Friday marked the first day of spring which means allergies are on the way for millions. Those hoping for some relief from allergies this season may not be in luck. Recent studies suggest that this season could be particularly grueling.

Studies show that approximately 35 million Americans are affected by allergies and those effects range from mild to severe. This year, the trees are “primed for a heavy pollen season,” according to allergy specialist at Brigham and Women’s Hospital Dr. Tanya Laidlaw, so that number is not expected to drop.

Laidlaw said that symptoms “might actually be more severe.” She added that the U.S. suffered an unusually wet winter with record-setting snowfall that could add to the severity of allergies this season.

The good news is that this allergy season could be a bit shorter. Laidlaw said that the oak, classic maple and birch that are responsible for several spring allergy symptoms “will be pollinating later than usual.” She added that because of this, the season could be “a few days to a week” shorter.

Laidlaw says that taking preventive actions is better than waiting until symptoms surface. She recommends allergy-sufferers to start taking medications a few days to a week prior to the onset of pollen season.

Dr. James Sublett, president of the American College of Allergy, Asthma and Immunology, said in a college press release that “knowing what triggers your symptoms” is the key to having a “sneeze-free” allergy season, according to U.S. News and World Report.

The release also offered some tips for handling allergies.

Avoid synthetic fabrics and opt for natural fibers, like cotton, that stay drier and are less likely to harbor mold. Also, exercise outdoors in the late afternoon or early evening when pollen counts are lowest. Additionally, simply leave shoes by the door, shower often, use a dehumidifier and vaccuum furniture.
