When your sore, is it better to take hot showers or cold showers?

I just joined the cheerleading team and we started cheerleadin boot camp and the workouts are EXTREME! my back is soar, my butt, my abs, and my thighs. I heard hot showers help relax the muscles but i also heard that cold showers are better, thats why athletes take ice baths. But im not sure which is true. so since i was really soar and need to relaz my muscles, is it better to take a hot or a cold shower?
