Water is the main component of human body and a critical one, comprising 60% body weight for the average male and slightly less than this for the average female. Internally, the body's cells depend on water to maintain their function and volume, water is also vital for optimal plasma function and hence electrolyte balance. The body's organs also rely on optimal hydration for functioning at their metabolic peak. Given the critical role of water in the body and as the body is unable to store water, it's vital that any water lost (for example through perspiration) is replaced on an ongoing basis.
Water can be added to the body in one of two ways, the first and most obvious is by drinking water, however, food is also a conduit for water intake particularly fruits and vegetables. The quickest, most effective and cheapest way to hydrate, however, is by drinking water. The amount of water that is needed is dependent on a number of external factors, among these, level of physical activity, the state of health and ambient temperature.

Dehydration is a condition that occurs when the body does not have sufficient water to perform normal physiological functions. The most significant impact of mild dehydration in the short term is mood impairment. In the longer term, there can be an negative impact on cognitive function. Both of these factors can affect performance in the workplace. Therefore, during the course of the busy working day, it is important to hydrate regularly. Provision of filtered drinking water in the workplace is an effective way of increasing individual's water intake.
Consumption of adequate water results in increased energy and can promote weight loss, people that drink more water usually eat less because they are fuller. Drinking sufficient water helps to maintain body fluid balance and is also associated with a healthier complexion.
