Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
