# Should we actually drink 2,5 liters of water a day?

Remember the rule of 8 glasses of water a day? Be sure that it's a myth. And we'll explain you why.

#### Aqua Mechanical CC BY The media insist that people should drink about 2,5 liters a day, even when they don’t want to. Professor of Pediatrics and an author, Aaron E. Carroll, believes that there is no scientific evidence to follow this advice. pexels Public Domain Mark Nevertheless, the advice works, playing on our fear: if the body does not get enough water, there can be serious health problems. pexels Public Domain Mark Recommendations about 2.5 liters of water are right, it’s just as much as we need, but…You should always remember that most of the water is contained in food, vegetables, fruits, tea and coffee. publicdomainpictures Public Domain Mark If you rarely want to drink and think that there is something wrong with you, do not worry: the body will signal you long before dehydration.Besides,excess of water is as harmful as its lack, especially for your kidneys. pexels Public Domain Mark If you feel that you want to drink then drink. However, forget about these 8 glasses of water a day. Learn more about life with QuizzClub:

8 eight ounces glasses of water is 64 ounces, which is 1.89 Liters. So if you can&#39;t get the math right why should I believe any of your other assumptions.

I never drank water until I started having heart attacks from dehydration. Now I drink 4-16 oz water bottles EVERYDAY. I gave up coffee and tea also. I start at 9:30am and finish at 9:30pm and sleep all night through. Miss coffee. Don&#39;t miss the heart attacks. Thery&#39;re rough and don&#39;t get any easier even after 5 attacks.

You assume the glasses hold a volume of 1 cup. Perhaps the 8 made u draw that conclusion? Either way, most glasses are larger than 8 oz, and nowhere does it say 8 8 oz glasses.

I think the recommendation is actually about half your bodyweight in ounces, depending on your local climate.

Richard Rettke I too have heard the 8x8 rule many times. However, since no value for oz is given, you can easily find out by solving for z, where z= fl oz per glass. 2.5L=84.54 fl. oz, so 8z=84.54, divide each side by 8 and you&#39;re left with z=10.57 fl. oz.per glass. Elementary. 2 1/2 oz is like two large sips. Never assume, as you suggested in your original post. That was the only thing I was getting at, not insulting you or saying you&#39;re wrong. Nowhere do I read you go by the name Ricky, but I have heard that many times as a name for Richard! Still, I wouldn&#39;t assume you go by Ricky just because it doesn&#39;t say otherwise.

Chris Braun Do this google search how many glasses of water should we drink a day? The 1st hit you&#39;ll get is this one. EIGHT There are many different opinions on how much water we should be drinking every day. The health authorities commonly recommend eight 8-ounce glasses, which equals about 2 liters, or half a gallon. This is called the 8&#215;8 rule and is very easy to remember. Subsequent hits also recommend 8 - 8 ounce glasses of water. So my conclusion was drawn on 67 years of getting the same information. As you can see your comment &quot;nowhere does it say 8 - 8 ounce glasses. is blatantly incorrect. If you meant, no where in the question does it say that, it also doesn&#39;t say otherwise!

the body dispels 2.5 litres a day according to some naturopaths so u need to replace it with water but intra-cellular water level is a key to good health but people who drink clean filtered water have clearer skin. dehydration is very common...

I drink at least 2.5l but not because I&#39;m thirsty it&#39;s just easier to drink than eat on the move. (ans makes for more toilet breaks lol)

There is so much conflicting info and some purists say it should ONLY be water (or herbal tea at a stretch). Personally I think we probably should stay reasonably hydrated, but bear in mind that too much can be as bad as too little.

I think they&#39;re talking about 10 cups @ 250 ml per cup...the usual size of a cup. Some heart patients should limit their fluid consumption to 6 cups from what I&#39;ve been told. Also salt should be of minimal use. Their effect on the kidney, heart, liver is beyond me

Kathy Phillips, correct. The kidneys can only handle 500ml/hr. There is a thing called water toxicity...it can kill you...

The rule of thumb, especially in the tropics, is one litre per 30kg of body weight and then you have to add for every hour that you are sweating or in air conditioning. Fifty percent of all aches, pains and headaches are due to dehydration.

I was advised to drink less wine and drink more water. I did that,ended up drinking too much water,and washed the salt out ,which caused more problems. I’ve given up alcohol and drink what I feel.like and never felt better.
