Causes of Allergy

An allergy is a disorder of the immune system that causes symptoms, such as sneezing, itchy and watery eyes, and a runny nose. Allergens are the stimuli that cause these allergy-related symptoms. One of the most predominant allergies among the population is hay fever which causes allergic conjunctivitis and itchiness.

Environmental or dietary factors can cause reactions to allergens. The majority of people that have allergies react to airborne particles, such as dust or pollen.

How Weather Affects Allergy Forecast

Weather plays a direct role in the severity and length of the allergy season. Weather conditions will increase the amount of pollen production to yield high pollen levels or decrease pollen production to yield low pollen levels.

A mild winter can signify an early allergy season since trees tend to start pollinating earlier.
