Author's Note: How Whole Body Cryotherapy Works

I like swimming in the cold Atlantic and then taking a hot bath to warm up. Afterwards I feel great. Better than great — euphoric. It's the same reason it's fun to heat up in a sauna and then roll around in the snow. I'm not sure what the science is; maybe it has something to do with promoting circulation. Cryotherapy enthusiasts report euphoria as well, maybe for the same reason. But all things considered, I think I'll stay away from the liquid nitrogen and get my kicks from old-fashioned cold water and warm air.
