Dehydration can severely impair physical performance, affecting endurance, strength, and cognitive function. Even mild dehydration can lead to reduced athletic performance, resulting in fatigue and decreased motivation. Loss of fluids can impact thermoregulation, increasing the risk of heat-related illnesses during exercise. Additionally, dehydration can hinder recovery time and muscle performance post-exercise, increasing the likelihood of injury. Staying properly hydrated before, during, and after physical activity is crucial for maintaining optimal performance levels and overall health.
