Clean air is essential for good health, and this is especially true when it comes to indoor air.
As Canadians, we spend close to 90% of our time inside; at home, at work and in recreational environments. Most people, however, are unaware of the effects that poor indoor air quality can have on their health.
All of us have the ability to control the quality of our own indoor air. Do you have mould in your home? Is the air in your home really healthy?
Biological pollutants are living organisms like mould, bacteria and dust mites. Chemical pollutants are gases and particles that come from combustion appliances, tobacco smoke, household and personal care products, various building materials and outdoor air. A lack of ventilation, especially in air-tight buildings, is a key factor that impacts the quality of indoor air.
It is well known that poor indoor air quality increases the severity and the frequency of respiratory symptoms experienced by asthmatics. Pollutants that can aggravate asthma include the following:
Biological pollutants such as mould and house dust mites.
Irritating chemical pollutants such as nitrogen dioxide, ozone and formaldehyde.
Dust mites are the only indoor air pollutants that are recognized to cause asthma in otherwise healthy people. Other pollutants such as mould and nitrogen dioxide, however, are suspected of increasing the risk of developing asthma. With this in mind, it is therefore advisable to avoid exposure to these pollutants as much as possible, even if you are not asthmatic.
