Indoor Environment have to do with • All of the common asthma triggers are found indoors • Americans spend about 90% time indoors • Reducing exposure to indoor allergens and irritants can reduce asthma symptoms • Prevention is an important asthma management tool EPA Indoor Environments Division, Jan 2001, Slide 12

  13. Indoor Environmental Triggers Most common Secondhand Smoke Dust Mites Mold Pets Cockroaches EPA Indoor Environments Division, Jan 2001, Slide 13

  14. Smoke Secondhand • Contains more than 4,000 substances (over 40 are carcinogenic) • Is particularly harmful to young children • Can trigger asthma attacks and cause young children to develop asthma EPA Indoor Environments Division, Jan 2001, Slide 14

Avoiding Triggers dust mite • Wash sheets and blankets once a week in hot water • Choose washable stuffed toys, wash them often in hot water, and dry thoroughly -- keep stuffed toys off beds • Cover mattresses and pillows in dust-proof (allergen-impermeable) zippered covers • Vacuum often (when asthmatic is not present) • Maintain low indoor humidity, ideally between 30-50%  EPA Indoor Environments Division, Jan 2001, Slide 17
