I consistently take cold showers, and I actually really enjoy it. Has nothing to do with being tough. I just happen to feel a lot more awake post-shower, it's a lot more satisfying to dry off after (and when you get out of the shower, you aren't as cold), my skin feels better and Im quite possibly in a better mood. Also, if I have had a few drinks the night before, a cold shower is far superior than a hot shower.
