Imagine you pour a carbonated drink like soda into a glass and let it sit for some time. At some point all carbon dioxide (those bubbles of gas) will dissipate back into the air and you will no longer feel those bubbles popping on your tongue when drinking it.
If you, on the other hand, keep the original packaging unopened where the carbon dioxide is kept under the right amount of pressure, its presence in water will last for much longer. The same principle applies to molecular hydrogen (H2) gas but there’s a big difference in the reason why we want to dissolve H2 in water in the first place.
H2 has been found to have major therapeutic benefits to the body (see our blog post titled The Benefits of Molecular Hydrogen) in over 600 studies and the interest of the scientific and medical community is growing daily.
H2 is a gas
When dissolved in water under pressure, H2 form so called nano-bubbles (very small). The beauty of it being present in water in its gaseous form is that it can get readily absorbed through the tissues in the body. It’s so small that it can easily penetrate the blood brain barrier in the brain as well as through the intestinal wall into the bloodstream and into your cells’s energy factory where it can perform its one of its therapeutic functions – neutralising the most cell damaging free radicals.
We can measure dissolved H2 through either using an H2 meter or H2 blue reagent (more on this topic in another upcoming blog post).
Designed to be drunk fresh from the tap
Hydrogen-rich water technology is generally designed to provide households, offices, gyms or yoga studios (etc.) with filtered clean fresh hydrogen-rich water on tap. The actual hydrogen-rich water produced this way isn’t to be sold with the intention of having a long shelf-life. There are H2 water pouches available on the market which are made from aluminium. Only these are able to hold hydrogen for a longer period of time. Although it’s a great solution when no other option is at hand, it certainly wouldn’t be the solution of my choice, simply because it’s replacing a plastic bottle by another disposable packaging.
In order to get the most of the therapeutic benefits of H2, drinking fresh hydrogen-rich water on tap, produced by a high quality hydrogen-rich water unit is the most convenient and efficient alternative. Even if you’re not working from home, hydrogen levels will still be sufficient after a few hours of carrying your water bottle around although it’s important to say that hydrogen levels will eventually go down and escape completely.
How long the dissolved H2 lasts in your water depends on three factors:
1/ Exposure to air
2/ Container material
1/ Exposure to air
When poured into a pint glass ( roughly 20 US ounces) of water, the hydrogen can easily last for a few hours and H2 will eventually dissipate. Our assumption is, however, that it doesn’t take you a few hours to drink that much water so you’re fine with that one.
A closed container is much better for keeping the hydrogen in longer.
2/ Container material
The best materials to use for hydrogen-rich water storage are high-quality stainless steel and glass. Plastic wouldn’t be my personal favourite, but if you there’s no other option, choose a higher quality BPA free bottle.
If you fill up your water bottle all the way to the very top with no air space in it and you put a nice lid on it that seals very well, you can keep the hydrogen for up to 10 days.
You need to keep in mind, however, that because it’s a gas, it’s going to decrease each day – roughly by .1 parts per million (ppm) when kept in a cool environment with no direct sunlight. So if you start at 1ppm on day one, on day eight you may only have .2 parts per million dissolved H2. By 10th day you may have lost all of your hydrogen… or you may not.
We said you may not lose all the hydrogen by day 10 because it depends on the temperature of the water. The colder the water, the slower the hydrogen gas moves. For that reason, it might be best to keep your bottle in a fridge.
And the practicality of it all? If you have a hydrogen-rich water machine at home already or you’re planning to get one, don’t get too hung up on it all. Worrying, stress and anxiety can do much more damage to your body than happily enjoying a clean glass of water even with very little or no hydrogen in it!
