It depends on the type of injury we are treating. In the case of an acute injury in the first hours after the trauma, it is recommended to use first the cold and then the heat and take a break of 3 to 5 minutes, and then reapply the compresses in the same order and maintain this rhythm for about 20 minutes.
In the case of chronic injuries or those in an advanced recovery phase, start by applying heat and then cold, maintaining the rhythm uninterrupted for 15 to 20 minutes before ending the session.
