When working in the yard, wear a mask over the nose and mouth to block out at least some of the environmental irritants. At work and in social settings, try to avoid cigarette smoke as much as possible. Many employers now have have no-smoking policies. The same is true for pollution index or air quality reports. To the extent possible, limit trips outside on days when the pollen count is high or the air quality is reduced as a result of auto exhaust, industrial pollution, smoke, or other environmental irritants.
Nasal allergies have a fairly strong association with climate and fluctuations in weather.
In other words, where you live influences your likelihood of developing allergies, as well as the frequency and severity of symptoms. As a general rule, allergies are more common in temperate areas that have mild weather much of the year, though the reason why is not entirely clear. The amount of rainfall an area receives also influences allergy symptoms. Rain washes irritants from the air, at least temporarily, giving many allergy sufferers a welcome respite from their symptoms. Allergies can be triggered by myriad factors, and no two people will have exactly the same type of sensitivity.
