Heat Wave Survival Tips
Feeling the heat? A heatwave stretching across much of the U.S. has many of us seeking relief, but it’s prime time for heat-related illness to strike.
In recent years, excessive heat has caused more deaths than all other weather events, including floods, according to the American Red Cross. Our bodies lose water and salt when we perspire, which can lead to heat cramps. If not addressed, dehydration can lead to heat exhaustion. Heat exhaustion leads to heatstroke, a potentially life-threatening condition.
Young children, the elderly, and people with chronic diseases are most at risk of developing heat cramps, heat exhaustion, or heatstroke. Do you know how to lower your risk of heat-related illness…would you recognize the warning signs, and would you know what to do should heat-related illness strike?
Tips to Avoid Heat-Related Illness
- Wear lightweight, loose-fitting clothing made of breathable fabric like cotton.
- When outdoors, wear a wide-brimmed hat.
- Choose shade over the sun on a hot day.
- Avoid strenuous exercise during a heatwave.
- Drink plenty of water or other fluids.
- If you feel overheated, take a cool shower or bath.
- Avoid sitting in a hot car or leaving your child in the car. (And that goes for pets, too!)
- Take advantage of cooling centers during a prolonged hot spell.
- Listen to weather advisories before planning outdoor events.
- Check on people who live alone, especially the elderly or ill.
