Look it up, but it's possible that cold showers are not good post-exercise due to them hindering blood flow and preventing removal of waste materials from muscles.

Due to the anti-inflammatory effect of low temperature, cold showers soon after resistance exercise may be attenuating muscle hypertrophy response.

Of course, as with most factors other than sleep and nutrition, the magnitude of that effect will likely be unnoticeable to all but elite athletes striving for that 0.5% edge over the competition.

Cold showers will not leave you as clean. There's a reason you wash your dishes,hands, and underwear on hot water cycles.
