Physical activity can improve sleep quality by promoting more efficient sleep patterns and reducing the time it takes to fall asleep. Regular exercise can help regulate the body's internal clock and enhance the duration of deep sleep, which is crucial for restorative processes. Engaging in physical activity also reduces symptoms of anxiety and stress, which can disrupt sleep. Moreover, exercising earlier in the day is generally more effective than late-day workouts for improved sleep outcomes, underscoring the interconnectedness of activity and sleep health.
