View all →Melatonin reduces sleep onset latency by approximately 7 minutes in adults with primary sleep disorders
A comprehensive meta-analysis of 19 RCTs (1,683 participants) found melatonin reduces sleep latency by ~7 minutes and increases total sleep time by ~8 minutes. Effects are more pronounced in older adults and those with circadian rhythm disruptions.
Low-dose melatonin (0.5mg) effectively shifts circadian rhythm for jet lag, shift work, and delayed sleep phase syndrome
Melatonin is the most potent chronobiotic available. Administered 5 hours before dim-light melatonin onset (DLMO), even low doses (0.5mg) produce a 1-2 hour phase advance. This makes it effective for jet lag, shift work adaptation, and delayed sleep phase syndrome. Timing is more critical than dose.
Glycine reduces sleep latency in human RCTs
Glycine (3g before bed) significantly reduces sleep onset latency and improves subjective sleep quality in healthy adults. Evidence from 3 human RCTs shows consistent effects, with the mechanism involving NMDA receptor modulation and thermoregulation.
Moderate-intensity aerobic exercise (150 min/week) significantly improves sleep quality in adults with chronic insomnia
A 4-week RCT found 150 min/week of moderate aerobic exercise significantly improved PSQI scores and objective sleep measures in adults with chronic insomnia. Exercise is recommended as a first-line behavioral intervention for insomnia.
Glycine improves overall sleep quality and reduces daytime sleepiness
Beyond reducing sleep latency, glycine (3g before bed) improves PSG-measured sleep quality including increased REM sleep and reduced nocturnal awakenings. Daytime sleepiness and fatigue are also significantly reduced the following morning.
Ashwagandha root extract (300mg BID) significantly improves sleep quality and reduces sleep onset latency in adults with insomnia
A well-designed 8-week RCT (n=138) found ashwagandha root extract significantly improved PSQI scores, reduced sleep onset latency, and improved sleep efficiency. Benefits were most pronounced in adults with insomnia and anxiety.

NIV may confer greater short-term clinical benefit in children with severe acute asthma requiring respiratory support
In a systematic review and meta-analysis of pediatric asthma exacerbations, non-invasive ventilation (NIV) showed the greatest improvement in asthma scores compared to oxygen (MD = 1.24, p = 0.07), reaching significance in sensitivity analysis (MD = 2.5, p < 0.001). High-flow nasal cannula (HFNC) showed no significant benefit over oxygen (MD = 0.24, p = 0.58) and was associated with higher failure rates compared to NIV (12.6% vs. 2.6%, OR = 5.3, p < 0.001).
CPAP therapy improves surrogate, intermediate, and functional cardiovascular outcomes in adults with obstructive sleep apnea, particularly blood pressure, left ventricular function, and sympathetic activity.
This umbrella review of 38 systematic reviews and meta-analyses found that CPAP therapy was associated with significant reductions in systolic blood pressure (MD -4.8 mmHg) and diastolic blood pressure (MD -3.0 mmHg), improvements in left ventricular ejection fraction (MD 3.27) and diastolic function (WMD 0.22), and reduced sympathetic activity (noradrenaline SMD -1.10). However, the certainty of evidence ranged from low to moderate, and no consistent reduction in major adverse cardiovascular events or mortality was demonstrated.
Single-use negative pressure wound therapy (PICO 7) is a safe and feasible alternative to conventional care for chronic lower limb wounds, with favorable trends in wound area reduction but no statistically significant between-group difference.
In a randomized controlled trial of 31 patients with chronic lower limb wounds, the PICO 7 group showed a higher mean percentage reduction in wound size compared to usual care, but the difference was not statistically significant. No infections were recorded in the PICO 7 group, and quality of life and physical activity remained stable in the intervention group while declining in the control group. A significant negative correlation was found between final wound size and hours of sleep, suggesting wound reduction facilitates better rest.
LCR35 supplementation does not significantly improve pruritus or sleep outcomes in maintenance hemodialysis patients
In a 12-week randomized, open-label controlled study of 78 maintenance hemodialysis patients, LCR35 supplementation (three sachets daily) showed descriptive improvements in pruritus (5-D Itch Scale) and selected sleep outcomes (PSQI), but none of the baseline-adjusted between-group differences were statistically significant. For example, the 5-D Itch Scale difference was -1.48 (95% CI, -3.64 to 0.68; p = 0.176) and global PSQI difference was -0.80 (95% CI, -2.09 to 0.50; p = 0.225).
Stellate ganglion block may alleviate postherpetic neuralgia by modulating neurovascular function, inhibiting inflammatory responses, and blocking pain transmission pathways, but evidence-based data on its efficacy and safety remain insufficient.
This protocol describes a systematic review and meta-analysis to evaluate the efficacy and safety of stellate ganglion block (SGB) for postherpetic neuralgia (PHN). The study will search multiple databases up to December 31, 2025, and will use standard meta-analytic methods. The abstract notes that current evidence is insufficient and inconsistent, indicating the need for this review.
Adjunctive mindfulness-based cognitive therapy improves short-term sleep quality in late-life depression
In a randomized controlled trial of 60 older adults with late-life depression, adding MBCT to treatment as usual improved subjective sleep quality (PSQI) at 8 weeks (between-group difference in change: -3.80, 95% CI -6.50 to -1.10) and increased stable sleep duration by 0.94 hours (95% CI 0.17 to 1.71) compared to TAU alone. Reduced functional connectivity between the right nucleus accumbens and left amygdala during meditation relative to rest was associated with greater increases in stable sleep duration (r=0.45, p=0.013).
