WATER, HUMAN SURVIVAL, HEALTH AND DISEASES
Introduction:
Water evolution and history: The water (H2O) Water has been called “mater and matrix” of life.
Water is the most abundant substance on this earth.
Basic knowledge
Definition: The water is the colorless, transparent liquid
occurring on earth as rivers, lakes, oceans, etc. and falling from the clouds as rain: chemically a compound of hydrogen and
oxygen, forming ice at 32 degree F (0 degree C) and boils, forming steam at212 degree F (100 degree C). Water has the neutral
pH at 7.Water is the best – known ionizing agent called the universal solvent can form either as acid by combine with
nonmetallic oxides or form bases by react with metal oxides
75 % of the earth’s surface
is covered by water
The oceans contain 97.5 % of the earth’s water, the land 2.4 %
Only 1 % of the earth’s water is available for drinking; 2% is frozen
History of water: Where the water came from? Earth has a lot
of water. 75 % of earth’s surface is covered by water. No one knows for sure why and how. There are many theories.
1.
Water vapor formed since the earth was cool down from cosmic dust
that lumped together to form larger and larger particles that gradually solidify since 4.6 Billion years ago
2.
.The oceans were deposited by comets impacting the newly formed earth
(the late-veneer hypothesis).
3. Earth already covered with ice but located far from present location (1 astronomical units) away from the sun (4 astronomical
units) eventually moved to present location in the inner solar system 4.6 billion years ago.
Water regarded by the ancient philosophers
as a basic element until the latter half of the 18th century. French chemist Antoine Laurent Lavoisier proved that
water was not an element, but a compound of oxygen and hydrogen.
Water in life: Water is the major constituent of living matter. From 50 to
90 percent of the weight of living organism is water. Without water there will be no live on this earth.
Properties of water that importance for life
Adhesion: As a Biological fluids
act as aqueous solutions of electrolytes
Cohesion: Water flows forming habitats and a matrix
for biological molecules
Imbibition : Embryo within seed absorbs water, swelling and bursting
through seed coat
High heat capacity: Water regulates constant internal body temperature
High heat of vaporization: Water evaporation (sweating) functions as cooling mechanism
Drinking water
As mention above, from 50
to 90 percent of the weight of living organism is water. The adult human body weight is composed of approximately 67 % water,
the brain 75% and the skin composed of 70 % water, Blood is 83% water and the lungs are 86 % water, the eyes 95%.
Ideally we need to drink 1 quart (4 cups or 32 oz) of water per 50 lbs body weight or at
least EIGHT 8 oz glasses per day everage (64 oz/d) or easily to remember method is 50% in ounces of bodyweight in pounds.
Minimum for everage water intake for adult is 64 oz./day
Better is 50% of body weight (lbs) in ounces( 75 oz. for 150 lbs person)
The best is 32 oz. per 50 lbs bodyweight( 96 oz. for 150 lbs person)
The best drinking water should be mineral water, especially high in Magnesium without heavy metals without chlorine, fluoride and microorganisms. You can use TAPWATER but need
the WATER FILTERS. Two better brands are PUR and BRITA. Ideally all water for personal uses should be filtered including for
bath and shower.

How to drink water:
The 10 commandments of good hydration
1. Drink 1/2 ounce daily for every pound you weigh. A 150lb person drinks 75 ounces, or approximately
2.5 quarts. One glass every hour is a good rule of thumb.
2. Avoid diuretic
beverages that flush water out of your body, such as caffeinated coffee, tea, soda pop, alcohol or beer.
3. Drink more water and fresh juices to maintain hydration during
illness and upon recovery. Illness robs your body of water.
4. Start your day with ½ to 1 quart of water to flush your digestive tract and rehydrate
your system from the overnight fast.
5. Drink water at regular intervals throughout the day. Don't
wait until you're thirsty. Thirst indicates an already present deficiency.
6. Get in the habit of carrying a water bottle with you or keep one in
the car or on your desk. Convenience helps. Stuff it in your shoulder bag or waist pack water bottle pocket. Hiking suppliers
have a nice selection of water-bearing belt packs and accessories.
7. Make a habit of drinking water. According to a survey, the reason most people don't drink as much
as they know they ought to, is lack of time or being too busy. Decide to drink water before every meal. Set objectives for
yourself such as drinking before you leave the house, and first thing upon your return, or before you start work. Take water
break instead of coffee breaks. Fill a size glass you can finish or gauge yourself by the number of water bottles you drink
during the day.
8. Increase
your drinking when you increase your mental activity level; your stress level; your exercise level.
9. Drink the purest water available.
10. Perspire. Exercise to the point of perspiration or enjoy a steam bath. Sweat cleans the lymphatic system and
bloodstream. It is one of the best detoxification avenues available to us. Do sweat and do drink plenty of water afterwards
to replace the loss of fluids. Drink more in hot weather.
