The directive to "drink lots of clean, safe water" is a unique and very important one for people especially Africans living in the hot dry part of the World. Remember, this is the substance known as universal solvent the unavoidable nutrient, the neglected nutrient and the most important nutrient. Water is the most persuasive compound in the human body. It is well known that we can stay without solid food for some days but we hardly live without water.

In the chemistry world, water is seen as a compound that is composed of two elementary entities namely Oxygen and Hydrogen. These elements are combined by a chemical bond called polar covalent bond in the ratio of 1:2 respectively and this has made water a solvent for all polar substance thus the name "UNIVERSAL SOLVENT".

Most biochemical reaction in our system needs water and the most interesting part is that water is the most active participant in these reactions. It is involved in dilution, dissolution, transportation and above all assist in absorption and distribution of substance (nutrient, antibodies, genes, hormones, waste) round the body. The most easily appreciated biochemical roles of water in human body are: to provide a medium for transportation of  blood component, to dissolve and pass nutrient from blood to cells for growth and body maintenance, to provide a medium for intracellular reactions to take place and to transfer metabolic products to the blood for redistribution or elimination via urine.

Water, however, also performs the role of heat distribution (thermo regulation) in the human body. It is the major component of the thermoregulatory system of the body. Water absorbs heat generated and dissipates it over the fluid compartment of the body, minimizing the risk of localized damage to enzymes or structural proteins by heat. Once the heat of chemical reaction has been transferred by water to the body fluid, it is routed to the surface of the skin where it is dissipated by conduction radiation, or evaporation.

In fact, water is essential to life. No other substance is as widely involved in as many diverse function of the human body as water. The function and importance of water can never be over emphasized. Take lots of clean, safe water at lest two (2) litres every day so that you can grow in health of mind and body.
