In terms of hydration, which is better for you, warm, or chilled water?
I don't think that the temp of the water matters as much for hydration, but ice water is better for helping boost your metabolism.
water is absorbed in the large intestine .
by that time , it's @ body temp. , soooooooo..
oh , and R , dear , tell us - which component in water does this imaginary boosting ? Hmmmm? Caffeine , maybe ?
too many snapple commercials , Love.
warm water is good but when it comes to tired body chilled water can relax it.
Cool water – not carbonated beverages or sports drinks – is the best fluid for keeping hydrated when it’s warm outside. Cool water is absorbed much more quickly than warm fluids and may help to cool off your overheated body. If you’re going to be away from home or outdoors, make sure you keep a bottle of water close by.
Cool water is best...Too cold can shock a "hot" system. Drinking freezing cold water too fast can cause what is called a vaso_vegal reaction where your body shuts itself down because it thinks you are in trouble.aka "brain freeze"..The vegas nerve runs parallel and behind your esophagus.. on the other hand.Too hot can raise your body temp. but not by much.
