Our bodies are designed to work hard to maintain an even internal temperature. Heat stroke is serious business, so knowing how to prevent it, the warning signs of it occurring, and what to do about heat exhaustion and heat stroke can be lifesaving. The simple, common sense answer of course is “stay cool and hydrated.” Sounds easy enough – but it is more complicated than that.
Understand your risk level. Healthy people can be adversely affected by heatwaves, as can those who are very young and those 60 and better. Some medications and some long-term health conditions such as heart disease, diabetes, and dementia can lead to greater risk. As the body heats up, blood vessels close to the skin open to transfer heat back to the environment – this makes the heart work harder. Sweating takes place for the same reason. In our dry climate, many people do not realize they are becoming dehydrated because the sweat evaporates immediately. For those not acclimated to high altitude, symptoms from heat are exacerbated and may be hard to distinguish from altitude sickness. Residences may remain quite warm at night if they heat up during the day. When it fails to cool down sufficiently at night, this places greater stress on the body. Even during rest, at 85 degrees, the body can lose nearly a half-gallon of water overnight. Prevention tips.
Signs of heat exhaustion and heat stroke.
