Heat-related illnesses can be serious and, in some cases, even deadly. Because of this, it’s important to be mindful of potential warning signs and symptoms of heat-related illness and be able to recognize them when they arise. In the United States, an average of 702 heat-related deaths occur each year, and 9,000 people are hospitalized each year due to heat.
With summer weather around the corner, it’s important to be aware of the warning signs and symptoms so you can take appropriate action if needed. This blog post will discuss the warning signs and symptoms of heat-related illnesses and provide an overview of what actions to take should any of these indications appear.
What is a heat-related illness?
Heat-related illnesses result from prolonged exposure to high temperatures, humidity, or both. When the body is exposed to extreme heat, it works hard to keep itself cool, which can lead to dehydration, heat exhaustion, heat stroke, and other heat-related illnesses.
A study from the Environmental Protection Agency shows the number of “heat-related” deaths that occur each year in the fifty states plus the District of Columbia. The orange line illustrates how many deaths list heat as the primary factor behind the death. The blue line represents deaths in which heat is either the primary or a contributing factor between May and September.
It is important to take steps to protect yourself from heat-related illnesses. Drink plenty of water to stay hydrated, take frequent breaks in the shade or air-conditioned areas, and wear loose, light-colored clothing to help keep your body temperature regulated. Be aware of warning signs, such as headaches, dizziness, and nausea, that could indicate an oncoming heat-related illness. As these illnesses can be life-threatening if not treated quickly, talk to your urgent care specialist if you have any concerns.
What are the signs and symptoms of heat-related illnesses?
Heat-related illnesses can range from mild to severe and range anywhere from heat cramps to heat stroke. Knowing the signs and symptoms of each type of heat-related illness is the best way to ensure your and your family’s safety while enjoying the outdoors.
