Water, H2O, Adam’s Ale – whatever you call it – all life on earth whether human, animal or plant must have water to survive. Sadly, our planet is suffering from the pollution of its most precious resource in most parts of the world both on land and in the waterways and oceans.
Water covers 71% of the Earth’s surface.[i] On Earth, 96.5% of the planet’s crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies and 0.001% in the air as vapor, clouds and precipitation. Only 2.5% of this water is freshwater and 98.8% of that water is ice and ground water. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere.[ii]
Water and The Human Body:
The human body contains from 55% to 78% water, depending on body size. The average person is made up of at least 2/3 water. The brain alone is at least 85% water. Our digestive system, saliva, circulatory system and blood are all mostly water. Our joints are lubricated by synovial fluid which is almost completely water. To function properly, the body requires between 4 to 12 cups or approximately one to seven liters of water per day to avoid dehydration. The precise amount of dehydration depends on the level of activity, temperature, humidity and other factors.
Most fluids are ingested through foods or beverages other than drinking straight water. It is not clear how much water intake is needed by healthy people, though most specialists agree that approximately 6 to 7 glasses of water daily is the minimum to maintain proper hydration.[iii] Medical literature favors a lower consumption, typically 4 cups of water for an average male and slightly less for women, excluding extra requirements due to fluid loss from exercise or warm weather.
For those who have healthy kidneys, it is rather difficult to drink too much water, but, especially in warm humid weather and while exercising, it is dangerous to drink too little. People can drink far more water than necessary while exercising, however, putting them at risk of water hyperhydration, which can be fatal.[iv] The popular claim that “a person should consume eight glasses of water per day” seems to have no real basis in science. Studies have shown that extra water intake, especially up to 500 ml at mealtime was conducive to weight loss. Adequate fluid intake is helpful in preventing constipation.
If you drink a lot of water be sure to supplement it with electrolytes, available at health food stores, to keep your heart strong. Your heart beats 100,000 times a day and creates an electrical charge with every beat. An electrolyte is a substance that produces an electrically conducting solution when dissolved in water. Electrolytes carry a charge and are essential for life. All higher forms of life need electrolytes to survive. “Too much water intake will flush minerals from your blood and can weaken your heart leading to congenital heart failure.” Says Dr. Harry Elwardt, N.D.
Water Makes the World Go Around:
Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth’s streams, lakes and oceans and the fluids of most living organisms. Water refers strictly to the liquid state, but often also to its solid of ice, or gaseous state of steam or water vapor.
Fresh drinking water is essential to humans and other lifeforms even though it provides no calories or organic nutrients. Access to safe drinking water has improved over the last decades in almost every part of the world, but approximately one billion people still lack access to safe water and over 2.5 billion lack access to adequate sanitation. Some observers have estimated that by 2025 more than half of the world population will be facing water-based vulnerability.[v]
Water plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a major source of food for many parts of the world. Much of long-distance trade of commodities, such as oil and natural gas and manufactured products is transported by boats through seas, rivers, lakes and canals. Large quantities of water, ice and steam are used for cooling and heating in industry and homes. Water is used as a solvent for a wide variety of chemical substances; as such it is widely used in industrial processes and in cooking and washing. Water is also central to many sports and other forms of entertainment, such as swimming, pleasure boating, boat racing, surfing, sport fishing and diving.
Most of all, however, it is the stuff we are made of so drink some water every day! Regular chiropractic check-ups will also keep your nervous system and spinal vertebra in top condition. Make an appointment today!!
