A houseplant is a plant that is grown indoors in places such as residences and offices, namely for decorative purposes, but studies have also shown them to have positive psychological effects. They also help with indoor air purification, since some species, and the soil-dwelling microbes associated with them, reduce indoor air pollution by absorbing volatile organic compounds including benzene, formaldehyde, and trichloroethylene. While generally toxic to humans, such pollutants are absorbed by the plant and its soil-dwelling microbes without harm. Find out more here.
Indoor plants may help reduce stress levels
A study published in the Journal of Physiological Anthropology found
that plants in your home or office can make you feel more comfortable,
soothed, and natural. They found that the indoor gardening task lowered
the stress response in participants. The computer task, on the other
hand, caused a spike in heart rate and blood pressure, even though the
study participants were young men well-accustomed to computerized
work.
Real plants may sharpen your attention
Sorry, plastic plants won’t help you pass your exams. In a small study
involving 23 participants, researchers put students in a classroom with
either a fake plant, a real one, a photograph of a plant, or no plant at
all. Brain scans of the participants showed that the students who
studied with real, live plants in the classroom were more attentive and
better able to concentrate than students in the other groups.
Plants may help you recover from illness faster
Being able to look at plants and flowers may speed your recovery
from an illness, injury, or surgery. A 2002 review of the research
revealed that people recuperating from several kinds of surgery needed
less pain medication and had shorter hospital stays than people who
weren’t looking at greenery during their recovery periods.
