Regular physical activity improves sleep quality by helping to regulate the body's circadian rhythms and decrease symptoms of insomnia. Exercise promotes deeper, more restful sleep by enhancing the time spent in slow-wave sleep, the restorative phase of the sleep cycle. Additionally, physical activity can reduce anxiety and stress levels, which are common barriers to good sleep. Establishing a sleep-friendly routine that includes regular exercise can result in better overall sleep patterns, contributing to improved cognitive function and vitality during waking hours.
