Light Water!

I haven’t tried this yet, but light water promises to be amazing. And you can make it yourself.


The water you are now drinking contains deuterium (except in very rare cases). Deuterium is a hydrogen atom with an added neutron – making it heavier than normal hydrogen. But it still combines with oxygen to make water: heavy water.


The thing is, water is involved in just about everything your body does to maintain life. The less deuterium there is in the water, the better water works in your body. So light water (with reduced amounts of deuterium) should be pretty amazing.

I couldn’t find much online about it, but With New Method, China can mass-Produce Light Water for its Citizens’ Thirst, gives a good quick overview. It says:

Water with higher concentrations of D2O is known as heavy water, and it is harmful to plants and animals. By contrast, water with hardly any D2O — or light water — can boost the immune system and benefit plant and animal health, according to several studies. In one study from 2003, plant photosynthesis increased with the use of light water.

There are only a few drops of heavy water per quart  (150 ppm) in America, but reducing this by a third can have a significant impact on health. Here is how you do it:

  • Fill a jar part way with water, and put in in the freezer for about 15 minutes until ice forms on the top.
  • Break through the ice and pour the water off into another jar.
  • Put the jar of water out in the sun for a half hour.
  • Repeat the freezing process a second time and pour the water off into a jar.
  • Put the jar of water out in the sun for another half our.
  • Repeat the freezing process a third time and pour the water into a jar.
  • This water is ready to use. It should have about 100 ppm of deuterium (a reduction of about a third)
  • You can test your light water by putting an ice cube from normal water into it. The ice cube should sink in it instead of float. Take the ice cube back out after your test.

Be careful not to break your jars during the freezing process. A full jar is likely to break. A flimsy jar might break. Canning jars are good for this, since they are pretty tough.

You can drink as much light water as you want.
