Spring allergy season is starting in many U.S. regions

Allergy season often begins in March in many parts of the United States, and experts in the article say preparing ahead can reduce peak symptoms as trees and grasses release pollen.

Allergy season often begins in March in many parts of the United States. Warmer weather prompts trees, grasses and weeds to release pollen that can cause congestion, sore throat or itchy eyes for many people. Studies cited in the article report that pollen seasons are lengthening with a warming climate. The article conveys expert views that preparing before symptoms peak can reduce the overall burden. Key points: - Seasonal timing: Pollen tends to arrive in three waves—tree pollen from late winter into spring, grass pollen from late spring into summer, and weed pollen from late summer into fall—and timings vary by region. - Medications and timing: The article reports that some experts say second-generation oral antihistamines and nasal steroid sprays are commonly used, and that some clinicians suggest starting them before a local pollen peak; longer-term use of topical decongestants was noted as a concern. - Home and supplies: Experts mentioned steps such as limiting pollen entry by closing windows near the start of the season, checking HVAC and air-purifier filters on regular schedules, designating space for pollen-coated outerwear, and having items like saline sprays and masks available. - Overall health and asthma: The article notes that controlling asthma and maintaining general health markers—sleep, hydration, exercise and skin moisture—was reported as helpful for reducing inflammation and symptom sensitivity; inhaler use around outdoor exposures was described as an option for some people with asthma. Summary: Pollen seasons affect many people each year and may exert greater impact as their length increases with climate trends. The article cites local pollen forecasts and clinical guidance as ways to understand timing and options, and specific recommendations were reported to vary by individual and region.
