The role of sleep in muscle repair is critical as it is during sleep that the body enters recovery mode, promoting muscle growth and repair. Sleep enhances the release of vital hormones like testosterone and growth hormone, which are essential for muscle recovery and development. Adequate sleep also aids in the replenishment of energy stores and reduces inflammation. Poor sleep can hinder recovery, leading to decreased athletic performance and increased risk of injuries. Thus, prioritizing quality sleep is essential for anyone engaged in regular physical activity or resistance training.
