We are often told that we need to make sure we keep having a drink even when we are not always thirsty. Water is vital to keep us healthy and here is why:

How much water is in our bodies?

On average, our bodies are made up of about 40 litres of water. Major body parts, such as your blood, muscles and bones, are mainly water so it therefore plays a key role in helping us stay alive.

Why should we drink water?

If we don't drink enough water our bodies can become dehydrated and this can cause us to become tired and feel unwell. If we feel thirsty, have dark coloured urine or have dry lips this may mean we need to drink some more water. This often happens when our bodies are losing more water than we are putting into it. We lose water all the time through sweat, faeces, urine and when we breathe out (check on a cold day for the water turning into vapour as you breathe out). Therefore it is important to make sure we are putting enough water into our bodies to keep it hydrated.

How much water should we drink?

It is recommended that we should all drink at least 2 litres of water a day in addition to any other drinks we have e.g. fizzy drinks, coffee or tea.
