The idea is that the super cold dip tricks the body into thinking it’s dying, and rushes blood to vital organs like the heart, brain, and lungs to preserve them. Then when you step out of the cold the blood rushes back to your muscles again, only now it’s saturated with extra oxygen from being in your heart and lungs.

Doesn’t sound entirely safe.
