Exercise has a positive effect on sleep quality by promoting deeper and more restful sleep. Regular physical activity can help to regulate the circadian rhythm, making it easier to fall asleep and stay asleep. Exercise can also reduce symptoms of anxiety and depression, which often interfere with sleep. Engaging in moderate-intensity workouts, especially earlier in the day, can increase the total sleep duration and enhance REM sleep, crucial for cognitive function and mood regulation. Therefore, incorporating exercise into daily routines is a beneficial strategy for improving sleep quality.
