What is Molecular Hydrogen?
Molecular hydrogen gas, or H2 (g), is the primary form in which hydrogen is found. In other words, two hydrogen atoms (H) are covalently bonded (a type of chemical bond) together as H-H. Because there are two hydrogen atoms, we call this diatomic hydrogen, di meaning two. Because the hydrogen atoms are covalently bonded together they form a molecule; so H2 is also referred to as molecular hydrogen. We can also refer to it as dihydrogen. The hydrogen molecule contains two protons and two electrons making it a neutrally-charged molecule. It is a colorless, odorless, tasteless, non-metallic highly flammable gas, and very explosive above a 4.6% concentration by volume. Hydrogen is the smallest molecule in the universe, and this extremely small size and its high lipid solubility allows it to easily diffuse into the skin.
What is hydrogen water?
Hydrogen water or hydrogen-rich water (also called hydrogen-enriched water) simply means normal water (H2O) that contains dissolved hydrogen gas (H2). For example, there are carbonated waters or beverages (soda pop), which contain dissolved carbon dioxide gas (CO2), or oxygen water, which contains dissolved oxygen gas (O2). Similarly, you can have water that contains dissolved hydrogen gas.
Think of it this way: you can make hydrogen water by taking a tank of hydrogen gas (just like tanks of helium used to fill balloons or tanks of oxygen gas used in hospitals), and bubbling it into a glass of water. There are also many other methods to make hydrogen water. It is simply water that contains dissolved hydrogen gas.
Doesn’t water already have hydrogen in it because water is H2O?
The water molecule has two hydrogen atoms, chemically bound to the oxygen atom. This is different from the hydrogen gas molecule (H2), which is just two hydrogen atoms bound only to each other.
Here’s an example: we need oxygen (O2) to live, so why can’t we just get our oxygen from drinking water, H2O? It’s because the oxygen is chemically tied up in the water molecule. We need available oxygen gas, (O2) that is not bound to other atoms or molecules.
Furthermore, virtually everything has hydrogen atoms in it, but those hydrogen atoms are chemically tied up with other things. For example, a water molecule has two hydrogen atoms that are chemically tied up with the oxygen. Or, a sugar molecule like glucose contains 12 hydrogens, but those hydrogens are all bound to other carbon and oxygen atoms.
Is hydrogen safe?
Yes. Hydrogen gas has been shown to be very safe at concentrations hundreds of times higher than what is being any home type generator can produce. Here are a few examples:
Hydrogen’s safety was first shown in the late 1800s, where hydrogen gas was used to locate gunshot wounds in the intestines. The reports showed that there were never any toxic effects or irritation to even the most sensitive tissues.
Another good example of its safety is that hydrogen gas has been used in deep sea diving since 1943 (at very high concentrations) to prevent decompression sickness. Studies have shown no toxic effects from hydrogen when at very high levels and pressures of 98.87% H2 and 1.26% O2 at 19.1 atm. Furthermore, hydrogen gas is natural to the body because after a fiber-rich meal, our gut bacteria can produce liters of hydrogen on a daily basis (which is yet another benefit from eating fruits and vegetables).
In short, hydrogen gas is very natural to our bodies.
