Tonight's plan
Slightly warm and humid tonight — manageable with the right setup.
Windows
Open after 5am
Cooler air arrives later — wait for it, then open wide
Heating
Off
Warm enough — heating would make it harder to sleep, not easier
Bedding
Light duvet or top sheet
Enough to feel covered, light enough to not trap heat
Fan
Helpful if muggy
Humidity is the issue more than heat — airflow helps sweat evaporate
Based on temperature, dew point, wind, and overnight cooling
Why this matters
At 19°C, tonight sits right in the zone where sleep research says most adults sleep best. Your body can regulate its temperature naturally without any intervention.
Dew point is 15°C — not extreme but enough to make the warmth feel stickier than the temperature alone suggests. The gap between temperature and dew point is what determines whether the air feels fresh or muggy.
The week ahead
Mon will be the best night, fri the worst.
