Start With the Duvet

If there is one change that transforms a bedroom overnight, it is swapping to a thicker duvet. Most of us sleep under a 10.5 tog duvet for much of the year, but once the temperature drops, a 13.5 tog or even a 15 tog option makes an enormous difference. Tog ratings are simply a measure of warmth: the higher the number, the more heat the duvet traps. For a typical British winter, a 13.5 tog suits most centrally heated homes, while a 15 tog is ideal for draughty period properties, unheated upstairs rooms, or anyone who simply feels the cold.

Do not overlook the cover itself. Brushed cotton, flannel, or a soft cotton-polyester blend feels noticeably warmer against the skin than crisp percale. Flannel is brushed on both sides, which traps a thin layer of air and gives that gentle, fuzzy warmth you associate with winter pyjamas. If you share a bed and one of you runs hot, consider two single duvets on a double bed rather than one large one. It sounds unconventional, but it means each of you can choose your own tog rating, and no one ends up overheating or shivering.

Layer Your Bedding Like an Expert

Snugness comes from layers, not from one heavy item. Think of your bed as you would dress for a cold day: several thin layers trap more warmth than a single thick one. A good winter arrangement might be a fitted flannel sheet, a brushed cotton duvet cover over a 13.5 tog duvet, and a cotton or wool throw folded across the foot of the bed. Add a blanket underneath the duvet if your mattress feels cool, or use a mattress topper with a fleecy surface for extra insulation from below.

Change your sheets weekly in winter, just as you would in summer. Clean bedding loft and traps air better, and there is nothing quite like the feeling of fresh flannel sheets on a cold night. If you have a spare set, keep it in the airing cupboard so it is warm when you make the bed.

Warm the Bed, Not the Whole Room

• Hot water bottle: Fill a good quality rubber bottle with hot (not boiling) water, wrap it in a cover or a folded towel, and place it at the foot of the bed twenty minutes before you turn in. Remove it before you sleep if you tend to kick things about.
• Wheat bag: A microwaveable wheat bag warms the mattress where your feet rest and holds heat for a surprisingly long time.
• Electric blanket: A modern electric underblanket on a low setting for half an hour before bed takes the chill off the sheets. Always follow the manufacturer's instructions and switch it off before sleeping unless it is designed for all-night use.
• Socks: A pair of warm bedsocks is one of the cheapest ways to feel snug. Warm feet help you fall asleep faster, so if your feet are always cold, this is the fix.

These small measures mean you can keep the thermostat lower at night, which is better for sleep, kinder to your heating bill, and gentler on the planet. A bedroom around 16 to 18 degrees Celsius is generally considered comfortable for sleeping.

Deal With Draughts and Cold Surfaces

Cold air creeping under the door or through a sash window can undo all your good work. A simple draught excluder along the bottom of the bedroom door costs very little and makes a real difference. For windows, a thermal curtain lined with a thick fabric, drawn fully at dusk, acts as an extra layer of insulation. If you have bare floorboards, a rug beside the bed means your feet land on something soft rather than icy wood or tile.

Also consider where your bed sits. Placing the head of the bed against an internal wall, rather than an external one, keeps you away from the coldest surface in the room. Pulling the bed slightly away from the wall allows air to circulate and helps prevent condensation, which can make bedding feel damp and chilly.

Create a Calm, Restful Atmosphere

Snugness is as much about feeling as temperature. Warm, low-level lighting helps more than harsh overhead bulbs. A small bedside lamp with a warm white bulb, or a string of fairy lights, gives the room a soft glow that signals to your body that the day is winding down. If you read in bed, a clip-on light directs the beam onto the page without lighting up the whole room.

Texture matters too. A chunky knit throw, a velvet cushion, or a woollen blanket draped over a chair all add visual warmth. In a plain bedroom, these touches make the space feel layered and inviting. Add a scented candle or a few drops of lavender oil on a cotton pad near the radiator for a subtle, calming scent, but avoid anything overpowering before sleep.

Finally, keep the room tidy. A clear floor, a made bed, and a surface free of clutter reduce mental whirring and make it easier to settle. A few minutes of tidying before bed is a small ritual that pays off in a better night's sleep.

Small Habits for Colder Nights

• Take a warm bath or shower an hour before bed; the subsequent drop in body temperature encourages sleepiness.
• Have a warm, caffeine-free drink such as chamomile or warm milk.
• Close curtains and blinds at dusk to retain heat, and open them in the morning to let in light and air the room briefly.
• Wear layers you can remove, so you do not wake up overheated in the early hours.
• Keep a folded blanket at the foot of the bed for nights when you need a little extra.

None of these steps requires a big budget or a full redecoration. A thicker duvet, a set of flannel sheets, and a hot water bottle will get you most of the way there. Add a draught excluder here, a warm lamp there, and a plain bedroom gradually becomes a proper winter retreat: a place you look forward to sinking into when the nights draw in.
