“Many adults struggle with daytime sleepiness and nighttime insomnia, impairing memory, mood, and focus. Several factors regulate sleep and wake activities, including central and peripheral circadian rhythms and timing of meals.”

“Lack of sleep has been shown to accelerate telomere shortening in several studies in adults but this is the first study looking at telomere length in children. According to the author of this study, the current recommendation is for such children to get between 9 and 11 hours of sleep.”

“Roughly half of all deaths in developed countries are attributed to atherosclerosis. A new study suggests that a pro-inflammatory pathway triggered by poor sleep contributes to the risk of developing atherosclerosis.”

“Whereas some nucleotides peaked during the day, others peaked at night, suggesting a potential role for these nucleotides as sleep inducers. Breast milk is species-specific, containing nutritional and non-nutritional components tailored to serve the infant's varied needs.”

“Researchers used actimetry, brain activity recordings, and self-reported questionnaires to measure the participants' sleep patterns. They also assessed their mood, anxiety, and heart rate variability during the nights following each condition.”

“For sleep, passive heating has more direct support: a warm bath or shower one to two hours before bed can improve subjective sleep quality and shorten sleep-onset latency. Cold immersion requires a gradual approach, supervision, a safe exit, and extra caution for people with cardiovascular or pulmonary conditions.”

“The experiments examine short-term hormonal responses under controlled conditions, helping explain why sleep history and testing conditions matter when interpreting testosterone levels. Dr. Patrick also explores fertility trade-offs associated with deliberate heat exposure and exogenous hormones.”

“A recent study found that synchronized fluctuations in norepinephrine, blood volume, and cerebrospinal fluid are key drivers of glymphatic clearance during deep sleep, but some popular sleeping pills disrupt this process.”

“People with bipolar disorder are sensitive to fluctuations in circadian patterns, including sleep deprivation and time zone changes. Chronotherapy, which involves maintaining regular sleep/wake cycles, has been used as a treatment for bipolar disorder.”

“They completed this study visit twice in random order, once after a full night of rest and once following a night of total sleep deprivation. Sleep-deprived participants reported feeling sleepier and performed significantly worse on cognitive tests prior to exercise.”
