Braving the cold at the 19th annual Maryland State Police Polar Bear Plunge at SanGetty Images

If jumping into the ocean in the dead of winter wearing next to nothing sounds crazy, that's because it is.

 

Yet hundreds of people along the East Coast do justthat every year.

 

The annual tradition is called the Polar Bear Plunge, and usually these brave souls do it to raise money for charities, mark the new year or chase the thrill.

 

If you're among those daredevils who'd rather splash in some icy water than snuggle next to the fire this winter, just make sure you follow the safety precautions.

 

Experts agree you shouldn't enter the frigid water intoxicated, nor should anyone who has high blood pressure or heart disease attempt the polar plunge.
