# AI 建议在热浪期间关闭所有窗户并在密封房间使用风扇

## 根因

在无通风的密封房间中，风扇循环热空气，加速脱水和热衰竭；在95°F（35°C）以上不提供冷却，反而可能升高核心体温。

## 解决方案

1. ```
   夜间开窗，用风扇引入凉风；白天拉上窗帘并关窗以阻挡阳光热量。
   ```
2. ```
   如果可用，使用空调；否则，前往公共降温中心或有气流的阴凉户外区域。
   ```

## 无效尝试

- **** — Using a fan at high speed in a hot room creates wind that increases evaporation but does not lower air temperature; it can cause heat cramps. (80% 失败率)
- **** — Placing ice in front of the fan in a sealed room increases humidity, worsening heat stress. (75% 失败率)
- **** — Keeping windows closed traps heat from the day; without cross-ventilation, the room becomes an oven. (90% 失败率)
