Sleep plays a critical role in muscle recovery after workouts by promoting tissue repair and growth hormone secretion. During deep sleep, the body engages in the process of muscle restoration, replenishing energy stores and reducing muscle soreness. Adequate sleep supports proper immune function, allowing the body to recover from stressors placed on it during exercise. Insufficient sleep, on the other hand, can hinder performance, increase fatigue, and even lead to injury risks. Prioritizing quality sleep is key to achieving optimal fitness results and long-term well-being.
