Spring brings millions of Americans suffering from allergies. Understanding when different types of pollen reach their highest levels can help manage symptoms effectively.
Tree pollen peaks in late winter to early spring, typically between February and May, depending on location. Warm, dry days exacerbate levels, while rainy days clear the air. Common culprits include oak, maple, birch, cedar, and pine trees.
Grass pollen takes over from late spring to early summer, peaking in April and June. Bermuda, ryegrass, Timothy, and Kentucky bluegrass are common offenders on warm, breezy afternoons.
Ragweed pollen is most notorious in late summer and fall, with peak levels between August and November. Researchers suggest going outside during the low-pollen hours (4:00 a.m. to noon) and limiting outdoor activities between 2:00 p.m. and 9:00 p.m. for relief.
Staying informed about peak pollen behavior through websites and apps can help plan accordingly and reduce symptoms. By taking preventive measures, allergy sufferers can better navigate the season with fewer flare-ups.
