The Allergy-Asthma Connection
Putting Knowledge Into Action
- Control exposure to smoke—Do not smoke at all. But, if you must smoke, do so outside. Never smoke in a car that children ride in, even if your child is not in the car at the time. Wood smoke may also be an asthma risk; avoid wood heating. It may also be wise to assure that gas heaters and stoves are vented to the outside. These appliances produce combustion products that can irritate the lungs.
- Control exposure to pets—This is often debated as the evidence is inconsistent. In some studies, exposure to pets at a very young age was associated with less risk of allergies.
Control exposure to dust mites—Dust mites are microscopic creatures that are found in large quantities in your home. They tend to live in bedding, but are far too small to be seen. Strategies to reduce exposure to mites include:
- Wash all linens in hot water every seven days.
- Vacuum carpeting and upholstered furniture frequently using a vacuum cleaner with a “HEPA” filter.
- Keep indoor relative humidity below 50%.
