House plants do more than just decorate the house. They brighten the rooms, enhance creativity, boost mood, maintain indoor humidity level and naturally filter air pollutants. However, there is one room where even the greatest Feng shui doesn’t recommend you to have any plant, and that’s the bedroom. The bedroom is meant for resting and you don’t require anything that will interfere with your sleep. Plants in the bedroom work in a reverse system which isn’t ideal for someone asleep. Sleep brings the energy down and the room becomes quiet while plant works in an upward direction which is quite the opposite. The energy displayed by plants is strong and vibrant which is not the required energy while asleep. However, this remains to be a hot debate on whether you should or shouldn’t have plants in the bedroom. Here are some reasons why it’s not healthy to sleep with plants next to you.

At Night, Plants Emit Carbon Dioxide

Not only do plants release oxygen but they also emit carbon dioxide. During the day plants produce oxygen through a process called photosynthesis where they convert carbon dioxide and water into food in the presence of sunlight.But during the night photosynthesis can’t take place due to the lack of sunlight hence the plants emit more carbon dioxide than they absorb. To support this, a statement made in the Ask a Scientist section of the U.S. Department of Energy stated that “plants release carbon dioxide during the respiration at night. Additionally, the carbon dioxide released during the night compete with oxygen in your room and this is how it affects your sleep.

How Carbon Dioxide Emitted by Plant Affects Sleep

Carbon dioxide can either be released in high doses or low doses. If we have high levels of carbon dioxide in the room, then it can affect your concentration and make you feel drowsy while mild levels of it in your blood stimulates sleep. At night the carbon dioxide released by plants causes hypercapnia, an abnormal amount of carbon dioxide in your blood. This condition can trigger a reflex that increases your breathing pattern in search of more oxygen. Due to the extra carbon dioxide in your room, the brain regulates its amount in your bloodstream. You begin to over-breath to compensate for the higher levels of carbon dioxide. This is how your entire night becomes a mess and you keep turning and tossing in bed. At some point in the middle of the night, you will be turning your head around as you gasp for more oxygen.

Some Plants Emit Oxygen at Night

This is referred to as a reversed respiration cycle. Not all plants release carbon dioxide at night. Some emit oxygen during the night. This is how it happens. Some plants trap the oxygen released during the day as a way of protecting themselves from loss of water. At night the plants open their pores to release the trapped oxygen because the temperature has cooled down. Now some might argue that since these plants emit oxygen at night, then they are perfect for your bedroom. But that’s not the case and you might want to have a look at this first.

Effects of Oxygen on Sleep

Oxygen is crucial for human beings’ survival. However, while asleep the amount of oxygen we require should be minimal. Studies suggest that too much oxygen keeps us awake. Other sources such as Web MD and Fox News have an article teaching us on how to stay awake by practicing deep breathing which increases oxygen intake and stimulates blood circulation yielding more energy. Moreover, higher oxygen levels reduce carbon dioxide in our blood which negatively affects our sleep quality. This is demonstrated in one study by the National Center of Biotechnology Information, which found that high levels and low levels of carbon dioxide in the bloodstream negatively affects the quality of your sleep.


You have all the facts you require to understand why plants aren’t good for your bedroom. Unless you have an extra big bedroom where you can place the plant several meters away from you, then there’s no need to disrupt your sleep with something that can be avoided. But still, you can have the plants in other rooms of the house. If you had a busy day at work, you find such rooms with plants very comforting. However, don’t rely on plants alone to bring a good climate to your house. Make good use of the ventilation, and keep the windows open.
