“In response to the amount of blue light, melanopsin signals the brain to produce or repress melatonin production, a hormone that induces sleep. Therefore, dimming lights and avoiding devices in the evening allows melatonin to rise naturally.”

“The greater risk associated with high coffee consumption was present even when researchers statistically accounted for a variety of demographic factors such as water intake, exercise, sleep quality, stress, and body mass index.”

“Neither of the caffeine-containing beverages promoted an increase in the men's energy expenditure, and none of the men exhibited alterations in sleep quality, suggesting that they developed a tolerance to the stimulatory effects of caffeine.”

“They also collected fecal samples from the animals and identified the types and number of gut microbes present. The rats that ate the prebiotic-enriched diet resumed their normal sleep-wake cycles, core body temperature, and activity levels faster than the rats that ate the standard diet.”

“Exercise plays multiple roles: it aids in muscle building, enhances insulin sensitivity, promotes better sleep, and even manipulates the homeostat of our appetite, influencing our hunger and satiety cues.”

“Other research suggests that nutrition, exercise, sleep, and stress management may lengthen telomeres. Identifying the mechanisms that drive these correlations has proven challenging, but a few candidates stand out, including immune function and metabolic health.”

“Finally, the participants completed a sleep study to determine the effects of circadian rhythm on brown adipose tissue metabolism. Winter swimmers had a lower core body temperature and reduced uptake of glucose by brown adipose tissue at a comfortable room temperature.”

“When they ate milk chocolate in the evening, they consumed about 150 fewer calories during the rest of the day; their physical activity, heat dissipation after meals, and carbohydrate metabolism increased; and their sleep quality improved.”

“Morning light can influence alertness, mood, and circadian timing, while exercise can improve positive affect. In a small laboratory study, artificial dawn simulation supported mood and selected cognitive measures after sleep restriction.”

“An acute tracer study supports use of a larger bolus after exercise. Fourth, pre-sleep protein can support overnight synthesis. Fifth, whey and casein are practical supplements: whey digests rapidly and casein more slowly.”
