An important step of the Wim Hof Method is warming up your body after being exposed to extremely cold temperatures. A warm up gradually revs up your cardiovascular system by raising your body temperature and increasing blood flow to your muscles.
Wim Hof is famous for breaking numerous records relating to cold exposure giving him the nickname "The Iceman". One of his many Guinness Books of Records is standing in a container while covered with ice cubes for more than 112 minutes.
