How much water should you drink in a day?


I hope this isn’t a silly question, but it’s one of those that has varying opinions – how much water should you drink in a day? I don’t drink enough but I need something to aim for. I read an article about a woman who drank 3l of water a day for 4 weeks and she looked so different after. Better for it!

  1. Everybody is different, so why place some sort of arbitrary number like 1/2 your weight in oz? Or whatever the number is. Drink when you are thirsty. Stop drinking when you aren't thirsty. That is a fantastic goal.

  2. When we are thirsty, our bodies are looking for two elements:
    o H2O, and
    o the 90+ minerals that our Ancestors took for granted…

    I'm with Scott ^^^^ once again… ๐Ÿ˜‰

  3. Half your weight in ounces. So if your 100lbs you'd drink 50 oz. also if you are chronically dehydrated you should put 1/8 tsp sea salt dissolved on your tongue for every 16 oz of water.

  4. I tell people 1/2 your body weight in ounces not to exceed a gallon. I use this as a goal for them to help them be mindful of drinking throughout the day. Also, its important to sip the water, not gulp it down. The body can only process 4oz every 15 minutes. It serves no purpose to chug water at the end of the day to meet a goal.

  5. I agree that you really cannot be arbitrary but I also think that many people do not recognize thirst and often substitute food for water

  6. Earlier in this post, I created a link to an article published by Dr. Sandra Fowkes Godec. She is a preeminent expert on hydration, and the multitude of myths on dehydration. You should all be SCRAMBLING to get your eyes on this paper. Please, follow the link to learn some science:

  7. Not everyone can drink when thirsty or even only eat when hungry. Personally my brother has prader willie syndrome. All our food and drinks besides water were locked up. It was so much work to even make a sandwich I had to unlock n remember three different combination lock codes! I think it just wasn't worth the hassle n I kinda never learned how to listen to my own basic needs ๐Ÿ™

  8. At least half your weight in oz per day, preferably more.

    Can you provide a valid scientific study to support that much bally-hooed cry for 1/2 your body weight in water?!?…

    The issue is MINERALS — NOT H2O… ๐Ÿ˜‰


  10. No! Half you weight in ounces of water ๐Ÿ™‚

  11. Like I need 56 ounces believe it is. It's not anything crazy really ๐Ÿ™‚

  12. Hey Morley Robbins please pass the seaweed snacks sitting on your desk…. LOL

  13. But ONLY if you promise to pass 'em back!~ MJ Hamp

  14. 1/2 your body weight in ounces is a reasonable goal to regain hydration and to be able to listen to your body's signals for thirst. Most people are dehydrated and don't recognize the signals before they reach that point. Once a person is able to recognize their body's signals, certainly, they can personalize the intake amount. Additionally, if you are only intaking what your body can process at a time, you will not throw your electrolytes off or have frequent urination.

  15. So… Maybe another silly question… I drink when I'm thirsty (or think I am) and most days I end up drinking only 1 or 2 glasses of water…. Sometimes l drink less than that. Does this mean I am always dehydrated? I know I should drink more, but it has been a lifelong struggle for me. As a child I almost never drank any water… only milk.

  16. "Cocaine use in the UK is now so common that traces of the drug can be found in our drinking water, tests show. Inspections of tap water at four different sites found a metabolised form of the illegal drug, which showed it had already passed through the human body.
    The levels were so low that they posed no danger to health, but come as a startling indication of how widespread drug use has become, British Daily Mail reports." For goodness sake. Will the madness never end??

  17. When you are thirsty, you are already dehydrated. Many experts say half your weight in ounces and add minerals back to the water.

  18. Moving to the UK! lol won't be tired any more LMBO

  19. Haha you're welcome to!

  20. Maybe this site will be of interest to you Julia. "The daily minimum requirement of water you should drink everyday is the amount that equals the quantity you lose every day. According to the World Health Organization (WHO) and the European Food Safety Authority (EFSA), the adequate total daily water intake is about 3 liters (or 13 cups) for adult males and 2.2 liters (or 9 cups) for adult females. However, our body's hydration needs are not constant; they are affected by everyday changes in diet, weather conditions, diseases, exercise levels, etc."

  21. My nutritionist says no less than 64 oz.

  22. Bare minimum is half your body weight in ounces. That would be 65oz for me but I feel way better when closer to 100oz. I add a pinch of pink Himalayan sea salt or Celtic seas salt to my water.

  23. When I arise,I drink lemon squeezed in water.(Then,Ruth Longs power drink.)I drink whenever I feel the need.There is an unhealthy condition caused by overimbiding water.Somebody here probably knows the name of it.

