Warm enough — heating would make it harder to sleep, not easier
Bedding

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 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.
A 5.6°C drop between bedtime and 4am is substantial. This natural cooling aligns with your circadian rhythm — your body temperature dips in the early hours, and the environment cooling alongside it produces the deepest sleep of the night.
The week ahead
Mon will be the best night, tonight the worst.
