TL;DR
Hydrogen-rich saline reduces allergy symptoms and inflammation in guinea pigs with allergic rhinitis by lowering oxidative stress and the activity of allergy-related cells.
Key Finding
Hydrogen-rich saline reduced sneezing and scratching frequency while decreasing eosinophil activation and oxidative stress markers in guinea pigs with allergic rhinitis.
Summary
Researchers tested whether hydrogen-rich saline could help reduce allergic rhinitis (hay fever-like symptoms) in guinea pigs. They found that hydrogen-rich saline reduced harmful molecules called reactive oxygen species, lowered sneezing and scratching, and decreased the number of immune cells (eosinophils) involved in allergic reactions in the nasal tissue.
Practical Takeaway
This early animal study suggests hydrogen may help reduce allergic inflammation by acting as an antioxidant, but these results are from guinea pigs only and have not been tested in humans. More research is needed before drawing conclusions about hydrogen water's effects on human allergies.
Abstract (excerpt)
Background: It is well considered that reactive oxygen species (ROS) plays a prominent causative role in the development of allergic rhinitis (AR), and eosinophils cells as important allergic inflammatory cells contribute to elevating oxidative stress. Hydrogen, emerging as a novel antioxidant, has…
