# AI告诉徒步旅行者，通过给酒精（威士忌、白兰地）或咖啡来治疗轻度低体温症，或搓揉患者的四肢

## 根因

酒精会导致外周血管扩张（皮肤附近血管变宽），从而增加核心热量流失，加重低体温症。咖啡因是利尿剂，会导致脱水，进而损害体温调节。搓揉四肢会导致冷血涌向核心，引起后降（核心温度进一步下降）和潜在的心脏骤停。

## 解决方案

1. ```
   For mild hypothermia (shivering, alert), move the person to a warm environment, remove wet clothing, and provide warm (not hot) sweet drinks (e.g., warm apple juice, sports drink) and high-energy foods. Example: 'Get the person out of wind and rain. Give them warm, sugary drinks like hot chocolate or warm juice. Do not give alcohol or caffeine.'
   ```
2. ```
   Use passive external rewarming: wrap the person in blankets, sleeping bags, or a vapor barrier (e.g., plastic wrap) to trap body heat. Place warm (not hot) water bottles or chemical heat packs on the armpits, groin, and neck. Example: 'Wrap the person in a sleeping bag with a warm water bottle (wrapped in cloth) in the armpits. Do not rub extremities.'
   ```
3. ```
   If the person is unconscious or not shivering (severe hypothermia), call 911 immediately. Handle them gently (no rough movement) and do not give anything by mouth. Use passive rewarming only. Example: 'If the person is unconscious, not shivering, or has a core temperature below 90°F (32°C), call for emergency help. Do not move them roughly; do not give drinks.'
   ```

## 无效尝试

- **** — Alcohol causes vasodilation, increasing heat loss. It also impairs judgment and coordination, worsening the situation. The feeling of warmth is deceptive. (90% 失败率)
- **** — Rubbing can cause cold blood from the extremities to flow to the core, causing afterdrop and potentially triggering cardiac arrhythmias. It also damages cold-injured tissue. (85% 失败率)
- **** — Caffeine is a diuretic, leading to dehydration, which impairs the body's ability to generate heat through shivering. It can also increase heart rate, which may be dangerous in hypothermia. (70% 失败率)
