Indoor Air Quality - A Growing Concern?
People spend 90% of
their time indoors and indoor pollutant levels are consistently higher
(2 to 5 times) than outdoors. Breathing poor indoor air may have a negative impact on one's health. Therefore, people who spend much of
their time indoors may be at greater risk of developing health problems
or having problems made worse by indoor pollutants.
Persons most
affected include infants, young children, the elderly and those with
chronic illnesses.
Health effects from poor indoor air are predominantly observed in children with asthma. In the last 15 years, there has been a 60% increase in incidence of asthma in school-aged children. Today, 8% of all school-aged children have been diagnosed with asthma and it has been estimated that 2.6 million children under the age of 15 have asthma.
Everyone is exposed daily to biological pollutants. However, the effects on our health are dependent upon the air pollutant, concentration, duration of exposure and individual sensitivity to the irritant. Some persons do not experience health reactions from biological pollutants, while others may experience one or more of the following allergic reactions:
Some Common Signs & Symptoms:
Watery Eyes

Nasal congestion
Itching
