NASA’s 1989 study of a plant’s leaves, roots, soil, and associated microorganisms sought to evaluate plants as a possible means of reducing indoor air pollutants. Since that initial groundbreaking work, many other studies have been conducted. At every turn, the health benefits of plants is confirmed.
It shouldn’t really surprise us, though. Simply walk into a room that includes healthy plants as part of its decor and you will experience a positive reaction, whether you consciously realize it or not. Our response to indoor plants is an extension of our love of nature. It feels good to be around plants.
