'Polar Plunging Changed My Life' On 4/13/21 at 5:32 AM EDT On the first day of March, I plunged into the freezing water of Nantucket Harbor. The high that day on the small island island thirty miles off the coast of Massachusets was 46 Farenheit, but in I went. I proceeded to plunge every day of that entire month. This may seem bizarre—why would anyone subject themselves to that?—but after 31 days and 31 plunges, I think I've found an answer. Plunging is meditation. It's healthy and exhilarating. It builds will power and discipline. And it can become a community event, if you let it.
