Adults who sleep only three to five hours per day are at higher risk of developing type 2 diabetes, according to a new study. Chronic sleep deprivation cannot be compensated for by healthy eating alone.
People who experience sleep apnea may be more likely to also have memory or thinking problems, according to a preliminary study. The study shows a positive association but did not determine whether sleep apnea causes cognitive decline.
Early riser or night owl, everyone appreciates a good night's sleep. But despite the best of intentions, quality sleep can elude us, sometimes to the point where it can contribute to serious health issues. Now, a new study shows that...
Researchershave found that brain cell activity during sleep is responsible for propelling fluid into, through and out of the brain, cleaning it of debris.
Researchers have investigated whether the body is truly disconnected from the external world during sleep. To do so, they focused on how heartbeat changes when we hear different words during sleep. They found that relaxing words slowed...
It's official. Getting the recommended 7-9 hours of sleep a night is currently out of reach for almost one-third of the population as experts found 31% of adults had average sleep durations outside the recommended range. The global study...
Problems with our sleep and internal body clock can trigger or worsen a range of psychiatric disorders, according to a new review of recent research evidence. The review suggests gaining a better understanding of the relationship between...
A groundbreaking study has shown promising results in improving the quality of life (QOL) and sleep quality in individuals living with memory problems. The research delves into the efficacy of a nonpharmacological approach in a trial...
Migraine is often underdiagnosed and untreated, and even when it is treated, it can be difficult to treat early enough as well as find strategies to prevent attacks. A new study looks at ways to more accurately predict when a migraine...
A combination of cognitive and behavioral strategies, ideally delivered in person by a therapist, maximizes the benefits of cognitive behavioral therapy for insomnia (CBT-I), according to new research. CBT-I is a form of talk therapy,...
New research indicates that the eating disorder anorexia nervosa is associated with being an early riser, unlike many other disorders that tend to be evening-based such as depression, binge eating disorder and schizophrenia.
People who have more disrupted sleep in their 30s and 40s may be more likely to have memory and thinking problems a decade later, according to new research published in the January 3, 2024, online issue of Neurology , the medical journal...
Researchers explored innovative therapeutic strategies that could greatly advance the understanding and management of OSA-related morbidities. A groundbreaking study provides new insights into the treatment of obstructive sleep apnea...
Researchers have found that enlarged perivascular spaces in the brains of babies, caused by an accumulation of excess cerebrospinal fluid, have a 2.2 times greater chance of developing autism later in life.
Scientists have identified a protein in the visual system of mice that appears to be key for stabilizing the body's circadian rhythms by buffering the brain's response to light. The finding advances efforts to better treat sleep...
Light in the evening is thought to be bad for sleep. However, does the color of the light play a role? Researchers compared the influence of different light colors on the human body. The researchers' findings contradict the results of a...
Researchers have shown that the rare D-form of the amino acid alanine shows a clear circadian rhythm, and is able to affect the circadian clock and regulate gluconeogenesis, a method of glucose release, in the kidney. D-alanine...
In Finland, there is a clear increase in the number of sick days taken due to depression, anxiety and sleep disorders in October and November, whereas the number of absences is lower than expected between June and September. In late...
Researchers have investigated how sleep affects memory. They found a link between breathing and the emergence of certain brain activity patterns in sleep that are associated with the reactivation of memory contents. The data points to...
Blue light from LED lamps and consumer electronics can mess with your sleep because it disrupts production of the natural sleep hormone melatonin. Tinted glasses or displays in night mode can mask, but don't remove, a portion of the...
People who have very irregular sleep patterns may have a higher risk of dementia than those who have more regular sleep patterns, according to new research. The study does not prove that sleep irregularity causes dementia. It only shows...
People who are very sleepy during the day, despite a good night's rest, may have a sleep disorder called idiopathic hypersomnia. New research has found this neurologic disorder may not be as rare as once thought.
Practicing yoga nidra -- a kind of mindfulness training -- might improve sleep, cognition, learning, and memory, even in novices, according to a pilot study. After a two-week intervention with a cohort of novice practitioners, the...
New research reveals that neurons in the preoptic hypothalamus -- the region of the brain that regulates sleep and body temperature -- are rhythmically activated during non-rapid eye movement sleep (NREM). Stress activates these brain...
