Tonight's plan
A touch warm tonight, but nothing a light sheet won't fix.
Windows
Open after 7am
Cooler air arrives later — wait for it, then open wide — there's a breeze which will clear the room quickly
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
Not needed
Cool enough without — save the electricity
Based on temperature, dew point, wind, and overnight cooling
Why this matters
At 18°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 14°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 air barely cools overnight — just 0.0°C between bedtime and 4am. Your body's circadian rhythm expects a temperature dip during the night. When the environment doesn't provide one, sleep becomes lighter and more fragmented, even if you don't fully wake.
The week ahead
Mon will be the best night, tonight the worst.
