Heat stress happens when your body is no longer able to control its internal temperature. Heat stress can lead to heat exhaustion and heat stroke. The symptoms of heat exhaustion include dizziness, headache, rapid pulse, nausea, and vomiting. The symptoms of heat stroke include high body temperature, confusion, and convulsions. Heat stroke can be fatal.

You can prevent heat stress when you are working in a hot environment by drinking water frequently (even if you are not thirsty), resting in the shade when you need to cool down, and wearing a hat and light-colored clothing.
