Heat stroke is the most serious form of heat injury. It is a type of severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F) and confusion. Other symptoms include red, dry or damp skin, headache, and dizziness. Heat stroke occurs because of high external temperatures or physical exertion.
The hallmark symptom of heat stroke is a core body temperature above 104 degrees Fahrenheit. But fainting may be the first sign.
Dizziness and lightheadedness.
Lack of sweating despite the heat.
Red, hot, and dry skin
Muscle weakness or cramps
Nausea and vomiting
Preventing Heat Stroke:
- Wear lightweight, light-colored, loose-fitting clothing, and a wide-brimmed hat.
- Use a sunscreen with a sun protection factor (SPF) of 30 or more.
- Drink extra fluids to prevent dehydration
- Reschedule or cancel outdoor activity. If possible, shift your time outdoors to the coolest times of the day, either early morning or after sunset.
