Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating.
