Extreme heat occurs when temperatures exceed 90 degrees, and in Kansas, humidity adds to the health risks associated with such high temperatures. In fact, extreme heat is the leading cause of death among all weather-related disasters. So, it’s important to understand how high temperatures affect us and how to protect ourselves in extreme heat.
Jeff Goodell, environmental author, describes two types of stress caused by the heat. The first is called classic heat stress, and it’s the typical heat exhaustion most of us are familiar with. High temperatures affect small children, seniors, and those with chronic conditions the most. This type of heat stress can cascade into heat stroke and eventually death if left untreated.
Exertional heat exhaustion is another type of heat stress that can put even the most fit, young, and vibrant people in danger. The body aims to maintain homeostasis including an internal temperature around 98.6 degrees. When physical labor raises the core temperature, the body must compensate by sweating and increasing blood flow to the skin. However, extreme heat can make it even more challenging to cool down. Symptoms of exertional heat exhaustion can include low blood pressure, hyperventilation, altered mental status, vomiting, and seizures. Once again, if symptoms are not addressed, death can result. Those who work outdoors such as construction workers, farmers, and athletes are at a high risk for exertional heat exhaustion.
Now that summer has officially arrived and temperatures are reaching triple digits, here are a few tips from the American Red Cross Association concerning extreme heat:
First, learn how to stay hydrated. An average person should drink about 3/4 of a gallon of water daily, but everyone’s needs vary. Avoid sugary, caffeinated, and alcoholic drinks that dehydrate the body. Also, if you sweat a lot, consider having a snack or a sports drink throughout the day to replenish electrolytes.
Next, make a plan. Brainstorm places you can go to cool down in case of a power outage. If you have air conditioning, replace filters and perform regular maintenance to ensure it’s working properly. Another way to avoid overheating is to wear lightweight, loose clothing. Also, be sure to check in with loved ones who are at high risk for heat exhaustion.
Finally, be prepared for the worst. You may not be able to prevent heat illness in others, so it’s imperative to recognize the signs. These can include excessive sweating, pale skin, altered mental status, and increased respiration. In severe cases, knowing CPR may be necessary. So, brush up on your First Aid skills or get trained.
As temperatures continue to rise, keep these tips in mind. Create a plan to respond to the heat and take care of yourself and your loved ones. Most of all, stay cool!
