Diagnosing asthma or allergies usually involves a complete patient study including a thorough history of the illness, family medical history, evaluation of home and work environments, and allergy testing. Based on the results, asthma and allergies can be managed with medications and lifestyle changes that will ease the symptoms. In Maryland, May and June are the peak pollen season for trees such as oak, maple, pine and hickory, as well as for many grasses and weeds. When the weather is warm and breezy, tiny pollen grains are easily carried in the air. Limit outdoor activities to later in the day, when pollen counts are lower.
Pollen counts are also low on rainy days, when humidity is high and when temperatures are cool.
Keep windows closed during peak allergy season so pollen spores don't blow into your home. Wear a lightweight face mask while doing yardwork. Drive with car windows closed. Always shower and shampoo your hair to wash away pollen after spending time outdoors. Don't hang sheets outside to dry.
