In the past, people have been known to turn to singing Christmas songs in an effort to get rid of their allergies or for some other reason.
But now there are new ways to get your Christmas shopping done without using any bells or whistles.
According to a new study, people who sing Christmas carols without the aid of a group of professional singers are much less likely to become allergic to other Christmas carol tunes.
Researchers from the University of Washington found that people who practiced singing Christmas carolas without a choir had a 25 percent lower risk of developing an allergy compared to people who were able to sing the same songs without a group.
The study is the first to show that the singing of Christmas carorols without a vocalist reduces the risk of allergic reactions in people.
The study also looked at the effects of having a vocal voice on the immune system, including whether the vocalist’s presence influenced how quickly the immune response developed in the first place.
It also found that there was a statistically significant difference between people who sang with a choir and those who didn’t.
“We think it is likely that there are some mechanisms at work here, but we don’t know exactly how they work,” said study co-author Jennifer Witte, a professor of medicine and epidemiology at the UW.
She and her colleagues used data from more than 2,000 people in the U.S. who have been diagnosed with a life-threatening allergy to at least one Christmas song.
The people who participated in the study were able sing a range of Christmas songs, from the traditional Christmas Carols of the 18th and 19th centuries to contemporary hits, including The Walk, Sing Along, and The Little Drummer Boy.
The researchers looked at how well the participants sang each song and whether they were able and willing to perform the singing.
The researchers found that those who practiced non-instrumental singing in the carol context were less likely than others to become infected with an allergy.
However, the group who practiced a vocal performance, with the assistance of a professional singer, was less likely.
“If you practice singing without a voice, you have a more limited ability to reduce your risk of becoming allergic,” Witte said.
The results were published online by the Journal of Allergy and Clinical Immunology.
Other research has found that singing Christmas music without a singer can help people with chronic allergies to other seasonal sounds.
One study from 2016 found that using a voice-guided playlist to sing songs such as The Star-Spangled Banner, The Little Red Hen, and Santa Claus could help people who have a chronic allergy to the season’s holiday music.
