A circadian rhythm is a natural process trusted Source that takes place every day. In humans, circadian rhythms are the approximate 24-hour patterns the body and brain go through, allowing for changes in the body’s physical and mental states and mood and behavioral changes.
Sleep and circadian rhythms are fundamental phenomena in biological organisms. Research indicates that lack of sleep and disruptions in circadian rhythms correlate with poor mental and physical health. In modern society, humans live surrounded by various factors that disrupt our sleep and circadian rhythms, such as the internationalization of business, the increasing 24-hour nature of commercial services, the ease of accessibility of information, longer and more unsocial working hours
When properly aligned, a circadian rhythm can promote consistent and restorative sleep. But when this circadian rhythm is thrown off, it can create significant sleeping problems, including insomnia.
Exercise is a strong entrainment signal for the mammalian circadian clock. Proper exercise can have a significant circadian phase-shifting effect and affect the sleep and wake schedule in humans. Disruption of the circadian rhythm also has significant influences on the exercise function.
The strong links between circadian rhythm and exercise play important roles in the heart.
Making smart food choices is the key to eating and living healthy. But now, the latest research shows that when we eat is just as important as what we eat.
Since the circadian system is signaled, in part, by dietary intake, eating at consistent times is important for robust circadian rhythms. Thus, dramatically changing our mealtime from day to day may compromise physiology, similar to how sleep patterns are disturbed after an abrupt change in time zone (i.e., jet lag)
Restricting your eating to a 12 to 15-hour window during the day can be helpful. Eating before bed can also have a negative impact on sleep, so its best to avoid eating late in the evening. At the very least, try timing your last meal so that it a minimum of three hours before you go to bed.
