Sleep

Cannabinol (CBN), a mildly psychoactive cannabinoid marketed as a natural sleep aid, did not significantly reduce wake after sleep onset (WASO) in a rigorous randomized controlled trial. However, the higher dose tested improved several secondary measures of sleep quality. Lead CBN has gained popularity as a non-prescription sleep supplement, often sold in oils, gummies, and […]

A new study from the University of Haifa provides the first real-world evidence quantifying how artificial light at night (ALAN) and noise together degrade sleep quality in adolescents. The findings show effects roughly twice as large as those previously reported in adults. What they found Researchers recruited 81 adolescents aged 13 to 18 living in […]

Dietary counseling for patients with cardiovascular disease (CVD) improved diet quality over six months, but this did not translate into better sleep outcomes, according to a secondary analysis of a randomized controlled trial published in the Journal of Sleep Research. The Study Verkaar and colleagues conducted a secondary analysis of a six-month, two-arm, parallel randomized […]

Noise-induced wakefulness traced to a thalamic-septal circuit in mice For millions of people who live near traffic, construction, or noisy neighbors, the experience is all too familiar: a sudden sound jolts you from sleep, and you lie awake wondering if you will drift back off. A study published July 2 in iScience now identifies the […]

Circadian clock gene homolog shapes neural circuit development in C. elegans, but developmental sleep may not be essential Sleep is widely assumed to be essential for brain development. Across the animal kingdom, from worms to humans, developing brains spend large portions of time in a sleep-like state, and disrupting sleep early in life has been […]

Lead. A large web-based survey in Japan has found that underweight women in their 20s are more likely to report insomnia symptoms, but the same link does not appear in adolescent girls or in women over 30. The finding represents one of the first efforts to document an age-specific relationship between underweight and sleep problems […]

For decades, napping research has relied on a deceptively simple question: do you nap or not? In a new perspective piece published in Sleep Health, chronobiology researcher Marta Garaulet (University of Murcia, Brigham and Women’s Hospital/Harvard) and co-author M. Rodriguez-Martin argue that this binary approach obscures the complex relationship between daytime sleep and health outcomes. […]

Many students have an intuitive habit: a quick glance at their notes just before turning off the light. New research suggests this simple practice may be more powerful than previously thought. A study published in Sleep Medicine X finds that briefly re-reading a text for just one minute before falling asleep actively boosts memory consolidation, […]

For three decades, researchers have tried to see what the brain does during sleep, not just which electrical rhythms pulse across the scalp, but which deep structures light up and fall silent across the night. The challenge has been technical: electroencephalography (EEG) captures millisecond-scale changes in cortical activity but cannot localize them subcortically, while functional […]
