Whole Body Cryotherapy (WBC) is the stimulating use of extremely low air temperatures (below -120 degC) in a cryotherapy chamber on the whole surface of the body for a period of 2-3 minutes in order to develop defensive reflexes and reactions which are theraputically beneficial and effective in restoring the natural balance of a human organism.

Spectacular results have been obtained in decreasing recovery rates in elite sports by the use of WBC and the treatment was used to great effect by the Welsh Rugby Union squad in their build up to the 2011 Rugby World Cup.
