Why Cold Works

Backed by science. Proven by over 200 peer-reviewed studies.

Cold plunging means immersing your body in cold water usually between 5°C and 15°C for a short time. It might look intense, but what it actually does is kickstart your body’s natural systems: your brain wakes up, your blood starts moving, your metabolism shifts, and your stress response resets.

It’s simple. It’s powerful. And most importantly it’s scientifically proven.

We know it can sound extreme, we thought it was a bit wild when we first considered buying our fist tub! But the science tells us otherwise and the results speak for themselves.

Backed by over 200 peer-reviewed studies, cold exposure has gone from a fringe idea to one of the fastest growing wellness practices on the planet.

We’ve included 15 of those studies below for the skeptics but if you want links to the other 185+, just ask.
