Well, nothing scientific than I'm aware of, strictly speaking, but I love the effect.

Right after the shower, you'll get super warm, even in winter. You're system just gets going to equalise your temperature.

Also, you'll be woken up no dithering about in a stupor until your coffee kicks in, it definitely gives you a kick in the backside to get going, so even just for that, it's worth it in my opinion.

And, I never get cold. I can work outside in a t-shirt in winter (UK winter) without feeling any cold.
