Take a 'polar bear' plunge

At this time of year, usually from mid-December to early January, people dive into lakes, rivers or oceans. Freezing water. Icy water. They do this deliberately. Why? Mostly for fun. Sometimes for charity. Sometimes for physical health and vigor (that's especially true among Europeans). And a few do this naked.

The first club in the United States was founded in 1903. The Coney Island Polar Bear Club continues to this day (its main event is planned for New Year's Day). Other plunges occurred last January in places as disparate as Seattle; Boulder, Colorado; Jacksonport, Wisconsin; Indianapolis; Pittsburgh; and Brigantine, New Jersey. Even in Orlando and Sanibel in Florida. Whoa! What's that again? Florida is an ice-free zone. But everyone wants to get into the act. Orlando had its event in an indoor ice arena. Sanibel's plunge was December 12 in the "icy" Gulf of Mexico. 

It is widely believed that cold-water swimming contributes to a better well-being: less stress, greater vigor, better mood and better memory. One study discounts the common notion that winter swimmers catch colds more; the researchers actually found that frigid water produces oxidative stress, which improves antioxidant protection against disease.

But Polar Bear Plunges aren't for everyone (and I'm not counting those such as me who think going into icy water is crazy). Anyone thinking of trying ice swimming should be certain that they have no underlying cardiac issues or blood pressure problems. Also, watch for hypothermia from exposure. Keep outer clothing on until it's time to take the plunge. And, no alcohol. Alcohol accelerates hypothermia. Have a towel to dry yourself off immediately.

No doubt these gentlemen have taken sufficient precautions and are ready, willing and able to take the plunge. Let's watch and enjoy.
