What turn off the inflammation when it is no longer needed, preventing it from becoming chronic, are stress hormones like norepinephrine and adrenaline.

Cold shock has been shown to reliably release up to 300 percent more norepinephrine, and the deprivation of oxygen from breath holds reliably produces more adrenaline and norepinephrine.
