Reply to comment by PhasmaFelis in ELI5: why do our bodies randomly act like we haven’t had water in days and that we need to chug a bunch randomly? by Serratedlily
It's okay to not drink water that long. Your body will inform you when you're thirsty. I suggest next few times you are thirsty you don't chug the whole bottle all in one go, however.
And yes, "you must have X amount of water a day" is bunk. Your body will not let you get into states of dehydration (which occurs long after "I haven't had a drink in six hours" -- you do that every night when you sleep, and you aren't in a state of dehydration when you wake up).

that said you probably won't exert yourself as much when sleeping as you do when actively moving around and sweating.

Of course, but my point is that thirst or dehydration doesn't happen by virtue of "it's been 6 hours" or whatever. It takes a day+ at minimum to start getting to danger levels unless you are actively working out / doing more than hermit-ing in the household.
Which again, your body will inform you of this, long before you get to actual dehydration (headaches et al). "I'm thirsty" is not the same thing as "I'm in a state of dehydration."

My body doesn't. That's what I'm telling you. I feel like shit, I don't feel thirsty; as soon as I drink something I suddenly realize I'm thirsty, drink a bunch, and immediately feel better.
We're not talking about life-threatening dehydration. We're talking about thirsty enough to feel bad, but my body isn't sending "drink something" signals.
