10 Ways To Keep Your Bed Warm In Winter

bedroom radiatorThe good news is that it’s much easier to warm your bed than to cool it.

To start with, your own body creates a lot of heat. And while that’s a problem in the summer, it’s a key part of the solution in the winter.

If have enough of the right layers to trap your own body heat in, you can keep your bed warm enough to sleep just by being there.

However, it takes time to warm your bed that way. And nobody likes climbing between icy sheets and shivering for the first few minutes.

So if you live in a particularly cold area, it might help to use a bed heating system, as well as the right kind of winter bedding.

What’s the ideal bedroom temperature?

A lower temperature signals to your body clock that it’s night, and therefore time for sleep. So heating your bedroom too much can have a negative effect on your sleep quality.

Sleep experts recommend a bedroom temperature of between 60 and 67 degrees Fahrenheit (15.5 and 19.5 degrees Celsius). Some will prefer warmer or cooler, but it’s a useful rule of thumb.

So although it’s nice to warm your bed, if you overheat, sweat or feel uncomfortable, try experimenting with cooler temperatures.

1. Heat your bedroom, not the whole house

It’s both inefficient and expensive to heat your entire home all night long. But on the coldest of nights, it might be worth heating just the bedroom, and shutting the door to keep the heat in.

2. Use flannel winter bed sheets

Flannel is the best choice of material for bed sheets in the winter. Flannel is cotton that’s been brushed to make it fluffy, rather than smooth like normal cotton sheets.

All that extras fluffiness means more air is trapped, which makes it a better insulator.

3. Create layers of top sheets and blankets

Rather than just using one thick blanket, comforter or duvet, create layers instead. The idea is to create layers of insulation, trapping air which is a poor conductor of heat.

Layers also work well because you can remove them if you get too warm in the night. Try alternating between thinner and thicker layers to maximize the insulation effect.

4. Choose a warmer comforter or duvet filling

As long as you don’t mind using animal products, the warmest filling for comforters and duvets is down and/or feathers.

Another great choice is wool, which traps air very effectively, while still being more breathable than synthetic fillings.

If you’d prefer to avoid animal-based fillings, then hollow fiber is a good choice of warm material.

Understanding tog values

In some countries, duvets come with a tog value. A tog is a measure of thermal insulation, giving you an idea of how warm you can expect it to be.

As a rule of thumb, aim for these values according to the season:

  • Summer: 3.5 – 7.5
  • Spring and autumn: 7.5-10.5
  • Cold winters: 13.5 – 15

5. Choose warmer blanket materials

If you use a blanket, the warmest materials are wool and cotton fleece. The fibers of these materials are curlier, which creates air pockets that trap your body heat better than flat synthetic fibers.

There are many choices of wool, with sheep and lamb wool being the most common. And if you want the very warmest possible, try a blanket made from Merino, Cashmere, Alpaca, Yak or Qiviut.

6. Use heated bedding

Although it’s possible to warm your bed using just your body and bedding, for some people it still might not be enough. And if you really don’t like getting into a cold bed, perhaps it’s time to warm it up before you actually climb in.

The main choices of heated bedding are heated mattress pads or electric blankets. Mattress pads have the benefit of heating from underneath you, so warm the bed more efficiently. They are also safer as the wires are less likely to bunch up.

But electric blankets might suit some people better. Especially if you don’t want wires beneath you, or find you get a little too hot when the heat is trapped between the bed and your body.

7. Blow some warm air between the sheets

An effective alternative to heated bedding is a climate control system called the BedJet. It’s a personal favorite of mine, and my partner too.

It works by warming air over a ceramic stone in a separate unit, and then blowing that warm air between your sheets and over your body.

It’s fast, effective and has a wide range of temperature settings and features that allow you to warm your bed just right.

8. Wear some warm PJs

Continuing with the theme of creating insulation for your body heat, try wearing some warm flannel pajamas. They also make getting out of bed in the night a slightly less shivery experience.

9. Cuddle up to a hot water bottle

Another way to introduce an extra source of warmth is the simple rubber hot water bottle.

Fill it with hot water (not boiling though), and place it in your bed before you get in. You can then cuddle up to it, or use it to keep your feet warmer for the first half of the night.

10. Snuggle up to your partner

Finally, one your probably already know if you sleep with a partner. Snuggling up together is a great way to insulate your combined body heat, ensuring you keep even more of it from escaping.

  • I have a down alternative comforter on my bed these days. This is on top of a faux shearling blanket. It’s like sleeping in a cloud. When I get too warm, I push back the down alternative comforter and find the faux shearling blanket to be “just right”.

    If I feel chilled before getting into bed, I might run warm water on my feet until they’re toasty. Then put on warm socks. I might pop fleece pjs on to climb into bed. I might switch into the cooler pjs in the night, so I stash cooler ones next to my pillow.

    When I lived in a very cold house in grad school, I had a featherbed mattress topper and a down comforter on my bed. In just a few minutes in that bed, I was toasty.

    • Hi Suz
      Thanks for your comment and for sharing your tips. I like the idea of warming your feet with water before getting into bed – it’s actually the opposite of what I do in the summer to keep cool in bed! Being able to change the temperature by removing or adding layers is also great. And I like the idea of having different bed clothes available too!
