Another factor that you may not realize is that cold showers reduce, if not stop, the vaporization of chlorinated water that is in most municipal water systems.
I have for years now taken luke warm showers at the start and after rinsing off soap I end the shower with a cold rinse. In the summer up here in the last frontier I bath in the creek behind my cabin with just the sand gravel from the bank while using baking soda for washing my hair. I have noticed that I have no B O even without any soaps or deodorants.
