Tea or Water, which is the best to drink? Well according to the NHS “Drinking four to six mugs of tea a day is as good for keeping you hydrated as a litre of water,” reported the Daily Mail. It said the finding disproves “the idea that regular tea drinking can dehydrate the body because of its caffeine content”.

With all this hot weather we all know that we should keep ourselves well hydrated but how much do we really need for our health ? Well scientists now say that you should work it out by your body mass.

To do that you simply take your weight in lbs and divide it by 2.2, multiply that number by your age, divide that sum by 28.3 and your total is how many ounces of water you should drink each day.
