Sleep hygiene directly influences fitness performance by affecting energy levels, focus, and recovery. Quality sleep is essential for reducing fatigue, enhancing concentration, and improving decision-making during workouts or competitions. Poor sleep can lead to diminished physical performance and increased susceptibility to injuries due to slower reaction times and impaired coordination. By fostering good sleep practices, such as maintaining consistent sleep schedules and optimizing the sleep environment, individuals can enhance their athletic performance and overall physical capabilities, leading to better training results.
