Heat exhaustion can lead to a heat stroke, and is a result of your body overheating. The causes include exposure to high temperatures, combined with high humidity and strenuous physical activity (Heat Exhaustion, 2021). This is preventative, so be mindful this summer while engaging in activities outside.
Other causes include, dehydration, alcohol use and over dressing in hot weather. If the body can not regulate the it’s internal or core temperature of 98.6 F or 37C; and continues to be exposed without intervention, it can lead to a heat stroke (Heat Exhaustion, 2021; Heat Stroke, 2021). Stay hydrated, wear light clothing and minimize your exposure to the heat if possible

Signs and symptoms of heat exhaustion include heavy sweating, fatigue, thirst, and muscle cramps, (Heat Exhaustion, 2021). Heat cramps are the first symptom of the body over heating. Heat cramps can usually be treated by drinking fluids or sports drinks containing electrolytes (Gatorade, Powerade, and pickle juice-[a favorite with bike riders]), getting into cooler temperatures, such as an air-conditioned or shaded place, and resting (Heat Exhaustion, 2021). Prompt treatment usually prevents these symptoms from progressing to a heat stroke.
A heatstroke is an emergent condition and will occur as a result of prolonged exposure to high temperature or physical exertion in the heat. This can occur if your body temperature rises to 104 F (40 C) or higher (Heat Stroke, 2021).
Just keeping you informed.
