What is the primary objective of first aid for heat-related illnesses?

The primary objective of first aid for heat-related illnesses is to cool the person down. Heat-related illnesses, such as heat exhaustion and heat stroke, occur when the body becomes unable to regulate its temperature, leading to potential severe health complications. Rapid cooling is crucial to prevent further progression of the illness, which can cause organ damage or even be life-threatening.

Methods to cool the person down may include moving them to a shaded or air-conditioned area, removing excess clothing, applying cool water or ice packs to key areas of the body (like armpits, neck, and groin), and encouraging the person to drink cool fluids if they are conscious and able. This cooling process helps restore the body’s normal temperature and regain physiological balance.

While providing food and hydration is important for recovery, especially since dehydration can contribute to heat-related illnesses, the immediate priority is to reduce the person's elevated body temperature to ensure safety and prevent serious complications.
