If you’ve ever found yourself mid-sneeze spiral during allergy season, this might be the most unexpected piece of good news: Matcha might help.
A new study published in NPJScience of Food suggests that matcha may reduce sneezing, but not in the way most allergy treatments work. Instead of targeting inflammation or histamines, researchers found that matcha appears to act on the nervous system, specifically the reflex that triggers sneezing.
Researchers exposed mice to allergens that would normally trigger symptoms similar to hay fever, including repeated sneezing. One group was given matcha, while another was not. The result was pretty clear: The mice that consumed matcha sneezed significantly less.
But the more interesting part is why. Most allergy treatments focus on suppressing the immune response, essentially stopping your body from overreacting to pollen, dust, or whatever is triggering your symptoms. Matcha didn’t really do that. The study found that it didn’t meaningfully reduce the underlying allergic reaction itself.
Instead, it seemed to interfere with the brain’s sneeze reflex.
Matcha reduced activity in a part of the brainstem that controls involuntary responses like sneezing. So rather than preventing the allergy, it may be preventing your body from reacting to it as aggressively. It’s less about fixing the problem and more about turning down the volume.
As for what’s actually in matcha that could be causing this effect, researchers point to its high concentration of bioactive compounds, like amino acids (including L-theanine), which have already been linked to anti-inflammatory and calming properties. The exact compound responsible for this effect hasn’t been isolated yet, but the working theory is that it influences how sensory signals are processed between the nose and the brain.
Before you start treating your seasonal allergies with iced matcha lattes, there are a few important caveats.
This study was conducted in mice, not humans, and the amount of matcha used was much higher than what you’d typically consume in a standard drink. Researchers are clear that more studies, especially in humans, are needed before this becomes an official recommendation.
Still, it points to something interesting: Food and beverage ingredients affecting not just how our bodies react, but how our brains interpret those reactions.
At the very least, it adds another layer to matcha’s already long list of supposed benefits.
Best-case scenario, your daily matcha might be doing a little more than just giving you a steady caffeine boost. Worst case, you’re still sneezing, but now you have something to sip while you deal with it.
