TL;DR: A 2026 scoping review in Sleep Science linked seasonal timing, daylight exposure, daylight saving time (DST), sleep-wake rhythm disruption, and driver drowsiness to traffic-crash risk, but found that few studies directly integrate seasonality with chronobiology in one model. Key Findings 1,758 records screened: The scoping review used PRISMA-ScR methods and screened 1,758 records before …
TL;DR: A 2026 HomePAP secondary analysis in Journal of Clinical Sleep Medicine found that higher PAP mask leak predicted lower obstructive sleep apnea treatment adherence, but a new Real Leak measure, unintentional leak after subtracting expected mask leak, did not outperform conventional Average Leak. Key Findings HomePAP sample size: PAP data were available for 139 …
TL;DR: A 2026 qualitative analysis in PLOS One used 505 ME/CFS memorial entries to map how systemic neglect, clinical dismissal, social isolation, and personal burden appeared in accounts of illness and death. Key Findings 505 memorial entries: The analysis used the National CFIDS Foundation memorial list, downloaded in October 2024. 4 theme layers: Themes were …
TL;DR: A 2026 meta-analysis in Sleep and Breathing found that GLP-1 drugs, metabolic hormone medications involved in glucose, appetite, and weight regulation, were linked to fewer obstructive sleep apnea breathing events in adults with obesity. Key Findings Sleep apnea events fell: GLP-1 treatment reduced apnea-hypopnea index (AHI), a count of breathing interruptions per hour of …
TL;DR: A 2026 cross-sectional study in Nature and Science of Sleep linked 9 hours or less of nighttime sleep with higher parent-rated anxiety scores in 1,589 preschool children in China, but the design can show association rather than prove that shorter sleep caused the symptoms. Key Findings 1,589 preschoolers: Researchers analyzed parent questionnaires from two …
TL;DR: A 2026 eNeuro study of 163 people ages 3-25 found that sleep history and age shaped waking electroencephalography (EEG) oscillations, while children with ADHD showed distinct sleep-wake EEG patterns. Key Findings Sleep and development interact to shape wake EEG oscillations: The amount of recent sleep or wakefulness produces age-dependent effects on EEG oscillation amplitude …
TL;DR: A 2026 preprint on medRxiv using the Harvard Biomarkers Study found that 43% of Parkinson’s disease patients had depression, anxiety, sleep apnea, or restless legs syndrome, compared with 21% of controls. Key Findings 1,224-person cohort: Researchers analyzed 933 Parkinson’s disease cases and 291 controls in the Harvard Biomarkers Study. 43% mood-sleep burden: At least …
TL;DR: A 2026 study in Cell Reports used electroencephalography (EEG), a brain-wave recording method, in 92 nappers to identify four mental states across wakefulness, sleep onset, and light sleep, including a bizarre dream-like state with reduced frontal-occipital connectivity. Key Findings Four distinct mental states emerged from the data, not the expected two: A clustering algorithm …
TL;DR: A 2026 study in Communications Psychology analyzed 1,687 dream reports and 1,679 waking reports, finding that dreams were more visual, spatial, social, bizarre, and emotionally negative than waking experiences. Key Findings 3,366 reports analyzed: the main dataset included 1,687 dream reports and 1,679 waking reports from 207 adults collected between 2020 and 2024. Dreams …
TL;DR: A 2026 study in NEJM Evidence found that solriamfetol added 9.4 minutes of objective wakefulness in early-morning shift work disorder after 4 weeks, without a higher overall adverse-event rate than placebo. Key Findings 78 early-morning workers: Participants had excessive sleepiness linked to shifts starting between 3 a.m. and 7 a.m. Randomized double-blind design: The …
