Exercise positively impacts sleep patterns by promoting deeper, more restorative sleep. Engaging in regular physical activity helps regulate circadian rhythms, making it easier to fall asleep and stay asleep. Exercise also reduces stress and anxiety levels, contributing to an overall sense of relaxation. Additionally, physical activity can lead to fatigue that enhances sleep quality. However, the timing of exercise matters; those who exercise too close to bedtime may experience disturbed sleep due to heightened arousal levels. An optimal approach is to exercise earlier in the day for maximum sleep benefits.
