Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
