Pollen Levels

Many people suffer from bothersome allergy symptoms when pollen levels are on the rise. The types of pollen that cause most allergy symptoms are produced by grass, weeds and trees. Pollen levels are determined by the amount of pollen in the air and are higher at certain times of the year.

Identification

• Pollen is a microscopic substance produced by plants in order to reproduce. Falling pollen becomes airborne and travels great distances. According to the American Academy of Allergy Asthma and Immunology, pollen levels are measured by the National Allergy Bureau.

Function

• Measuring pollen levels requires a pollen sample. Pollen samples are collected using air sampling devices which trap pollen on a sticky surface. Experts determine the pollen level for the day by counting the pollen grains under a microscope.

Effects

• Measuring pollen levels and predicting future pollen levels is important for allergy sufferers. Avoiding exposure to pollen is the best course of action for those who suffer from allergies. Measuring the levels of pollen in the air helps those with allergies plan their day and their activities. According to Achoo Allergy, those who suffer from allergies should limit their outdoor activities when the pollen counts are high to reduce allergy symptoms.
