Why are older adults more prone to heat stress?

  • Older adults do not adjust as well as young people to sudden changes in temperature.

  • They are more likely to have a chronic medical condition that changes normal body responses to heat.

  • They are more likely to take prescription medicines that affect the body’s ability to control its temperature or sweat.

Stay cool, stay hydrated

  • Stay in air-conditioned buildings as much as possible. If your home doesn’t have air conditioning, contact your local health department or locate an air-conditioned shelter in your area.

  • Do not rely on a fan as your main cooling source when it’s really hot outside.

  • Drink more water than usual and don’t wait until you’re thirsty to drink.

  • If your doctor limits the amount of fluids you drink or has you on water pills, ask them how much you should drink during hot weather.


  • Don’t use the stove or oven to cook—it will make you and your house hotter.

  • Wear loose, lightweight, light-colored clothing.

  • Take cool showers or baths to cool down.

  • Do not engage in very strenuous activities and get plenty of rest.

  • Check on a friend or neighbor and have someone do the same for you.

Stay informed

  • Check the local news for health and safety updates.

  • Seek medical care immediately if you have, or someone you know has, symptoms of heat-related illness like muscle cramps, headaches, nausea or vomiting.
