Hi, There's a discussion going on in my house regarding if cold water passes through you quicker then hot water,I say it does,but have been told there's no difference. Can you he please. Thanks

Some info here. Looks like warm water is better for hydration so it could mean that cold water would pass through quicker as less is absorbed efficiently?

I've only got to dip my hands in cold water and it starts passing through me!!!!

"I say it does,but have been told there's no difference."

Like lots of questions, the answer to this isn't as straightforward as you might think. In short, cold water is absorbed faster than water at room temperature, and it will rehydrate you faster.

From my link, Cold water is not as good for hydration as room temperature. The theory is that the cold water causes the blood vessels surrounding stomach to shrink, slowing absorption So who is right FE?

In most modern big city pubs you have a choice of 'normal' or 'ice cold' lagers...I usually select 'ice cold' on hot summer days and 'normal' on cold winter evenings...on days when we have 4 seasons in one day...I have a cup of coffee ;o]

frybluff - indubitably. I hope we get a long hot summer this year, though!

Who is right? I don't know, which is why I said the answer isn't straightforward.

What I do know is that The American College of Sports Medicine recommends that all drinks used during exercise be chilled. Research has shown that chilled water passes through the stomach much more quickly than drinks consumed at room temperature, and cold water rehydrates you quicker after strenuous exercise.

After a little search it seams that cold water does pass through the body quicker CLICK HERE

Knowing my luck I'll find another link that says the opposite.

  rdave13 23:47 05 May 2012

That's a good answer but leaves me puzzled. If chilled water passes through the stomach faster than room, or ambient temperature, water then the stomach surely digests, or absorbs, less of it to hydrate the body and then the kidneys and liver removes it in a purer form or water rather than urine?

Just a thought.
