Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
