Regular physical activity markedly improves sleep quality by aiding in the regulation of sleep patterns and decreasing symptoms of insomnia. Engaging in exercise increases energy expenditure, which can lead to more restorative sleep cycles. Physical activity also helps in reducing anxiety and stress, factors that often interfere with sleep. Additionally, post-exercise, the body experiences a drop in temperature, which can promote sleepiness. Establishing a routine of regular exercise can significantly enhance overall sleep quality and duration.
