In a study of 422 young Australians with emerging mood disorders, published Oct. 29, 2026, in the Journal of Biological Rhythms, depressive symptoms peaked in winter and were linked to less physical activity and to a narrow, very regular daily…
A study of 2,000 US adults published Oct. 29, 2026, in Sleep validated Ru-SATED 4.0, a six-question scale that rates sleep regularity, satisfaction, alertness, timing, efficiency and duration. Scores differed clearly between people with and without sleep disorders.
In two phase 3 trials published Oct. 21, 2026, in the New England Journal of Medicine, retatrutide reduced breathing pauses during sleep by up to 34.3 events per hour at 80 weeks in adults with sleep apnea and obesity, vs.…
In a study of 481,857 adults who had overnight sleep studies, published Oct. 15, 2026, in Sleep, periodic leg movements during sleep were linked to depression, insomnia, high blood sugar and anemia, and may be undercounted in people with sleep…
A study of 4,162 US adults, published Oct. 7, 2026, in Frontiers in Public Health, found that waking three or more times a night to urinate was linked to higher odds of depressive symptoms (odds ratio 1.83), possibly through poorer…
A review published Oct. 28, 2026, in the Journal of Biological Rhythms found that in Arctic and Antarctic regions, status epilepticus rose as summer days lengthened, and both extreme light and extreme darkness were linked to shorter, more broken sleep.
A Cochrane review published Oct. 13, 2026, of nine trials with 537 adults found that medical cannabis may have little to no meaningful effect on sleep quality or total sleep time in insomnia, with more side effects, and the evidence…
In a study published Oct. 29, 2026, in Chronobiology International, first-year medical students with strong social jetlag who were assigned classes starting at 10:00 a.m. slept longer, had steadier daily rhythms and scored on exams like naturally early students.
A genetic study of UK Biobank data published Oct. 14, 2026, in Sleep found 125 genetic regions shared by insomnia and the inflammation marker CRP, and stronger evidence that insomnia leads to higher CRP than the reverse.
A meta-analysis of 20 studies with 11 681 adults, published Oct. 27, 2026, in Chronobiology International, found that morning affect was linked to better mental health and big daily swings in alertness to worse, while being a night owl showed…
In a study published Oct. 9, 2026, in Sleep, a neural network reading the single-lead ECG recorded during overnight sleep studies predicted 10-year risk of atrial fibrillation, heart failure, stroke and death, beyond standard risk factors.
