Food usually accounts for 20 percent of your fluid intake, so you if you consume 2 liters of water or other beverages a day (a little more than 8 cups), along with your normal diet, you can replace the lost fluids. \nEight 8-ounce glasses of water a day. Another approach to water intake is the "8 x 8 rule" — drink eight 8-ounce glasses of water a day (about 1.9 liters). The rule could also be stated, "drink eight 8-ounce glasses of fluid a day," as all fluids count toward the daily total. Though this approach isn't supported by scientific evidence, many people use this basic rule as a guideline for how much water and other fluids to drink. \nDietary recommendations. The Institute of Medicine recommends that men consume 3 liters (about 13 cups) of total beverages a day and women consume 2.2 liters (about 9 cups) of total beverages a day. These guidelines are based on national food surveys that assessed people's average fluid intakes. \nYou can choose any of these fluid intake approaches to gauge your fluid needs. But your current total fluid intake is probably OK if you drink enough water to quench your thirst, produce a colorless or slightly yellow normal amount of urine, and feel well.

There is NO SET AMOUNT that you "should" drink in a day.\nYou'll hear a lot of bullsh!t about "8 glasses" or "half your weight in oz.", but there's NO science backing any of that.  It's all just folklore and urban myth.\n\nDrink when you're thirsty.  Period.

That's good to drink water, but what you eat and how much is more important. The calories eaten must be less than the calories burned through daily activities and exercise.

No it is not bad. In fact a grown up male should take a minimum of 3 litres of water or other fluids per day. It can be more than this but not less. read -\n\nHow much water do you need?\nEvery day you lose water through your breath, perspiration, urine and bowel movements. For your body to function properly, you must replenish its water supply by consuming beverages and foods that contain water.\n\nA couple of approaches attempt to approximate water needs for the average, healthy adult living in a temperate climate.\n\nReplacement approach. The average urine output for adults is 1.5 liters a day. You lose close to an additional liter of water a day through breathing, sweating and bowel movements. Food usually accounts for 20 percent of your total fluid intake, so if you consume 2 liters of water or other beverages a day (a little more than 8 cups) along with your normal diet, you will typically replace the lost fluids. \nDietary recommendations. The Institute of Medicine advises that men consume roughly 3.0 liters (about 13 cups) of total beverages a day and women consume 2.2 liters (about 9 cups) of total beverages a day-.

Water does provide some nourishment for the skin and prevents dryness and flakiness.  It moves to the top layer of skin through transepidermal water loss.  \nHowever, I don't believe that you should actually drink eight to ten gallons or glasses of water each day.  Drink when you're thristy.

Almost everyone agrees that water is good for you and that the biggest problem with water intake is that you don't drink enough. We have all had it drummed into us that we need to drink at least eight glasses of water a day. That it's important to drink water before and during exercise. \n\nThat coffee and tea don't count because caffeine can dehydrate our bodies. And that you can't trust your thirst as an accurate measure of when you need water since if you're thirsty you're already dehydrated. Well think again. According to a recent review in the Journal of Physiology, most of these accepted truths seem to be myths. \n\n This review looked at the scientific evidence of the 8*8 mantra � drinking at least eight 8-ounce glasses of water a day, and found that there really was none. \n\nThe claimed benefits of taking in that much water each day, including benefits for weight loss, bowels, fatigue, arthritis, mental alertness and headaches, losing weight, preventing constipation, are also mostly unsubstantiated. \n\nOther Water Myths That Are Debunked In This Article Include: \n\n\nBy the time a person is thirsty that person is already dehydrated. This in fact isn't true and the best measure of how much water to drink is your thirst. \n\nDark urine means dehydration. Again that's not strictly true either as there are many other factors that can contribute to dark urine. \n\nCaffeinated beverages dehydrate us. As you'd expect much of this is also unsubstantiated. In fact, contrary to popular opinion, a recent study has found that coffee, tea and sodas are hydrating for people used to caffeine and thus should count toward their daily fluid total. \nWhile this review focuses on the validity of the various water myths, no one seriously disputes that getting enough water is crucial. However, fears of dehydration and the constant barrage telling us we don't drink enough water, has led to a mistaken belief that the safe thing to do is to drink as much and as often as possible. But drinking too much water can be hazardous to your health. \n\n\nToo Much Water?\n \n\nThe reason why over hydrating can be dangerous is that when we consume large amounts of water when exercising, blood plasma (the liquid part of blood) increases, while the sodium concentration in the body fluids decreases, both as a result of the dilution by the water but also because sodium is lost by sweating. \n\nHyponatremia, or low blood sodium, generally happens after drinking too much plain water and can lead to adverse effects and tissue damage, and interfere with brain, heart, and muscle function. \n\n Early symptoms can be difficult to spot and include: \n\n\nConfusion \nNausea \nFatigue \nMuscle cramps \nWeakness\nMore severe symptoms can include vomiting, muscle twitching, delirium, seizures, coma and death. \n\nA new review of three deaths of US military recruits highlights the dangers of drinking too much water. Like in sports, the military has traditionally focused on dangers of not drinking enough, especially under conditions often associated with exercise and hot conditions. However, getting overzealous over the need to drink large amounts of water and over-hydrating can have deadly consequences. \n\n\nSo How Much Water Should You Drink.\n \n\nMy recommendation is to drink when you're thirsty, and if you think you should be drinking more, don't overdo it. As far as drinking water in and around exercise, I've outlined a few simple guidelines that will make sure you're well hydrated without hitting any extremes. \n\nWithin an hour or so of training, drink a few glasses of water so you start well hydrated. While training you can drink a glass or so of water for every 15 minutes you train, especially if you're sweating it out. \n\nHowever, even during times of heavy sweating don't take in more than a quart and half of water per hour.

