Hydration is critical before, during, and after exercise to maintain optimal physiological function and performance. Proper hydration ensures adequate blood circulation, temperature regulation, and nutrient transport to muscles. Dehydration can lead to fatigue, reduced performance, and increased risk of heat-related illnesses. Drinking water before exercising prepares the body, while continuous hydration during activity helps sustain energy levels. Post-exercise hydration aids in recovery by replenishing lost fluids and electrolytes. Consequently, prioritizing hydration is essential for enhancing endurance, physical performance, and overall health.
