Long-term spaceflight can lead to changes in eye structure and decreased visual function. At present, there are almost no effective methods to prevent and treat eye damage caused by microgravity environments. Oxidative stress has been identified as one of the contributing mechanisms of spaceflight-associated neuro-ocular syndrome (SANS), and hydrogen (H2) has demonstrated significant antioxidant and anti-inflammatory effects. The aim of …
Dual benefits of hydrogen gas inhalation and hydrogen-enriched dialysate
The combination of H₂ gas inhalation and H₂-enriched dialysate offers a novel and promising approach to managing oxidative stress and improving the quality of life in patients on HD. However, further research is essential to optimize treatment protocols, ensure safety, and develop comprehensive clinical guidelines for the widespread adoption of this therapy.

Hydrogen for skin autoimmune disorders
AGEs are molecules formed by nonenzymatic glycation of proteins, lipids, and nucleic acids, a process accelerated under hyperglycemic conditions such as DM1. These molecules interact with specific receptors, particularly the Receptor for AGEs (RAGE), triggering intracellular signaling cascades that promote oxidative stress through the generation of Reactive Oxygen Species (ROS) and activation of inflammatory pathways. A critical pathological mechanism involves …
Hydrogen-rich saline against hemorrhagic shock
The endothelial glycocalyx is a gel-like layer on the vascular endothelial surface that is crucial for maintaining vascular homeostasis. Massive bleeding leads to the shedding of the glycocalyx, which can lead to vascular leakage during fluid administration. Recently, the beneficial effect of hydrogen inhalation in the treatment of hemorrhagic shock has been reported. However, the efficacy of hydrogen-rich saline in …
Magnesium-assisted hydrogen for heart failure
Heart failure (HF) is a leading cause of mortality among patients with cardiovascular disease and is often associated with myocardial apoptosis and endoplasmic reticulum stress (ERS). While hydrogen has demonstrated potential in reducing oxidative stress and ERS, recent evidence suggests that magnesium may aid in hydrogen release within the body, further enhancing these protective effects. This study aimed to investigate …
Hydrogen water as useful mouthwash
Previous studies have demonstrated the inhibitory effect of hydrogen-rich water on biofilm formation. However, hydrogen-rich electrolyzed water (HEW) has not been evaluated as mouthwash, despite being economical, convenient, and biologically safe. We assessed the antibiofilm effects of HEW on Streptococcus mutans and its potential as a mouthwash. The effect of HEW on S. mutans growth was assessed by measuring bacterial …
Hydrogen for pemphigus-associated interstitial lung disease
Pemphigus-associated interstitial lung disease (P-ILD) is a severe complication observed in pemphigus patients that is characterized by pulmonary interstitial inflammation and fibrosis. This study investigated the role of anti-desmoglein (Dsg) 1/3 antibodies in P-ILD pathogenesis and evaluated the therapeutic potential of molecular hydrogen (H2). Using a BALB/cJGpt mouse model, we demonstrated that anti-Dsg 1 antibodies, but not anti-Dsg 3 antibodies, …
Hydrogen-rich water reduces muscle damage
Physical activity significantly increases the production of reactive oxygen species in the body. Molecular hydrogen has been shown to have safe and effective antioxidant properties on athletes. However, research on elite athletes is scarce. A randomized, double-blinded, placebo-controlled trial was conducted with 22 female elite athletes participating in handball and skeleton sports. The first group received hydrogen-rich water (HRW)-generating tablets, …
Hydrogen-rich water protects against encephalopathy
Hepatic encephalopathy (HE), a neuropsychiatric complication secondary to liver cirrhosis and hepatic failure, represents the leading cause of mortality in end-stage liver disease. While hyperammonemia remains the central pathogenic factor in HE progression, emerging evidence implicates oxidative stress, neuroinflammation, and neuronal apoptosis as critical synergistic contributors to HE pathogenesis. Hydrogen-rich water, known for its antioxidant, anti-inflammatory, and anti-apoptotic properties, has …
Hydrogen ameliorates steroid-associated osteonecrosis
Steroid-associated osteonecrosis (SAON) remains a challenging clinical condition as there are few effective preventive measures. This study investigates the effects of hydrogen (H2) administrated via saturated hydrogen-rich water (HRW) in mice received high dose of glucocorticoids (for inducing SAON model). Here we find that HRW treatment significantly reduces osteocyte apoptosis, improves deteriorated trabecular architecture, increases osteoblast numbers and the bone …
