He said Australians based at all three stations, Davis, Casey and Mawson, take part in the traditional "Bliz Run", which obliges the loser of any bet or dare to strip off and run a lap of the accommodation block.
"It's only about 100m, but even 10m would seem like a long run in the conditions," Dr Cormick said.
New Zealanders at their summer station go skinny dipping in Lake Vanda, with a plunge in the chilly water earning membership of the Royal Lake Vanda Swim Club.
The group is rumoured to include former NZ Prime Minister Helen Clark, who gained membership before she was elected.
Americans at the Amundsen-Scott base can regularly be seen emerging from the sauna to run a naked lap of the South Pole.
The deed earns membership of the 300 Club, but only if it's done when temperatures have plunged to below -100F.
"The idea is to run from the 200F sauna, outside, so they go through 300 degrees (F) in seconds," Dr Cormick said.
