Do you remember? A plant releases oxygen during the day, by converting carbon dioxide in the air, moisture in soil and sunlight. But at night, this process is reversed. Because there is no sunlight, plants convert oxygen into carbon dioxide.
In the old days
In hospitals, they removed plants from patients’ rooms at night because plants use oxygen at night. They were afraid that the plants would consume too much oxygen.
But now we know better. Plants are good for you. Generally speaking, plants have a positive effect on the humidity and oxygen levels in your room. Research by NASA has even shown that there are several plants can purify air. These include the Peace Lily (Spathiphyllum), English Ivy (Hedera), Mother-in-Law’s Tongue (Sansevieria) and Dracaena reflexa. So which plant do you keep in your bedroom?
