Dangerously cold temperatures across the continental United States didn't stop the bravest from participating in annual Polar Bear Plunge events, which often raise money for charity.
Milwaukee's loosely-organized annual Polar Bear Plunge into Lake Michigan continued as plan despite temperatures hovering around -3 degrees Fahrenheit, according to WISN 12. Unfazed participants at noon began diving into the 33-degree water.
Because of the cold, event organizers cautioned participants of the extreme dangers associated in nearly freezing water. They posted on the website,"Due to the extreme cold conditions expected on January 1st, 2018 it is recommended by medical professionals that you do not participate in this event. There are several other Polar Plunges in 2018 when the weather conditions may be more favorable. If you choose to participate, you are doing so at your own risk."
Hundreds of miles away, some Polar Bear Plunges in New York and New Jersey also proceeded as scheduled. According to NJ.com, two Jersey Shore towns canceled their events, but the show went on in Asbury Park and Atlantic City.
One man who's been taking part in Polar Bear Plunge events since 2011 made an important observation while justifying his seemingly unfathomable act of voluntarily diving into sub-freezing water.
"It's actually colder outside the water than inside the water," said 47-year-old Matt Andras said.
According to WKYC, the Edgewater Park Polar Bear Plunge, on the other hand, was canceled in Ohio because officials had difficulty cutting a hole into the ice.
