We as humans depend on water to keep our right body temperature, as a transporting system, and to supply us with nutrients that it carries such as minerals, salts, and elements with which all of these things combined also help heal us and digest food.  In order for our bodies to function the right way, water is like a lubricant for all of our joints. It also keeps our eyes and our mouths moist. The older we get the more we need to drink water. The average person should be drinking at least 64 ounces of water a day. If you are a heavy tea, coffee or alcohol drinker then your body needs to intake more water because those are all diuretics and they dehydrate you of all your water.

The human race depends on our water sources and with the growing population and everything that goes with it, our water is becoming more and more scarce.

It is postulated that oceans evolved in the very beginning. The searing heat and the atmospheric temperatures that had grown considerably began to decrease with the formation of this vast aqueous medium, eventually cooling down the primordial planet thus providing optimal conditions for the procreation of life.

All early civilizations known to man have flourished because of the presence of water. All civilizations have been founded historically in places that abound with this precious liquid. The Mesopotamian civilization, known as the “cradle of civilization” was situated between the Tigris and the Euphrates. The Indus Valley Civilization thrived and flourished because of the presence of the Indus. The great Egyptian Empire was founded on the banks of the river Nile.

Water is very important – it has a major impact on life. It is critical for the sustenance of life. Water is known as the universal solvent. All metabolic processes need water. Propagation of organic minerals and salts in all life forms takes place in an aqueous medium as water is capable of dissolving almost all solutes, maintaining a neutral pH level and increasing enzymatic action. Water plays a central role in the process of photosynthesis. The cells in plants harness the sun’s energy and convert this energy into food and release oxygen. This cannot happen unless water molecules are broken down into its constituents. The sun’s energy is tapped and is used to split up water molecules into hydrogen and oxygen. This hydrogen then reacts with CO2, to form glucose and oxygen.

Water is very important in all walks of human life. Agriculture is dependent on irrigation, potable drinking water is necessary for human survival. Trade was carried on in waterways and entire civilizations have thrived because of the presence of water. Water therefore is important for the genesis of life and its sustenance.

Sweating is not as simple process as it seems to be. A whole system of sweat producing glands is there in our body and to keep the sweating process functioning about two million sweat glands are present in our body. These sweating glands are categorized into two groups including Eccrine and Apocrine. Now you were thinking that why these glands are divided into categories if both secrete water and salt. The reason is that both types are different from each other on the basis of their location, smell production and salt proportion in secreted form of body waste.

Eccrine is basically present in forehead region, palms of the hands and soles of the feet etc. The sweat produced by Eccrine is composed of 90% water with less percentage of sodium. Because of having higher percentage of water sweating through Eccrine does not produce ill smelling effect. While Apocrine is found in armpits and root of hair follicle produces sweat with high salt concentration. When sweat produces by Apocrine is broken down by bacteria it causes bad smelling sensation which can be felt easily particularly during high sweat production.

Sweating is one of the best ways to replenish body wastes and heat in the form of watery mixture of salts. If this excretory system is disturbed or sweat production lowered down due to any reason then it can lead to complicated physical problems including heat stoke and faints which are common problems during severe hot weather condition. If people want to keep their natural sweating process normal to avoid physical complication and to get rid of body extra heat then they must maintain their water intake level at two gallons per day. Otherwise inadequate perspiration could lead to undesirable physiological conditions and mental disturbance. So these are the factors and whole physiological process that explains why do we sweat.
