On November 7, Lewis Pugh completed a one-kilometer swim in the freezing
waters of King Edward Cove, off South Georgia in Antarctica. He was wearing only
his swimming glasses, cap and speedos!
Pugh is an advocate for our oceans and seas, working to protect these
ecosystem with their large diversity of marine life. When asked why he doesn蒺t wear
a wetsuit, Lewis says,
“
I ask world leaders to do everything they can to protect our
oceans. Sometimes the steps they need to take are difficult and unpopular. If I蒺m
asking them to be courageous, I must also be. Swimming in a wetsuit would not
send the right message.
”
It took Pugh about 19 minutes to complete the one-kilometer swim in
Antarctica where the water averaged about 1.6 degrees Celsius. He says that his
body can only tolerate about 20 minutes in the freezing waters before it starts
shutting down. As he swims, his body temperature steadily drops, which in turn
causes his muscle control to drop, slowing him down. When he is done with his
swim, his support team rushes him to a hot shower and it takes almost an hour for
his body temperature to return to normal.
Doctors and Pugh caution that one must receive months of training to swim in
such cold waters. Even expert swimmers who are unused to freezing water can
drown within minutes because of the physical shock experienced by the body. Pugh
says he trained for six months before this swim.
This is not the first time that Lewis has swum in dangerous conditions. In 2007,
