It’s important to know which plants can effectively improve your indoor air quality so that you can choose the right plants to benefit your lifestyle.
In this article, we’ve put together a list of 10 indoor plants that release oxygen at night and we’ll take a look at the benefits they can provide for your health and well-being.
Indoor Plants for Clean Air
Having enough oxygen indoors is crucial for maintaining good health and well-being. Oxygen is essential for the human body to function properly, and a lack of oxygen can cause a range of health problems, including fatigue, headaches, dizziness, shortness of breath, and even unconsciousness.
In indoor spaces, oxygen levels can be impacted by a variety of factors, including poor ventilation, high levels of indoor pollutants, and the presence of certain chemicals. This can be especially problematic in tightly sealed buildings, which can trap indoor pollutants and reduce the flow of fresh air.
Plants can be a helpful tool for improving indoor air quality and increasing oxygen levels. Through the process of photosynthesis, plants absorb carbon dioxide and release oxygen, which can help to counteract the effects of indoor pollutants and improve the air quality in indoor spaces.
Plants require minimal maintenance and can be a more cost-effective solution in the long run. However, they may not be as effective at removing certain types of pollutants, and the number of plants needed to achieve significant air purifying effects may be higher.
Plants are also natural air purifiers that can remove harmful chemicals such as formaldehyde, benzene, and trichloroethylene from the air, and can also help to regulate humidity levels. In addition to their air-purifying benefits, plants can also improve mental health and create a more calming and soothing environment.
When Do Plants Release Oxygen?
While we know that plants release oxygen, it sits important to know how and when plants tend to do this.
Most plants release oxygen during the day through the process of photosynthesis and release carbon dioxide at night through respiration. There are a few exceptions to this rule. Some plants, like succulents, orchids, and aloe vera, are known to release oxygen at night.
Plants that release oxygen at night are typically called CAM (Crassulacean Acid Metabolism) plants, and they have a different process for photosynthesis that allows them to store carbon dioxide during the day and release it at night. This process enables them to continue releasing oxygen even in the absence of sunlight. This can be beneficial for improving air quality in indoor spaces while people are sleeping.
It’s good to note that while the amount of oxygen released by plants at night is generally not enough to significantly impact the oxygen levels in a room, having these plants in a bedroom can still be beneficial for improving air quality and creating a relaxing atmosphere.
Here are 10 plants that are known to release oxygen at night, although the amount of oxygen released is typically quite small, they do make a difference to your indoor spaces.
Aloe Vera (Aloe barbadensis)
Aloe vera is a succulent plant species that are native to North Africa, the Canary Islands, and parts of the Arabian Peninsula. It belongs to the family of plants known as Xanthorrhoeaceae.
