Ok… For beginners let me give you a prehistoric example 🙂 Have you noticed that the inner surface of prehistoric caves were covered with soot. Well this must have come because of cooking fire or from a fire to keep our ancestors warm. The smoke might be a cause of some degree of health risk in them. This smoke which is confined to a particular enclosed area can cause internal air pollution.

Smoke from our cooking might not affect us in this age of technology. But there are much more harmful contaminants floating in the air inside our modern dwellings too. According to one study it can be up to 10 times worse than the air outside.

The awareness over this kind of pollution has been recent, over past three decades, to say. Many studies have shown that people spend 65 to 90 percent of their time indoors; 65 percent of that time is spent at home.

Causes of this kind of pollution vary from microbial pollutants like mold, pet dander and plant pollen to chemicals like radon and volatile organic compounds (VOCs). Even things used for building materials and the kind of furniture, paint used on the walls also play an important role in determining the kind of internal air we breathe in. Indoor air pollution is easy to manage if you know where it comes from.

Not having proper ventilation helps promote mold and other microbial growth, especially in rainy season (monsoon); mold colonies can propagate on any material like wood or paper and release spores which can cause allergy. As such, a basic way of maintaining the health of indoor air is by letting the outdoor air in by opening the windows.

Strategies to keep internal air clean and fresh:

  • get good ventilation
  • use cleaning solutions which are free from harmful chemicals
  • avoid pesticides for your plants
  • keep air filters clean

So please keep your indoors clean, green and fresh. Take care of your health.
