Exercise positively impacts sleep quality by promoting deeper and more restful sleep. It helps regulate circadian rhythms, reduces anxiety, and eases muscle tension. Engaging in physical activity increases the production of endorphins, which leads to overall emotional well-being. Moreover, regular exercise can help individuals fall asleep faster and stay asleep longer. However, timing is essential; exercising too close to bedtime may disrupt sleep. Overall, incorporating consistent physical activity into one's routine can significantly enhance the quality of sleep.
