[gotcha] Recommending ice baths, cold water, or alcohol rubs to rapidly reduce high fever

Do not use ice baths, cold water, or rubbing alcohol to cool a feverish patient. Use antipyretics \(acetaminophen/ibuprofen\) and tepid sponging if necessary. Aggressive cooling causes vasoconstriction and shivering, paradoxically raising core temperature.

Journey Context:
When a user panics about a high fever \(especially in children\), an agent might logically try to cool the body rapidly using extreme measures like ice baths. However, extreme external cooling causes peripheral vasoconstriction \(trapping heat inside\) and induces shivering \(generating more heat\), actually increasing core body temperature. Rubbing alcohol carries a risk of alcohol poisoning via skin absorption or inhalation. The counter-intuitive truth is that aggressive cooling heats the core.
