The first step in treating a victim of heat stroke focuses on quickly lowering the victim’s core body temperature to prevent further damage to vital organs. Immersing the casualty in the coldest water available is an effective method for rapidly cooling the body. This immersion allows for maximum surface area exposure, which facilitates heat loss much more efficiently than other methods.

When dealing with heat stroke, time is of the essence, as prolonged elevated body temperature can lead to severe complications or even death. Immersion in cold water is one of the quickest ways to achieve effective cooling. Other cooling methods, like administering fluids or using ice packs, can be beneficial in supportive roles but do not lower core temperature as rapidly as full immersion. Moving the victim to a shaded area is also important as it helps to reduce further heat exposure, but it does not address the immediate need for cooling. Thus, immersing the casualty in the coldest water available is the most critical initial action when treating heat stroke.
