Air-quality becomes a health factor as soon as it’s inhaled. Think of breathing as just another form of eating. Our lungs, like our stomach, are the principle organs used to ‘digest’ the air we breathe and feed our bloodstream. Air-quality, like nutrition, directly impacts our health status, acute and chronic decease severity, and successful pathology prevention efforts. An estimated 4.2 million premature deaths globally are linked to ambient air pollution, mainly from heart disease, stroke, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections in children. Pollutants with the strongest evidence for public health concern, include particulate matter (PM), ozone (O3), nitrogen dioxide (NO2) and Sulfur dioxide (SO2).
The health risks associated with smaller particulate matter are especially well documented. These are capable of penetrating deep into lung passageways and entering the bloodstream causing cardiovascular, cerebrovascular and respiratory impacts. The Health Guardian follows formal decision-making practices to maintain a healthy environment of ambient air in which we live, exercise, and work. Environmental factors impacting air-purity include outgassing of soils and water, crops and other vegetation, man-made materials (such as buildings and cars), farm and domestic animals, wildlife, and climate. Air-purity does not recognize boundaries. Thus, air particulates and toxic gases originating in one home, place of work, city, state, or nation routinely drift to other regions, worsening existing air quality problems. A problem in managing air quality is that unlike the food groups, generally we cannot see air. For example, gaseous pollution is usually invisible, and fine particulate air pollution is much too small to see with the unaided eye. Indoor air quality such as found in offices, factories, homes, schools, and hospitals can even be more of a concern. Many people spend most of their time indoors, and indoor air quality can be an even greater concern than outdoor air.
