Rapid rises in heat gain due to exposure to hotter than average conditions compromises the body's ability to regulate temperature and can result in a cascade of illnesses, including heat cramps, heat exhaustion, heatstroke, and hyperthermia. But heat also helps the human body. When you're hot, you sweat. That makes you lose fluids and electrolytes. In addition, heat makes your blood vessels dilate to increase sweating.
