Air quality i assume, i started leaving it open after getting a CO2 meter in my room. Having a larger volume of air to pull from, massively reduces the CO2 level in your room. My morning level went from 2500+ ppm down to ~700ppm. If you have plants it probably helps a lot too.

Idk if thats what these "experts" are talking about but thats just my experience.

But plants need light to convert CO2. At night they actually use up oxygen. Those ungrateful pricks.

Keep in mind that most plants only process co2 by day but there are some exceptions, afaik Sansevieria. But depending on the volume of you bedroom I would also recommend to leave the door a bit open to keep co2 levels at bay.

This sounds a lot like an issue that can be solved by slightly opening a window

Huh interesting. Searched out of curiosity, and I found 1 article saying you should close it as it will lower the temp throughout the night to allow for a more peaceful sleep and also for fire safety. Then right below was a link to another article stating you should leave it open as it will lower the temp via circulation. Fun, don't think I've seen such mixed results.

Whatever the positives are. This are my reasons to keep it closed.

Noise. It gets quite loud when my door isn't closed.
Temperature. I don't wanna heat the whole hallway.
Security. I don't feel safe when the door is open.
Mosquitoes. I don't like having those in my room.
