Hydration significantly impacts ***athletic performance*** in hot weather by regulating body temperature and maintaining optimal fluid balance. In hot conditions, athletes tend to sweat more, increasing the risk of dehydration, which can impair performance and lead to heat-related illnesses. Proper hydration before, during, and after exercise helps to sustain energy levels, improve endurance, and maintain cognitive function. Aim for hydration strategies tailored to individual needs, such as electrolyte-rich drinks, to replace lost fluids and maintain optimal physical output during workouts in the heat.
