Houseplants, amongst the concrete jungle in urban areas, provide something more than greenery but also are an essential part of our health and environment. This extensive study reveals the intensive research on the role of house plants in addressing air pollution and enhancing well-being.

1. Beyond Aesthetics: Purifying Indoor Air

NASA’s Groundbreaking Research: A seminal 1989 study by NASA was led by Dr. B.C. Wolverton who proved that indoor plants could absorb harmful toxins like benzene and formaldehyde mainly produced by furnishings, upholstery, and building materials. “Interior Landscape Plants for Indoor Air Pollution Abatement,” is a study which identified specific plants with air purifying capabilities as well as explained the contribution of microorganism in soil to improve indoor air quality.

Later Scientific Studies: After these findings were released by NASA, several studies have been done to confirm and expound on how indoor plants help to reduce air pollutants within buildings. For instance, an article published in American Society for Horticultural Science showed that some plants can minimize levels of indoor ozone which is a hazardous air pollutant.

4. Physical Health: A Lesser-Known Aspect Of Houseplants

Reduction of Airborne Diseases: Studies have shown that plants help to reduce air borne diseases by increasing humidity and reducing dust thereby producing an environment which is less likely to spread colds or other respiratory infections.

Therapeutic Effects of Horticultural Therapy: American horticultural therapy association this practice has been used more frequently by researchers involved in gardening activities to improve mental health. It has been proven through various studies that being engaged with plants helps people recover from sicknesses more quickly , better motor-skilled, and also has a positive affect on health overall.
