Alexandre Fuzeau (AKA the Ice Doctor) explains what happens to your body on long cold swims

Few sports test the body and mind so rigorously as winter swimming. Whether we’re talking about the extreme “Ice Mile” of the International Ice Swimming Association or the more accessible 450m endurance swim of the International Winter Swimming Association, swimming in cold water represents one of the purest challenges for the human body: almost naked and without help or special equipment, you depend totally on your physical and mental capabilities to succeed.

But what exactly does your mind and body go through to complete an endurance cold water challenge?

According to FINA, swimming’s international governing body, the minimum water temperature for events under their rules is 16 degrees Celsius. The drop from 16 to close to zero might not sound much but, from a swimming perspective, it is extremely difficult to handle. In addition to the sudden immersion in near-freezing water, the body must cope with rapid cooling while retaining optimal muscle and brain functions, and then has to re-warm once you leave the water.

Winter and ice swimming (the latter usually defined as swimming in water of less than 5 degrees but often involving pools cut out of frozen lakes or rivers) are becoming increasingly popular. For example, in March 2016, 1275 swimmers from 36 countries gathered in Tyumen, Siberia, for the tenth bi-annual Winter Swimming World Championships. The water temperature was minus 0.6 degrees and had to be constantly agitated to prevent it from freezing.
