Think You're Drinking
Enough Water?
By Leroy R. Perry, Jr.
Condensed from PARADE
If you're not, 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.
Calculating Your
Own Daily Water Requirements
By Dr. Thomas Stearns Lee
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
-
Headache
-
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%
Example Calculation:
| Pounds of body weight Water
requirement from above (75% of body weight for an active person)
Add for dryness of climate
Add for strenous exercise |
150 lb. 112.5 oz.
+ 16 oz.
+ 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.
This is only an estimate. "Actual milage may
vary."
