Researchers in this observational study investigated the association between the amount of sleep at night and cognitive decline among participants in two large studies on aging.

Early to bed, early to rise...while the old saying promises health, wealth and wisdom, new research confirms part of the adage holds true, as a world first study shows that people who go to bed early are more likely to be in better health and more physically active compared to night owls.

Using data from humans and other mammals, a team of scientists including researchers from the Santa Fe Institute has developed one of the first quantitative models that explains why sleep times across species and during development decrease as brains get bigger. Crucially, the model identifies a sharp transition at around 2.4 years of age, where sleep patterns change in humans as the primary purpose of sleep shifts from reorganization, which is essentially learning, to repair.

For people with chronic insomnia, a good night's sleep is elusive. But what if insomnia symptoms could be alleviated by simply listening to one's own brainwaves?

Repetitive head impacts are associated with development of the neurodegenerative disease chronic traumatic encephalopathy (CTE). Some individuals diagnosed with CTE after death were reported to suffer from sleep dysfunction, but the type of disorder and its cause has never been formally explored.

New research from UBC finds that after a night of shorter sleep, people react more emotionally to stressful events the next day--and they don't find as much joy in the good things. This has important health implications: previous research shows that being unable to maintain positive emotions in the face of stress puts people at risk of inflammation and even an earlier death.

People who have been diagnosed with obstructive sleep apnoea could be at increased risk of adverse outcomes from COVID-19 according to a new study from the University of Warwick.

MIT researchers have developed a wireless, private way to monitor a person's sleep postures -- whether snoozing on their back, stomach, or sides -- using reflected radio signals from a small device mounted on a bedroom wall.

Emerging evidence suggests that obstructive sleep apnea (OSA) may negatively affect bone health. Results from a new study published in the Journal of Bone and Mineral Research now indicate that women with history of OSA may face a higher risk of spine, or vertebral, fractures.
