Do you blame the pollen count for your coughing, sneezing and stuffy nose? Do you track the pollen count and stay indoors on heavy pollen days? I hate to tell you, but the quality of air inside of buildings, where people spend about 90 percent of their time, is even more important to your health. Ironically, according to the EPA, indoor air can be two to five times more polluted—and in some cases up to 100 times more polluted—than outdoor air. This is a significant issue in schools, where exposure to allergens, such as dust mites, pests and molds can trigger asthma symptoms.
