In Wausau, Wisconsin, Dr Virginia McKenna of Sanford Health Marshfield Clinic said tree pollen typically peaks from April to early June before grass and ragweed seasons follow.
Symptoms include itchy eyes, runny nose, congestion and sore throat, caused when inhaled pollen triggers mast cells to release histamine; over-the-counter medicines such as Claritin or Allegra can help.
Doctors advise closing windows on high-pollen days, showering after being outside, checking forecasts, limiting outdoor time when counts are highest and seeking medical care if symptoms persist.
