“Researchers reviewed the findings of 18 studies involving more than 1,800 men that examined links between sleep apnea and male testosterone levels. Then they analyzed a subset of the studies after matching the men's age, body mass index, and severity of their sleep apnea.”

“In both trials, participants followed two six-week sleep schedules in a random order: one with their usual sleep and one with bedtime delayed by 1.5 hours. Wrist sensors confirmed that the shorter sleep period reduced nightly sleep by about 78 minutes, to just over six hours.”

“They also completed the Sport Concussion Assessment Tool–3rd Edition (SCAT3) symptom evaluation as part of baseline preseason testing. The SCAT3 is a self-reported inventory of 22 symptoms and includes questions about the number of hours of sleep obtained the night before testing.”

“Interestingly, the increased “munching” was associated with an increase in the levels of an endocannabinoid called 2-AG, which was about 33% higher in the sleep-deprived people.”

“The effects of lost sleep on memory may depend partly on how well brain cells control inflammation and maintain their energy supply. Researchers tested whether urolithin A, a compound made by gut microbes from food components, could protect memory in mice when given before sleep deprivation.”

“Selecting products tested for chemical emissions and maintaining adequate ventilation may help reduce potential exposure. In this clip, Dr. Andy Galpin explains how elevated bedroom CO2 levels can disrupt sleep and outlines proven strategies to reduce them.”

“Other clinical trials have shown that poor sleep (4 hours a night for 2 nights) can result in 20% higher circulating insulin levels. 100 lux is similar to a dim family room light and is quite a bit of light to be exposed to during sleep hours.”

“The investigators interrupted the sleep of normal mice and mice that lacked TLR-4, mimicking the effects of several sleep disorders. After the mice developed cancer, the investigators noted characteristics of the animals' tumors, including size, invasiveness, and the type and number of tumor-associated macrophages.”

“Regular sleep, meals, hydration, and stress management can reduce common triggers. In a randomized trial of 196 adults, three milligrams of melatonin nightly reduced migraine days more than placebo over three months and caused fewer adverse effects than amitriptyline.”

“FTA: > A new study reports that sleep efficiency, a ratio of time asleep to time spent in bed, is predictive of survival time for women with advanced breast cancer. According to the authors, this is the first study to demonstrate the long-term detrimental effects of objectively quantified sleep on survival in women with advanced cancer.”
