Indoor Air Quality

People are supposed to inhale clean air to lead healthy life. A lack of ventilation indoors concentrates air pollution where people often spend the majority of their time. Indoor pollution fatalities may be caused by using pesticides and other chemical sprays indoors without proper ventilation. Worldwide more deaths per year are linked to polluted air  than to automobile accidents.Direct causes of air pollution related deaths include aggravated asthma, bronchitis, emphysema, lung and heart diseases, and respiratory allergies.The health effects caused by Indoor Air Quality may range from subtle biochemical and physiological changes to difficulty in breathing, wheezing, coughing and aggravation of existing respiratory and cardiac conditions. These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and premature death. The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, the individual's health status and genetics.
