TL;DR
Hydrogen gas may protect cells and tissues from the damaging effects of radiation.
Key Finding
Hydrogen treatment before radiation exposure significantly reduced cell death and increased cell survival in laboratory tests, and protected the gastrointestinal tract from radiation-induced injury in mice.
Summary
Researchers tested whether hydrogen could protect cells and mice from damage caused by radiation exposure. They found that hydrogen reduced harmful molecules called hydroxyl radicals that are created when cells are exposed to radiation. In lab tests, hydrogen treatment before radiation exposure helped cells survive better and reduced cell death. In mice, hydrogen also protected the digestive tract from radiation damage and boosted the body's natural antioxidant defenses (molecules that fight cellular damage).
Practical Takeaway
This early-stage research in cells and animals suggests hydrogen may help protect against radiation damage by neutralizing harmful molecules, but human studies are needed to determine if these findings apply to people. The study does not yet provide evidence that hydrogen water would be effective as a radioprotective agent in real-world situations.
Abstract (excerpt)
It has been demonstrated that hydrogen can selectively reduce hydroxyl and peroxynitrite in vitro. Since most of the ionizing radiation-induced cellular damage is caused by hydroxyl radicals, this study was designed to test the hypothesis that hydrogen may be an effective radioprotective agent…
