Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.

Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
