Really not sure if this is satire.
I’ve tried this method at a spa, it’s pretty effective. I’ve looked into getting a Japanese style soaking tub for my spare bathroom so I could also fit a sauna and just do it at home, but it’s still not enough space. I would user a lower voltage taser probably if I was doing it myself.
Would not recommend this unless you’ve studied the Wim Hof method and have medical supervision.
