The 3 AM night sweat isn't just about heat; it's a massive adrenaline dump. Your brain thinks you're in danger because your internal thermometer is malfunctioning. The goal isn't just to cool down, but to calm your 'fight or flight' response.
The 3-Step Rescue
1. **Evaporative Cooling**: Remove layers and use a cool (not ice-cold) cloth on your wrists. 2. **Box Breathing**: Inhale for 4, hold for 4, exhale for 4, hold for 4. This tells your brain the adrenaline spike is over. 3. **Hydrate**: Sip room-temperature water with a pinch of salt.
Prevention
- Keep a 'rescue kit' (water, fan, dry shirt) by the bed.
- Log the trigger in Periwell (was it spicy food? alcohol? late stress?)
