Ice Cold Water

Recently I have become a drinker of warm water. Sounds strange, but just may be practicable. As I grew up, about sixty years ago, most people drank water out of the tap. There were drinking fountains in most public buildings. A lot of them bubbled straight up. In my first school there was a fountain like that. The water came straight up through a ball looking device. One would turn the water own, get a drink and the extra water would fall down on that ball, which would possibly contaminate the water for the person drinking later. The next drinking fountains would shoot the water out from the side. The extra water would fall down into the drain. Later, most of the fountains in public places and office were refrigerated that produced cold ice water. In the 70’s, fountain drinks with ice were available in gas stations and convenient stores. Ice was also provided to make a cold drink of water. I didn’t eat at restaurants much. But now everywhere water is ice cold or served with ice.

I like to shave using hot water, and brush my teeth using cold water. Now I am changing. I still use hot water to shave, but I am beginning to use warm water when I brush my teeth. What’s the Point? You may ask. I have observed that I can drink more water if it is warm and than if it were ice cold. It takes longer to drink ice cold water. I could hardly ever drink a full glass of ice cold water. The point is if you drink warm water you will drink more water on a given day than if it were ice cold. I had heard that those that do not drink much water or more likely to develop kidney stones. I googled kidney stones and one piece of information that I got was there are more cases of kidney stones in the last thirty year than there were before that. I copied the following from the internet:

“A simple and most important lifestyle change to prevent stones is to drink more liquids—water is best. Someone who tends to form stones should try to drink enough liquids throughout the day to produce at least 2 quarts of urine in every 24-hour period.”

Could one the causes of more cases of kidney stones be the introduction of ice cold water?
