average cannot show how consistent the benefit was across programs or participants, or how long it lasted.

Keep in mind: Results differed substantially across trials, and the abstract does not describe the comparison treatments or follow-up lengths. This abstract-based summary therefore cannot establish durability or which program would work best.

Across the included trials, cognitive behavioral therapy for insomnia improved sleep quality and reduced insomnia severity in menopausal women. Benefits were reported in analyses of both in-person and remote delivery. The abstract does not specify the comparison treatments, so it cannot show how the therapy compares with any particular alternative or usual-care approach.

Keep in mind: The abstract omits control conditions and study-level bias findings. Follow-up lengths varied, and the summary does not isolate how large the benefit remained at the latest assessment.

The review found better sleep-quality questionnaire scores with qigong than with control conditions. Confidence in that pooled result was low, and results differed substantially across trials. A favorable result for one qigong style and a nonsignificant result for another do not establish that the styles differ in effectiveness.

Keep in mind: The review identified substantial variation between trials and risk of bias in some studies. The abstract does not report program durations, making the timeframe and durability of any sleep benefit unclear.

Nighttime noise and rotating night work were associated with altered melatonin timing and less continuous sleep. Studies in night-duty groups reported higher fasting blood sugar, lower insulin sensitivity and less favorable blood fat profiles. These observations informed a model of repeated exposure, but neither the review nor its simulations establish that the exposures cause disease.

Keep in mind: Studies were too diverse for a pooled estimate. Quality assessments informed interpretation without excluding studies. This abstract-based summary cannot quantify the changes, and the authors explicitly caution against causal conclusions.

Creatine improved sleep-quality ratings and was associated with an earlier bedtime in active men. Cognitive test performance and some shuttle-run measures also improved. Sleep duration, efficiency, and time to fall asleep did not differ significantly from placebo, separating the reported improvement in sleep ratings from measured sleep changes.

Keep in mind: The trial involved a small group of active men. Its abstract cannot establish lasting sleep benefits or applicability to other populations.

The pooled estimate suggests that poor sleep quality was common among people with chronic medical or mental illnesses in Ethiopia. Several personal, social and health characteristics were associated with poorer sleep. These associations cannot show that changing a particular factor would improve sleep or establish the direction of the relationships.

Keep in mind: The abstract does not report the number of included studies, sample size, sleep-quality definitions or assessment periods. Differences in measurement cannot be evaluated from this abstract alone.

This abstract-based genetic study found evidence linking short sleep with greater frailty, and greater frailty with short sleep. The other sleep traits examined did not show statistically significant associations with frailty. Although the method was intended to explore causal relationships, the study did not test whether changing sleep habits prevents or reverses frailty.

Keep in mind: Frailty data came from European participants. The abstract does not give sample sizes or fully explain the effect scales, limiting assessment of generalizability and the practical size of the associations.

Among people living with both diabetes and chronic kidney disease, disturbed sleep was linked with poorer kidney function and other unfavorable health measures. Trials also reported improvements in selected outcomes with airway-pressure treatment or melatonin. The abstract does not establish that these treatments prevent kidney failure or cardiovascular events, or that the findings apply to other populations.

Keep in mind: The abstract gives no participant totals, effect sizes, follow-up lengths or treatment-trial comparator details. Its mixture of observational and randomized studies also requires separating associations from evidence about treatment effects.

Vesicles associated with obstructive sleep apnoea showed altered molecular contents and effects on inflammation, blood-vessel cell function and cancer-cell behavior across the included research. These findings help frame possible disease mechanisms. They do not show that measuring vesicles can reliably diagnose sleep apnoea, predict its complications or improve patient care.

Keep in mind: The evidence spans clinical, animal and cell studies. The authors say vesicle characterization and profiling need more consistent methods before their role in the disease can be clarified.

The analysis found expanding research on childhood obstructive sleep apnea, including greater attention to cognition, behavior, and technology-assisted detection. Its central result is a map of the literature: who publishes, who collaborates, and which topics are becoming prominent. It does not directly test whether a diagnostic tool improves accuracy or helps children recover cognitive function.

Keep in mind: Publication and keyword patterns do not establish clinical effectiveness. The abstract's claims about improved diagnosis and cognitive support go beyond the patient outcomes actually reported by this bibliometric analysis.

Poor sleep quality was common in the Ethiopian women included in this review. Depression and stress, low social support, substance use and intimate partner violence were associated with poor sleep quality. These findings describe patterns in the reviewed samples; they do not establish which factor came first or show that addressing any particular factor would improve sleep.

Keep in mind: Study results varied greatly (I² = 99%), so a pooled estimate may not describe every setting. The abstract gives no shared sleep-quality definition or study-level sampling details.

For people with cancer, the abstract leaves substantial uncertainty about acupuncture's effects on insomnia. Symptom scores did not show a clear benefit over sham treatment. Compared with cognitive behavioural therapy for insomnia, acupuncture probably produced worse insomnia and sleep-quality scores, despite longer total sleep time. The comparator changes the interpretation.

Keep in mind: Small studies, risk of bias and imprecise estimates reduced certainty. Participants were mostly women with breast cancer, and outcomes were assessed at treatment completion, limiting conclusions about other cancer populations or lasting effects.

SleepioRx improved insomnia severity more than online sleep hygiene education, with differences sustained at follow-up. Time awake after initially falling asleep also improved. However, time taken to fall asleep did not show a statistically significant benefit under the adjusted threshold, so the trial's sleep outcomes were not uniformly positive.

Keep in mind: The abstract omits raw severity-score changes, the size of diary-recorded sleep improvements and completion figures. These gaps limit interpretation of individual benefit and participants' experience of the program.

In these small trials, wearing blue-light blocking glasses before bedtime did not produce a statistically clear improvement in the time needed to fall asleep, total sleep time, sleep efficiency or waking after sleep onset. The findings leave uncertainty about effects in either direction; they do not prove the glasses have no effect.

Keep in mind: The pooled evidence included few participants, and confidence intervals allowed effects in either direction. The abstract does not report how long participants used the glasses, limiting conclusions about sustained use.

Across the included trials, mind-body therapies improved pooled sleep quality, depression and anxiety scores in women around or after menopause. The therapies covered diverse activities, so the overall finding should not be read as proof that each approach has the same effect or that any particular therapy is best.

Keep in mind: This abstract-based summary is limited by missing questionnaire names, absolute score changes, detailed adverse-event findings and a common follow-up period. These gaps limit judgments about noticeable symptom relief, safety and durability.

The review found that exercise improved sleep quality in older adults and ranked combined aerobic and resistance training highest. It reported clinically meaningful improvements and larger responses among people who started with poorer sleep. However, the abstract does not provide the effect sizes or uncertainty needed to judge how reliably one exercise approach outperformed another.

Keep in mind: The abstract omits sleep assessment scales, effect estimates, confidence intervals, and detailed comparison conditions. Its rankings and estimated dose patterns cannot establish the best program or expected benefit for an individual.
