Heat stress is a term used to describe the stress placed onto the human body due to persistent exposure to high levels of heat. This includes all types of heat, including air temperature and humidity, exposure to radiative heat (e.g. sunlight, process/equipment heat), and internally produced heat (i.e. exertion). Exposing a person to heat stress causes their body temperature to increase, and to self-cool they will begin to sweat. The longer that a person is exposed to heat stress, the longer they will be sweating, losing fluids and salts. As this continues, the person will become dehydrated, and their body will be less able to effectively self-cool, and their body temperature will rise. Rising body temperatures, if not managed, will result in potentially serious heat-related illnesses.
