Is it healthy to have lots of indoor plants?
There is an ongoing discussion about the types and numbers of plants needed in homes to achieve health benefits. However, the greater the number of plants used, the more likely the benefit to air quality and overall well-being. In their study, named “Potted plants do not improve indoor air quality: a review and analysis of reported VOC removal efficiencies,” researchers found that to achieve the same benefits seen in other research studies, you would need 10-1,000 plants per square meter of floor space in your home, office or other indoor .
Is it okay to sleep in a room with lots of plants?
Some people worry that plants in the bedroom will cause carbon dioxide (CO2) poisoning, but this is an urban myth. It’s true that when you turn off the light, the plant no longer has a source of energy, and so photosynthesis stops. During the day, the plant exhales much more oxygen than it inhales, thus providing fresh air. However, at night the plant cannot photosynthesise due to the lack of light and therefore the plant takes up more oxygen. This is undoubtedly a disadvantage, but not yet a reason to ban the plant from the room.
