What is the maximum duration recommended for cryotherapy application?

The recommended maximum duration for cryotherapy application is typically around 15 to 20 minutes. This time frame is based on the physiological response of the body to cold exposure. Cryotherapy is often employed to reduce swelling, inflammation, and pain in acute injuries. Prolonged exposure beyond the recommended time can increase the risk of tissue damage and frostbite, as well as induce a paradoxical increase in blood flow to the area after the cold stimulus is removed.

Therefore, while 45 minutes could seem like a reasonable duration for treating an injury, it is generally deemed excessive, as it could lead to negative effects rather than beneficial ones. The 15-minute guideline serves to maximize therapeutic benefits while minimizing risks associated with cold exposure.
