No, however because of the breathing exercises you will supercharge your  body and mind. This will make it easier to go for a challenge (move mountains). In this case a cold shower/ice bath :). Another physical effect is that the pain receptors go down after the breathing, wich makes it feels better to adapt to the cold. If you are not able to shower directly after, do a mini breathing exercise before you step into the cold shower. (30 deep breaths and focus on your "challenge") Good luck See the video ‘Taking a cold shower’ in the ‘Introduction’ section of the course.
