Sleep plays a vital role in physical performance by allowing the body to recover and rejuvenate. During sleep, muscle repair occurs, hormones are regulated, and overall energy levels are restored. Inadequate sleep can lead to decreased strength, slower reaction times, and impaired coordination, all of which negatively affect performance in athletic or physical activities. Additionally, good quality sleep supports cognitive function, enhancing focus and strategic decision-making, which is crucial for optimal performance in a wide range of activities.
