With summer upon us, many people are turning on their electrical fans to help keep cool. Sounds simple, but it may surprise you to know that under certain conditions, an electrical fan may actually raise your body temperature, especially if you are a senior citizen.
The body tries to cool itself down by sweating, but older folks tend to sweat less. Since fans help to cool the body by increasing sweat evaporation, a person who sweats very little will not experience much relief. On top of that, fans do generate some heat simply through their mechanical movement, so it is conceivable that they may raise the temperature in a small space. In turn, this can raise the body’s core temperature and increase heart rate.
In an interview with Health Day’s Don Rauf, published on line in U.S. News and World Report, I explained the cardiac consequences by explaining that “elevated core temperatures could put excessive strain on the heart and aggravate conditions such as high blood pressure and angina [chest pain when the heart muscle is not getting enough blood].” Alternatives? “Of course, air conditioning would be the best option,” I suggested, “but short of that, applying wet compresses would likely be helpful, as would hydration with cool beverages, preferably water.”
