Chronic inflammation is a silent, pervasive driver behind many of today's most challenging health conditions. Unlike the acute, beneficial inflammation that helps heal a cut or fight an infection, chronic inflammation is a lowgrade, persistent state where the body's immune response remains activated unnecessarily. This ongoing biological fire can damage healthy cells, tissues, and organs over time, contributing to a vast array of diseases from arthritis and diabetes to cardiovascular issues and neurodegenerative disorders. In the search for safe and effective ways to modulate this complex process, molecular hydrogen, specifically administered via hydrogen gas inhalation, has emerged as a compelling area of scientific interest. This article delves into the mechanisms, potential benefits, and current understanding of using hydrogen gas as a therapeutic approach for managing chronic inflammation.
