The human body functions the best at a stable temperature of around 97.7-98.6°F Thermoregulation is the maintenance of internal core body temperature by balancing heat generation with heat loss.  When I was participating in XTRI ICON in Livigno, Italy on September 1st, I experienced symptoms of hypothermia after the swim portion of the race. The air temperature was 32 degrees F and the water temperature was 52 degrees F.
