With temperatures dropping even lower this week as we head towards Christmas, your bedroom might be feeling colder than ever. Not only is this uncomfortable, but it can also significantly affect your sleep, so how can you keep your bedroom cozy and comfortable without spending big on energy bills?
The key, say our HVAC pros, has nothing to do with your thermostat, radiators, or even your bedding. Instead, it all comes down to the position of your bed. Here, they explain this simple bedroom tweak to help you avoid any cold-weather sleeping mistakes.
This One Bedroom Tweak Will Boost Cozy Comfort
Designing a bedroom for better sleep often comes with the considerations of choosing colors to make a bedroom feel warmer, but, as lovely as they may look, these won't actually keep you warm while you sleep.
Instead, says Josh Mitchell, HVAC expert and founder of AirConditionerLab, it's all to do with where your bed is placed within your bedroom layout.
'Putting your bed against an exterior wall in winter makes the whole sleep setup colder,' he explains. 'That wall is always losing heat to the outside. Even insulated walls drop in temperature faster than interior ones.
'During chilly nights, I’ve measured surface temps of 45 to 55°F on exterior walls, while the air in the same room held steady at 68°F. So even if the thermostat is doing its job, your body is pressed against a surface that’s pulling heat away for six to eight hours.'
And, as Josh warns, 'That's the kind of steady heat loss that leads to poor sleep, cold wake-ups, and overcompensating with more blankets or space heaters.
'People often think the room is underheated, but the problem is radiant heat loss to cold surfaces. You lose heat not just through the air, but also to whatever your body is touching,' which can seriously hinder any efforts you've made to sleep better.
What to Do Instead
The simplest way to combat this and help you fall asleep faster and wake up more refreshed is to know exactly where a bed should be placed in a room.
Josh advises moving the bed to an interior wall, explaining, 'Interior walls are surrounded by conditioned space on both sides. They stay close to room temperature, usually within one to two degrees Fahrenheit of the air itself. That reduces heat loss through your back and head, keeps the sleep environment more stable, and stops those cold wake-ups around three or four a.m. when the house is at its coldest
'I’ve seen people move their bed just one wall over and cut their space heater use by three to five hours per night. That’s 50 to 70 hours of heating per month less, which translates into lower bills and better sleep.'
Glenn Cault, HVAC and air quality expert and CEO at Gault Heating & Cooling, adds that if you can't fully move your bed, even moving it just a little can make a big difference.
'Against an interior wall or diagonally in a corner formed by two interior walls are the two "warmest spots" of the room,' he advises. 'But even moving a bed just 12–18 inches away from a window and exterior wall can reduce the radiant chill you feel. Even double-pane windows and well-insulated walls feel colder than interior walls and pull away your body's heat even if you don't touch it directly.'
To further help cut energy bills, you can also:
- Use a heated mattress pad instead of a blanket: 'It warms you from below, runs at a lower wattage, and retains heat under the covers rather than losing it into the air,' says Josh. For this, we recommend the Sunbeam Electric Restful Quilted Heated Mattress Pad, available at Amazon, which is a number one bestseller. You can also use a hot water bottle for a more affordable fix.
- Lay down a thick rug or carpet if you have bare flooring: As Josh explains, even with central heating on, rooms with cold floors can drop two to four degrees Fahrenheit overnight. This is amplified in homes with crawlspaces or basements lacking in basement insulation ideas.
- Keep bedding breathable but layered: The best way to stay cozy is by layering natural materials, like cottons and wool. Then, you can add or remove layers as you need. You can also make bedding feel warmer in winter by opting for a higher tog duvet or adding a throw blanket. I've been testing and loving the Bedsure Gentlesoft 2-in-1 Comforter Set and Detachable Fluffy Blanket available at Amazon in this cold weather.
- Check your vent placement: 'I’ve been in bedrooms where the supply vent was working fine, but a bed frame was blocking the only return,' warns Josh. 'That traps warm air near the ceiling, leaving the lower half of the room freezing. If the air can’t circulate, no schedule or thermostat setting will fix the cold.'
- Use a programmable thermostat: As Chris Hays, owner at Local Roots AC and Plumbing, advises, 'A programmable thermostat is effective. You can temper the room 30 minutes before bedtime to ensure a comfortable temperature for the night's rest.' The Sensi Smart Programmable Wi-Fi Thermostat available at Walmart is a bestseller.

'A lot of heat issues aren’t about adding more heat – they’re about keeping what’s already there,' adds Josh. 'Switching walls is one of those low-effort, high-impact changes that people don’t think about until someone points it out.'
