Hydrogen Intake Relieves Alcohol Consumption and Hangover Symptoms in Healthy Adults: a Randomized and Placebo-Controlled Crossover Study

BACKGROUND: Alcohol-induced hangover represents a significant, yet understudied, global hazard and a large socio-economic burden.

OBJECTIVES: The aim of this study was to investigate the effects of hydrogen (H2) on relieving drinking and hangover symptoms in 20 healthy volunteers. METHODS: In this pilot, randomized, double-blinded, placebo-controlled, matched, crossover interventional trial, participants were matched into pairs and randomly assigned. Study group 1 inhaled placebo air for 1 hr, followed by drinking 100 ml of liquor (40% alcohol) within 10 min, and then pure water. Study group 2 inhaled a mixture of H2 and O2 gas for 1 hr, followed by drinking 100 ml of liquor within 10 min, and then H2 dissolved in water. On a second intervention day (crossover) >/=1 wk later, study-group subjects were switched to the opposite order. Breath alcohol concentration (BrAC), hangover severity, and cognitive scores were measured.

RESULTS: The BrACs within the H2 group were significantly lower than those within the placebo group after 30 min, 60 min, and 90 min (P < 0.05). The H2 group reported having fewer hangover symptoms compared with the placebo group (Placebo: 77% of symptoms absent, 19.7% of mild symptoms, 2.7% of moderate symptoms, 0.7% of severe symptoms; H2: 88.6% of symptoms absent, 10% of mild symptoms, 1.3% of moderate symptoms, 0% of severe symptoms; P < 0.001). H2 treatment improved cognitive testing scores (P < 0.05), including attention and executive functions. Furthermore, consumption of H2 was negatively (beta = -13.016; 95% CI: -17.726, -8.305; P < 0.001) and female sex was positively (beta = 22.611; 95% CI: 16.226, 28.997; P < 0.001) correlated with increased BrACs. Likewise, the consumption of H2 was negatively (OR: 0.035; 95% CI: 0.007, 0.168; P < 0.001) while female sex was positively (OR: 28.838; 95% CI: 5.961, 139.506; P < 0.001) correlated with the severity of hangover symptoms.

CONCLUSIONS: H2 decreases BrACs and relieves the symptoms of hangovers.This trial was registered at China Clinical Trial Registry as ChiCTR2200059988. URL of registration: http://www.chictr.org.cn/showproj.aspx?proj=58359.
