The "8 glasses of water a day" thing is literally just made up by employees of Coca Cola. To sell more aquafina. Never quite understood how people believe that peeing every 20 minutes makes one healthier. There's no evidence for it.

This is an ADHD meme community sir/madam. We are not functional enough to drink a couple of glasses a day, let alone 8.

AKA 1945 US Food and Nutrition Board? Because that's where it seems to come from.

Apparently I was victim to a widely circulated myth. Apparently though, that board also specified that most of that recommendation was covered by water within food. The "IT HAS TO BE ACTUAL PURE WATER" thing was added on later by others.

So where did the myth of the 8 glasses come from? Fox says it likely stems from a decree from the U.S. Food and Nutrition Board issued back in the 1940s. It suggested that everyone drink 2.5 liters (84.5 ounces) per day — so not far off from today's standard. But even back then, that same recommendation clarified that a majority of that water comes, not from a glass, but from "prepared foods."

I feel like my grandma said this in the 1980s before Aquafina was a thing.
