What does hydrogen water do? What is the role of hydrogen water?

Hydrogen water is rich in hydrogen.

Japanese studies have found that hydrogen-containing water can scavenge free radicals and have health effects, but from a scientific point of view, it is of little significance. First of all, water has very little ability to dissolve hydrogen, and it may absorb less hydrogen through the gastrointestinal tract, and even if hydrogen is inhaled, it is difficult for it to enter the bloodstream without a hydrogen carrier. Secondly, hydrogen is stable in normal environments, only in high-temperature environments.

In order to react with other substances, which is not possible in the body, even if some enzymes can activate hydrogen, it is the hydrogen free radical that is generated, and this hydrogen free radical is with the oxygen free radical.

It is uncontrollable whether it is neutralized or reacts with other substances. So this theory is unreliable, that is, hydrogen water has no effect.

Zhihu's consistent style is to say whether it is or not first, and then say how.

First of all, hydrogen production water generally refers to water that has dissolved hydrogen. It is said that hydrogen has antioxidant effects due to its reducing properties. I would like to say that although hydrogen does have a certain degree of reducibility, it is debatable whether it plays a role in the human body.

It is very common to dissolve gases in water, for example, carbonated drinks that we often drink dissolve carbon dioxide. If drinking hydrogen water can replenish hydrogen in body fluids, then is the soda we drink filling the body with carbon dioxide? An analogy can be obtained:

Drinking water containing hydrogen does not replenish hydrogen, and if you do drink it, it is likely to be excreted through hiccups.

Secondly, if it does enter the human body, how will it enter the body? The main digestive organs of the human body are the stomach, small intestine and large intestine, and the main function of the stomach is to store food temporarily, not the main absorption organ. The small intestine absorbs nutrients through the villous parietal cells of the small intestine.

There are no organs and tissues in the human body that specialize in absorbing gas, so it is a problem for gas to enter the body.

Finally, even if oxygen does enter the body and is transported into the blood vessels, will it really work? Does oxygen really react with hydrogen? It's in bodily fluids!! How does this react?!

Hydrogen water, also known as hydrogen-rich water, is obtained by dissolving hydrogen into water by a certain means, and is called "hydrogen water" in Japan (hydrogen is called "hydrogen" and oxygen is called "acid" in Japan).

There are generally three ways to produce hydrogen water:

1. Magnesium rod method.

Magnesium is inserted into water, and due to the high activity of magnesium, it displaces with water to produce hydrogen:

mg+2h₂o=mg(oh)₂+h₂↑

2. Pressurized dissolution method.

Carbonated beverages such as soda and cola dissolve carbon dioxide into water under pressure, hydrogen can also be pressurized to increase its solubility in water.

3. Electrolysis method.

Water electrolysis produces hydrogen and oxygen, the negative electrode produces hydrogen, the positive electrode produces oxygen, and the oxygen at the positive electrode is released.

Attention, attention, attention (important things are said three times):

Some businesses trumpet their health care benefits, but the benefits are not significant or even suspicious.

1. All the existing health care benefits of hydrogen water are claimed by merchants or are irregular test resultsThere is no authoritative inspection agency verification, no clinical trial conclusion, no national supervision and inspection agency certification

2. The role of oxygen radicals in the human body is not all negative, superoxide ion group and hydrogen peroxide (HO) are important signal transduction molecules, and they can regulate physiological processes such as apoptosis, proliferation and differentiation, and hydrogen peroxide can also be converted into hypochlorous acid with bactericidal effect; Another example is nitric oxide radicals, which are important neurotransmitters and important participants in the diastolic process. Even if the merchant's claim of hydrogen radical neutralization of oxygen radical function is true, then,The reduction of oxygen free radicals is not necessarily a boon for the body

When the intestinal flora breaks down and digests food, it produces hydrogen(The reason why farts can ignite is that they contain combustible gases such as methane and hydrogen), and this amount is not small, with the average person producing 12 liters of hydrogen per day in their intestines. Isn't it scary? In fact, only a few of these hydrogen gases are eliminated in the form of farts, and most of them are absorbed or participate in reactions such as the decomposition and synthesis of other substances.

If calculated according to the saturation concentration of 18ml l of hydrogen water (at room temperature and pressure).You also need to drink 666 litres of hydrogen water a day to match the hydrogen produced in your own intestines

National Mandatory Standard "National Standard for Food Safety Packaged Drinking Water".(GB 19298-2014) was approved and issued by the National Health and Family Planning Commission on December 24, 2014, and implemented from May 24, 2015, and the labeling requirements for packaged drinking water in the standard were implemented from January 1, 2016. It clearly states: ".The name of packaged drinking water shall be true and scientific, and shall not be named after one or more components other than water.

The product name of packaged drinking water shall not be marked with "activated water", "small molecule water", "functional water", "energy water" and other unscientific content.

Therefore, the so-called "hydrogen water", "hydrogen-rich water" and "hydrogen water" you buy are all illegally produced and sold.
