Risk Factors for Heat Exhaustion
In addition to athletes, there are a few other factors that increase the risk of heat exhaustion:
- Age - Young children and adults over age 65 are often unable to adjust to changes in temperature as quickly as older children and adults, making them vulnerable to heat exhaustion.
- Medications - Some types of medications such as Diuretics, sedatives, tranquilizers, stimulants, heart, and blood pressure medications and medications for psychiatric conditions pose an increased risk for heat exhaustion.
- Health conditions - Individuals with certain medical conditions such as heart, lung, or kidney disease, obesity or underweight, high blood pressure, diabetes, mental illness, sickle cell trait, alcoholism, or sunburn are also at increased risk.
How to Treat Heat Exhaustion
If heat cramps lead to heat exhaustion:
- Rest in a cooler location.
- Drink cool fluids.
- Apply cool water to the skin.
- Rest with legs elevated above heart level.
