How Much Water Should You Drink?

tumblr_m28bi2R0JD1qj4hmpo1_500As I’ve mentioned before, drinking enough water is absolutely essential. Aside from keeping your body functioning properly, water can boost your metabolism, clear up your skin and even help curb hunger. And that’s just for starters.

So just how much water should you drink each day? It depends. The answer is dependent on a number of factors including gender, activity level, environment, health conditions and whether or not you’re pregnant or nursing.

While most of us have heard that we need to drink eight glasses of water a day, the reality is a bit different. According to the Mayo Clinic, men should aim for about 13 cups of water per day (3 liters) and women should drink 9 cups (2.2 liters). It’s a bit more than what we’ve been taught in the past.

If you exercise, you’ll need to consume more liquid – and possibly a sports drink (or something with sodium) to replenish electrolytes. The amount that you’ll need depends on the intensity and duration of the exercise performed.

Moreover, the environment plays a big factor. If it’s hot or humid, it’s important to replace liquids lost from sweating. Higher altitudes will also cause increased urination; additional liquid consumption is advised.

And, of course, many illnesses and health conditions require additional liquids. As does pregnancy or nursing.

But if you’re looking for a simple tip to help get your daily water intake, pick yourself up two, 1-liter water bottles (or three, 1-liter bottles if you’re a guy). On the bottles, mark a water goal for each hour or two. As your day progresses, make sure you’ve kept up to the goal. You can keep the bottles in a refrigerator or even just nearby on your desk. By the end of the day, you’ll have consumed the full amount.

It’s a really easy tip to help build a healthy water habit!

  1. Is there even enough fresh water on earth for everyone to get the amount of water they need on a daily basis?

    • There is enough fresh water on earth IF things change. For one, shipping water out of the natural water table and into deserts forever dwindles the amount of available, clean fresh water.

      Urban runoff into the ocean doesn’t help any. Also, Africa tends to be quite water rich if something can be done to prevent corrupt companies and governments from polluting local water supplies.

    OMG!!!! I was looking an answer to this!!! I’m always worried because i think i don’t drink enough water, and it was because i have a misunderstood idea. It’s really important to drink water and now i know how to do it. Thank a lot for the Tip!!!

  3. Great idea, I am gonna mark up bottles like this for my cocktails! In addition to water it’s also good to get the right amount of booze throughout the day!!! 🙂

  4. I’m always afraid I’ll drink too much. I’m big on fluids.

  5. I don’t think you can actually drink too much because your body wont let you. Unless you trick your body and drink some kind of drink or juice.

  6. Thanks for sharing this. I have been trying to increase my water intake lately. I am at about 7 cups a day, and would like to get up to about 12. Sometimes its hard, especially when you have a small bladder.

  7. Hi Dave

    As an older fitness guy I find when I drink 8 oz. of water every hour on the hour through out my work day I have incredible energy… and the added benefit of a more upbeat/positive outlook (probably due to the added energy!!).

    Great article!

  8. Hey Davey, heres an interesting BBC article that runs counter to your advice…

  9. Water. How do other fluids fit into the calculation? Do glasses of milk or protein shakes contribute in the same or comparable way to health the way water does. Or to be clear, can I subtract the amount of milk and protein drinks I consume daily from the amount of water I need to drink daily. I assume coffee is not a positive fluid contributor and should not be counted. Peace out—Davey’s the best. Thanks

  10. Drinking too much water can actually kill you. I have seen it in the news numerous times. A Scientific American article ( explains.
