WATER & YOUR HEALTH
Water and Our Health
Did you know:
- Water comprises 50 to 70 per cent of an adult's
total body weight, and without regular top-ups, our
body's survival time is limited to a matter of hours
- You can survive without food for 60 to 120 days
depending on body fuel stores, but can only survive
without water for a maximum of 2 to 7 days depending
on temperature and exercise.
Factors that increase our requirement for water include:
- Caffeine in coffee, cola and alcohol has diuretic
effect causing fluid loss from the body
- Dry environments such as offices, with air control
systems and lots of electrical equipment.
- Exercise, increasing body heat, thereby activating
the cooling process, sweating. To find out more about
requirements during exercise.
Health Benefits of Water
Water is vital to the body for a number of core functions:
- Aids fat metabolism – water is they key to
fat metabolism; the more fat you have, the more water
- Aids kidney function – the body is constantly
producing toxins as a byproduct of normal cell function.
In the kidneys, these toxins are dissolved in water
so the body can filter them out through urination.
Insufficient water leads to toxic offload from the
kidneys to the liver.
- Maintains blood volumes - water is necessary for
the production of new blood cells. Blood volume is
determined by the amount of water and sodium ingested,
excreted by the kidneys into the urine, and lost through
the gastrointestinal tract, lungs and skin. To maintain
blood volume within a normal range, the kidneys regulate
the amount of water and sodium lost into the urine.
- Aids muscle tone and functioning
- Keeps skin hydrated, and functioning to prevent
clogged poors and withering
- Aids endocrine gland function
- Transports essential nutrients throughout the body
and rids the body of waste
- Acts as a lubricant for the body, moistening eyes,
mouth, nose, and skin
- Helps regulate body temperature, especially in warm
- Helps prevent constipation
- Helps medications to work - assists absorption
- Boosts metabolism when drunk cold [we burn 2 calories
per glass as we warm it up to body temperature]
Signs of Dehydration
Whilst thirst is the obvious symptom of dehydration,
many other signs tell us we need more fluids.
- Dry mouth, swollen tongue
- Rapid pulse, increased breathing rate
- High body temperature, flushed skin
- Dizziness, Delirium
- Muscle spasms and muscle weakness
Water & Toxins
Water is a powerful cleanser, flushing many toxins
from the body in urine. Water may also be used in healing;
often found to contain high levels of specific minerals
that may help to relieve the condition. 'Holy' or 'blessed'
water, either from sacred sites or blessed by spiritual
teachers have prompted claims of miracle cures.
Sources of Water in the Body
The body gets its water from three sources:
- drinks, either plain water or as part of other
- solid foods, especially fruits and vegetables.
- as a by-product of chemical reactions within the
The average adult should consume 2.5 litres of water
per day. Of this, 1.8 litres - the equivalent of six
to seven glasses of water per day - must be obtained
directly from beverages. This should be increased during
periods of hot weather or during and after periods of
Water is the major ingredient of all drinks: carbonated
and still drinks are 65 per cent water, diluted squashes
are 86 per cent water (after dilution) and fruit juices
are 90 per cent water. But drinking plain water is still
the most effective way of replacing lost fluids.
There are two types of bottled water:
- Spring water - collected directly
from the spring where it arises from the ground and
must be bottled at the source. Sources of spring water
must meet hygiene standards, but may be treated in
order that they meet limits set on pollution.
- Mineral water - emerges from under
the ground, then flows over rocks before it's collected,
resulting in a higher content of various minerals.
Unlike spring water, it can't be treated except to
remove grit and dirt. Different brands of spring and
mineral waters will have differing amounts of minerals
depending on their source. Most Governments require
all minerals in natural mineral water must be listed
on the label.
Local Water Supply
Supplying safe drinking water is the most important
task for water authorities. Most tap water is adequate
to meet hydration needs. Whether you think the local
council standards meet your needs is your decision.
In addition, bacteria in the water mains are another
threat, so water suppliers try to ensure there's a residue
of chlorine to protect the water on its way from the
treatment plant to your home. Often contaminants are
removed, but chemicals such as chlorine remain, altering
the purity and taste of the water. This is where home
purifiers provide a benefit.
