Heat kills by pushing the human body beyond its limits. In extreme heat and high humidity,
evaporation is slowed and the body must work extra hard to maintain a normal temperature.
Most heat disorders occur because the victim has been overexposed to heat or has over-
exercised for his or her age and physical condition. Older adults, young children, and those
who are sick or overweight are more likely to succumb to extreme heat.
• Stay indoors as much as possible and limit exposure to the sun.
• Stay on the lowest floor out of the sunshine if air conditioning is not available.
• Consider spending the warmest part of the day in public buildings such as libraries,
schools, movie theaters, shopping malls, and other community facilities. Circulating
air can cool the body by increasing the perspiration rate of evaporation.
• Eat well-balanced, light, and regular meals. Avoid using salt tablets unless directed to do
so by a physician.
• Drink plenty of water. Persons who have epilepsy or heart, kidney, or liver disease; are
on fluid-restricted diets; or have a problem with fluid retention should consult a doctor
before increasing liquid intake.
