Hof is an extreme athlete noted for his ability to withstand low temperatures. [2] He attributes his feats to his Wim Hof Method (WHM). [3] Hof's first relevant experiences with the cold goes back to when he was 17: he felt a sudden urge to jump into the freezing cold water of the Beatrixpark canal. [4]
Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).
A vacuum is the best insulator, but its use in clothing is impractical. Dry air is a practical insulator. Extreme cold weather clothing uses still dry air to insulate the body, [2] layers of loose air trapping material are most effective. The inner layers should conduct moisture away from the body.

Secondary cold agglutinin syndrome occurs when autoantibodies bind to red blood cells, rendering them subject to attack by the complement system. [17] It is a result of an underlying condition potentially associated with either monoclonal cold-reacting autoantibodies or polyclonal cold-reacting autoantibodies [16] predominantly caused by infection or lymphoproliferative disorders.
