Waking hot and tossing off the duvet? Or curling up cold at 3am? Temperature swings make it harder to drift off and stay asleep. The goal isn’t a laboratory reading — it’s a comfortable, steady climate that feels the same from lights-out to wake-up.

Many people sleep best with the room on the cooler side, roughly 18–20°C. That won’t suit everyone, so treat it as a starting point. Make a couple of small changes, then see how you feel over a few nights.

The plan below keeps things simple: set the room, sort the bedding, add small helpers.

Quick wins tonight

• Lower the thermostat an hour before bed so the room cools gently.
• Crack a window for a few minutes to swap stale air for fresh (if safe and comfortable).
• Dim lights early — cooler rooms often feel cosier with warm lighting.
• Keep a light throw within reach so you can add, not just remove, warmth at 3am.

Set the room

• Target a stable temperature around 18–20°C, adjusting to comfort.
• Airflow helps. A quiet fan on low can even out pockets of warm air.
• Mind humidity. Most people feel better somewhere near 40–60% RH. If the room is damp, air it; if it’s too dry in winter, a small humidifier can soften the air.
• Block draughts at the door and windows so the climate you set actually stays put.

Bedding and sleepwear

Think layers you can tune, not one heavy solution.

• Duvet togs: summer 4.5 tog, spring/autumn 7.5–10.5 tog, winter 13.5 tog (mix and match if your house runs warm or cool).
• Breathable fibres for sheets and covers (cotton, bamboo, Tencel/lyocell) help moisture move away from the skin.
• Cooling pillows or a breathable pillow protector stop heat building around the head and neck.
• Moisture-wicking sleepwear keeps you more comfortable if you run hot or get night sweats.
• Couples: consider separate duvets or a split-weight duvet so each person gets the warmth they like.
