Extremely hot or cold environments are places where temperatures are so high or low that they can cause heat-related or cold-related illness or injury to a person. Air temperature as well as other factors can contribute to creating an extreme temperature environment. Heat-related and cold-related illnesses and injuries can be fatal.
