Inadequate sleep significantly impacts muscle recovery by impairing the body's ability to repair and regenerate tissues. During deep sleep, growth hormone levels peak, aiding muscle repair and growth. Sleep deprivation can lead to increased levels of cortisol, a stress hormone that can hinder recovery and promote muscle breakdown. Furthermore, insufficient rest affects performance, decision-making, and overall health. Prioritizing quality sleep is essential for athletes and fitness enthusiasts to optimize recovery, enhance performance, and maintain long-term health and wellness.
