Tonight's plan
Warm overnight — you'll need help cooling down to sleep well.
Windows
Closed
Warmer outside than a good bedroom — opening them makes it worse, not better
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
Recommended
Aim across your body, not directly at your face — drops perceived temp by 2–3°C
Based on temperature, dew point, wind, and overnight cooling
Why this matters
20°C is above the ideal 16–18°C range, but not dramatically. Most people will still fall asleep — it's staying asleep through the early hours that becomes harder, because your body can't complete its natural cooling cycle.
The air barely cools overnight — just -0.3°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.
