=WATER FOR GOOD HEALTH=



INTRODUCTION
There is no life without water. Most scientists believe that life itself began in water. Your body has two-third water. People worship raingods for having abundant water for drinking, household, agricultural and industrial purposes etc.Water is a compound containing molecules, each of which is made up of two atoms of hydrogen and one atom of oxygen bonded together. (H-2-O!) Across a large proportion of the Earth it's in liquid form, which is convenient because humans need to drink it. Though at the poles it is a solid called ice, it can also evaporate to form water vapor. Water vapor then rises to create clouds, which eventually cause rain.

IMPORTANCE OF WATER
An individual requires oxygen, water and food for the survival. Water is the most common substances on the eater. It covers more than 70 percent of earth's surface. Water is found in oceans, rivers, lakes and under the soil. It is also found in the air you breath in. Water is used for drinking, cooking, cleaning, bathing and to carry away the wastes. The body water needs are secondary only to oxygen. One cannot live long in the absence of water.

FUNCTIONS OF WATER IN THE BODY
1) Water Protects Your Tissues, Spinal Cord, and Joints. 2) Water Helps Your Body Remove Waste. 3) Water Aids in Digestion. 4) Water Prevents You From Becoming Dehydrated. 5) Saliva in the mouth is largely composed of water. 6) Water is good lubricant that facilitates of joints to some extent. 7) Body temperature is maintained with water.

HOW MUCH WATER DO YOU NEED?
There's no hard and fast rule, and many individuals meet their daily hydration needs by simply drinking water when they're thirsty, according to a report on nutrient recommendations from the Institute of Medicine of the National Academies. In fact, most people who are in good physical health get enough fluids by drinking water and other beverages when they're thirsty, and also by drinking a beverage with each of their meals, according to the Centers for Disease Control and Prevention. If you're not sure about your hydration level, look at your urine. If it's clear, you're in good shape.

QUALITIES OF DRINKING WATER
1) Drinking water should be clear. 2) It should be free of harmful bacteria. 3) It should have no objectionable taste or odour. 4) It should be pleasant to taste. 5) It should be fit for use in foods and beverages. 6) Water should be neutral having pH value.

Water in its neutral state seldom has all these qualities. One has to be sure of the quality of water in order to safeguard against water-borne infections.

WHY WATER IS IMPORTANT TO CELL
Of the important biological molecules only the non-polar lipids (fats and oils) and large polymers (e.g. polysaccharides, large proteins and DNA) do not dissolve. The water acts as a solvent for chemical reactions and also helps transport dissolved compounds into and out of cells.

WATER IN HUMAN
Water is vital to human biology, and indeed, all biology on Earth. We currently believe that the presence of liquid water is an important requirement for the development of life, to the point that it's the main thing we're searching for in our attempts to find life elsewhere in the solar system.

But why exactly is it important to human biology? There are five main functions of water in the human body: cell life, transport, chemical reactions, temperature regulation, and waste excretion.

Cell life is based on the fact that cells have water inside them. Water is used to transport nutrients to cells and within cells (intracellular). If cells don't get nutrients including vitamins, minerals and sugars, they die.

ORAL REHYDRATION SOLUTION
Dehydration can lead to death. Addition of little salt and sugar helps in controlling and maintaining the electrolyte balance in the body. This salt, sugar and water solution is called oral rehydration solution and has a tremendous power to save the patient from dying. It is commonly known as Jiwan Rakshak Ghol.It can be very conveniently made by the mothers and the person attending to the patient to control dehydration.
