At first glance, water doesn't seem to contribute much to your health. After all
it has no vitamins. No fibre. No protein. No carbohydrates. The truth is, water
is vital to your well-being.
75% of North Americans are chronically dehydrated. Even mild dehydration slows
metabolism, causes fatigue, reduces short-term memory, and increases existing
health challenges. Drinking the right water is even more important than drinking
more.

Water is Cheap Insurance
One of the easiest ways to help the body function optimally and remain disease-free
is to keep it well hydrated. In drinking sufficient water throughout each day,
we assist our body's ability to flush toxins and metabolic waste.
Most healthy adults need not worry about over-hydration.
Dehydrated cells are inefficient cells: when the cell is dehydrated, its membrane
becomes convoluted and the distance across the membrane increases. Substances
that must traverse the membrane of a dehydrated cell are met with greater resistance.
Oxygen and nutrients will not enter as readily; metabolic waste cannot leave
as easily. When the cell is not functioning optimally, how can the body?
Research has shown that proper hydration may minimize chronic pains such as
rheumatoid arthritis, lower back pain and colitis, as well as lower cholesterol
and blood pressure. Many health practitioners advise that if we simply drank
enough water to keep our bodies sufficiently hydrated, many of the chronic diseases
we find today would be seriously abated.

Research has also shown chronic dehydration to be the root cause of many diseases
associated with aging (e.g. arthritis, G.I. disorders, senile dementia). To
complicate the situation, our "thirst signals" decline as we become
accustomed to being dehydrated and as we age. Dehydration in the elderly can
become a real problem.
Every breath we exhale is always 100% humid. It does not matter what the relative
humidity is that day; generally in air-conditioned buildings, the air is about
10% humid. The difference comes from our water reserves. Perspiration is not
always noticed in dry climates because it is wicked away before it can bead
on your skin. Even though you may not see it, be assured that you are certainly
losing fluid reserves through sweating (as well as through urine and breath).
How do I tell if I am sufficiently hydrated?
"The best way to determine if you're getting enough water
every day is to listen to your body," says Dr. Robert Shmerling of Harvard
Medical School. "Are you excessively thirsty? Are you urinating less frequently
than normal? Are you feeling unwell? Are you dizzy when you stand up? Is your
mouth dry? While there are reasons other than dehydration that can cause these
symptoms, if you can answer NO to all these questions, then you're
probably getting enough water."
Unfortunately, many people are not aware of their own thirst! It is estimated
that in 37% of Americans, the thirst mechanism is so weak it is often mistaken
for hunger. (In one Univ. of Washington study, it was found that one glass of
water deters hunger pangs for 98% of the dieters observed in the study.)
So one of the easiest ways to tell is: The 3 Cs -- You will know you are sufficiently
hydrated when your urine is Clear, Colorless, and Copious!
How do I maintain adequate hydration levels?

Drink pure
alkaline ionized water whenever you can; thirsty or not, drink a lot and
drink often. It's a superior hydration system, and increases one's appetite
for water. One recommendation is to drink, in ounces, half your body weight
measured in pounds. |
 |
Don't count on coffee
or sodas to achieve a daily hydration goal. Because of the caffeine in coffee
and most sodas, you need to consume at least the same amount of water just
to break even. Sugar content in sodas exerts great osmotic pressure; water
is lost from the blood to make the soda dilute enough to leave the stomach. |
 |
Have a water bottle
handy at all times! Keep one on your desk at work and in your car. |
 |
Don't depend on fruit
juice - its high sugar content can dehydrate you just like soda! Mixing
equal parts juice and pure water will do the job better. |
 |
Consume the watery
fruits and vegetables: watermelon, kiwi fruit, tomato, orange, carrots,
apples, etc. These can significantly improve your hydration status. |
 |
After a single exercise
session (or a nights sleep, for that matter) any reduction in body weight
is attributable to water loss: 2 cups of water = one pound. Drink a glass
of water 30 minutes to an hour before exercising; drink another glass or
more after you're finished. |
Are you at risk?
Maintaining proper hydration is especially important for:
 |
The Active:
people who exercise strenuously, particularly in hot or humid weather. This
includes athletes, powerlifters, dancers, firemen, etc. |
 |
Desert-dwellers,
or those who live in hot, humid climates |
 |
The elderly: as we
age, the body's ability to conserve water is reduced, and
one's sense of thirst may diminish. (see below) |
 |
Anyone who is sick
with fever, diarrhea, nausea or vomiting should increase fluid intake. This
is especially important for children and the elderly. |
 |
People who take diuretics
("water pills") such as furosemide and hydrochlorothiazide must
monitor themselves closely for signs of dehydration. |
 |
Those living in houses
with forced-air heating during the winter |
 |
Singers, teachers
public speakers and other professional voice users. |

Michael 'Rocky' Katsidis, Champion Boxer
"The alkaline ionised
mineral water...has proved to be a wonderful partner in helping me move through the various stages to achieve a world championship.
The ability of alkaline water to quickly hydrate my body cells, provide dissolved oxygen, act as an antioxidant, and help metabolise lactic
acid buildup, is helping me achieve my goal of becoming a world champion" |

Marj Chipperfield, World Champion
At 82 Marj Chipperfield is a world champion. At this years World Masters Swimming championships in Canada, Marj won two gold (400m individual medley and one kilometer lake swim), two silver (200m backstroke and 100m freestyle) and one bronze (200m freestyle)
."I have been drinking alkaline ionized mineral water... for the past two years. I simply love the refreshing taste; all the other benefits of increased oxygen content, anti-oxidant abilities, rapid absorption, and its higher pH to neutralize excess acidity are all extra-added bonuses. Thank you,your water is a blessing for the young and old alike." |
Hydration and the Elderly
"Older people are more likely than others to become dehydrated because their brain underestimates how much water the body needs to remain healthy”, Australian researchers say.
Scientists from the Howard Florey Institute found that a part of the brain that predicts how much water a person needs switches off in older people before their body has been adequately replenished.
When a person is thirsty the mid-cingulate cortex increases activity, prompting the body's thirst response. This switches off when the body's need for water is satisfied.
Researchers gave salty water to 12 men aged 65 to 74 years, and 10 men aged 21 to 30, to make them thirsty. The men were then allowed to drink as much water as they wanted.
Both groups had the same level of thirst but the older group drank less than half as much water before activity in the mid-cingulate cortex was switched off, says the study, published in the journal Proceedings of the National Academy of Sciences.
Dr. Michael Farrell, a senior research officer, said decreased brain activity was part of the ageing process, and older people could no longer trust thirst sensation. "Adults should drink about 8 glasses of water per day to prevent dehydration, and physically active people may need to drink more," he said.
