If you have been outdoors lately, you may have noticed – it’s HOT! Even though we know it’s coming, it seems like really HOT weather can come very quickly, especially here in Texas. Being outdoors in hot weather, especially when the heat is accompanied by high humidity, requires special precautions. Normally, our bodies keep themselves cool by sweating. But sometimes, sweating is not enough, and body temperature can rise to dangerous levels, causing you to develop a heat-related illness. Each year, approximately 600 people in the US die from heat-related causes.
The most common cause of heat-related illness is extended exposure to the heat. Exercising or working in the heat increases the risk of illness. Older adults, young children, and individuals who are sick or overweight are at a higher risk, and some medications and drinking alcohol can also increase risk.
What is a heat-related illness?
Heat-related illnesses include:
- Sunburn: Sunburn is something probably everyone has experienced. It begins as painful, red, and warm skin. Once the skin has been sunburned, avoid additional exposure to the sun by wearing protective clothing, take cool baths, use moisturizing lotion on affected areas, and do not break any blisters which may form. (For more information, see previous blog on sunburns.)
- Heat rash: This is generally a mild form of illness and refers to superficial skin irritation due to excessive sweating. This is most common in young children.
- Heat cramps: Usually limited to arms, legs, and/or abdomen, these cramps or muscle spasms occur during heavy exercise.
- Heat exhaustion: This form of the illness usually occurs after several days of exposure to high temperatures (with or without high humidity) and insufficient fluid intake. Symptoms include profuse sweating, rapid breathing, and a fast, but weak pulse rate. If untreated, it may develop into heat stroke.
