Not saying you guys are wrong. Although I was told never take cold water during a fight, during exercise I always drink cold water and it's never made me tired or took longer to consume?
COPY & PASTE
Is drinking cold water during or after exercise good for you or bad for you? Does the temperature of the water matter at all?
A. Believe it or not, cold water is absorbed faster by your body than water at room temperature or at body temperature. The American College of Sports Medicine recommends that water and other drinks be chilled when used for exercise.
Cold Water and Cold Drinks Rehydrate Faster
Research has shown that cold water passes through the stomach faster and is therefore sent to the intestines for absorbtion faster. During and after exercise, you want to replace fluids lost due to sweat rapidly, so cold water and cold sports drinks are preferred.
Look at me Mom!, I'm on top of the food chain!
