Most people spend the majority of time indoors at home or work. Air conditioning, improved insulation, and energy-saving all reduce air exchange in buildings, so we breathe the same air again and again. Because the modern internal environment is virtually hermetically sealed and the construction materials used, modern synthetic furnishings, computers, electrical equipment, and everyday household products such as cleaning material, can produce harmful substances that are trapped inside the building. THumidity is another important and often underestimated factor in human healthhese all contribute to the well recognised "sick building syndrome". Polluted indoor air, contaminated by volatile organic compounds (VOCs), are a major cause of headaches, nausea, sore & itchy eyes, loss of concentration and other "sick building" symptoms. The simple addition of interior plants is a natural way to help remove these pollutants significantly.
Humidity is another important and often underestimated factor in human health. When humidity levels are too low, individuals are more likely to develop viral infections; when humidity is too high, vulnerability to other disease increases. Plants tend to control humidity to within the optimum range for human health.
Plants absorb carbon dioxide and emit oxygen. This obviously reduces your carbon footprint but also the increased oxygen level refreshes the air -and you! - leading to increased concentration and productivity (in various studies between 10%-15% increase). There is a wealth of scientific study into the beneficial effects of live plants in the interior environment including a large NASA programme
