How Much Water Do You Need?

Experts offer a range of answers to this question, from “Drink only when thirsty,” to “Drink enough to replace the fluids you lose through breathing, perspiration, and elimination,” to “Drink the amount I recommend.” For example, the Food and Nutrition Board of the Institute of Medicine recommends that women drink about 2.2 liters (nine 8-ounce glasses) of water a day, and men about 3 liters (thirteen 8-ounce glasses).



Here are my own guidelines, based on years of observation of myself, my patients, and people in gyms; on talking to doctors I respect; and on research. (One liter equals 1.06 quarts; so for all practical purposes, liters and quarts are interchangeable. If you’re measuring in liters, you’ll drink a very small amount more, which can only help.)

  • Men less than 200 pounds: 2.5 quarts per day
  • Men more than 200 pounds: 3 quarts per day
  • Male athletes more than 200 pounds: at least 3.5 quarts per day
  • Women less than 150 pounds: 2 quarts per day
  • Women more than 150 pounds: 2.5 quarts per day
  • Women athletes more than 150 pounds: 3 quarts per day


These amounts will make you well hydrated without your running any risk of drinking too much water, which can be a problem, too. Remember, though, that the preceding numbers are approximations. The amount of water you need changes from day to day based on how much you perspire, the water content of your food, the amount of alcohol you drink (alcohol is dehydrating), and your activity level (if you’re exercising when it’s hot out, you need more water). But the minimum amounts of water anyone should drink are as follows:

  • Men of any age, in any condition: 2 quarts a day
  • Women of any age, in any condition: 1.5 quarts a day


Many of my patients balk at this prescription. A common complaint is, “I’m not used to drinking this much water—I’m gagging on it!” An even bigger one is, “I have to get up at 4 A.M. to urinate!” And I respond, “So do I, but I do it anyway.” People ask me why my skin looks so good and why I’m so healthy. The main reason is that I drink enough water, and peeing is a very small price to pay for that. As far as I’m concerned, it’s no price at all. What price would you set on being healthy and pain free? Is it really such an imposition on your life to urinate a few extra times a day, considering the benefits? I call hydration and the other two key practices that this article recommends “lifestyle changes” because they do involve a certain level of adjustment. As I say to my patients, “Get used to it.” If you’re like most people, you’re dehydrated and don’t even know it. After a long period of chronic dehydration, the body loses its ability to detect whether it’s thirsty. So you need to deliberately drink more than you may feel you need. You’ll find that as your body grows accustomed to taking in more water, your water-detection mechanism kicks back into gear and your desire for water actually increases. What may seem at the beginning like much too much to drink will become easy to swallow after as little as two weeks. In fact, it will feel normal and necessary. Expect your body to request more water as it becomes more hydrated. When it starts regulating water as it was intended to, you’re truly well hydrated.

Getting hydrated brings a couple of nice bonuses. A big one is the change in your face. Your skin will look smoother and more youthful because of the water underneath. When I put Rick on hydration, he was fifty-four. After three weeks, his wife swore he looked ten years younger, and he did look fantastic. His skin was much softer and smoother; some of his wrinkles had smoothed out. Another great side effect of hydration for most people is an increased ability to lose weight. Research has shown that bringing more water into the body cells actually increases the rate of metabolism, thus helping burn calories.

Generally, it takes about six weeks to become fully hydrated. But I don’t want to make you wait that long to get to the stretches, so I’m only asking you to do ten days of preparation. As you embark on your stretch program, you’ll continue to hydrate, so by the end of six weeks of stretching, you’ll have been drinking water for about eight weeks and should be fully hydrated.

To enhance the benefits of hydration, I suggest that you add trace minerals to your diet. The body needs tiny amounts of a variety of minerals, including chromium, vanadium, manganese, iron, copper, and zinc, to function properly. These minerals are the spark plugs of water, facilitating its chemical reactions. An excellent way to get these minerals is to use Celtic or Himalayan salt in your food instead of regular table salt. These types of salt retain naturally present minerals that have been refined out of table salt, which contains excessive sodium. The sodium content of Celtic and Himalayan salt (available in health food stores or online) is lower than that of table salt, so it’s more suitable for people with high blood pressure.

Important: if you have high blood pressure, consult a complementaryintegrative medical doctor about using any form of salt.

A note for athletes: there’s been a lot of publicity about a condition called hyponatremia. News stories have focused on runners who developed it after distance runs, when sweating combined with drinking large amounts of water diluted the amount of sodium in their blood. Symptoms include nausea, confusion, cramps, weakness, and in severe cases, coma or even death. Hyponatremia usually occurs when someone has exercised intensively for more than sixty minutes while consuming more than 1.5 quarts of water per hour.


Most people don’t have to worry about hyponatremia at all, and athletes can easily avoid it by drinking 2 ounces every fifteen minutes while exercising and then drinking more when they finish their workout. Don’t let concerns about overconsuming water interfere with following my extremely beneficial hydration program.
