The mechanisms behind this upregulation appear to involve: Activation of the Nrf2 pathway, which controls the expression of various antioxidant enzymes including GR Modulation of cellular signaling cascades that respond to redox status Alteration of mitochondrial metabolism, influencing NADPH availability for GR activity Reduction of inflammatory signaling that can suppress antioxidant enzyme expression These effects suggest that hydrogen water may provide a "hormetic" stimulusa mild oxidative challenge that triggers beneficial adaptive responses in cellular antioxidant systems
Animal studies also demonstrate its ability to reduce seizure threshold, alleviate depression-like behaviors, and modulate dopaminergic and serotonergic systemseven showing synergy with antidepressants and anxiolytics in preclinical models

That means conclusions about people cannot be drawn from animal data, and any claims of proven human benefit would be getting ahead of the science
