Sleep is vital for muscle recovery and overall health, playing a key role in the body's repair processes. During deep sleep, the body releases growth hormone, which is critical for muscle repair, growth, and protein synthesis. Sleep also helps regulate hormones that control hunger and metabolism, impacting energy balance and weight management. Insufficient sleep can lead to decreased exercise performance, increased fatigue, and higher injury risks. Prioritizing quality sleep improves not only physical recovery but also mental well-being and cognitive functions.
