Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
