A new study from The Ohio State University College of Public Health found that preschoolers who are regularly tucked into bed by 8 p.m. are far less likely to become obese teenagers than young children who go to sleep later in the evening. Bedtimes after 9 p.m. appeared to double the likelihood of obesity later in life.
Preschoolers who go to bed by 8 p.m. are half as likely to become obese teenagers as those who turn in late, according to a study from The Ohio State University College of Public Health. Establishing an early bedtime routine can also have positive benefits on behavior and cognitive development.
Research reveals that king penguins can distinguish between dangerous and benign sounds while sleeping on the beach. They react with alarm to predator calls, but not to unfamiliar sounds like a dog's growl.
A new study found that both limited and excess sleep may raise diabetes risk in men, with those sleeping too much or too little having impaired glucose metabolism. In contrast, women who slept less or more than average were more responsive to insulin and had enhanced beta-cell function.
Researchers found that teaching parents bedtime techniques can improve infants' sleep-related behaviors, leading to longer sleep duration and reduced rapid weight gain. Establishing good sleep habits early in life is crucial for preventing obesity and promoting emotional health.
A new study found that adolescents who get insufficient sleep experience increased variability in sadness, anger, and energy levels. Healthy teens who restrict their sleep have worse moods the next day, while those with higher daily mood scores predict poor sleep quality the following night.

The research highlights the importance of screening for sleep disturbances and providing evidence-based interventions to service members and their families.
A new study found that police officers who work day shifts perform better in interactions with the public, while those working night shifts are more likely to have encounters escalate into violence. The research suggests that better fatigue management could improve officers' ability to manage encounters effectively.
Researchers analyzed data from 4,221 individuals and found no clear link between sleep disturbing medications and actual sleep problems. The study suggests that patients may be misinformed about the side effects of certain drugs.
Research by Texas A&M University scientists found that shift workers are more prone to severe ischemic strokes due to disrupted circadian rhythms. Estrogen levels may play a role in protecting women from stroke severity, but men face increased risks, especially after age 50.

The study also showed that poor sleepers are more likely to leave the military early and are less likely to deploy.
A new study published in JAMA Internal Medicine found that telephone-based cognitive behavioral therapy significantly improves sleep quality and reduces insomnia in women through all stages of menopause. The therapy also helps with hot flashes, reducing their interference with daily functioning.
A Finnish study found that one in four professional athletes suffer from significant sleeping disorders, and most athletes slept too little. The study showed that general guidance, examinations when necessary, and personalized treatment plans significantly improved athletes' sleep quality.
Researchers from Austria, Finland, and Hungary used laser scanners to measure the daily movement of fully grown trees. The results show that trees droop their branches at night, with changes not exceeding 10 cm, indicating they go to sleep.
Untreated obstructive sleep apnea (OSA) is associated with a significant increase in major adverse cardiac and cerebrovascular events, including cardiovascular death, heart attack, stroke, and unplanned revascularization. Patients with OSA have a 1.57 times higher risk of these events compared to those without OSA.
Researchers at HRL Laboratories are developing a man-portable system using high-definition transcranial current stimulation (HD-tCS) to tag specific memories and skills during learning. The STAMP method aims to improve consolidation by reactivating neural representations during sleep.
A study found that flame retardants used in tent manufacturing are released into the air within tents, potentially exposing campers to toxic compounds. The levels of these compounds can vary depending on the brand of tent, but may still pose a health risk to adults and children.
A meta-analysis of four studies found an association between swaddling for sleep and Sudden Infant Death Syndrome (SIDS), particularly among infants placed on their sides or fronts. As babies get older, they may be more likely to move into unsafe positions while swaddled during sleep.
Researchers studied 5812 children from five continents to determine if lunar phases affect sleep duration, with a significant 1% decrease in full moon nights. The study found no substantial impact on behavior, contrary to folklore and myths.
A new study published in the Journal of Clinical Sleep Medicine found that women who slept less than 7 hours per night and were frequent snorers before their cancer diagnosis had a poorer prognosis. The study suggests that poor sleep quality may contribute to accelerated tumor growth and shortened cancer survival.
A new study from Aarhus University found that children with ADHD take longer to fall asleep at night and experience more disturbed sleep. The researchers also discovered that children with ADHD tend to fall asleep faster during the day than their peers, which may be a compensatory behavior for not being able to doze off during the day.
A randomized clinical trial found that 25% calorie restriction over two years improved mood, reduced tension, and enhanced general health and sexual drive in healthy adults. The study suggests that calorie restriction may provide some benefits for nonobese individuals, contradicting previous concerns about potential negative effects.
The American College of Physicians (ACP) endorses cognitive behavioral therapy for insomnia (CBT-I) as the primary treatment for adults with chronic insomnia. CBT-I combines cognitive therapy around sleep with various behavioral therapies.
A study published by the American Academy of Neurology found that people with traumatic brain injuries (TBI) experience long-term sleep disturbances, despite not being aware of it. Researchers discovered that 67% of those with TBI suffered from excessive daytime sleepiness compared to 19% of healthy individuals.
A study found that teenage mothers in Colorado were aware of safe sleep guidelines but chose to disregard them due to misconceptions about infant comfort and safety. The researchers suggest innovative public service announcements and improved healthcare provider communication could improve safe sleep behaviors among this high-risk group.
A review of 21 studies on dietary interventions and sleep found significant effects in nearly half of the laboratory-based studies. However, overall findings suggest that a single diet change is unlikely to drastically improve sleep quality for most people.
Researchers discovered that when people sleep in an unfamiliar place, one hemisphere of the brain stays more awake to keep watch. This phenomenon is related to the difficulty a person experiences in falling asleep and can be reduced by bringing familiar comforts.
A new study published in Nutrients found that high-fat diets are associated with increased risk of daytime sleepiness and poor sleep quality in Australian men. The research, which analyzed data from over 1,800 men aged 35-80, also linked high fat intake to a higher incidence of sleep apnea.
A study found that specific psychological and social work factors were consistently associated with sleep problems, both concurrently and two years later. The most consistent predictors of troubled sleep included quantitative job demands, decision control, role conflict, and support from a superior in the workplace.
Researchers at Umea University have discovered an enzyme in the sleeping sickness parasite that can cleave and disarm adenosine analogue pharmaceuticals. This breakthrough enables the development of more efficient drugs, bypassing the parasite's protective mechanism.
A new study found that shifted sleep-wake cycles affect brain function differently in men and women. Women were more cognitively impaired during the early morning hours, making them potentially more vulnerable to night-shift work.
Scientists at University of Maryland School of Medicine identified a key pathway for regulating the 'switch' between wakefulness and sleep. The study found that BK potassium channels play a critical role in encoding circadian rhythm in the brain, particularly during inactivation.
