A man in 'ushanka' (Russian fur cap with ear flaps) standing barefoot in the middle of Moscow snowdrift. Slipper nearby. What could it be?
Conditioning to the cold was very popular in Soviet Union. Cold water plunges in a common backyard were often. A man, wearing swimming trunks and slippers with a tin-pan full of ice-cold water in the middle of winter was not a non-sense. Naked toddlers, jumping into ice-hole together with their young parents seemed normal. All of those facts were parts of a big conditioning to the cold movement.
Pediatrics believed that kids, grown with some short therapeutic periods of an extremely cold temperatures of water and air become stronger. They even used to organize winter plunges for 4-5 year olds in kindergaden. Nowadays Russians are less obsessed with those theories. Still we jump to snowdrifts (as our Finnish neighbors) and ice-holes after the sauna and gave a second life to a traditional Epiphany ice-hole swimming.
