People used to say that you’re supposed to “drink x amounts of water per y”. I’m fairly sure that that’s been disputed and you should really just drink when thirsty. Preferably water.

People keep telling me that. I'll feel like complete shit and have no idea why 'til I take a sip of water, find myself greedily guzzling the entire bottle, and realize I haven't had a drink in six hours.

"When you're thirsty" doesn't work for everyone.

it sounds like the classic "eat when youre hungry" advice. some peoples internal sensors arent calibrated correctly and theyll go all day without eating or always overeat

This is me. I really don't get hungry very often and as a result I tend to eat one meal a day.

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.

DoctorWaluigiTime t1_j6cv36s wrote

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."

> Your body will inform you when you're thirsty.

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.

You kind of are

My friend who worked out could only manage to get ab definition in the morning after he woke up

You sweat a lot in your sleep

I’ve always been told, if you’re thirsty that you’re already dehydrated.

BowzersMom t1_j6cjski wrote

That’s not true. Dehydration means you are taking in less water than you are losing to the point that your body isn’t working well. The first signs of mild dehydration include thirst, but also headaches, muscle cramps, dark urine, cool dry skin.

If you are just thirsty, you should drink some water. But just being a little thirsty doesn’t mean you are in danger of anything.

Aristox t1_j6cob6e wrote

The first signs of dehydration are not headaches and muscle cramps lol that's when you're already well into it. Your physical and mental performance will have already been reduced by the time you feel thirsty. If you're correctly hydrating you won't experience any symptoms whatsoever

….if you’re correctly hydrating you won’t be dehydrated. So of course you won’t experience symptoms of mild dehydration!

Well yes, that's what thirsty means lol.

That is not what being thirsty means. When you are thirsty you are down by a zillionth of a percent of what you'd need to be before you'd be close to dehydrated.

No, people think it's okay to be thirsty, and it's not. If you're thirsty, it's too late and you're already dehydrated.

UNFORTUNATE_POO_TANK t1_j6cc3hi wrote

What's too late? Your body has a very robust system to let you know if you need more water. You can go days without. Strongly not advised, but being thirsty doesn't mean too far gone in any way.

RockinMadRiot t1_j6d1hz8 wrote

Think of it this way, the brain is 80% water. So just as much as 2% dehydration can really effect its performance and cause issues.

Aristox t1_j6codeg wrote

Just because you don't die doesn't mean your physical and mental performance aren't reduced. You absolutely cannot go days without being dehydrated

Sorry, no. The way most people talk about this, it's horse shit, although that doesn't stop the myths from persisting:

Use it, and you can stop sweating about hydration.

DoctorWaluigiTime t1_j6ctbkp wrote

Indeed. If thirst meant dehydration, then everyone sleeping for 6+ hours a night would be dehydrated every morning lol.

RockinMadRiot t1_j6d1n90 wrote

But you could argue that we aren't doing as much in our sleep so using less fluid, when awake that's a different matter as we are using everything, including our brains.

Edit: just re-read, yes I agree with you. Thirst is just a sign you are starting to get low and need water, if you ignore that then very likely you will have dehydration

WeirdlyTallDwarf t1_j6chclu wrote

This is like saying "if you're hungry, you're already malnourished/starving".

Silly, is it not?

Aristox t1_j6coiyn wrote

No it's radically different. If you haven't eaten enough food your body will burn fat for energy. But your body has no alternative hydration source. You can go a month easy without food, you cannot go more than a few days without water and still live. And you cannot go a few hours of being lightly dehydrated without your body's performance falling below optimal

Tiramitsunami t1_j6d2gz2 wrote

You are almost NEVER dehydrated. It's a myth. You don't need to drink nearly as much water as the current fads make it seem. You certainly don't need a personal water bottle. If thirsty, drink, and that's all you ever need to do.

LoneStar2911 t1_j6bzgee wrote

Disputed perhaps, but not disproven. At least, not to my knowledge. I would say the majority of doctors, biologists, etc still agree on “you should drink x amount” (typically depending on your body weight). But yes, I’ve heard of it being disputed. And as the other commenter said, I was also told that once you’re thirsty, you’re already showing signs of dehydration. Until it’s widely accepted that there’s no need to drink unless thirsty, I’ll stick to what I’ve been taught this far. Besides, I don’t like being thirsty. lol

It is so variable that any advice besides "when you are thirsty" is pretty meaningless. There is wildly variable amounts of water in all the foods you eat and you lose water depending on activity, temperature, humidity, size, diet, and health. You can get some feedback from urine (clear is probably a little too much and dark yellow is not enough) but basically just listen to your body. It generally does a pretty good job.

Lordcavalo t1_j6c2nc8 wrote

Whats been disproven it's not that people should drink x amount of water, that would be absurd, the problem is when people say "you have to drink 8 cups of water per day" which is false, most of the water we consume is through alimentation, people need their amount of water but it's not a fixed number, some people might need 8 cups others might not need at all

UNFORTUNATE_POO_TANK t1_j6ccegg wrote

I don't know what alimentation is supposed to mean in this context, but generally yeah it just means giving your body nutrients. Drinking water is a form of alimentation, supplying your body with nutrients.

Lordcavalo t1_j6cnj2v wrote

Yeah I'm sorry I could've just have written simple but I'm dumb, I meant food (rice, steak, chicken, ...)

I think that it's pretty clear now that English is not my first language 😂😂

No worries. No trying to call you out. Just trying to make sure I wasn't missing anything myself.

Yeah, I pretty much said it’s not a fixed number for everyone. I said it’s typically determined by a person’s weight.

It's very debunked. It's just one of those rare not-backed-by-the-evidence health fads popular on the left, so it gets traded around in different circles than the usual stuff.

A poster at my gym says to drink 1ml of water for every calorie of food you eat. I don't know if it's based on any science, but it sounds pretty reasonable. Better than 3l a day no matter if you're 5 feet tall or 6 foot 5.

I too get thirsty at bed time but have to avoid drinking too much water. Nothing worse than walking up to pee lol.

I think it's incredible that the body can learn and adapt to your own routines like that. I do a daytime fast every year for three weeks, so i don't eat food or drink while the sun is up. Within just a couple days my body catches on and I end up needing to pee an hour before sunset everyday like clockwork. Like my body is like, "it's 5 O'Clock, the idiot is going to start drinking again, we can release the reserves." It's just wild.
