to drink or swim in it? if you are talking about drinking cold water then i have to tell you that ice cold water is my favorite drink. the colder the better. drinking cold water is not bad for you. i am not a big fan of swimming in cold water but some people love it. as long as you are not immersed to the point of getting hypothermia you may find it exhilarating. i find it unbearable. so swimming in cold water isn't bad if you can stand it.
