It might be tempting to crank up the heating when you go to bed as we get into the winter months.
But sleep experts have warned against keeping radiators on while you slumber.
James Wilson, aka The Sleep Geek, says sleeping with central heating on can "cause issues" for people in the night.
He warns it encourages "large temperature fluctuations" which our bodies "struggle to deal with". This could make it harder to fall asleep or mean that your sleep during the night is disrupted.
Instead of making your room too warm and cosy, he advises keeping the bedroom a little cooler than the rest of the house.
He says this will "encourage the drop in core temperature we need to sleep".
James explains: "Often we are told the bedroom should be 16C to 18C but for some people that is too cold, so it is better to focus instead on simply making the bedroom feel cooler than the rest of the house.
"The more important temperature for sleep is the one between the mattress and the duvet, which should be between 27C and 29C."
If you think the temperature in your bed isn't right, he continues to say you might want to consider getting a different duvet.
"If your duvet is too heavy it can make you hotter, so go for a lower tog rating or a separate duvet from your partner."
He adds that the mattress could also be causing you problems, especially if you have a memory foam one, as the foam retains body heat.
And it turns out hot water bottles can mess with your sleep as well, as they can make the bed feel "too cold when they are no longer warm in the middle of the night".
Christabel Majendie, sleep expert at Naturalmat, says it’s important to ensure your bedroom isn’t too hot or too cold.
She said that a hotter environment is more disruptive to sleep than a cold one is, and the artificial heat can ‘wreak havoc’ on your body.
Hot, dry air can leave you dehydrated, and even reduces your ability to fight off infections. Leaving the central heating on all night can also leave you thirsty and with a dry mouth.
She said: “We sleep better in temperatures between 16-18 degrees so set the thermostat accordingly and regulate body temperature through the night with bedding, such as an extra blanket which you can add or remove.
"It may be worth wearing socks in bed if you suffer from cold feet as this can disturb your sleep”.
