Summer is not all fun. Too much sun and heat can be dangerous. Heat exhaustion occurs when there is too much sun or heat exposure, causing the body to get too hot. When this happens the body's heat regulating mechanism no longer works properly. There is a loss of fluids or dehydration from the body. Symptoms of heat exhaustion include weakness, profuse sweating, dizziness, muscle cramps, nausea, loss of appetite, fatigue, headache and even fainting. Treatment includes the replacement of lost salt and water to the body by giving the person cool water and special electrolyte replenishing fluids. Also, every attempt should be made to lower the body's temperature. Move the person to a cool place, the shade or preferably, somewhere air conditioned. Cool the body down with tepid water or ice packs in the armpits, neck and groin.

Heat stroke is more serious. When the body temperature rises to 103-104 degrees and the person is red and hot and is not sweating, this is an emergency situation. Other symptoms include all of the above symptoms for heat exhaustion, except the person can no longer sweat. That is where the danger lies. The emergency medical system should be activated. The person could become unconscious or even die if their body temperature is not brought down. Move them to a cool place, preferably air conditioning. Cool down the body with tepid water, starting from the head. Ice packs may be placed in the armpits, groin area and on the neck. Sips of cool water and electrolyte replenishing fluids should be given if the person is conscious and not nauseated.

Never give sodas or drinks with high sugar content, as these work to increase dehydration.In general, all persons working outside or in hot areas, should drink adequate amounts of water and electrolyte replenishing fluids. Take frequent rest periods out of the sun, and never work in enclosed places without air conditioning.
