Water, Hot vs. Cold

I've heard a lot of debate over the year looking at cold water vs. hot/warm water. And it became discussion in the office earlier this week as to which is "better". I don't mind drinking warm water (unless it's summer in Texas and 100+ degrees) so I started to look a little further into the subject of which really is "better" for you, or does it make a difference at all? One site that I found Healthy Drinking Water Blog mentioned a lot of benefits of drinking hot water: Purification

Some believe that drinking hot water is much like going to a sauna. It purifies the body. How?

* As you are drinking hot water, your body temperature rises slightly.

* To maintain its average 98.6 degrees Fahrenheit, your body begins to perspire. Perspiration is its method of cooling itself.

* Perspiration induced by drinking hot water flushes toxins from your body, helping to purify your bloodstream.

They suggested that in order to get the "purifying" effects to drink hot water once or twice a week.

Nasal Cavity Clearance

*The warm water actually makes you feel less congested! I found this to be true as I was drinking lots and lots of tea a few weeks ago when I was sick! Who knew?!

Now for the Cold Water--there isn't a whole lot that backs up the "idea" that cold water burns more calories...but there is the notion that the body has to burn around 7 calories to bring the body temperature back up to 98.6.

I think that the purification benefits sound better to me than the couple of calories, what are your thoughts on the hot vs. cold debate?
