End-of-day physical activity can significantly improve sleep patterns by promoting relaxation and reducing stress. Engaging in exercise releases endorphins, which can create a sense of well-being, paving the way for a smoother transition to sleep. Furthermore, physical activity helps to regulate the body's circadian rhythm, making it easier to fall asleep and stay asleep through the night. By expending energy, individuals may find that they sleep more soundly and wake up feeling refreshed, enhancing overall sleep quality.
