There's no better way to welcome the new year than going into shock in ice-cold water ... for a good cause, of course!

Tired of spending your New Year's Days hungover? While all those other suckers are nursing a headache and stomachache of epic proportions, you could be doing something amazing for the American Cancer Society (ACS) ... and all it takes is immersing yourself head to toe in freezing ... I mean, invigorating waters (it's probably a good way to cure a hangover, too)!

It's almost that time of year again for the annual Boulder Polar Plunge when hundreds of brave souls flock to the shores of the Boulder Reservoir to raise funds for cancer research and more.

What: American Cancer Society Boulder Polar Plunge
Where: Boulder Reservoir
When: Tuesday, January 1, 2019 | 11 a.m. registration; 12 p.m. plunge

"Your participation allows the American Cancer Society to fulfill their mission to save lives, celebrate lives, and lead the fight for a world without cancer. Your support is making a difference!" said the organization. The 2018 event saw almost 600 in attendance and raised nearly $28,000 for the ACS.

The first event was held in 1982, and it drew both flocks of participants and spectators who headed down to Boulder Reservoir to ring in the New Year.

This year, you could test your mettle and be among the many that take the plunge! And because this is Colorado, once those of you who are over 21 have thoroughly shocked your system back to the Stone Age, you'll enjoy a post-plunge Avery brew and the warming tent. Teams and individuals can participate. The teams who have raised the most funds will be allowed to go first, with individuals in between each team. 

And, in case you're afraid that every part of your body will completely stop functioning, there will also be several divers on hand for your safety.

If you want to be freezin' for a reason this New Year's Day, visit the event page and register. If you'd rather your appendages (I'll let you decide which ones I'm talking about) not freeze and fall off, you can help out by making a donation to ACS.
