Tonight's plan
Comfortable range tonight — good sleeping weather.
Windows
Open after 4am
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
Normal duvet
Standard weight — tonight sits right in the comfortable range
Fan
Not needed
Cool enough without — save the electricity
Based on temperature, dew point, wind, and overnight cooling
Why this matters
At 17°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.
The dew point — 17°C — is the real problem tonight. High dew point means your sweat can't evaporate, which is your body's primary cooling mechanism. This is why humid heat feels worse than dry heat at the same temperature, and why a fan helps more than you'd expect.
The week ahead
Mon will be the best night, thu the worst.
