Can You Drink Too Much Water?

For the average man, you should drink about 3 liters a day and women should drink about 2.2 liters. What happens if we drink significantly more than this? If you drink too much, this could lead to water intoxication and a dilution of sodium in your body. This is most commonly seen in infants and in athletes. 

So what happens during water intoxication? Our tissues swell and we try to use the sodium in our bodies in attempt to reestablish the necessary concentration. Swelling of the brain tissues can lead to seizures, comas and ultimately death. 

A healthy adult kidney can process about fifteen liters of water a day, so as long as you don't consume an extremely large amount at one time, your body most likely will be able to process this. In a lot of the foods we eat, there is a large quantity of water which is included in the daily amount of water we should have. Author Matt Stone, includes a list of symptoms you may experience if you're drinking too much water. 

Thankfully, drinking too much water is not that commonly. So unless you're planning on running a marathon and chugging excessive amounts of water, you should be in the clear. If you're afraid you're drinking too much water, add half a teaspoon of sea salt to your water to ensure proper hydration.


This post caught my eye IMMEDIATELY. I am a big fan of drinking water. I always have a refillable water bottle handy throughout the day. I use to do anything to not drink water. Now a days, it is all I enjoy drinking throughout the day. I read an article & found similar results to the one above. Especially how it is important to not consume large amounts all at once.

This is so strange to me, as I just commented on another blog post that touched on this issue. I had no idea that over-hydrating was an actual possibility until today, and now I am getting so much well explained information regarding the topic. It's good to know that this issue is not too common (sensibly, I might add given that fifteen liters is an intense amount of water to drink).

This is the blog post I was referring to:

I'm glad you pointed out that we do get a lot of water from the foods we eat. It is not always necessary to drink all your water. While the 3 liters of water a day for men is the recommended amount, that does not mean that you need to measure out 3 liters of water a day to drink. Any food you eat that contains moisture (from milk with cereal to mac and cheese) will help hydrate you. Of course, in some cases water content is balanced out by sodium. Either way, I usually beware of people telling me how much water I need to drink. This ( is a pretty cool list of foods that hydrate you to remind you how often we intake water through what we eat.

Lastly, I should add that water intoxication sounds rather uncomfortable!
