Beware of the Air
Breathing polluted air can worsen symptoms. In fact, airborne toxins can actually cause allergies in some people. If you suspect that air pollution triggers your attacks, spend as little time outdoors as possible on smoggy days. When you must go outside, wear a surgical mask, especially while exercising. Don't expect miracles (the mask won't screen out all allergens) but it may help you breathe a little easier.
Tobacco smoke is a notorious irritant, either causing or aggravating respiratory allergies. Don't let your friends and family foul the air with cigarettes, cigars, or pipes. And, of course, if you still light up, stop it!
A fresh breeze blowing through an open window on a spring day may sound inviting, but it's bad news for an allergy sufferer, since it can fill the house with pollen. To minimize contact with the powdery stuff, keep windows closed at all times. Air purifiers, especially those with HEPA (High Efficiency Particulate Air Filters) filters, may help eliminate indoor pollen, but they also tend to stir up dust, which might worsen some allergies.
On a windy day in pollen season, a pair of sunglasses (or your regular prescription eyeglasses, if you wear them) may also help shield your eyes from airborne allergens. For extra protection, try a pair of sunglasses with side shields or even a pair of goggles.
