Young people who prefer to stay up late are more impulsive than their peers who go to bed earlier, which makes them more likely to drink alcohol and smoke.
Chronic sleep disruption during adolescence can lead to depression in both males and females and alters stress reactivity in females, according to a new study. Their findings are particularly relevant in the context of a pandemic when...
New parents often expect their baby to start sleeping through the night around the time they reach six months of age. But according to a new study parents should view sleep consolidation as a process, instead of a milestone to be...
Medical researchers in South Australia assessed more than 600 men aged over 40 to 88 years to measure the link between sleep apnea and muscle mass with grip strength.
Researchers have found a new neural pathway that links the circadian clock, stress, and wakefulness in mammals. They identified a neuron that becomes excessively active when the mammal is under stress, which could trigger insomnia and...
Researchers used a cocktail of antibiotics to deplete gut microbes in mice. They found that metabolites in the gut differed in these mice compared with controls. In particular, metabolic pathways involved in making important...
A study found a significant increase in the number of online search queries for 'insomnia' between April and May 2020, when governments across the U.S. and around the world implemented stay-at-home orders in response to the COVID-19...
Reports of racial discrimination against Asians and Asian-Americans have increased since the start of the COVID-19 pandemic hit the United States, coinciding with an increase in reported negative health symptoms, according to researchers.
Determining a child's best daily balance of sleep, activity and relaxation can be a challenge, but if you're hoping to improve their academic results, then it's time to cut back on chores and chill time, according to new research.
People with delayed sleep phase disorder are unable to fall asleep until late at night (often after 2 a.m.) and have difficulty getting up in the morning. In 2017, scientists discovered a surprisingly common mutation that causes this...
Increasing the amount of time spent asleep immediately after a traumatic experience may ease any negative consequences, suggests a new study conducted by researchers. The study helps build a case for use of sleep therapeutics following...
More than half of young adults at risk for alcohol-related harm report symptoms of insomnia. Cognitive behavioral therapy (CBT) is one of the first-line treatments for insomnia, but it's never been tested on young adults who are actively...
During the pandemic, the amount of screen time for many people working and learning from home as well as binge-watching TV has sharply increased. New research finds that wearing blue-light glasses just before sleeping can lead to a...
A review of 39 randomized clinical trials has found that combining the use medication with psychoeducational therapy is more effective at preventing a recurrence of illness in people with bipolar disorder than medication alone.
The brain is assumed to exert homeostatic functions to always keep the cellular energy status constant, this has not been proven. Researchers discovered that cortical neuronal intracellular concentrations of ATP, the major cellular...
In the United States, the average American sleeps less than the minimum seven hours of sleep per night recommended by the Center for Disease Control, and nearly half of Americans report negative consequences from insufficient sleep. This...
People with generalized epilepsy who have seizures arising from both sides of the brain simultaneously, have a higher risk of obstructive sleep apnea (OSA) compared to patients who have focal epilepsy where seizures emanate from one area...
New research shows damage in the brain starts in the same place and spreads in the same way in sleep apnea, as in Alzheimer's disease. The study is the first to find Alzheimer's-like amyloid plaques in the brains of people with...
During the initial phase of COVID-19 lockdown, rates of loneliness among people in the UK were high and were associated with a number of social and health factors, according to a new study.
A new study suggests that star-shaped brain cells known as astrocytes could be as important to the regulation of sleep as neurons. The study builds new momentum toward ultimately solving the mystery of why we sleep and how sleep works in...
Obstructive sleep apnea (OSA) affects more than one billion people worldwide. Evidence suggests OSA can alter the gut microbiome (GM) and may promote OSA-associated co-morbidities, including diabetes, hypertension and cognitive problems....
Weighted blankets are a safe and effective intervention in the treatment of insomnia, according to researchers who found that insomnia patients with psychiatric disorders experienced reduced insomnia severity, improved sleep and less...
Insomnia causing sleepless nights, daytime fatigue and poor health outcomes is a cycle worth busting, experts say, with depression, anxiety and stress a common co-occurrence. A study of more than 450 insomnia patients in Australia has...
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...
New research 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...
Neuroscientists have found a way to estimate, with some degree of accuracy, a time frame for when Alzheimer's is most likely to strike in a person's lifetime, based on their baseline sleep patterns. Their findings suggest one defense...
Researchers have found associations among disrupted sleep, elevated blood pressure and changes in the gut microbiome. The research aimed to determine whether a 28-day period of disrupted sleep changed the microbiota in rats. The...
