Temperature impacts hydration needs during exercise significantly, as exercising in warmer conditions leads to increased sweat production and fluid loss. Higher temperatures elevate body temperature, prompting the body to cool itself through perspiration. This process can result in significant dehydration if fluid intake is not adjusted accordingly. Therefore, it is crucial for individuals exercising in hot conditions to increase their fluid consumption before, during, and after workouts to maintain hydration status, support performance, and avoid heat-related illnesses. Proper hydration is essential for optimal exercise performance in varying temperatures.