  24. I drink about 2-2.5 liters (8-10 cups) of water daily just with fresh Lemon juice and pich of Himalayen Salt. Plus some Tea, Coffee and Soup. And in the Summer and Gym/Sauna I will drink additional at least 1 liter (4 cups).

  25. Water alone will draw minerals out of the body. To get hydrated you need to ingest mostly water with minerals…drops of a mineral product, lemon, pinch of Celtic sea salt, etc. if you consume a lot of minerals in food (salt and other natural forms) you can be ok with plain pure water. But just chugging lots of pure water without good salts, is not healthy…it is mineral depleting.

  26. Thank you Jean Woodard Bentz!

    Also, a FAAAAR better source of hydration is FAT!…


  27. Fat is hydrating?

  28. Common sense tells me that what you eat would determine how much water you need to drink. My dogs know that naturally. ๐Ÿ˜‰

  29. Drink the equivalent of half your body weight in oz. For example, I weigh 120 lbs. I drink 60 oz. of water/day. You can also gauge by the color of your pee. Aim for colorless or light yellow. I add a pinch of Himalayan pink salt in my water.

  30. Patrick Boyle Your thought, "if you are thirsty, you are already dehydrated" is perhaps one of the biggest misnomers out there about hydration. It is simply not true. You should read the link I provided in this thread about dehydration myths so you quit spreading dangerous information.

  31. Constance Moerman Since when do we listen to the WHO and the EFSA for good info about nutrition? Drink water when you are thirsty. Quit drinking when you are not thirsty. This is the correct recommendation for hydration.

  32. 1/2 your body weight in ounces.

  33. I drink a gallon a day, which is near my body weight in ounces. However, it's because I train hard. (Don't worry I supplement minerals and have them monitored by my Dr) Sometimes your needs vary based off activity IMO. just watch your pee. Lol.

  34. yes, everyone should watch this!!!!

  35. Depends on the season, the amount of supplements you're taking, breastfeeding/pregnancy, activity level, climate… in general at least 1/2 your body weight in ounces ๐Ÿ™‚

  36. The "social construction of reality" does NOT = TRUTH!…

    Can ANYONE provide a scientific, research-based article documenting the much-ballyhooed belief we that need to drown ourselves in H2O?!?…

    Forgive me, but I AIN'T buying it… In large part because ALL the other nutritional "truths" that have shaped our belief systems have turned out to be nothing but nutty "myths!"

    I'm anxiously awaiting objective PROOF — NOT Mo' Opinion… ๐Ÿ˜‰

    A votre sante!

  37. Good point Scott

  38. Miriam Wiener
    Dr. Batman was entirely silent on the role of minerals in his work… I totally bought his thesis up until ~6 yrs ago, when I learned about the metabolic spark plugs, aka, minerals, that run the body…

  39. My nutrition mentor in the early 90's (Japanese) felt exactly as you do Morley, that we drink far too much in America and it's making us overly "yin" (flaky, floaty, unable to focus, mentally weak, cravings, yin-type diseases). He taught moderate fluid intake – never with meals – and usually in the form of some sore of mineral broth or tea. I'm somewhere in the middle nowadays having had a number of pregnancies, breastfeeding, living in a very dry climate, exercising, taking more supplements than they did in previous generations. But I hear you – it's a great discussion ๐Ÿ™‚

  40. Miriam Wiener
    That's great to hear — across the board!…

    How 'bout we BOTH declare Victory!… ๐Ÿ˜‰

    Have a great New Year and thanks for sparring with such passion and conviction…


  41. too much water actually worsens my adrenal fatigue

  42. I drink enough water to take my soo so many supplements.. and I check my scalloped tounge if they have smoothen out.. It means then that I'm hydrated and that my supplements are not collecting and slowing down my liver..

  43. Scott Harris, labeling my advice as dangerous? Really? I guess we classify the word dangerous differently. Many people die by slipping and falling but I wouldn't classify walking as dangerous, maybe you do. I think we can debate without the dramatic and misplaced annotations.

  44. Our bodies are all slightly different. the "ideal" amount of water can vary from one person to another, or even the same person at different times.

  45. Morley, I agree about the drowning ourselves in H2O myth. The "8 glasses a day" was a totally arbitrary #. I recently realized that I was probably not getting enough H2O and experimented with measuring & drinking approx 1 1/2L. (Since I consume plenty of nutrient-dense food, I am sure I don't need a full 2L.) I definitely noticed an improvement in my joints as well as in my appearance. Look a bit younger ๐Ÿ™‚ Once upon a time I drank a gal/day and that was way too much.

  46. 1/2 of what i weigh; that's how much water i drink daily. if not more.
