It's been proven that humans didn't actually get most of their fresh air from the rainforest, but actually from millions of these algea in the sea... Which is actually more logical, since trees do the opposite at night, kinda undoing any advantage they made during the day... Hence why it's said you should never put a decorative small tree or even plants in the bedroom as they can take away oxygen levels in closed rooms at night. It's even said not to sleep under trees outside at night cause it can cause respiratory problems.

They don't use enough oxygen over night to negate the effect as they use the carbon to grow. It's still bad to have a lot of plants in your bedroom, but it doesn't really matter as long as they are relatively small.

That had me go and look it up and apparently you're right that they use part of the carbon dioxide as energy storage, but as I understand this storage eventually gets released in full when the tree dies too...

Not sure if that would be so much to balance it out again, but it does still diminish their overall effect even more...

It is just how a tree works, it gets the matter to grow from the carbon dioxide. If they are burned or they die this carbon is slowly released again, same way as coal has carbon that is stored until burning

Hence why we're probably breathing more algea-breath while not so terribly much from trees (unless you're standing next to one during daytime). 😅

Why shouldn't you have plants in your bathroom?

They consume oxygen during the night so when you have a lot of them it can cause respiratory problems, that is for the bedroom

An effective HVAC system makes this a non-issue. It isn't like the air is stagnant, the air handler keeps air moving.

From my experience, european homes don't have a lot ov ac or ventilation
