Exercise positively affects sleep quality by helping regulate your circadian rhythm and promoting deeper sleep. Physical activity increases the duration of slow-wave sleep, which is essential for physical restoration and recovery. Engaging in regular exercise can alleviate symptoms of insomnia and reduce anxiety, contributing to improved sleep patterns. However, timing is essential; exercising too close to bedtime might disrupt sleep for some individuals. Overall, incorporating exercise into a daily routine can significantly enhance sleep quality, leading to better overall health and well-being.
