i am regularly taking a bath everyday ,,but use tap water only.. when you mean by a cold bath does it mean to put an ice on it or something?

well i do agree with that.. after brisk walking in the morning i usually use warm water in taking a bath or something..since i do believe that cold water will have bad effect on our body..(especially after a strenuous exercise or jogging)..

I bet that any sudden change in temperature will boost body systems, temporarily, as the body goes into over drive trying to adjust.
