Heat Exhaustion

Heat exhaustion is the body's response to an excessive loss of water and salt contained in sweat. Those most prone to heat exhaustion are elderly people, people with high blood preset and people working or exercising in a hot environment.

Recognizing Heat Exhaustion

nausea or vomiting
The skin may be cool and moist. The victim's pulse rate will be fast and weak, and breathing will be fast and shallow. If heat exhaustion is untreated, it may progress to heat stroke. Seek medical attention immediately if:

Otherwise, help the victim to cool off, and seek medical attention if symptoms worsen or last longer than 1 hour.
