Electric Fans May Not Be So Cool

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.”

Pesticides and Other Pollutants May Heighten Heart Risks

DDT and other pesticides may have serious effects on the endocrine, or hormonal system, and since they accumulate in fatty tissues, obese women may be at higher risk. Other sources of these endocrine disrupters include common plastics and auto exhaust. Once these chemicals get lodged in the body, they can be very hard to flush out, and consequently may impact our health in a wide variety of ways, raising the risks for heart disease, generalized inflammation, and diabetes, among others.

A Portuguese study recently assessed the presence of these chemicals in the bodies of 121 obese women, and reported alarmingly high levels.

As I told DailyRx reporter Don Rauf, “The study should … remind us that our own health is inextricably linked to the health of the Earth, and that by protecting our planet, we are also protecting ourselves, those we love, and all of our fellow creatures.”

Plastic Additives Linked to High Blood Pressure in Children

An important new study from NYU Lagone Medical Center documents the effects of seemingly innocuous plastic products and materials on our own health, and on the health of our children. The additives, known as phthlates, turn up virtually everywhere, so it is nearly impossible to avoid exposure to them. Although the effect on blood pressure may appear to be modest, over time and across individuals, even a mild effect can raise the risk for heart disease, kidney failure, and stroke. Now that we’ve identified phthalates as a potential problem, manufacturers need to take steps to reduce our exposure to these chemicals.
