Drink water until the color of your urine is clear. Once it is, there is no benefit to drinking more.

Yea 2.5-3l seems to be the proper amount. Only drawback is having to pee every 30 minutes.
If you're peeing that much then evidently your body is not using all that water you're consuming. Either it's more than you need, or you're lacking in electrolytes and should increase electrolyte intake alongside the water.
Parent is correct. NHS sources say upto 7 times during the day is normal and "Every 3 to 4 hours is considered healthy. Going every 1 to 2 hours usually means you either have an overactive bladder or are drinking too much at once."
Saying every 30 minutes is normal is just the same as advocating drinking too much water

Are we sure this is not just harmless and arbitrary information being parroted? Do we have verifiable sources other that anecdote? I find it hard to believe that there is just a single value for water intake across the massive biological spectrum that is humanity and expect to see a range when this conversation comes up. You're also getting water from foods, which I am sure is not being accounted for. Reminds me of t…
I’ve always been extremely suspicious of constant water consumption. No other mammal seems to do this. Even the ones that require a lot of water like horses will only drink when they’re thirsty or while eating.
Most other animals have typical lifespans that don't top two decades.

The point is you shouldn’t wait to drink until you feel thirty. That’s too late. Your muscle has been consumed by then.
Its aggravated because the "water sensor" appears to fail early with age. Elderly people tend to not get the thisty feeling as often, but get dehydrated anyway.

Indeed. That’s why I form the habit to drink 3 liters everyday to keep my urine white transparent.

It’s a glass of water an hour. Hardly excessive.
It doesn't do anything to drink so much water. It is a purely American myth/trend. https://abcnews.com/Health/Wellness/waterlogged-america-drin...
I feel much better when I drink more water: head, eyes, and body. And if I don't drink enough water during the day I'll cramp at night. Drinking lots of water to lose weight is nonsense – on this I agree.

#67The more I age the more important hydration turns out to be. Gastric issues, joint pain, blood pressure, weight problems, kidney stones, bad breath, constipation.. and now brain issues too? Do yourself a favor, and start drinking a ton of water!
Not too sure - an overload of water can actually be dangerous i think.
Since no one is being quantitative, here's a medical source:
https://my.clevelandclinic.org/health/diseases/water-intoxic...
> In some people, water intoxication symptoms can develop after drinking about a gallon (3 to 4 liters) of water over an hour or two.
> More than 32 ounces (about a liter) of water per hour is probably too much.

it's a matter of habit. 3l of liquids per day is what various doctors in different (european) countries have recommended me over the years.

sure, there are different recommended amounts, the EFSA recommendations are 2.5l per day for a grown up man and 2l for a woman[0]. I'm a bit bigger than the average so I got 3l as a recommendation when I was on a diet or when I had specific issues.
But I didn't mean to imply everyone should drink it, just that it's not hard to drink that much. And yes, of course you ingest a lot of water through other means too.

I wonder how much of the effects of ageing are due to cascading failures downstream of alterations like these. For example, it's common for people to lose teeth in advanced ages. How much of this is due to dry mouths from insufficient water intake? Fallen teeth then may become entry points for infections, et cetera. Perhaps fixing a few early causes we can avoid a lot of negative effects and live more, without the need to go full spartan in lifestyle discipline.

#70Honestly I don't get why we don't educate more on how to manage water consumption and hydration. It's highly situation dependent and both about listening to your body (natural thirst) and pre emptively anticipating water needs.
If you are going on a multi day backpacking trip in the desert you are going to be consuming a lot more water than sitting at your computer in an air conditioned office reading HN. And you also are going to need to be very cognisant of consuming adequate amounts of electrolytes (particularly magnesium and salt). You also would be wise to "camel up" at least a bit beforehand to make sure you are at peak hydration at the beginning (and of course anticipate carrying enough water with you or knowing potential water sources you can filter from).
People who are into running also become aware of this and those who do any activity in extremely cold and dry environments.
In addition most people have a base level of water loss (even while sleeping) through your skin that varies but is I believe around a half liter (specifically 400ml or 14 fl oz) per 24 hours. This is not the typical sweat out of your armpits from being a bit too hot - it's known as "insensible perspiration".
Water management is a very valuable skill and much more valuable than just trying to have some blanket "liters per day" recommendation. And getting water from your food is never a bad idea either !
