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.
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.
Experts in what field? Fucking doorology?

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

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