A new pooled analysis of two randomized controlled trials provides the strongest causal evidence to date that chronically sleeping less than one’s body needs may directly lead to weight gain. Adults who cut their sleep by roughly 78 minutes per night for six weeks gained nearly half a kilogram in body weight and showed measurable […]

Are there sex differences in the influence of insomnia symptoms and sleep duration on the trajectory of neuromuscular strength decline? A new longitudinal analysis of more than 6,400 older adults reveals that poor sleep does not weaken muscles equally in men and women, insomnia accelerates strength loss in men, while sleeping too long does the […]

Mobile health applications for sleep are now used by millions of consumers worldwide, yet the evidence base supporting their accuracy and clinical utility remains alarmingly thin. A new commentary published in Sleep argues that the field of digital sleep health must confront this gap before consumer-facing tools can be meaningfully integrated into clinical practice. (brief) […]

The Sleeping Brain, Seen Whole Sleep transforms the brain. Slow waves sweep across the cortex, sleep spindles burst in the thalamus, and theta rhythms mark the transition into deeper rest. But for decades, the map of these electrical sleep oscillations has been incomplete. Most human neuroimaging studies have focused on the cerebral cortex, the wrinkled […]

Agreement between automated and manual scoring of level 3 home sleep apnea devices A single-center retrospective study finds that automated scoring of home sleep apnea tests systematically underestimates disease severity, misclassifying nearly half of moderate cases. Lead Home sleep apnea testing (HSAT) has become a cornerstone of obstructive sleep apnea (OSA) diagnosis, offering patients a […]

Lead A non-invasive MRI technique that measures neuromelanin in the brainstem may help identify which patients with idiopathic REM sleep behavior disorder (iRBD) are at risk for dopamine system damage, according to a study published July 6 in Brain Imaging and Behavior. The technique could serve as a radiation-free triage tool, potentially reducing the need […]

In children and adolescents with narcolepsy type 1 (NT1), the severity of excessive daytime sleepiness is driven largely by how poorly they sleep at night, not just by the narcolepsy itself, according to a cross-sectional study of 114 patients published in the Zhonghua Yi Xue Za Zhi (Chinese Medical Journal). The finding challenges a common […]

Three months of balance training significantly improved subjective sleep quality in adults aged 64 to 81, driven by enhanced GABAergic inhibition in the sensorimotor cortex, according to a study published July 5 in The Journal of Physiology. The finding offers a potential non-pharmacological alternative for the nearly half of all adults over 60 who experience […]
