Physical activity positively affects sleep patterns by promoting better sleep quality and duration. Engaging in regular exercise can help regulate the body's internal circadian rhythms, making it easier to fall asleep and stay asleep. Exercise also reduces anxiety, stress, and symptoms of depression, which can interfere with sleep. However, the timing of physical activity matters; moderate exercise earlier in the day can be particularly beneficial for sleep, while vigorous workouts right before bedtime may be stimulating and disrupt sleep patterns. Overall, incorporating regular physical activity can lead to a more restful night’s sleep.
