Does Indoor Air Quality Affect Your Health?

The relationship of indoor air quality and health have  been the subject of much attention.  Although serious health-related problems are possible,  there is a common perception that poor indoor air causes poor health.  But, most people are unaware that the causes and possible effects are not always completely understood.

Indoor air quality is good when it is odor and dust free, has adequate air movement and has a comfortable temperature and humidity. When indoor air quality (IAQ) is poor, most health-related complaints may mimic cold or flu-like symptoms such as headaches, sinus problems, nausea, fatigue or irritation of the eyes, nose or throat.
Potential sources of contaminants in office buildings include cleaning supplies, pesticides, new building materials, furnishings, dusts, cosmetics, molds, mildew and human by-products such as carbon dioxide, dander, perspiration and food or  garbage not disposed of in an appropriate and frequent manner. Almost all of these are present in a building environment to some degree and only become magnified when concentrations become excessive.
Poor indoor air quality often occurs when ventilation is inadequate to keep contaminant concentrations at acceptable levels.  The heating, ventilation, and air condition system should not only control contaminants, but must also provide a comfortable environment. The perception of unmoving or stale air, odor, draftiness or exorbitant temperature and humidity can lead to discomfort and the beginning of an indoor air quality complaint.
