A new study links rising temperatures to reduced sleep quality and length in US adults, particularly those living on the West Coast. The research estimates that by 2099, people could lose up to 24 hours of sleep each year due to heat, highlighting the potential impact of climate change on sleep health.
A new study found that fragmented sleep worsens symptoms of traumatic brain injury and decreases rapid-eye-movement (REM) sleep. Injured mice failed to compensate for lost REM sleep, leading to increased fatigue and decreased activity. The research highlights the critical role of uninterrupted sleep in brain injury recovery.
A recent study from the University of Toronto found that use of pre-workout dietary supplements is associated with five or fewer hours of sleep per night. The study analyzed data from over 16-30 year-old participants and found that those who used pre-workout supplements were more than twice as likely to report short sleep durations.
Researchers found that short and irregular weekday sleep significantly disrupts glucose metabolism, increasing type 2 diabetes risk. Even with extended weekend sleep, the body's ability to process glucose is impaired. Regular sleep patterns are crucial for glucose regulation and may impact the development of insulin resistance.
A trial from Hong Kong found that tai chi is comparable to cognitive behavioural therapy (CBT) in reducing symptoms of chronic insomnia. The study showed that tai chi was non-inferior to CBT at the 12-month follow-up, suggesting its potential as an alternative treatment approach for middle-aged and older adults.
A study of over 27,000 collegiate athlete sleep records found that early morning team practices lead to reduced sleep time and lower sleep efficiency scores.

The research analyzed data from a large international database and found consistent and significant increases in serious health outcomes, even after balancing for other risk factors.
Researchers at UMass Amherst have developed an app that uses Apple Watch data to monitor sleep stages and predict Alzheimer's disease risk. The app, BIDSleep, collects heart rate data and feeds it into an AI model that accurately identifies sleep stages 71% of the time.
Researchers found that sleep-deprived individuals experience attentional failures coinciding with a flushing of CSF from the brain. During these lapses, physiological changes occur, including a flux of CSF out and then back in. The study suggests that the brain attempts to compensate for lost cleansing by initiating pulses of CSF flow.
A major study published in the European Respiratory Journal found that heatwaves increase the risk of moderate-to-severe obstructive sleep apnoea (OSA) by 13% during peak heatwave periods. The risk is higher when humidity is also high, with a 1.1% increase for every 1°C rise in nighttime temperature.
Poor sleep quality affects over 1 in 5 residents in long-term care facilities, leading to increased medication use, falls, and delirium. Modifiable risk factors like pain management, medication review, and improved sleep routines can help mitigate these issues.
Obstructive sleep apnea is increasingly being diagnosed in younger adults, challenging the stereotype that it only affects older or overweight individuals. Many people with sleep apnea remain undiagnosed due to daytime fatigue and overlooked symptoms like snoring or choking.
A new study using next-generation imaging technology discovered that when the brain is falling asleep, it shows a coordinated shift in activity. Areas involved in thinking, memory, and daydreaming quiet down and use less energy during NREM sleep.
Researchers identified a link between early adolescence sleep disruption and later suicide attempts. Adolescents who experienced difficulties maintaining and obtaining sufficient sleep were more likely to report a suicide attempt several years later.
A new study from UC San Francisco found that saturated fat affects the behavior of a protein called PER2, which orchestrates fat metabolism and circadian rhythms. Mice eating a diet high in hydrogenated fats struggled to adapt to winter, whereas those on unsaturated fat diets adjusted easily.
A new UTA study found that engaging in light activity, such as walking or doing chores, instead of sitting can lead to better feelings the next day. The research, published in Psychology of Sport and Exercise, suggests that even small changes to daily routine can have a positive impact on mood and energy.
A new study reveals that rising temperatures are causing widespread reductions in sleep duration across the globe, with warmer nights resulting in an average loss of 15-17 minutes of sleep. This is particularly concerning as the likelihood of experiencing short sleep increases by approximately 40% during heatwaves.
Eight finalists compete in November for the award, with innovations including non-invasive sleep studies and treatments for obstructive sleep apnea. The AASM's Sleep Medicine Disruptors event will be held in Austin, Texas, on November 14-15.
Researchers have discovered that deep sleep plays a crucial role in controlling cerebrospinal fluid dynamics, which is essential for clearing waste from the brain. During slow-wave sleep, changes in cerebrospinal fluid signals are time-locked to slow brain waves and other neural events.
A study published in PLOS Biology found that surgically disconnected neural tissue in epilepsy patients exhibits slow-wave patterns similar to those observed during deep sleep or anesthesia, suggesting absent or reduced awareness. The persistence of these patterns raises questions about the functional role of slow waves in the brain.
Researchers found that instructions improve recall more than emotional associations, but sleeping doesn't significantly impact memory. They discovered that sleep spindles are linked to better recall of negative words, while slow wave sleep negatively correlates with total recall.
Researchers identified five distinct sleep-biopsychosocial profiles, each associated with a unique pattern of brain connectivity. The study revealed that different aspects of sleep are related but can also be separable domains influencing biopsychosocial factors.
A study found that longer commutes and smaller living spaces are associated with poor sleep health among Tokyo residents. Housing choices that balance location and size may help improve sleep health, according to researchers at Osaka Metropolitan University.
