Heat Illness


When the body is unable to cool off by sweating, heat-induced illnesses such as heat exhaustion and heat stroke can occur. These illnesses are very serious and can sometimes result in death.

High temperatures, humidity, direct sun or heat, limited air movement, physical exertion, poor physical condition, some medications, and inadequate tolerance for hot workplaces or areas can all contribute to heat stress.
