Make your bedroom winterproof

A bedroom that's right for July is rarely right for January. Cold floors, draughty windows, summer-weight bedding, and the morning chill on a cold tile bathroom — all add up to a room that's working against you. Winterproofing isn't about expensive renovation. It's about a handful of swaps and small additions that make the room feel ten degrees warmer without changing the thermostat. Here are the upgrades that genuinely work.

1. Switch the bedding
2. Add layers (everywhere)
3. Tackle the draughts
4. Small warmth extras
5. The temperature balance

Switch the bedding

The single biggest comfort gain in winter comes from getting the duvet right. A summer-weight duvet under January temperatures means waking up cold or piling on extras. Switch to a winter duvet — bamboo winter duvets retain heat without the suffocating feel of synthetic fillings, and they regulate moisture so you don't wake up clammy.

Also: a flannel-style or warmer-feeling top sheet helps if you find bare bamboo too cool to first slip into on cold nights. Most people don't need this — bamboo warms up to body temperature within minutes — but it's worth knowing.

Add layers (everywhere)

Cold rooms feel less cold when there's visual and physical layering:

• A throw at the foot of the bed — easy extra warmth on the coldest nights
• A rug next to the bed — cold floors are often the worst part of winter mornings
• Heavier curtains — they actually reduce heat loss through windows by 10–25%
• An extra blanket folded inside the duvet cover — old trick, surprisingly effective

Tackle the draughts

Most bedrooms lose more heat to draughts than people realise. Quick fixes:

• Draught excluders at the bottom of doors
• Self-adhesive foam strips around windows that don't seal well
• Thermal curtains (or thicker curtains over thin ones) — close them at dusk
• Block the chimney with a chimney balloon if you have an unused fireplace

None of these are expensive. Together they can change how a bedroom feels overnight.

Small warmth extras

• Hot water bottle in the bed 30 minutes before you get in — the most underrated winter luxury
• Slippers and a dressing gown next to the bed — those first 30 seconds out of bed shouldn't be a punishment
• Warm-toned lighting — physically the same temperature, but psychologically warmer than cool-white bulbs
• A hot drink on the bedside — chamomile tea, warm milk, anything not caffeinated

The temperature balance

The trap with winterproofing is overheating the bedroom. Cranking the thermostat to 22°C ruins sleep — a 16–19°C bedroom is actually optimal even in winter. The goal is to be warm IN the bed (good bedding, layers) without overheating the room. See our temperature guide.

Bamboo bedding helps with this exact balance: it retains warmth from your body but releases excess heat, so you stay warm without overheating. That's especially valuable in winter, when most bedding either feels cold or feels stifling.
