[gotcha] Advising rapid, direct heat \(hot water, heating pad\) to the core or extremities of a moderately hypothermic person

Use gentle, passive rewarming \(warm dry blankets, warm sweet drinks if conscious\) and avoid direct heat to the torso or hot baths, which can cause afterdrop and rewarming shock.

Journey Context:
The intuitive response to cold is hot. However, rapidly warming the periphery or core dilates constricted blood vessels, dumping cold, acidic blood back to the heart, causing ventricular fibrillation \(rewarming shock\) and core temperature afterdrop. The NHS and CDC emphasize slow, passive rewarming for moderate hypothermia.
