Too much sun and heat can cause illness. There are three types of heat-related illness heat cramps, heat exhaustion, and heat stroke. Heat cramps usually affect people who sweat a lot during activity. Sweating pulls salt and water from the body. A low level of salt in the muscles causes them to cramp.
Cramps usually affect muscles in the abdomen, arms, or legs and usually occur after heavy activity.
Drink clear liquids or sport beverages. Prepare to seek medical attention if cramps do not go away in one hour. Heat exhaustion is also caused by loss of salt and water contained in sweat. Elderly people, people with high blood pressure, and people who are working out in a hot environment are most prone to this condition. Loosen or remove clothing.
