Benefits of drinking water.

Water not only prevents us from becoming dehydrated but is also a vital chemical that our body needs to lubricate the joints, accounts for 22% of bones, assists the body to remove wastes, makes up 83% of blood, regulates body temperature, composes 75% of the brain, helps to carry nutrients and oxygen to the cells, moistens oxygen for breathing, helps to convert food into energy, protects and cushions vital organs, makes up 75% of muscles. Without water cells cannot grow, reproduce or survive.  The body can survive for weeks without food but only a few days without water.

A good rule of thumb is to drink a litre of water per very 25KG of your weight.  I would suggest you start drinking early in the morning so that you are not up all night peeing!
