Breathe Easy: How Hydrogen Helps Fight Haze Pollution

A study found that hydrogen gas can protect the lungs of people exposed to haze pollution. Hydrogen acts as a shield, blocking harmful particles from entering the lungs and reducing free radicals that cause damage. You can use hydrogen to protect your lungs by making hydrogen water at home or inhaling hydrogen gas.

Methods

Results: (1)The FeNO levels of the treatment group (16±5)×109 were lower than those of the control group(21±14)×109 on 8th day of treatment, with significant difference(F=6.94, P<0.05). (2)The levels of FEV1 were significantly higher in participants from the treatment group as compared to the control group on both 8th [(96±13)% vs(94±14)%(F=3.96, P<0.05)] and 30th day [(97±14)% vs (95±12)%(F=8.5, P<0.05)] of treatment, while PEF was also increased on 15th day [(73±15)% vs(67±18)%(F=8.68, P<0.05)]. (3)The sputum levels of MMP-12 and SOD3 were consistently lower in the treatment group as compared to the control group at each time point, and the levels of IL-10 were higher in the treatment group as compared to the control group on the 15th and 30th day. MDA and IL-2 levels were lower in the treatment group than in the control group on the 30th day(P0.05). (4)The serum levels of IL-2 and SOD3 were lower in the treatment group as compared to the control group while IL-10 was higher than in the control group at each time point, and MMP-12 was lower in the treatment group than that in the control group on the 30th day(P0.05). (5)Hydrogen inhalation improved respiratory symptoms such as cough. Conclusions: Inhalation of hydrogen gas could alleviate airway inflammation and oxidative stress of sanitation workers exposed to air pollution. There was even a significant inhibitory effect on the level of systemic inflammatory response. Importantly, inhalation of hydrogen could improve respiratory symptoms such as cough.
