Regular exercise can significantly enhance sleep quality by promoting deeper sleep and reducing the time it takes to fall asleep. Engaging in regular physical activity helps regulate the circadian rhythm and can alleviate anxiety or stress, which are common barriers to restful sleep. Additionally, exercising earlier in the day can lead to better sleep at night, as it increases core body temperature, followed by a natural drop that signals the body that it's time to sleep. Overall, the benefits of exercise extend beyond the day, improving overall sleep patterns and promoting satisfaction with sleep.
