What is extreme heat, and why is it dangerous?
Extreme heat is typically defined as a prolonged period of heat and humidity with temperatures above 90 degrees. While an individual’s tolerance for heat can vary, in extreme heat it becomes more difficult for your body to maintain its normal temperature, which can lead to serious illness. Even if the outside temperature does not seem particularly concerning, high humidity levels can increase the feeling and impact of heat.Heat-related illness
Although heat-related illness is preventable, extreme heat is the leading cause of weather-related deaths in the United States. The elderly, young children and those with existing medical conditions are at the greatest risk of developing heat exhaustion, heat stroke, and heat cramps. Heat exhaustion happens when the body is unable to cool itself down after physical activity in a hot environment. It’s important to know the signs of heat exhaustion listed below and move to a cool place to avoid the symptoms getting worse. Heat stroke happens when your body overheats from extended exposure to heat. Heatstroke can damage major organs, including the heart, brain, and kidneys; therefore, it’s crucial to seek immediate medical attention if you experience any of the symptoms of heatstroke listed below. Heat cramps are involuntary muscles spasms likely caused by low electrolytes. Heat cramps can happen in the shoulders, calves, and thighs and can result from exercising or working in a hot environment. Because many people don’t know the true dangers of extreme heat or may not take the warning signs seriously, they may not know that they are at risk before serious symptoms start.
