“The decline of deep, slow-wave sleep begins early in life, and by the time a person is in their 80s, their deep sleep brain waves are almost undetectable. The fact that poor sleep is linked with the aggregation of amyloid-beta plaques in the brain and Alzheimer's disease is not surprising.”

“One theory is that this eating pattern coordinates food intake with the body's peak metabolism period. Time-restricted eating can promote better sleep, and sufficient sleep itself can improve some biomarkers, creating a virtuous cycle.”

“Conversely, healthy behaviors, such as getting plenty of sleep and practicing time-restricted eating, reduce the risk of arrhythmias. In this clip, Dr. Satchin Panda describes how lifestyle factors influence the risk of heart arrhythmias.”

“Studies consistently show that a lack of sleep—even just a single night—can reduce insulin sensitivity by up to 25% in healthy young adults. A lack of sleep fits under the "stress" category of the three primary causes of fast insulin resistance (the other two being inflammation and excessive insulin).”

“The Wild 5 protocol is an example of an online-based resource that combines exercise, nutrition, sleep, social connectedness, and mindfulness practices. The program, which allows individuals to track their behavior and receive feedback, is easy to use.”

“Older adults and neonates have blunted circadian rhythms that markedly reduce the duration and quality of their sleep. Artificially modulating those rhythms through modification of light exposure can normalize circadian rhythms and improve cognitive performance in older adults and oxygen saturation and weight gain in infants.”

“Events experienced during periods of wakefulness trigger the activity of different neurons in the brain. During sleep, the brain "relives" those events by triggering the activity of the same neurons – at 10 to 20 times the original speed.”

“For adults with diagnosed insomnia, melatonin appears less effective, with little to no improvement in sleep duration, sleep onset latency, or sleep efficiency. However, for children and adolescents with insomnia, melatonin improves both sleep onset latency and total sleep duration.”

“Light during sleep produces immediate metabolic strain Light can alter nighttime physiology even when melatonin does not change. A single night at 100 lux, roughly the brightness of a dim family room, increased a marker of insulin resistance by about 15% among 20 healthy adults.”

“More wakefulness in the second half of the night. People with sleep apnea should especially avoid alcohol close to bedtime. Alcohol can worsen sleep apnea by relaxing the genioglossus muscle (the muscle that prevents the tongue from blocking the airway).”
