Doctor explains why sleeping with the windows closed could be ruining your sleep

There could be a simple reason why you aren't sleeping so great A doctor has said the simplest thing might be preventing you from getting a good nights sleep each night. Everyone loves a good sleep, but while you might hope you wake up feeling refreshed and ready to attack the day each day... that is rarely the case. Well, whether you sleep with the window open or not could be contributing to a poor night's sleep, according to a doctor. If you lived in a perfectly warm climate, sleeping with the window open might be an easy fix, but if you are in a cold climate, yeah, that just isn’t happening. After hearing the potential health benefits, you might attempt to brave it. It's worth noting that there are a lot of other factors with sleep as well, like your mattress and pillows, screen time before bed, or eating late at night. But, having the window open could also be a factor when it comes to getting enough shut eye. Dr Eric Berg took to TikTok to share why this is exactly, and I'm sure many readers may have made a pretty close guess by this point.

Cold or not... you might need to brave it (Kinga Krzeminska / Getty) If you guessed that it was because closing the window means there will be less oxygen and more CO2 in the room, congratulations, you are bang on the money. Dr Berg explained: "You're in a room when the windows are not open and you're not getting enough oxygen, because maybe you don't also have enough plants in your room which give you oxygen, you may have a tendency to have more CO2 in that room. "And just that alone can affect your sleep in a negative way. This is why, when you open the window if you can, or you get a plant next to where you're sleeping, you can definitely sleep better just for the fact that you're increasing the oxygen and you're lowering the CO2.

The doctor insisted people needed to get more oxygen(TikTok / Eric Berg) "So many people are spending all day in a room with a higher level of CO2 and not enough oxygen." Fortunately, if the thought of opening the window in the winter months has you shivering despite wearing four layers and being under two blankets, fear not. There are alternatives to reducing the amount of CO2 in your room. That is, of course, getting a plant to put into your room. However, if you are the sort of person who only has to look at a plant for it to start shrivelling up, then sadly opening the window may be the only option.
