Heat-related illnesses, like heat exhaustion or heat stroke, happen when the body is not able to properly cool itself. While the body normally cools itself by sweating, during extreme heat, this might not be enough. In these cases, a person’s body temperature rises faster than it can cool itself down. This can cause damage to the brain and other vital organs.
Older adults, the very young, and people with mental illness and chronic diseases are at highest risk. However, even young and healthy people can be affected if they participate in strenuous physical activities during hot weather.
Summertime activity, whether on the playing field or the construction site, must be balanced with actions that help the body cool itself to prevent heat-related illness. Use this website to learn more on how to stay safe in the heat this summer, including how to prevent, recognize, and cope with heat-related illness.
