Sleep science, research & sleep medicine news
Twenty-one days of constant light suppresses liver protein production by roughly 16% and decimates key circadian clock proteins, but the hormone melatonin fully reverses the damage in both sexes, according to a study published July 4 in Biology of Sex Differences. The findings carry direct implications for shift workers, frequent long-haul travelers, and anyone living […]
A retrospective analysis of 12,036 obstructive sleep apnea patients at a single sleep center finds that two-thirds, 66.3%, have positional OSA (POSA), defined as a supine apnea-hypopnea index at least double the non-supine AHI. Published July 4 in Sleep & Breathing, the study provides one of the largest characterizations of POSA’s clinical and polysomnographic signature […]
New brain imaging evidence shows that insomnia complicated by anxiety selectively damages the peripheral connections of the brain’s structural network while sparing its central “rich club” hub architecture. The study, published June 30 in Psychiatry Research: Neuroimaging, provides the clearest picture yet of how white matter integrity breaks down in patients suffering from both conditions […]

Why Sleep Science Needs to Wake Up to Neurodivergent Brains For the estimated 15% to 20% of the global population who are autistic, have ADHD, or otherwise diverge from the neurotypical standard, disrupted sleep and irregular circadian rhythms are a near-constant companion. Yet despite decades of research on autism, ADHD, sleep, and mental health in […]
Every bodybuilder knows the feeling: a deep, restorative night of sleep, and you wake up stronger. Every teenager who has ever been told to go to bed knows it too: growth happens when you sleep. But the mechanism behind this ancient link between sleep and growth has remained a mystery of neuroscience for decades. Now, […]
Can Better Sleep Sharpen Your Eyes? Study Links Insomnia Treatment to Improved Eye Movements A new study suggests that treating insomnia in older adults may do more than help them sleep, it could improve the way their eyes move during waking hours. Researchers in Japan have found that improvements in sleep quality and daytime sleepiness, […]
When sleep aids rewrite the night: How common medications may reshape what we remember You take a pill before bed. An antidepressant for mood, a sedative for sleep, an anesthetic before surgery. You sleep through the night and wake up feeling fine. But what happened to your memories while you were under? A new systematic […]
The warning in the dark: Nightmares may foreshadow suicidal crisis by months A new study from Paris suggests that nightmares, especially those with suicidal themes, can emerge weeks to months before a person reaches psychiatric emergency care, offering clinicians a potential early warning signal for imminent suicide risk. Published in Sleep Medicine, the prospective study […]
Sleep deprivation impairs gastric ulcer healing and induces anxiety-like behavior in rats New research reveals that missing sleep while recovering from a gastric ulcer not only stalls healing but also drives anxiety and brain damage, raising urgent questions about sleep management in hospitalized patients. A study published in BMC Research Notes has demonstrated that total […]
