The use of very cold temperatures for medical treatment to help reduce pain and inflammation or to promote healing.
Athletes often use cryotherapy to recover faster after intense workouts.
Cryotherapy is formed from "cryo-" (from Greek "kryos", meaning cold) and "therapy" (from Greek "therapeia", meaning treatment). The word refers to treatment using cold temperatures.
Think of 'cold' ('cryo-') being used for 'treatment' ('therapy') — that's why cryotherapy involves treating conditions with cold.
