I always like to find and share the scientific evidence of what I am studying because I am allergic to bullshits and misconceptions.

A really bad one that haunted me, especially when I was a kid, is that because plants produce CO2 at night we should get rid of them at least in our bedrooms.


Plants breath and make photosynthesis every day, for 24 hours. During the photosynthesis they produce oxygen, during respiration they consume oxygen and produce CO2.

However, the amount of oxygen plants release is way bigger than the amount of oxygen they consume for respiration.

Talking about scientific evidence, today I want to share with you this short TED talk where researcher Kamal Meattle shows how an arrangement of three common houseplants, used in specific spots in a home or office building, can result in measurably cleaner indoor air.

Kamal became allergic to the air of Delhi, the city where he was living, and he was risking to die.

He found out that simply by growing three plants (Areca Palm, Mother-in-law’s Tongue and the Money Palm) there was no need to open the windows for changing the air because the plants are able to massively produce oxygen. All of them are very common and easy to grow, so you can grow them to have fresh air in your house.
