People with breathing problems during sleep may have a larger hippocampus, the area of the brain responsible for memory and thinking, according to a new study. The study, which included mostly Latino people, also found that those with...
Just as a conductor coordinates different instruments in an orchestra to produce a symphony, breathing coordinates hippocampal brain waves to strengthen memory while we sleep, reports a new study. This is the first time breathing rhythms...
It has been known for nearly 20 years that slow, synchronous electrical waves in the brain during deep sleep support the formation of memories. Why that is was previously unknown. Now, a team of researchers posits an explanation....
Sleep is critical for all sorts of reasons, but a team of international scientists has discovered a new incentive for getting eight hours of sleep every night: it helps the brain to store and learn a new language.
Circadian clocks control physiological processes and behavior in virtually all living organisms. Now an international research team has created a detailed map of the internal clock in the brain of the fruit fly.
Being lonely is a bigger hurdle to a good night's sleep for college students than too much time at a computer or other electronic screen, a new study suggests.
A research group has discovered that in mammals, a protein kinase A (PKA) promotes wakefulness, while protein phosphatase 1 (PP1) and calcineurin promote sleep. This study revealed that the balance between sleep and wakefulness is...
You may have heard sleep described as something of a magic pill for the body. With the right amount, timing, and quality, it can work wonders -- strengthen the immune system, improve blood sugar, even decrease the risk of heart attacks...
While it's well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related to nonrapid eye movement (NREM) sleep, remain largely unexplored. A new study has nonetheless uncovered a key...
Adolescents who snore frequently were more likely to exhibit behavior problems such as inattention, rule-breaking, and aggression, but they do not have any decline in their cognitive abilities, according to a new study. This is the...
Have you ever felt sluggish and out of sorts after a long-haul flight or a late-night shift? A new study has found that disruptions to our body clock, such as those experienced during jetlag, impact our metabolism -- but to a lesser...
Scientists reveal how sleep, especially naps, boosts motor learning after TBI, offering new insights into brain activity and rehabilitation strategies to enhance recovery outcomes.
Adolescents who meet the recommended guidelines of nine to 11 hours of sleep per day were shown to have a significantly lower risk of hypertension, according to a study.
A consistent bedtime may be more important to a child's ability to control their emotions and behavior than the duration or quality of their sleep, according to a new publication.
Older people who are sleepy during the day or lack enthusiasm for activities due to sleep issues may be more likely to develop a syndrome that can lead to dementia, according to a new study.
CBT for insomnia significantly reduces postpartum depression symptoms, directly and indirectly, by improving mood and alleviating insomnia throughout treatment.
Sleep apnea, a common yet underdiagnosed sleep disorder, contributes to the development of dementia among adults -- particularly women, a new study suggests. At every age level, women with known or suspected sleep apnea were more likely...
With the clocks going back this weekend, a new study has found that moving the clocks one hour forward in Spring and one hour back in Autumn has a substantial, but short-lived effect on sleep duration.
Researchers show how sleep loss during early life impacts key aspects of brain development and how it can increase one's risk for developing autism spectrum disorder.
People in early middle age who have poor sleep quality, including having difficulty falling or staying asleep, have more signs of poor brain health in late middle age, according to a new study. The study does not prove that poor sleep...
A new study has demonstrated a new way to treat narcolepsy-related nightmares. The scientists combined cognitive behavioral therapy (CBT) and lucid dreaming to help patients in a small clinical trial.
A team of sleep researchers called for the government to abolish the twice-yearly clock changes in the UK due to the adverse effects on sleep and circadian health.
A world-first randomised controlled trial (RCT) of toddler screen time shows that removing screen time in the hour before bed improves the quality of toddler sleep.
In a study of commonly used treatments for multiple sclerosis, both medical and behavioral interventions, and a combination of the two, resulted in significant improvements in fatigue. Researchers say the findings could shape treatment...
Australian researchers have identified a new, brain-based measure of chronic sleepiness that could be diagnosed in just two minutes, predicting whether someone is safe to drive, operate machinery, or even alert enough to sit an exam.
Scientists have discovered the secret to regulating our internal clock. They identified that this regulator sits right at the tail end of Casein Kinase 1 delta, a protein which acts as a pace setter for our internal biological clock or...
The use of circadian-informed lighting, where artificial lighting is synchronised to the natural biological rhythms or a person's 'body-clock', significantly improves quality of sleep and work performance for night shift workers, a major...
A research team combined measurements from activity monitors and questionnaires for a new study of impact of aircraft noise on sleep. Higher levels of noise were associated with disturbed sleep quality measured by activity monitors....
A significant breakthrough in the understanding of sleep mechanism opens new promise for treating sleep disorders and associated neuropsychiatric conditions: Scientists have pinpointed the melatonin receptor MT1 as a crucial regulator of...
People who have had a stroke may be more likely to sleep too much or too little compared to those without prior stroke, according to a new study. The study does not prove that stroke causes abnormal sleep; it only shows an association.
Group sleeping can impact when animals sleep, how long they sleep for, and how deeply they sleep. For example, groups of meerkats time their sleep according to 'sleep traditions'; olive baboons sleep less when their group size increases;...
A new study has found that regular mobile phone use was positively associated with incident cardiovascular diseases risk. In addition, this association was partly attributed to poor sleep, psychological distress, and neuroticism.
Despite what we've been led to believe, the timing of evening screen use, rather than the activity itself, negatively impacts youth sleep, a new study has found.
Modern lifestyles mean many people are sleep deprived on work or school days, and try to 'catch-up' with compensatory sleep on weekends. A new study of more than 90,000 individuals showed that those who had the most catch-up sleep on...
New research reveals harmful consequences for people who are overweight and ignore their body's signals to sleep at night, with specific differences between men and women.
Computer science researchers have developed an approach that matches the performance of expert-scored polysomnography using just a single-lead echocardiogram. In addition to simplifying a typically expensive and cumbersome process, this...
Two new studies are pointing the way toward round-the-clock personalized care for people with Parkinson's disease through an implanted device that can treat movement problems during the day and insomnia at night.
A study has uncovered significant findings related to the early sensorimotor features and cognitive abilities of toddlers who are later diagnosed with autism spectrum disorder (ASD).
They're the little digital tools you can download in a few seconds, but despite their literal size, health and fitness apps pack a real punch when it comes to getting results, say researchers.
Adolescents were more likely to have consumed alcohol or tried marijuana by age 15 if they had later bedtimes and slept fewer hours during the night during childhood and adolescence, according to a new study.
Currently, the first-choice treatment for PTSD is exposure-based psychotherapy, where therapists help rewire the emotions associated with the traumatic memory in the patient's brain, shifting from fear and arousal to a more neutral...
