“The discussion also explains why sleep and metabolic health belong in the same prevention framework. Deep sleep activates glymphatic clearance of metabolic waste, while impaired brain glucose metabolism is one feature of Alzheimer's disease.”

“Sleep is critical to human survival. Sleep deprivation has marked effects on glucose metabolism. Even a single night of partial sleep deprivation can induce insulin resistance and raise blood glucose levels. In this clip, Dr. Rhonda Patrick describes her personal experience with sleep deprivation and her subsequent altered metabolism.”

“Reducing our late-night exposure to blue light is crucial for a good night's sleep. Limiting screen time or wearing blue light-filtering glasses can help. In this clip, Dr. David Sinclair describes his personal sleep habits for optimal performance during his workday.”

“CBT-I improves HbA1c, blood pressure, sleep quality, sleep duration, and insomnia symptoms in adults with cardiometabolic syndrome. It involves: Stimulus control: Associating the bedroom with sleep and avoiding non-sleep activities in bed.”

“Sleep restriction can also impair glucose control. In a study of 24 healthy young men, five nights with a four-hour sleep opportunity reduced glucose tolerance and altered skeletal-muscle mitochondrial function.”

“The immediate skill is learning to shift deliberately from effort and planning into deep relaxation. Dr. Huberman describes using ten- to thirty-minute sessions during the day, before sleep, or after waking during the night.”

“A good night's sleep requires four elements, or "pillars," including depth – reflected in the electrical quality of the sleep waves; duration – a sufficient amount of sleep; continuity – uninterrupted sleep; and regularity – a pattern of falling asleep and waking at the same time every day.”

“A meta-analysis of randomized sleep-restriction trials found an overall reduction in insulin sensitivity, while the response varied across protocols and participants. A small randomized crossover study tested whether sprint intervals could help after one night with only four hours of sleep.”

“Small randomized crossover trials of amber lenses report mixed results, with one insomnia study finding subjective and actigraphy improvements and another healthy-adult study finding subjective changes without objective sleep improvement.”
