Which is better after a hard workout for your muscles --- cold or warm shower ?

First warm then cold: There is no firm consensus about this, but i believe the best course is to start with a moderately warm (but not hot shower) to relax and help wash away your sweat, followed by a cold shower which improves circulation and reduces inflammation. See http://health.Howstuffworks.Com/wellness/men/hygiene/should-man-take-cold-shower-after-workout.Htm for a good discussion.
