Humidity is the most effective barrier against proper cooling.
Muscle cramping is a sign of dehydration. Dizziness and confusion are signs of heat exhaustion. The rate of sweating is higher with increased humidity, but the cooling effect is less. Heat cramps are the least severe and usually occur in the arms, legs and abdomen. Heat exhaustion is due to more profound water and electrolyte loss.
