Spring kicks off this month, and with it come seasonal allergies for millions of Americans.
According to the Centers for Disease Control and Prevention, about 25% of adults and nearly 21% of children in the U.S. have a seasonal allergy.
The CDC notes that climate change can impact the length and severity of allergy season.
Research by Climate Central found that “climate change contributes to earlier, longer, worse allergy seasons for millions in the U.S. that suffer from seasonal allergies to pollen — including about one in every five children.”
The climate research nonprofit additionally found that “87% (172) of 198 U.S. cities analyzed since 1970” have experienced an increase in freeze-free days each year, giving plants more time to grow and release pollen.
“Research has definitely shown that the seasons are indeed expanding,” Dr. William Reisacher, an otolaryngic allergist with Weill Cornell Medicine and New York-Presbyterian Hospital, told ABC News previously. “We’re seeing longer pollinating seasons. We’re seeing higher levels of pollen.”
ABC News chief medical correspondent Dr. Tara Narula shared tips for allergy season, saying that one of the key ways to get ahead is to prepare at least two weeks before the onset of symptoms and discuss preparations with your doctor or an allergist, as well as check pollen counts regularly.
At home, Narula recommends taking these steps:
– Use HEPA filters
– Keep doors and windows closed on high pollen days to reduce the spread of pollen.
– Take showers and wash clothes after being outside. Wash bedding regularly.
– Use N95 masks during peak pollen periods.
– Wear a hat and sunglasses outside.
If allergy symptoms persist after two to four weeks, Narula suggests consulting with your doctor and considering prescription medications.
