The EPA in its report discusses how the Indoor air quality causes discomfort to people. Indoor air quality is seen to decrease because of tobacco smoke, household products such as asbestos and more (Medline Plus, 2014). People living in such indoor air might be affected with allergies or might suffer wheezing and other symptoms. In addition a person who already has allergies might feel that the indoor air is actually causing them to feel sicker. This could be because of physiological reasons or it could be because of psychological reasons, either way there is a deterrent to good health because of the air quality (Graudenz et al, 2006). Sometimes people of a building fall sick at the same time, this is called the sick building syndrome. Some of the causes of this sick building syndrome are that of having inadequate ventilation where the building standards are not met and the HVAC system is inadequate. There can be chemical contaminants present from other indoor sources and chemical or biological components from outdoor sources could also be present (EPA, 1991). While some people might feel better when they move out of their homes, others might experience worsening symptoms. Symptoms such as allergic reactions, wheezing or shortness of breath might be cured by treating the symptom, but the accumulation of ill health from the pollutants that are present in the building could cause problems later on. Chronic wheezing or asthma could lead to lung damage and makes the person susceptible to secondary infections like that of pneumonia, tachycardia because of increased heart output among others (Shamblin, et al, 2012).
