It's not necessarily the trees causing your bad allergies

It is a complicated process to know all about allergy causes and treatments. Typical allergy causes like pollen from trees and grasses aren't the only items that might have you reaching for the tissues.

It's a right of passage as in tune with the seasons as the swallows returning to Capistrano: as the trees bloom and a thin veil of pollen cover the cars, allergy sufferers serenade the world with sneezes and calls to the doctor for antihistamines.

These allergy patients may believe that it's the trees and the season that's causing their symptoms, but for many the problem may not be outside. It might be right under their bed.

Allergy patients are often sensitive to a number of allergens, and allergy symptoms emerge only when cumulative exposure to these allergens pushes them over the symptom threshold. As long as the cumulative exposure is below threshold, allergy symptoms are not present. But once the threshold is breached all hell breaks loose.

For example, a patient may be sensitive to three allergens, such as pet dander, dust mites, and pollen. For 11 months of the year, the cumulative load of the pet dander and house dust mites is just below the threshold. No symptoms. But that one month when pollen is in the air, the patient is over the threshold and symptoms are unmanageable. As a result, a patient suffering from terrible allergic symptoms during pollen season may be able to avoid these symptoms by targeting and reducing their exposure to other allergens, in short, rendering their sensitivity to pollens less than harmful.
