As the mercury in your outdoor thermometers rises to triple digit levels, it is important to maintain a healthy body temperature. People with chronic disease and those taking medications, such as immunosuppressive drugs, need to be especially careful. As more than 1,200 immune-suppressed athletes train for the 2010 National Kidney Foundation U.S. Transplant Games, NKF's fitness expert Chris L. Wells, PhD, offers 10 ways to avoid heat illnesses this summer.
The signs and symptoms of heat cramps include discomfort in the muscles that often leads to a decrease in performance. These are caused by either too little or too much fluid intake, which leads to a decrease in the body's sodium level.
Heat exhaustion is marked by dehydration, dizziness, gastrointestinal distress, persistent muscle cramps, cool clammy skin, chills, weakness, a change in mental status and hyperventilation.
Heat stroke is the most serious of the three and is considered a medical emergency. Signs and symptoms are similar to exhaustion but also include marked changes in mental status (delirium, hysteria or a loss of consciousness), a rapid heart rate, low blood pressure and a body temperature elevated above 104Â° F.
