Hydration strategies are crucial for improving athletic performance in hot weather by regulating body temperature and maintaining electrolyte balance. During intense exercise, especially in heat, the body loses fluids through sweat, increasing the risk of dehydration and negatively impacting performance. Proper pre-exercise hydration helps optimize bodily functions, while consuming fluids during and after exercise replenishes lost electrolytes. Additionally, using isotonic beverages can provide quick energy alongside hydration. By incorporating effective hydration strategies, athletes can ensure endurance, improve cognitive function, and perform at their peak in challenging conditions.
