A common effect of dehydration on athletic performance is reduced endurance and increased fatigue. Even mild dehydration can impair thermoregulation, leading to overheating and decreased physical output. Athletes may experience a drop in strength, focus, and coordination, which increases the risk of injury. Maintaining hydration by consuming adequate fluids before, during, and after exercise is vital for optimal performance. Symptoms like dizziness, dry mouth, and muscle cramps may indicate the need for increased fluid intake to support physical activity effectively.
