- One in five women drinks less than the recommended daily intake of water
- Every system and function in our body depends on water.
- Especially because the liquid flushes toxins from vital organs

You might think I'd have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water.
Usually I start my day with a cup of tea, then I might have a glass of water with my lunch and one with dinner - that's about a litre of liquid in 24 hours. It feels like plenty, but apparently it's not nearly enough.
After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three
litres of liquid a day for my body to function at its best.
After four weeks: Sarah looks like a different woman
Then, when I read a recent survey suggesting that at least one in five women in the UK consumes less than the recommended daily intake of water, I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month?
The photograph of me taken the day I started this trial demonstrates perfectly - and rather frighteningly - what a lack of hydration does to a face.
I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which make me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any lustre. It looks dead.
