Is hydrogen safe for the human body?

Long-term research shows that hydrogen is very safe for the human body, even if breathing tens of atmospheric pressure of hydrogen, although there will be some anesthetic effect, but the anesthetic effect is much smaller than nitrogen, will not cause toxic effects on the body, hydrogen biosecurity Higher than nitrogen, much higher than oxygen. So the use of hydrogen to treat the disease is a very reassuring means.
Hydrogen (hydrogen) is a chemical element, in the periodic table in the first position, the element symbol is H, is the smallest natural atoms. Hydrogen is usually a simple elemental form of hydrogen, hydrogen is colorless, odorless, odorless, easily combustible diatomic gas, hydrogen is the lightest gas, hydrogen thermal conductivity is particularly strong, hydrogen and oxygen to form water.
Shanghai Jiaotong University School of life science and technology vice president, doctoral tutor Professor Zhao Liping that: hydrogen is the body of endogenous gas, the human body is some members of the intestinal flora fermentation of dietary fiber energy, in order to balance the redox reaction The loss of electrons in the form of hydrogen released from the produce. If the food structure is reasonable, the flora structure is reasonable, then can produce more than 15 liters of hydrogen per day. Hydrogen dissolved in water, is a very good antioxidant, free access to cells, to reach the cells have superoxide free radicals will occur in the site of antioxidant reaction, remove these free radicals. This should be the basic mechanism by which hydrogen exerts its "magical" biological effects.
Professor Sun Xuejun, a diving medical expert and doctoral tutor of the Second Military Medical University, also proves that the hydrogen has never been a toxic substance in the human body, so that the use of hydrogen to treat the disease is safe An important prerequisite, may subvert the Chinese talk about "is the drug three drug" argument.
Helium oxygen diving can effectively solve the problem of air diving nitrogen anesthesia, so that diving in the depth of a breakthrough. However, with the diving depth increases, the gas density increases, respiratory resistance will still have an impact on the divers, especially helium almost no anesthesia, large depth of diving is easy to produce HPNS, and access to helium more difficult and expensive, these factors are Limiting the wide range of helium oxygen diving applications. Therefore, there is an urgent need to find new gases instead of helium as a large depth of diving with breathing gas. In fact, in the early stages of the study of mixed-gas diving, hydrogen was used almost simultaneously with helium for diving and high-pressure operations because of the barriers to helium preparation.
Hydrogenated hydrogens or hydrogens are used as diving for breathing gas, commonly referred to as hydrogen diving. Like helium oxygen diving, hydrogen diving is also a mixture of diving. Hydrogen diving is one of the hotspots in the development of modern deep diving technology. Hydrogen and oxygen diving, including hydrogen and oxygen mixture of conventional diving and hydrogen and oxygen mixed gas saturated diving, which, hydrogen and oxygen mixture saturated diving is the main direction of development.
Hydrogen loves the world "high concentration of hydrogen generator" through the latest SPE hydrogen separation technology research and development to obtain international recognition, by the media favorable. The generator is small, 3 minutes can be quickly prepared with 99.9% purity hydrogen hydrogen-rich water, hydrogen concentration of up to 800-1200ppb, easy to carry, has become more and more people's health first choice.
