Do not drink before winter swimming:
Some people think that drinking can make the whole body hot, so before or after the winter swimming, they often warm up with wine to get rid of the cold. In fact, after drinking alcohol, on the one hand, the blood vessels expand and the blood circulation accelerates, which will make the whole body hot and warm; on the other hand, the body temperature loss also accelerates accordingly. Therefore, it is not suitable to drink before winter outing.
