So that hot weather doesn't mean hard for a worker... Working in the heat, especially outdoors, can have an impact on your health. The most serious heat-related illness is heat stroke, which can quickly lead to death. It can come on suddenly when the body becomes unable to cool itself and the body’s core temperature rises to 40 oC or higher. It’s important to know the warning signs in order to react appropriately, when necessary. Exposure to the sun’s ultraviolet (UV) rays has both short-term (sunburn, rash, eye damage) and long-term effects (skin aging, skin cancer and eye diseases). Protecting yourself from the sun, even when its cloudy, is very important. |  |
