Speaking of masks
Can Wearing a Mask Reduce My Allergy Symptoms?
While cloth and medical masks do a good job of protecting us from viral particles, studies show masks also can be effective at filtering common allergens, which typically float around in much larger sizes, making them easier to block. Pine tree pollen, for example, is about 800 times larger than the coronavirus, said Dr. David Lang, an allergist at Cleveland Clinic. Even before the pandemic, he advised patients with severe allergies to wear a mask outside, especially for prolonged activities like gardening or yardwork.
Using masks to alleviate allergy symptoms can require a bit of “trial and error,” said Dr. Purvi Parikh, an allergist and immunologist at N.Y.U. Langone Health. But over all, “if there’s less pollen going into your nose and mouth, you’re less likely to have an allergy attack,” she said.Although the findings suggest that wearing a mask can reduce allergy symptoms for some people, the researchers noted that more study is needed. It could be that the nurses experienced fewer symptoms because, when they weren’t working, they were staying home and avoiding crowds during lockdowns, and thus had less exposure to allergens in the environment. But the fact that mask wearing, which covers the nose and mouth, was associated with improvements in nasal symptoms, but not eye irritation, suggests that masking probably did help reduce many allergy symptoms.
In addition to filtering out allergens, wearing a mask also makes the air in our nasal cavities warmer and more humid, said Dr. Dror. “We know that dry air and cold air sometimes has the ability to elicit a reaction in the nose,” he said. “This is an extra benefit of wearing a mask. With all the bad, you can find some good.”