Almost true, first off all it will hidrate you (and your skin). It will help your body get rid of impurities in your blood, kidneys, and skin. It will help your body balance salts and minerals. And help you digest your food.\n\nAll known forms of life depend on water. (Note however that some bacteria and plant seeds can enter a cryptobiotic state for an indefinite period when dehydrated, and "come back to life" when returned to a wet environment). Water is a vital part of many metabolic processes within the body, and significant quantities of water are used during the digestion of food.\n\nAbout 72% of the fat free mass of the human body is made of water. To function properly the body requires between one and seven litres of water per day to avoid dehydration, the precise amount depending on the level of activity, temperature, humidity, and other factors. However, most of this is ingested through other foods or beverages (hot tea being often used in deserts to avoid dehydration, etc.) It is not clear how much water intake is needed by healthy people. However, for those who do not have kidney problems, it is rather difficult to drink too much water, but (especially in warm humid weather and while exercising) dangerous to drink too little. People can drink far more water than necessary while exercising, however, putting them at risk of water intoxication, which can be fatal. The "fact" that a person should consume eight glasses of water per day cannot be traced back to a scientific source. The latest dietary reference intake report by the US National Research Council recommended 2.7 liters of water total (including food sources) for women and 3.7 liters for men.

Your Body can only consume up to 8 ounces of water per hr. Since your body can only consume this amount there is no othere place for the liquid to go other than to have your body dispose of it. That is why when people drink a lot, the go to the bathroom more often.

I try to drink at least two litres.  My doc told me the best guideline is to take your weight in pounds, divide that by two, and drink that many ounces per day.  That means if you weigh 120, you should drink at least 60 oz. each day.\n\nTo make it easier, I have two Nalgene bottles that I fill at the start of each day - my goal is to finish both before I finish work for the day.  Then I know I've reached my goal.

Normally 8 cups is recommened...not all at once either. Drink it over the course of the entire day.\n\nHowever, if you exercise, you should increase this amount to 10-12 cups.

Water in such large amounts is poison!  \n\nIt causes a condition called hyponatremia.  Drinking so much water (you're talking about half a gallon every 15 minutes- that's 2 gallons an hour, or 32 gallons in a 16 hour day) causes your blood to become diluted, which interferes with your heart, brain, and muscle function. Untreated, it can lead to comma or death. \n\nThis is NOT a safe way to increase your metabolism.\n\nIn a healthy adult, the kidneys can process a MAXIMUM of  4 gallons (512 oz) per day.  However, even that much water will not increase your metabolism.  Only exercise can increase your metabolic rate.

2 Litres, which includes all the liguid you drink in 24 hours,  such as water, tea, coffee etc. Any more can be bad for you as you then start to lose electrolytes from the body. So the old '2 litres' of water per day is wrong, unless you only drink water.

the MINIMUM liquid that a person should take is about 2 to 2.5 liters a day. it includes water, other beverages and the food that you eat. 2 gallons is not much as long as your body can accomodate that amount.\nare you practicing "water therapy"?
