What is heatstroke or heat exhaustion? With the warm weather season upon us, we need to focus more on our bodies and how to stay healthy in the heat. Heatstroke is one of the greatest risks when working outdoors in the high temperatures of summer. Heatstroke can occur within 10 to 15 minutes of the body’s sweating mechanism failing and the body temperature rising.
Heat exhaustion is a less intense form of heatstroke that can occur after prolonged exposure to high temperatures over a period of time. People most prone to heat exhaustion include those that work outdoors in high temperatures. 
Signs and symptoms of heat stroke:
- High body temperature (above 103 degrees orally)
