Why Take Colder Showers? (Cold Shower Benefits)

Cold showers are uncomfortable, I don’t want to be uncomfortable, why am I doing this again? That is the message coming from the resistance in my head everytime I reach to turn the knob from hot to cold. I’ve been taking some form of cold showers daily for around 3 years now and that voice has never gone away. I have had to consciously face and overcome that resistance daily.
