The Phoenix Fire Department does not recommend the use of table salt or salt tablets to replace body electrolytes. Many electrolyte replacement drinks are available on the market. Electrolytes are crucial for the proper functioning of the body. They usually begin in the arms, legs or abdomen, and often precede heat exhaustion. Treatment for heat cramps is to rest in the shade, get near a fan, spray the person with water and massage the cramp.
Heat exhaustion is a medical emergency.
When a person is suffering from heat exhaustion, they will perspire profusely and most likely will be pale. It is best treated by taking the patient to a cool place, applying cool compresses, elevating the feet and giving the patient fluids. Heat stroke is the worst heat-related injury. The brain has lost its ability to regulate body temperature. The patient will be hot, reddish and warm to the touch.
