It's spring allergy season. Allergies are caused by an immunologic reaction triggered by allergens, substances like pollen and mold, to which a person is sensitive.
Weather conditions affect the amount of pollen and mold spores in the air.
Allergy symptoms are often minimal on rainy, cloudy or windless days, while hot, dry and windy weather can increase allergy symptoms. Keep windows closed at night to prevent pollens and molds from drifting into your home. Instead, if needed, use air conditioning which cleans, cools and dries the air. Minimize activities when pollen counts are high. Peak pollen times are usually between 2-4 p.m. 3.
