Why Weather Matters for Sleeping with Windows Open
Sleeping with your windows open can improve air circulation and cooling, but only when the weather supports it. Factors like high humidity, poor air quality, or strong winds may make it uncomfortable—or even unsafe.
Ideal Conditions:
- Temperature between 12–22°C (54–72°F)
- Dew point under 16°C (61°F)
- Air Quality Index (AQI) under 50
- Rain chance below 30%
- Winds below 10 m/s (22 mph)
