Heating
Only if room drops below 16°C
Sleep research shows quality drops when bedrooms fall below 16°C
Bedding
Thick duvet + extra layer
Cold night — your body needs insulation to maintain core temperature
Fan
Not needed
Cool enough without — save the electricity
Based on temperature, dew point, wind, and overnight cooling
Why this matters
At 7°C outside, your bedroom could drop below 14°C by morning — the point where cold itself starts disrupting sleep. The risk isn't discomfort (a thick duvet handles that), it's waking in the early hours as your body diverts energy to stay warm.
Dew point is just 3°C — dry, fresh air. This is the kind of night where an open window does exactly what you want it to: brings in cool, comfortable air that helps your body maintain its natural overnight temperature drop.
The week ahead
Sat will be the best night, tue the worst.
