Scientists predict allergy season will get even worse, thanks to climate change

Scientists say climate change has already made allergy season longer and pollen counts higher, but there’s new evidence it will get even worse.

That’s bad news for those living with seasonal allergies. If you have allergies, you probably suffer in early spring.

And to make matters worse, climate change will make allergy season even more unpleasant, according to a new study published in the Journal Nature Communications.

Climate scientists at the University of Michigan looked at 15 different plant pollens in the U.S. and used computer simulations to calculate how much worse allergy season will likely get by the year 2100.

They found it’ll start weeks earlier, end several days later, and be worse while it lasts.

Those scientists say warmer weather allows plants to bloom earlier and keeps them blooming later. Additional carbon dioxide in the air from burning fuels helps plants produce more pollen.

The Southeast is predicted to be hit the hardest.

“I love to be outside,” said Yuwan Harper. “That puts a damper on me being out as often.”

The changes are already happening.

Allergists say pollen season in the U.S. used to start around Saint Patrick’s Day but now, it often starts around Valentine’s Day.

So what can you do to manage your symptoms?

The Mayo Clinic suggests the following:

  • Reduce your exposure to allergy triggers -- For example, stay indoors on dry, windy days, or delegate lawn mowing.
  • Keep your indoor air clean -- Use things like air conditioning and a dehumidifier in your house.
  • Try over-the-counter medications.
  • If your symptoms are still unbearable, see your doctor.
