The Benefits of Indoor Plants
by Kathleen Abdo, Plant Education

While we are spending the winter indoors, consider how our indoor air quality affects our health. Having stagnant air in our homes allows pollutants to buildup.  NASA studied ways to clean the air in space stations and found common house plants are very efficient in cleaning common toxins in air.  Indoor toxins include carbon dioxide, trichloroethylene, formaldehyde, benzene, xylene and ammonia,  These toxins are given off by items around the house or space station.  Plants purify air by photosynthesis and microbes in the soil.  NASA calls plants “nature’s life support system."

Other studies have shown that people feel better having plants in their environment.  For example, green plants produce a positive attitude and lower blood pressure. One can say that plants make people smarter by helping them stay alert and reduce mental fatigue. A few beneficial plants to have around the house are Poinsettia, Spider Plant, Ficus, Garden Mum, Peace Lily, Boston Fern, Snake Plant, Bamboo Palm, and Aloe Vera.  While it’s dreary outside brighten your home and improve air quality with plants.
