On cue to welcome me to my 50s, I had shingles just a few months before my 50th birthday. Meds didn't stop the shooting excruciating what the fuck I'm gonna die pains. The only thing that helped was cold plunging. It happened during a freeze here in Portland and I actually had to break ice off my trough to get in. Total reset of the nervous system. I've had a hot tub and cold plunge in my backyard for over four years and it's a staple for my health. I've also taken the trough to the Deschutes River to set it up as a hot tub and then cold plunge in the river. It's no joke good for the body and soul.!
