Pollen Forecast: April 9, 2008

Technical Discussion:
The amount of pollen in the air for Thursday will be higher than they were today and extend even further into the extremely high range. This increase is due to rising temperatures, strong winds and lower relative humidity.

Pollen and Allergy Fact:
In a large study of 20,000 adults in the United Kingdom, 20% thought they had a food allergy or intolerance. In a small subset of these patients who were tested with eight selected foods in a double-blind, placebo-controlled study, only 1.8% were actually allergic to the foods they predicted they would be.

Allergy Tip:
Set the car air conditioner to the recirculate setting to prevent new allergens from entering.

---Technical Discussion---The quantity of pollen grains in the air for Wednesday will be higher than they were today and extend further into the very high range. This higher level is caused in part by higher temperatures and the lower dewpoint.

Learn more about this month's featured pollen:

---Did You Know?---Pollen typically is released from a plant to eventually pollinate another plant, or land on the ground. However, pollen grains may become re-suspended into the air from their original resting places if weather conditions are right.
