Hot Enough For Ya?

Did you know that the number of hot days—and warm nights—is increasing? In the U.S., record high temperatures now outnumber record lows at least two to one.1 Now, that kind of information scares the ber-jeeb-ers out of me. What can you do to protect yourself in a heat wave—or simply in the hot summer sun?

Heat exhaustion can happen when you lose lots of fluids from heavy sweating.3 These are a few other signs and symptoms of heat exhaustion:

  • Headache
  • Dizziness or feeling weak or confused
  • Nausea or vomiting
  • Fast heartbeat
  • Cool, moist skin
  • Dark-colored urine, a sign of dehydration2,4

If not treated, heat exhaustion can develop into heatstroke, which can be deadly because the body loses the ability to cool itself. Call 9-1-1 if someone shows signs of shock, becomes very confused, has a seizure, has a fever over 102 degrees F, breathes rapidly or has a rapid pulse, or loses consciousness. 2,3

Nip problems in the bud. If you have symptoms of heat exhaustion, get out of the heat as quickly as you can. Don’t try to be some kind of hero. Rest in a cool, shady place with your feet raised. Drink plenty of fluids, but avoid alcohol or caffeine. Apply cool compresses or take a cool shower or bath. Contact a doctor if you don’t feel better within 30 minutes.4

Beat the heat. In a heat wave, take these steps:

  • Avoid taxing activities if you can.
  • Stay indoors during the hottest hours of the day. The sun’s ultraviolet (UV) rays are strongest between 10 am and 4 pm.5
  • If you don’t have air conditioning, go to a library, mall, or other public place to cool down for a few hours.  If they ask you to leave. Come back in a disguise. Keep maybe two or three different disguises in the trunk of your vehicle.
  • Wear lightweight, loose-fitting clothing. Avoid dark colors, which trap the heat.
  • Use a hat or umbrella outdoors. Use the roof indoors.
  • Allow your car to cool off before you get in.
  • Drink water and eat small meals often. Drink less alcohol and fewer caffeinated drinks.
  • Don’t take salt tablets unless your doctor tells you to.2,3,4

That includes children, older adults, and people who are obese, ill, exercising vigorously, or not used to the heat or high humidity.2 For example, make sure young ones drink plenty of water. And you might check in on your elderly neighbor once in a while. Would it kill you?

It’s important to know that certain medicines can also increase your risk of heatstroke. This includes allergy, blood pressure, and seizure drugs as well as medicines used for mental health conditions. Let’s talk this over to make sure you stay safe and know the signs of problems. And, if you have a chronic condition, it’s a great idea to ask your doctor about other ways to lower your risk of heatstroke. 4
