I just got my SFQ personal learning course today and finished reading through the manual. I noticed that it was not recommended to drink cold water before or after practice.

I tend to drink a lot of water throughout the day. The water I drink is usually good and cold. Should I allow the water to reach room temperature? What is the reason for not drinking cold water. Could it be a thermodynamic reason, i.e. the cold water will use some of my qi to become warmer?
