how can participation in physical activity lead to improved sleep patterns?

Answer:

Physical activity can improve sleep patterns in several ways. It can increase body - temperature temporarily, and when the temperature drops later, it signals the body to sleep. Also, it reduces stress and anxiety levels by releasing endorphins, which are natural mood - boosters. Additionally, regular physical activity helps regulate the body's internal clock (circadian rhythm), making it easier to fall asleep and stay asleep.

Brief Explanations:

Consider body - temperature changes, endorphin release, and circadian rhythm regulation.
