Question:
How should people intake drinking water? Should the water be several degrees below room temperture? Or should it be cold?



Replies:
I don't think there is any optimal temperature for drinking water. Obviously, it shouldn't be so hot that it burns your mouth, or so cold that it is uncomfortable. But people routinely drink ice water at essentially 0 C. In the heat of summer people usually prefer cooler water but this is more a perception than increased metabolic cooling since the heat capacity of water is 1 cal / gm C. This is one thermal, not food calorie. One food calorie is equal to 1000 thermal calories so you would have to drink one liter (almost a quart) to provide your body with a single food calorie.

Debbie,

I'm not aware of any strong benifits to drinking water at any given temperature. While many people prefer cold water to help cool them down, or just because it feels better, many public speakers will drink thier water at or slightly above room temperature while speaking. The reason for the warm water is that it's said to help keep the vocal cords relaxed, and prevents loss of voice.
