Ever since the Greeks and Romans started bringing plants from outside, mankind has lived along with plants. Put in pretty vases, they create a very cosy feeling, as well as bringing liveliness with their greenery. However, plants in general are beneficial to our health and this holds no exception to indoor plants. Without further ado, here are the 5 healing powers of indoor plants.
We all know that as we inhale oxygen and expel carbon dioxide; plants do exactly the opposite with photosynthesis. Plants help to increase oxygen levels, and our bodies appreciate that. However, during the night most plants stop photosynthesizing, which means only a few special plants like orchids, succulents and epiphytic bromeliads help during this time. Use these plants in bedrooms to keep the oxygen flowing at night.
Studies show that outdoor plants, because of the water trapped in their roots, accounts for about 10 percent of the moisture in the atmosphere. The same thing happens at home, which does increase the humidity but also decreases the incidence of dry skin, colds, sore throats and dry coughs.
NASA has spent a lot of time researching air quality in sealed environments, which makes sense. Extensive research by the space agency discovered a then-new concept in indoor air quality improvement in which plants play a pivotal role: “Both plant leaves and roots are utilized in removing trace levels of toxic vapours from inside tightly sealed buildings. Low levels of chemicals such as carbon monoxide and formaldehyde can be removed from indoor environments by plant leaves alone.”
Bringing flowers or a plant while visiting a hospital patient may be an old practice, but so effective are plants in helping surgery patients recover that a study recommends them as a “non-invasive, inexpensive, and effective complementary medicine for surgical patients.” The study found that viewing plants during recovery from surgery led to a significant improvement in physiologic responses and lower ratings of pain, anxiety, and fatigue as compared to patients without plants in their rooms.
A number of studies with both students and workers reveals that studying or working in the presence of plants can have a dramatic effect. As with simply being in nature, being around plants improves concentration, memory and productivity. Being “under the influence of plants” can increase memory retention up to 20 percent. Two Norwegian studies found that worker productivity is greatly enhanced by the presence of plants in the office. “Keeping ornamental plants in the home and in the workplace increases memory retention and concentration.”
