Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated.
