Which treatment is NOT recommended for heat exhaustion?

The application of ice packs is not recommended for treating heat exhaustion primarily because it can lead to a rapid cooling effect that may cause the body's temperature regulation to respond adversely. Heat exhaustion involves dehydration and an electrolyte imbalance due to prolonged exposure to high temperatures, and while cooling the body is important, it's essential to do so in a controlled manner.

Removing the individual from the heat allows the body to begin cooling naturally, and IV fluids as well as fluid replacement are critical components of treatment that help to restore hydration and electrolyte balance. Ice packs, on the other hand, can cause constriction of blood vessels and potentially lead to further issues such as shock or hypothermia if used excessively or improperly. Therefore, while cooling is necessary, the method of application needs to be judicious, making ice packs less preferable in this context.
