Winter swimming is a method that renews among Poles, for a healthy life in a strong and beautiful body. The benefits of entering the icy water are very many and they are not just physical. During such baths our psyche also changes and the breaking of fear and internal barriers opens new ways of development. Collective swimming is safer, that's why "wales" merge into groups and creating a family atmosphere, organize occasional events, compete in sports competitions and go on trips. In Warsaw, there are several "walrus" clubs that meet regularly for jointly baths.
