Allergy seasons in the U.S. are getting longer and stronger. Research suggests that climate change has something to do with it.

CGTN’s Joshua Cartwright explains.

The spring allergy season in the U.S. has been something to sneeze about for tens of millions of Americans.

Those who feel their symptoms have been particularly drawn out this year are on to something. Researchers have found that allergy seasons in America are lasting up to nearly a month longer than before.

As worldwide weather patterns change and temperatures rise, winters are getting warmer and wetter. That could be causing allergy seasons to start earlier and end later.

Higher pollen counts are also having an impact. According to the American Academy of Allergy, Asthma and Immunology, there’s been a first-time spike in the number of people experiencing symptoms.

The top five cities experiencing the worst symptoms this spring are all southern, ranging from Texas to Tennessee.

There are, however, ways to manage symptoms. Doctors recommend taking over the counter or prescription medication a few weeks before allergy seasons begin. Saline or medicated drops can help relieve red, itchy eyes, and showering before bed can mitigate morning allergies. If symptoms are severe, an allergist can come up with an individualized plan.
