How much water should a person drink a day
Answers to How much water should a person drink a day
A person should drink 2 litres of water a day. Increase it to 3 liters in the hot months.
If you're not drinking enough water per day, you could end up with excess body fat, poor muscle tone, digestive complications, muscle soreness -- even water-retention problems.
Next to air, water is the element most necessary for survival. A normal adult is 60 to 70 percent water. We can go without food for almost two months, but without water only a few days. Yet most people have no idea how much water they should drink. In fact, many live in a dehydrated state.
Without water, we'd be poisoned to death by our own waste products. When the kidneys remove uric acid and urea, these must be dissolved in water. If there isn't enough water, wastes are not removed as effectively and may build up as kidney stones. Water also is vital for chemical reactions in digestion and metabolism. It carries nutrients and oxygen to the cells through the blood and helps to cool the body through perspiration. Water also lubricates our joints.
We even need water to breathe: our lungs must be moist to take in oxygen and excrete carbon dioxide. It is possible to lose a pint of liquid each day just exhaling.
So if you don't drink sufficient water, you can impair every aspect of your physiology. Dr. Howard Flaks, a bariatric (obesity) specialist in Beverly Hills, Calif, says, "By not drinking enough water, many people incur excess body fat, poor muscle tone and size, decreased digestive efficiency and organ function, increased toxicity in the body, joint and muscle soreness and water retention."
Water retention? If you're not drinking enough, your body may retain water to compensate. Paradoxically, fluid retention can sometimes be eliminated by drinking more water, not less.
"Proper water intake is a key to weight loss," says Dr. Donald Robertson, medical director of the Southwest Bariatric Nutrition Center in Scottsdale, Arizona. "If people who are trying to lose weight don't drink enough water, the body can't metabolize the fat adequately. Retaining fluid also keeps weight up."
The minimum for a healthy person is eight to ten eight-ounce glasses a day," says Dr. Flaks. "You need more if you exercise a lot or live in a hot climate. And overweight people should drink in an extra glass for every 25 pounds they exceed their ideal weight. Consult your own physician for their recommendations.
At the International Sports Medicine Institute, we have a formula for daily water intake: 1/2 ounce per pound of body weight if you're not active (that's ten eight-ounce glasses if you weigh 160 pounds), and 2/3 ounce per pound if you're athletic (13 to 14 glasses a day, at the same weight).
Your intake should be spread throughout the day and evening. You may wonder: If I drink this much, won't I constantly be running to the bathroom? Yes. But after a few weeks, your bladder tends to adjust and you urinate less frequently but in larger amounts.
And by consuming those eight to ten glasses of water throughout the day, you could be on your way to a healthier, leaner body.
The human body is composed of 25% solids and 75% water. Brain tissue is said to consist of 85% water.
It has become a practice to regard a "dry mouth" as a signal of body water needs, which is further assumed to be well-regulated if the sensation of "dry mouth" is not present. A dry mouth is the last outward sign of extreme dehydration, however. Damage occurs to the body at a persistent lower level of hydration. Because of a gradually failing thirst sensation, the body becomes chronically and increasingly dehydrated.
Signals of dehydration can be any of the following symptoms:
Heartburn, stomach ache
Non-infectious recurring or chronic pain
Low back pain
Mental irritation and depression
Water retention ( ironic but true!)
Further problems often develop when the sensation of thirst urges an intake of water, and instead, soda pop, coffee, or alcohol-containing beverages are taken to quench the thirst. While these beverages contain water, they are actually dehydrating fluids. Not only do they eliminate the water contained in them, but they also cause you to lose further amounts of water from your body's reserves!
Daily Water Requirements: Drink 50-75% of your body weight in ounces.
Sedentary people: 50%;
Active people: 75%
Pounds of body weight - 150 lb.
Water requirement from above (75% of body weight for an active person) - 112.5 oz.
Add for dryness of climate - + 16 oz.
Add for strenous exercise - + 16 oz.
Total per day 144.5 oz.
Divide by the number of hours you're awake to find your hourly water requirement: 144.5 ÷ 16 = 9 oz.
Therefore, a 150-pound active person who works out should drink 9 oz. of water for each hour awake.
How 8 Glasses a Day Keeps Fat Away
Incredible as it may seem, water is quite possibly the single most important catalyst in losing weight and keeping it off. Although most of us take it for granted, water may be the only true "magic potion" for permanent weight loss!
Water suppresses the appetite naturally and helps the body metabolize stored fat. Studies have shown that a decrease in water intake will cause fat deposits to increase, while an increase in water intake can actually reduce fat deposits. Here's why: The kidneys can't function properly without enough water. When the kidneys don't work to capacity, some of their load is dumped onto the liver. One of the liver's primary functions is to metabolize stored fat into usable energy for the body. If the liver has to do some of the kidney's work, it can't operate at full throttle. As a result, it metabolizes less fat, more fat remains stored in the body, and weight loss stops. Drinking enough water is the best treatment for fluid retention. When the body gets less water, it perceives this as a threat to survival and begins to hold on to every drop. Water is stored in extra cellular spaces (outside the cells). This shows up as swollen feet, legs and hands. Diuretics offer a temporary solution at best. They force out stored water along with some essential nutrients. Again, the body perceives a threat and will replace the lost water at the first opportunity. Thus, the condition quickly returns. The best way to overcome the problem of water retention is to give the body what it needs.PLENTY OF WATER. Only then will the stored water be released. If you have a constant problem with water retention, excess salt may be to blame. Your body will tolerate sodium only in a certain concentration. The more salt you eat, the more water your system retains to dilute it. But getting rid of un-needed salt is easy - just drink more water. As it's forced through the kidneys, it takes away excess sodium. The overweight person needs more water than the thin one! Larger people have larger metabolic loads. Since we know that water is the key to fat metabolism, it follows that the overweight person needs more water. Water helps maintain proper muscle tone by giving muscles their natural ability to contract and by preventing dehydration. It also helps to prevent the sagging skin that usually follows weight loss - shrinking cells are buoyed by water, which plumps the skin and leaves it clear, healthy, and resilient. Water helps rid the body of waste. During weight loss, the body has a lot more waste to get rid of - all the metabolized fat must be shed. Again, adequate water helps flush out the waste. Water can help relieve constipation. When the body gets too little water, it siphons what it needs from internal sources. The colon is one primary source. Result? Constipation. But, when a person gets enough water, normal bowel functions returns. So far, we've discovered some remarkable truths about water and weight loss:
The body will not function properly without enough water and can't metabolize stored fat efficiently.
Retained water shows up as excess weight.
To get rid of excess water you must drink more water.
Drinking water is essential to weight loss. How much water is enough??
On the average, a person should drink eight 8-ounce glasses every day. That's about 2 quarts. However, the overweight person needs one additional glass for every 25 pounds of excess weight. The amount you drink also should be increased if you exercise briskly or if the weather is hot and dry. Water should preferably be cold - it's absorbed into the system more quickly than warm water. And some evidence suggests that drinking cold water can actually help burn calories. When the body gets the water it needs to function optimally, its fluids are perfectly balanced. Once this happens you have reached the "breakthrough point". What does this mean?
Endocrine-gland function improves.
Fluid retention is alleviated as stored water is lost.
More fat is used as fuel because the liver is free to metabolize stored fat.
Natural thirst returns.
There is loss of hunger almost overnight.
If you stop drinking enough water, your body fluids will be thrown out of balance again, and you may experience fluid retention, unexplained weight gain and loss of thirst. To remedy the situation you'll have to go back and force another "breakthrough".
