I have read a couple of things that say Drinking cold water constricts your organs slowing digestion. I have always herd that cold water is better for you especially during the summer months. I know there was a bogus article floating around about dogs getting sick from drinking cold water and this seems to be along the same lines. Any inputs on this?
Oh and the actual answer for drinking cold water, drinking ice water in large quantities has been shown to put more stress on the body’s thermoregulator system and may be a bad idea to do frequently. But no short or long term affects were found. As most people do not consume more than an ounce or two in a swallow and usually not more than 3 to 5 ounces every 15 to 20 minutes (and most often with food), I would not worry too much about the water being cold.
