Gardening is a rewarding hobby that can pay a host of dividends, both for the planet and the people doing the gardening. Healthy plant life can help clean the air by absorbing carbon dioxide and various air pollutants, while the act of gardening can help gardeners combat stress.
Published in the Journal of Health Psychology, a study from researchers in the Netherlands found that gardening promotes relief from acute stress.
In the study, two groups of participants were asked to complete a stressful task and then instructed to either read indoors or garden outdoors for 30 minutes. After 30 minutes, the latter group had lower levels of the stress hormone cortisol and even reported being in a better mood than the group instructed to read indoors.
But gardening does more than just provide gardeners with a reason to spend some time relaxing outdoors in an effort to relieve stress.
Gardeners who raise certain plants may be able to bring those benefits with them when going inside as well.
According to an article published in the journal Environmental Health Perspectives in October 2011, houseplants can work wonders when it comes to improving overall health, removing toxins from air, soil and water by metabolizing some toxic chemicals and releasing harmless byproducts while sequestering such toxins by incorporating them into plant tissues.
Clean indoor air is important for everyone, but especially so for those people who suffer from respiratory ailments like asthma. In fact, the American Academy of Allergy, Asthma and Immunology considers indoor air filtration an essential part of any strategy to improve respiratory health. But filtration systems and air purifiers are often not enough, and those who want the air in their homes to be as clean as possible may benefit from introducing certain houseplants into their homes. The following are a handful of plants that can help to improve indoor air quality.
â ¢ Aloe vera: Aloe vera might be most often associated with hand creams and hand soaps, but the aloe vera plant, a succulent that even novice gardeners should have no problem growing, can clear indoor air of formaldehyde and benzene, two common byproducts of chemical-based cleaners many people use in their homes.
â ¢ Spider plant: Spider plants are resilient, and that makes them great houseplants for busy men and women who tend to be forgetful when caring for their plants. In addition, spider plants are pet-friendly and can be used to combat benzene, carbon dioxide, formaldehyde and xylene.
â ¢ English ivy: NASA researchers exploring the possibilities of long-term space habitation found that certain houseplants were more effective at cleaning air inside energy-efficient, nonventilated buildings than others. One such plant was English ivy, which can effectively combat the formaldehyde found in certain household cleaning products.
â ¢ Bamboo palm: Bamboo palms also found their way onto NASA's list. Bamboo palm plants thrive indoors, where they are especially effective at filtering out the chemicals benzene and trichloroethylene.
