At my local hardware store they sell something called “Demineralised Water High Purity” and on the back of the packaging it says something like, “If consumed, rinse out mouth immediately with clean water.”
Why is it dangerous if it’s cleaner water?
In: Chemistry
An explanation from medicos I’ve asked is; lots of things on your body work by transfer of chemicals and ions. By drinking water that is devoid of those (something biological systems never evolved to interact with) you can kinda “wash out” those chemicals your body is used to, and fuck up your kidneys. That’s a very broad and pretty innacurate explanation, but it gets the intuition across. We have biological systems to filter out stuff that isn’t good for us, but we don’t have systems to help us drink something that doesn’t really exist in nature.
