Cold Plunge for Recovery

In my fantasyland facility, there is a cold and warm plunge.Science aside, I like how I feel afterwards in terms of recovery. Science considered, it makes great sense in pushing the lymphatic system and improving recovery.I am not sure the evidence is that powerful, but with a technique like this, there are so many things that can not be controlled for.It may be a case where common sense and science are not necessarily supported by the evidence.
