ASTHMA FACT SHEET: |
How can strong odors affect asthma?
Strong odors can irritate the airways in the lungs and trigger asthma symptoms for some people with asthma. This causes more days with asthma symptoms, such as coughing or wheezing, and can even lead to an asthma attack. Strong odors usually are from a gas, vapor, fume, smoke, or chemical that is inhaled.
Where are strong odors found indoors?
Many household products release strong odors that contain VOCs (volatile organic compounds) that can irritate the lungs. VOCs are found in cleaning products, cigarette smoke, fuel-burning appliances, pesticides, carpet/floor adhesives, car and furniture polishes, wood stains, solvent-based paints, solvents, caulks, adhesives, room deodorizers (particularly aerosol sprays), particleboard, and art/hobby supplies.
Many building materials and new furniture contain formaldehyde, a colorless pungent-smelling gas. Formaldehyde is found in cigarette smoke, carpet, plywood and pressed-board products and furniture, some foam insulations, cosmetics, and detergents. Formaldehyde is strongest when a product is new and will decrease over time.
Fragrances from cosmetics, perfumes, colognes, air fresheners and candles also may irritate the lungs. It is important to note that some fumes may not have strong odors, but can still irritate the airways in the lungs like nitrogen dioxide.
How can strong odors be controlled indoors?
- Use good exhaust ventilation when using products that release strong odors. If an exhaust fan is not available, open a window and use a fan to draw out fumes.
- Always use the exhaust fan above the stove while cooking, especially when frying.
- Choose cleaning supplies made with natural ingredients that are unscented, less hazardous or non-hazardous.
- Avoid using spray and aerosol cleaners.
- When making repairs/renovations use the least amount of supplies, such as caulks, solvents, paints, adhesives, and sealants, as necessary. If possible, use products with low VOC content. Use good exhaust ventilation.
- Do not perform repairs/renovations that may release strong odors or dust while people are present, or separate them from areas being renovated.
- Store products with strong odors away from living and play areas.
- Use non-toxic art/hobby supplies or choose products with the lowest VOC content available. Always use good exhaust ventilation.
- Limit air freshener and candle use.
- Avoid using cosmetics, perfumes and colognes with strong odors.
