This video is made 18 January in Ukraine, in Kherson. The temperature is -15 C. But those people are blessed  and they do the same every year in this special  day.

A celebration of baptism happens on January 19. It is a celebration of the baptism of Christ. 

In the morning before the service, volunteers cut an opening in the ice, usually in the shape of a cross, for people to sink into. This cross cut in the ice has a special name “Iordan” (Jordan) because Christ was baptised in the Jordan River. The water is blessed by a priest, and the participants of the ceremony take a swim in the icy cold water. Amazingly, people hardly ever get sick after such a chilling experience. It is believed that you can heal many illnesses by swimming in the river on this particularly holy day.
