Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
