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 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.

Mice carrying the faulty gene exhibited depression-like symptoms when exposed to short light periods, mirroring human seasonal affective disorder.
During sleep, brain activity patterns from the day are replayed at fast-forward speed in the hippocampus, strengthening microscopic connections between nerve cells. This process is crucial for consolidating memories and retaining important information.
Researchers have identified a specific gene mutation that appears to link unusual sleep patterns and Seasonal Affective Disorder (SAD). The PER3 gene mutation was found in family members with both conditions, suggesting a connection between circadian genes and mood disorders.
Research found that sleeping seven to eight hours per night reduces stroke risk by 25%, while excessive long sleep increases the risk by 146%. Regular exercise of 30-60 minutes, three to six times a week, also significantly decreases stroke risk. A computerized analysis of health data from 288,888 adults revealed these key findings.
Researchers discovered a gene, neuromedin U, that promotes wakefulness and suppresses sleep in zebrafish. The protein's function suggests it may be nature's alarm clock, helping to regulate the transition from nighttime sleep to daytime wakefulness.
Researchers identified a gene, neuromedin U (Nmu), that regulates sleep in zebrafish. Overexpression of Nmu causes severe insomnia, while its absence leads to reduced activity during the day. The study improves understanding of sleep regulation and suggests Nmu as a potential candidate for new therapies to address sleep disorders.
A new study of firefighters suggests that insomnia and nightmares may increase the risk of depression by impairing emotion regulation strategies. The study found that limited access to these strategies, such as problem-solving skills and negative emotions decrease, was the strongest indirect effect for both relationships.
A recent study from the University of Missouri found a strong association between difficulty sleeping and behavioral problems in children with Autism Spectrum Disorder (ASD). The research, which surveyed parents of 81 children with ASD, revealed that sleep difficulties are highly related to daytime behavioral issues such as aggression,...

The study found that this method can speed up the brain's adjustment to time changes, reducing the delay in onset of sleepiness.
A new study from Brigham and Women's Hospital found that circadian misalignment increases blood pressure and inflammatory markers in healthy adults. Researchers measured these factors in 14 participants during two eight-day stays in the sleep laboratory, one with circadian alignment and the other with misalignment.
A study of 678 women found that frequent bed-sharing with infants and a strong motivation to breastfeed were linked to longer breastfeeding durations. This challenges recommendations against bed-sharing due to SIDS fears, suggesting these practices may hinder some mothers from achieving their breastfeeding goals.
A study found that both short and long sleep durations in pregnancy are associated with extreme gestational weight gain. Poor sleep has been linked to adverse pregnancy outcomes, and the study provides a potential mechanism for this association.
Research suggests that frequent shifts in sleep timing are associated with higher insulin resistance and body mass index (BMI) in midlife women. Irregular bedtimes were linked to impaired glucose regulation, while consistent sleep schedules showed better metabolic health.

The research found that drivers hit a rumble strip after 20 minutes of driving and that taking breaks and using countermeasures like napping or caffeine can increase driver alertness.
Researchers found that diet-induced obesity mice eating a low-fat diet for eight weeks followed by just one week of high-fat diet had improved sleep profiles compared to those maintaining the high-fat diet. The findings suggest that changes in weight are more important than body weight itself in regulating sleep.
