a good technique that I used to use, when I lived in a country where the cold tap actually gave out cold water, was contrast showers.
Jump in the shower before the water even heats up so that you are taking a cold blast. Then when it heats up stay in the hot for a minute or so, then turn off the hot tap so you are in cold again for a minute. Alternate like this for the length of your shower ensuring that you start and finish on cold.
The cold water helps with the inflamation and the contrast with the hot gets the circulation going. These are two things that really aid with recovery.
You should be aiming for as hot and as cold as you can bear.
