Hot days can seriously affect seniors' health

"Is it hot enough for you?"

That comment might deserve an eye roll, but you might consider tweaking it to, "Is it too hot for you today?" With daytime temperatures in the 90s during mid- to late summer and the heat index even higher on many days, hot days can indeed be too hot.

Heat can make everyone uncomfortable, but for older adults, that discomfort can also mean danger. According to the Centers for Disease Control and Prevention, older adults are more prone to heat stress for at least three reasons. One, as we age, we don't adjust as well as young people to sudden changes in temperature. Seniors also are more likely to take prescription medicines that affect the body's ability to control sweat or the body's temperature. And seniors are more likely to have a chronic medical condition that affects body response to heat.

How to stay cool when it's hot out there

First of all, make sure you have access to air conditioning. Don't rely on a fan to do the job. "If your home doesn't have air conditioning, contact your local health department or locate an air-conditioned shelter in your area," the CDC advises.Drink more water than you usually do; don't worry about the bathroom consequences. And don't wait until you're thirsty; just make sure you stay hydrated. If your doctor doesn't want you drinking past a certain limit on water or you're taking water pills, check with your doctor on how much water you should drink during hot weather.Avoid using the oven or stove-top if you can. Instead, opt for refrigerated salads or other cold foods, or foods you can microwave. Similarly, avoid using your dryer in the heat of the day.Limit activity on hot days. If you must get outdoor exercise, go for a short walk early in the morning.Wear light-colored or loose-fitting clothing to help keep cool.Cool baths or showers can help.
