When we make change towards building wellness, one place we often forget to make changes in our life is in our home. We concentrate on exercise, improving out diet, balancing supplements, adopting practices like yoga or mindfulness. But often we don’t even consider the air inside our home may be highly polluted. We often don’t realise that our home may contain toxic air. One way we can improve this is to grow indoor house plants for a healthy home.





Building Biology  is a holistic discipline which examines and identifies irritants and hazards in residential and public structures. These include building materials, the products we use, air quality, water, biological contaminants (mould) and pest control, as well as electromagnetic fields (EMF’s) radiation (EMR) and geopathic stress.

It developed in response to a growing awareness of the impact toxic components in our immediate environment are having on our health. According to Building Biologist Nicole Biljsma  it “provides a holistic examination of the built environment and provides realistic solutions to create buildings that support mind, body and soul.”

When problems with the air quality within buildings are found the first line of attack is to eliminate the source of pollution. Pollution may be caused by building materials, furnishings, products used within the space, pest control, or cleaning methods.

Once the source of the pollution has been addressed the next step to achieve clean air is to install air purifiers and filters.





Before you buy an expensive electric air purifier for your home, consider that bringing in household plants is one very simple way to improve air quality in your home.

It’s said plants are the lungs and kidneys of the building. Research at NASA’s Space Centre has shown the presence of certain indoor plants actually improves indoor air quality.

The plants are able to grab and filter common pollutants found indoors and therefore purify the air.

NASA has made a list of the most beneficial plants in order of their effectiveness.





Many of the products including carpet, fabric, wall coverings, furniture, and paints that furnish our homes, schools and workplaces contain highly toxic chemicals. These are released into the air, creating indoor air pollution.

In 2009 the US Environmental Protection Agency stated “The air within our homes can be seriously more polluted than the outdoor air in even the largest and most industrialised cities”.

Many newer homes are designed to intentionally ‘seal in’ the air. This is done to better regulate the internal environment and reduce the use of carbon fuels for heating and cooling.

Living in these sealed homes can result in a disorder know as Sick Building Syndrome.

Sick Building Syndrome is a recognised disorder which results from the build up of toxins in our environment. One in particular is formaldehyde.

It’s becoming more widespread with the increase of energy efficient buildings. These sealed buildings allow little exchange of fresh outdoor air for the stale polluted indoor air. This lads to the indoor air becoming ten times more polluted than the air outside. In developed societies we spend up to 90% of our time indoors. Therefore we are now spending most of our life in extremely toxic surroundings. Indoor air quality is quickly becoming a particularly concerning problem.

Simply introducing plants into the environment can greatly reduce these problems.

Research from the Environmental Research Laboratory of John C. Stennis Space Center has shown that rooms filled with the right plants have 50-60% fewer airborne moulds and bacteria than those without plants.

You know that plants take in carbon dioxide and release oxygen. But it appears the plants can also suck toxic chemicals out of the air by absorbing the pollutants into their leaves. Then they transport them to the roots where they are transformed into food.

NASA findings show that plants are able to remove up to 87% of air toxins over 24 hours.





Indoor plants can bring a host of physical and mental health benefits.

Houseplants purify the air in a number of ways.

The air in environments that use ducted heating dries out quickly, causing respiratory congestion and dry skin. Plants are ideal additions in these places as they balance humidity levels by maintaining the moisture levels in the air at an optimum level. This is low enough to reduce illness and at the same time, high enough to prevent mould formation

The Norwegian University of Agriculture found that indoor plants fight certain illnesses. With indoor plants the symptoms of these health problems reduced.

  • Fatigue by 20%
  • Headache by 45%
  • Sore/dry throat by30%
  • Coughs by 40%
  • Dry facial skin by 25%

Other research has shown house plants have a psychological benefit. They increase self-esteem, improve mood, reduce stress, anxiety and depression and increase feelings of calm, relaxation and optimism.

With their ability to impact stress levels and reduce blood pressure levels, the important role of indoor plants in a society with a rising incidence of Adrenal Fatigue seems apparent.

Being surrounded by indoor plants can also make you think better. Indoor plants improve memory, concentration and attention, as well as boost creativity. Perhaps bringing one into you study or office will improve your productivity as well as reduce the EMR from your computer.
