Sleep is vital for overall health and fitness as it plays a critical role in recovery, hormonal balance, and mental focus. Adequate sleep enhances muscle repair, optimizes metabolism, and improves athletic performance. During sleep, the body undergoes important restorative processes that help regulate stress hormones and support immune function. Insufficient sleep can lead to decreased motivation, impaired judgment, and increased risk of injury, all of which can hinder long-term fitness goals. Prioritizing quality rest is essential for maintaining a healthy and active lifestyle.
