Heavy water is indeed used in nuclear power plants (mostly some older designs, I think), and in various physics, chemistry and biology experiments. However, if you haven’t heard about this type of water here are a few bits of information to get you started. People have died from it. If you drink too much water, you can suffer a condition called water intoxication or hyponatremia. Mammals, such as rats, given heavy water to drink die after a week, at a time when their body water approaches about 50% deuteration. There are physical differences between light and heavy water. You'd be in no danger at all from radiation. India is the world’s second largest producer of heavy water. In limited quantities, yes. I can imagine what it’s like to depend on thickened water.

Consuming D 2 O won’t harm you because deuterium isn’t radioactive, so you don’t need to worry about radiation poisoning. In some rare cases, excessive water consumption can even be harmful. The deuterium in it is stable; it does not decay. Heavy water ice will actually sink in light liquid water. Heavy water is like regular water with hydrogen replaced by deuterium. “In athletes or people who are exercising for hours, if they’re only drinking water, they can … I mean, you /can/ but whether or not you should is a completely different question there.

If you’re organizing the chemicals in your closet, don’t get the deuterium and the tritium mixed up. Can you drink heavy water? You can, however, actually take your quest for hydration too far..

One key issue is that heavy water disrupts mitosis, the type of cell division used to repair injuries and grow new cells. It is chemically the same as normal water (H 2 0) but the hydrogen atoms are of the heavy isotope deuterium in which the nucleus contains a neu­tron in addition to proton found in the nucleus of any hydrogen atom.
