Water is vital for man bodily functions and an adequate daily intake is essential for good health. How much you need to drink varies a lot between individuals. The Minimum requirement is usually about 1.5 litres but if you are active and the weather is hot you will need much more to replace the extra lost in sweat. Not all water has to come from drinks - food, particularly those with a high water content such as some fruits and vegetables make a significant contribution. A small way to check your hydration levels is to check your urine - this will show if your are drinking enough water - it should be a pale straw colour. If you feel thirsty then this is a sign that you may already be dehydrated and should drink at least 250mls straight away.
