Exercise contributes to improved sleep quality by regulating circadian rhythms and reducing stress through the release of endorphins. Physical activity increases the amount of deep sleep experienced and may also help alleviate sleep disorders such as insomnia. Moreover, exercising during the day, especially in the sunlight, can enhance the body’s ability to fall asleep and stay asleep at night. Regular workouts improve overall sleep duration and efficiency, fostering recovery and better mental performance, ultimately leading to a positive feedback loop of better fitness and sleep.
