The Angels may be behind the times in some areas, but if Hector Santiago's recent Instagram post is to be believed, they are somewhat forward-thinking when it comes to sports rehab. Here he is getting some treatment and subjecting himself to temperatures in the -230 degree range:
Looks like...fun? Pain? Yeah, I don't know. I've heard about this on some recent podcasts I listen to, but have never done it myself. What happens is your body is brought down to such a low temperature that it begins sending all the super-oxygenated blood to those parts that are freezing, thus helping them rehab quicker.
