[gotcha] Should I rub a hypothermic person's limbs or put them in a hot bath?

Warm the core first \(trunk, armpits, groin\) using warm blankets. Do not rub extremities or use direct heat like hot water.

Journey Context:
Rubbing damages frozen skin. Rapid external rewarming of limbs causes peripheral vasodilation, sending cold, acidic blood back to the heart, triggering ventricular fibrillation \(afterdrop\). Core rewarming is essential to avoid fatal cardiac arrhythmias.
