When caring for a guest who is overheated, what is the first action you should take?

When caring for a guest who is overheated, the initial step should be to have the guest stop any tiring activity. This action is crucial because continuing physical exertion can further raise the body temperature and exacerbate the symptoms of overheating. Allowing the guest to rest helps to prevent any potential heat-related illnesses, such as heat exhaustion or heatstroke, which can occur if the body struggles to cool down while under physical stress.

Taking a guest's temperature, providing food, or offering a blanket may be valid responses to address certain aspects of a heat-related issue, but they do not serve as the immediate and appropriate response to halt the progression of overheating. Encouraging rest is the most direct method to begin cooling the body and ensuring the guest's safety. By stopping strenuous activity, the body can start recuperating, and further interventions can be assessed based on how the guest responds to rest.
