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.

Researchers discovered a molecular link between mood disorders and circadian rhythms in a study on familial advanced sleep phase (FASP) and faulty PER3 gene variants. 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.

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.
