1. Dust mites - these little microscopic critters live in your bedding, and their feces are a major contributor to asthma episodes. Use dust mite covers on pillows, mattress, duvet covers.
2. Dietary - the most common dietary allergens are dairy, soy, eggs, wheat, peanuts, tree nuts, fish and shellfish. If you have asthma, try eliminating these from your diet for a few weeks to see if you notice any improvement. Then, introduce one ingredient at a time back into your diet, and wait a few days (4 to 5 days) to see if you have any reaction before re-introducing another single item.

3. Mold, pollens, and pet dander are common environmental allergens that can trigger or worsen asthma.
4. Second-hand cigarette smoke - actually worse than first-hand, especially for the delicate respiratory system of children. If you smoke, please be sure to only smoke in areas that aren't shared by others.
5. Run a HEPA-filter in bedroom at night and in any other household room(s) that one spends a lot of time in.
