Drink 8 Glasses of water a Day?

Many people today believe you need to drink 8 glasses of water a day or you will suffer chronic dehydration and many other health problems. However, according to scientific american, unless you are at risk for kidney stones or urinary tract infections, drinking large amounts of water is not necessary. That is not to say that drinking water is not healthy, it is just that drinking very large amounts is not really necessary. The misconception of drinking 8 glasses of water a day came from a study in 1947 that stated that people usually consume 8 glasses of water in the food that they eat. Once bottled water came on the scene it misused this to sell water.Personally that seems like a scam to me. When you have water coming from your faucet, but you buy cases of bottled water. If you are exercising or something then you probably need more water than usual. However, drinking 8 extra cups a day is not necessary according to Dr.Valtin a professor from Dartmouth who specializes in kidney research. So only drink what water you need, the 8 cups a day thing is not true.


  1. I really, really liked this post. See I have been told for so long that you need to drink eight glasses of water a day. My boyfriend has actually told me quite a few times, that it's necessary but I never actually looked at the story or reason behind it. So I'm glad to know it's not actually true. I still probably will though because water seems to be my main drink. I enjoyed this post though. You covered all major areas. Thank you.

  2. This is interesting because I have heard this hundreds of time and assumed that it was a real statistic. I never connected it with the introduction of bottled water and the profit the gain from endorsing it.

  3. I like this post. I've also heard this many times, but never thought to connect it will the selling of bottled water. A few of my guy friends that are working out all the time always say that I need to drink at least 8 cups of water a day and I will be healthier, but now I can tell them that's not true! =)
