I’m (almost literally) just dipping my toes into cold water plunging. At my mom’s house in California the pool water was 56F. For those who don’t know, that’s DAMNED COLD. I submerged myself completely and worked my way up from 10s, 20s, 30s, 45s, 1m, to 2 minutes. It’s exhilarating. I look forward to some outdoor winter plunges in the Boston area.
