Houseplants, beyond their aesthetic contributions to a living space, also significantly aid in improving indoor air quality. This revelation, backed by pioneering research from NASA in the 1980s, emphasized that certain indoor plants have unique air-purifying properties. They essentially act as natural air filters, absorbing harmful compounds and replenishing the environment with oxygen.
Foremost among the air purification benefits of houseplants is their ability to absorb pollutants through their leaves and roots, converting them into harmless substances. They function on a microscale like a mini respiratory and digestive system, taking in carbon dioxide and volatile organic compounds (VOCs) present in the indoor environment, and releasing clean, oxygen-rich air.
VOCs are a group of carbon-based chemicals that easily evaporate at room temperature, emanating from many household products such as paints, varnishes, cosmetics, cleaning solutions, and even printers. These often contain harmful compounds like benzene, formaldehyde, toluene, xylene, and ammonia, which can cause a range of health problems, including headaches, dizziness, respiratory diseases, and in severe cases, even cancer.
One might wonder how significant the plant’s role could be in combating these hidden threats. Studies and experiments conducted over the years have offered startling insights into this. A research experiment reported by NASA revealed that certain indoor plants could remove up to 87% of air toxins in a 24-hour period. This unmistakably underscores the remarkable potencies houseplants possess as biofilters.
Houseplants like the Peace Lily, English Ivy, and Spider Plant are particularly efficient at absorbing formaldehyde. In contrast, the Boston Fern is known for its ability to humidify the air and eliminate xylene and toluene. Snake Plant, also known as Mother-in-law’s tongue, is beneficial for the bedroom as it absorbs carbon dioxide and releases oxygen during the night, a contrast to most houseplants which perform photosynthesis during the day.
Other benefits of air purification by houseplants extend to the psychological domain. The presence of plants is seen to reduce stress, increase feelings of well-being, and improve concentration and memory. They contribute to a sense of tranquility and comfort, playing a part in reducing blood pressure and promoting restful sleep.
The benefits of indoor plants also extend to the workplace, enhancing productivity, reducing fatigue, and even lessening the effects of common ailments such as colds, sore throats, coughs, and flu-like symptoms. They create a more inviting and refreshing office environment, proven to boost mood and stimulate creativity.
Now, while harnessing the benefits of houseplants, it’s important to consider the care they require. Typically, most indoor plants thrive at room temperature, with access to indirect sunlight. They want to be watered regularly but resent having waterlogged roots. Houseplants are also at risk from pests, just like outdoor plants, and should be checked frequently for signs of disease. Indoor plants are relatively low maintenance and only require minimal attention, making them a worthwhile addition to any indoor space.
However, bear in mind that houseplants alone cannot entirely purify the air in your home. They should be used in combination with other methods of reducing indoor air pollution, such as maintaining good ventilation, limiting the use of harmful chemical-based products, and avoiding smoking indoors.
In conclusion, clean air is not just a luxury but a necessity to maintain a healthy life. Many scientists and environmentalists are putting forward “green building” concepts such as “building-integrated vegetation” and “phytoremediation” to implement plants for addressing broader air quality issues. By incorporating houseplants into our homes, schools, and workplaces, we contribute to creating healthier and more breathable indoor environments. Not just a decor item, these plants could be a critical solution in maintaining high indoor air quality in an increasingly polluted world.
Further still, these houseplants, with their air purifying benefits, are also gateways to fostering an intimate relationship with nature. Through their everyday presence, we are reminded of our inherent link with the environment, and our responsibility towards it. In tuning with nature’s cycles, nurturing growth, and witnessing life in our indoor plants, we enrich not just our homes but our lives as well.
