Is it true that houseplants freshen the air in our homes and offices?
If you want to seriously oxygenate your rooms with greenery, you’re going to need a lot of space

TL;DR
- Plants produce oxygen through photosynthesis, but the amount is minimal compared to human consumption.
- Hundreds of plants would be needed to significantly oxygenate a room for one person.
- Sufficient light is crucial for photosynthesis to occur.
- High levels of oxygen indoors can be poisonous.
- Good ventilation, like opening windows, is the most effective way to ensure fresh air.
- Plants can have a beneficial effect on health, as shown in a study where patients recovering from surgery in a tree-facing ward recovered faster.
- Poor ventilation can lead to grogginess and faster transmission of illnesses.
