Hydration plays a crucial role in maintaining physical performance during exercise. Proper fluid intake helps regulate body temperature, maintain blood volume, and support cardiovascular function. Dehydration can lead to decreases in endurance, strength, and cognitive function, ultimately impairing performance. It’s recommended to drink fluids both before and during exercise, especially in hot environments or during prolonged physical activity. Consuming fluids rich in electrolytes may also enhance hydration levels and performance, making it essential to monitor fluid loss and replenish adequately.
