TL;DR

Breathing or drinking hydrogen gas might help treat all kinds of diseases by reducing harmful inflammation and damage in your body. Scientists have already tested it on over 170 different conditions, and the results look promising enough that they want to do much bigger studies to see if it could become a real medical treatment!

Key Finding

Hydrogen has been studied in over 170 disease models across nearly every organ system, and clinical research is now emerging as a growing focus within hydrogen medicine.

Summary

This paper is a review article — meaning the authors gathered and summarized existing research rather than conducting a new experiment. It covers how hydrogen (H2) may work in the body, including its ability to reduce harmful oxidative stress (cell damage from unstable molecules), inflammation, and cell death. The review spans clinical studies across many disease types and organ systems, with the goal of guiding future large-scale human trials.

Practical Takeaway

This review suggests that hydrogen therapy is an active and expanding area of medical research, but it is a summary of existing studies — not new clinical trial data. Because large-scale, well-controlled human trials are still needed, it is too early to draw firm conclusions about hydrogen's effectiveness for any specific condition.

Abstract (excerpt)

H2 is a fundamental environmental factor for the origin of life, providing an energetic basis for the emergence of primitive life. Through its selective antioxidant, anti-inflammatory, and anti-apoptotic activities, as well as its regulatory effects on cell signaling pathways and gene expression…
