Most people who die from hyperthermia each year are over 50 years old. Health problems that put you at greater risk include:
* Heart or blood vessel problems, poorly working sweat glands, or changes in your skin caused by normal aging.
* Heart, lung, or kidney disease, as well as any illness that makes you feel weak all over or results in a fever.
* Conditions treated by drugs such as diuretics, sedatives, tranquilizers, and some heart and high blood pressure medicines. These may make it harder for your body to cool itself by sweating.
* Taking several prescription drugs. Keep taking your medicine, but ask your doctor what to do if the drugs you take make you more likely to become overheated.
* Being very overweight or underweight.
* Drinking alcoholic beverages.
