Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
