Resolved How much water one needs to drink a day

some ppl say that you should have a glass between meals + the one you drink with meals.

 

Because coffee is a diuretic and laxative. It helps you remove toxins and encourages you to shit and piss. So coffee (within reason) is great for keeping you healthy but terrible for keeping yourself hydrated.

 

There is no way to calculate how much water you need to drink. All those guides are bad science by bottled water and energy drink companies to sell more product just drink when you are thirsty don't force yourself to drink. Exercising will actually make you retain more water not expel it. You are more likely to kill yourself by drinking to much water than not enough other than if you have certain medical conditions. You body is evolved to tell you when you need to drink

 

at least 2 liter of water, meaning a minimum of 10 glasses (1 glass is 2 dl /8 ounces)
But a there is no need to drink that many glasses if you include the moisture in air,food etc

 

As a science student, it kinda hurts, but this is right.
Research is friggin' expensive, and instead of relying on funding or whatever to get money, some (dont wanna say many) scientists turn to being paid by different companies to check this or that in a way that benefits them, basically faking their results through specifically picking out the experiments that give the desired result, totally disregarding their actual accuracy or relevance, just to get money for their actual research, which usually doesnt even come out half as big as their 'paid research'.
And thats still disregarding those that are simply greedy.
But, that doesnt mean that all research and studies are fake.
Thats seriously ruining science, though.
Its not science as a whole thats unreliable, just some individuals doing it.


And at the same time, while it might sound like we actually know everything, we dont. And at the speed everything advances nowadays, it might take less than 10 years to oberturn something that was believed to be true.


Sorry for going off topic, but i kinda wanted to say this~

 

If you are actually feeling thirsty then that means you are dehydrated. You’re not supposed to be thirsty. Your brain can’t actually differentiate between hunger and thirst, but if you’re actually feeling thirsty or your mouth/throat is feeling dry then you are dehydrated. If you’re still feeling hungry after having a meal then that means your water intake isn’t enough. Or you could actually be still hungry.

It is 2L of water, but many of your food sources contain water which can bring that number down. I personally only drink about 1.5L a day but if I’m physically active then I do end up consuming more water.

Anyway, water is healthy for you because it can regulate your body weight, provide lubrications for your joint, and help process water soluble nutrients, and many other importantly functions.

 

On road crews on hot days 30c+ we were expected to drink 4-5L in a 9 hour work day

 

for additional advice, don't freaking drink 2L of water in one sitting......just drink when you are thristy or you are sweating...you have 24 hours a day, drink when you need it....

 

In my opinion, if your doctor didn't told you the quantity needed but only 8 glasses of water that's should mean it can be any kinds of glass of water, small or big and this is in the margin of errors, acceptable range.

 

2L, if you’re very active or sweat a lot then you may need to drink more.

 

I have 15-20cl glasses, my parents have 33cl glasses. There’s a HUGE difference

 

I have low blood pressure. So, the doctor recommended to only drink water because water helps with the blood flow. I was told that only water can be digested or processed properly, yet any juice or soda.... more than 70% is wasted, undigested.
Thus, in order to keep my blood flow in normal level.... I drink a lot of glasses of water. I would drink at least 20 per day. If it is juice or a cola... I would need way more to satisfy my needs + not really healthy.

Anyways, it was interesting that even natural juice or drinks with a lot of vitamins/nutrition only 30% of it gets digested. Only water is fully digested/absorbed by the body.

 

from where did you hear this bs?
the reason why the body don't absorb that much have nothing to do with water or soda, but the fact intestines can absorb only a limited ammount of liquids at times, the other you litteraly piss it off.....you need to drink a little at times during the day, drinking a lot of glasses of water doesn't help you at all.......

 

5 litres if I'm not wrong

 

Wouldn't the amount of water you need to drink depend on things like your size and how much you spend in the sun or exercise? People shouldn't confuse generic guidelines with what is best for an individual.

If anything, your diet (not to be confused with not eating anything, but more of eating slowly, chewing properly and sticking to food that you are not intolerant to, you can still eat delicious food even when dieting) and plenty of exercise like this:







The cats are mandatory

 

much enough that you don't feel like puking in one sitting drink. work for every liquid cosumed by human.

 

Actual doctor.
Maybe didn't express myself properly but water is needed & helps the blood flow, which can help those with low blood pressure. I don't know about others but I have a issue where I go low energy to the point people think I am on drugs/zoned out, eyes dead & even head/body feels drained. I do think since I started to drink way more water, it has helped... I rarely get as bad, drained or low energy as before.

Blood flow is related to blood pressure, heartbeat & so on.

 

No. Just because you feel thirst does not mean you are dehydrated, it depends on how you define thirst.
Thirst because of dehydration just as you said, with a dry mouth, throat and a desire for water.
But you can define it simply as the desire or need to drink as well. (Merriam-Webster)

A simple experiment one can do is having a bottle of water near oneself throughout the day, on the desk for example. You will in all likelihood feel an increased desire to drink said water after some time, even if your throat isn’t really dry or anything.
Now try going without an easily accessible water source for a day. Chances are, you won’t feel the need drink until lunch where most people automatically consume water or the like with their meal. Though maybe you’ll even be fine until much later without drinking at all, it really just depends on how active you are throughout the day...

Also, your brain can definitely differentiate between hunger and thirst, they are two distinct needs.

 

that cat harassment!

sigh~
sometime I wonder what teacher teach on school these day

aye I know that feeling even just lil project back on highschool make me resign from competition cuz I have no money to fully do it
sure I was idealistic still from that I know on commercial side there some compromise regarding science

balancing out between commercial and pure science is hard
