Keeping houseplants can be good for your physical and mental health. Research, including a small study involving 24 young men published in 2015 in the Journal of Physiological Anthropology, suggested that nurturing a plant and watching it grow can reduce stress levels, soothe anxiety, and help you feel calmer.

The 1989 NASA Clean Air Study, which was formally known as A Study of Interior Landscape Plants for Indoor Air Pollution Abatement, famously found that some plants could remove toxins from the air through the process of photosynthesis.

As plants photosynthesise, in a process called photosynthesis, they remove carbon dioxide from the air and produce oxygen. Plants can also absorb toxic chemicals from the air, and either metabolise them or incorporate them into their own tissues, according to a study and review of prior research published in March 2018 in Wireless Sensor Network.

Tending to any kind of plant can be beneficial for your mental health. But if you’re also looking to improve the air quality in your home, get some tips here.
