Are you prepared to handle the heat this summer? The Centers for Disease Control (CDC) defines extreme heat as summertime temperatures that are much hotter and humid than average. As a result, heat-related illnesses occur. Stay safe this summer by knowing how to prevent, recognize and cope with heat-related illnesses.1

What is Heat-Related Illness?

Heat-related illnesses happen when a person’s body temperature rises faster than it can cool itself down.1 Certain factors may increase your risk of developing a heat-related illness:1

  1. High levels of humidity

  2. Obesity

  3. Prescription drug use

  4. Dehydration

  5. Poor circulation

Heat-Related Illnesses

Heat-related illnesses are preventable. Know the signs and symptoms to protect you or a loved one:

  1. Heat Stroke: This is the most serious heat-related illness. When it occurs, the body temperature can rise to 105°F or higher within 10 to 15 minutes.2

  2. What to look for: Body temperature of 103°F or higher, hot or damp skin, nausea, confusion and passing out.1

  3. What to do: Call 911 immediately, do not give the person anything to drink, help lower body temperature with a cool bath or cloths.1

  4. Heat Exhaustion: This happens after the body loses an excessive amount of water and salt, typically through excessive sweating.2

  5. What to look for: Cold and pale skin, weak pulse, muscle cramps, dizziness, headache and weakness.1

  6. What to do: Move to a cool place, loosen your clothes, sip water. Get medical help if you are throwing up or your symptoms last longer than an hour.1

  7. Heat Cramps: Heat cramps are caused by sweating that depletes the body’s salt and moisture levels.2

  8. What to look for: Muscle spasms, muscle pain and heavy sweating during intense exercise.1

  9. What to do: Stop any physical activity and drink water. Seek medical help if cramps last longer than an hour or if you have heart problems.2

  10. Heat Rash: Heat rash is a skin irritation from excessive sweating during hot weather.1

  11. What to look for: Red clusters of small blisters on the skin.1

  12. What to do: Stay in a cool, dry place and use baby powder to soothe the rash.1
