Never leave infants, children or pets in a parked car. It only takes seconds for the temperature inside a car to become life threatening to a child. In a short time, the heat can cause brain damage, coma and even death. These are painful contractions of the muscles, usually in the abdomen, arms or legs. Children with muscle cramps should rest in a cool, shady location and drink plenty of fluids.
Gentle massage can also help ease the pain.
These cramps can be the first sign of more serious heat illness, so seek medical attention if the cramps do not subside in one hour. This condition can lead to heat stroke if not treated. Children with any of these symptoms should stop activity immediately, start drinking fluids right away and sit or lie in a cool, shady location. Help cool the child down with fans, cool damp towels or ice packs. If vomiting is present or symptoms persist for more than a few minutes, seek medical attention immediately.
