NIH warns of increased risk of heat-related illness for seniors

(HealthDay)—Older adults are at significantly increased risk of heat-related illnesses, which can include heat stroke, heat edema, heat syncope, heat cramps, and heat exhaustion, according to the National Institutes of Health.

Factors that could increase risk include age-related changes to the skin such as poor blood circulation and inefficient sweat glands; heart, lung, and kidney diseases as well as other illnesses; high blood pressure and other conditions necessitating a change in diet; reduced sweating, caused by medications such as diuretics, sedatives, and tranquilizers; polypharmacy; being very overweight or underweight; drinking alcoholic beverages; and being dehydrated. Risk can also be increased in association with lifestyle factors.

On particularly hot and humid days, older people, especially those at increased risk, should stay indoors, particularly if there is an air pollution alert in effect. Plenty of fluids should be drunk and light-colored, loose-fitting clothes should be worn. Homes should be kept cool or people should go somewhere cool.
