6 Minute English / Are you drinking enough water?

Note: This is not a word-for-word transcript.

Hello. This is 6 Minute English from BBC Learning English. I'm Phil.

And I'm Beth. Nowadays, I often see people carrying water bottles with them to make sure they drink enough. How much water do you drink a day, Phil?

Oh, I don't know. Maybe about a litre?

OK. And do you know how much water you should drink a day?

I think it's probably about two litres.

Ah, well, the number many people have heard is two litres a day. Of course, everyone needs to drink some water - over half the human body is made up of it. But exactly how much water do we need to stay healthy? That's what we'll be discussing in this programme, along with some useful new vocabulary as well.

And speaking of vocabulary, remember you can download all the new words and phrases from this programme, plus worksheet exercises to help you learn them, on our website, bbclearningenglish.com.

Great! But first I have a question for you, Phil. I mentioned that over half the human body consists of water, but there's an even higher percentage of water in our blood. But how much? Is our blood:

a) around 80% water?b) around 90% water? or,c) 100% water?
