Hydration and its benefits (Cold or room Temperature?)

Hi

As part of the research I am undertaking for my Health and Fitness portfolio I have had a number of views and suggestions on keeping hydrated and how water can help alleviate a number of conditions.

It is quite apparent that a regular hydration regime is vital to maintain good health, there is one question that I would like to put out there about cold or room temperature water intake

I have been told that drink cold or chilled water is useful as the body's metabolism kicks in the warm the water up and this helps burn calories, however another view is that using room temperature water is better?

Over to you informative and support group members for your views.......

Thanks

Paul
