From what I understand (Matthew Walker - Why we Sleep), you will have a better nights sleep if you take a cold shower before bed. According to the information I read, you want to bring your body temperature down for a more restful sleep.
As a bonus, cold showers likely bring on Hormesis, which in turn can also be beneficial for ones health.

I've heard the same thing, except the suggestion was for a hot shower, because supposedly the heat makes your body work less to stay warm and the end result is actually lower core temperature.
