Cold/heat exposure are great, cold water immersion in particular. I've observed positive effects on my physical recovery. But I have not seen a comment here warning that cold water immersion is absolutely not something you should try for the first several times alone, even in very shallow water (IE a bathtub). The risk of entering shock/going unconscious and drowning is non-trivial.
