Temperature and duration determine how effective an ice bath will feel. The higher the bath temperature, the longer you’ll need to soak. The optimum temperature and time is 10-15 degrees C (50 – 59 degrees F) for 5-10 minutes. It is also normal to find professional training facilities that use temperatures between 6-10 degrees C (42-50 degrees F) with recommended therapy treatments of 3 to 6 minutes.
