Water is a vital component of our diets, it's essential for the growth and maintenance of our bodies, as it's involved in a number of biological processes. But most of us don't get nearly enough.
|
Why do we need water? |
 |
Water comprises 50 to 70 per cent of an adult's total body weight, and without regular top-ups, our body's survival time is limited to a matter of hours or days.
Water is lost from the body through urine and sweat, and must be replaced through our diets. Many people, though, don't consume enough and as a result may become dehydrated, causing symptoms such as headaches, tiredness and loss of concentration.
|
Chronic dehydration can contribute to a number of health problems, such as constipation and kidney stones.
Water is the major ingredient of all drinks: carbonated and still drinks are 65 per cent water, diluted squashes are 86 per cent water (after dilution) and fruit juices are 90 per cent water. But drinking plain water is still the most effective way of replacing lost fluids. |

How to achieve your daily water intake |
 |
The drinking water available from our taps is perfectly adequate to replenish our fluid loss, and undergoes many processes to bring it up to the standards set out in the Water Supply Regulations. Online, 98.8 per cent of tap water sampled passed drinking water inspectorate tests.
