In this concise commentary, Gary Brecka explains how immersing the body in cold water triggers the release of cold shock proteins from the liver into the bloodstream. These proteins act as antioxidants, reducing free‑radical oxidation, and they accelerate protein synthesis, supporting muscle repair. The cold exposure also causes a surge of dopamine and norepinephrine, which heighten alertness, focus, and concentration. Brecka emphasizes that the practice is cost‑free and offers a practical DIY method: freeze water in Tupperware blocks, add them to a bathtub, and create a three‑day cold plunge without needing a dedicated cold‑plunge system.

If you want to have some fun, just Google cold shock proteins. These are fascinating proteins that are in your liver. When you submerge yourself in cold water, they get dumped into your bloodstream. They scour the body of free radical oxidation. They improve the rate of protein synthesis, which is muscle repair. And then you get a dump of dopamine and norepinephrine, which make you more alert, more focused, and more able to concentrate. And it's free. If you don't have a cold plunge but you have a tub, take a Tupperware container and freeze blocks of water in your freezer and unpack it and dump it in your tub. You'll have a 3-day cold plunge for free.
