KENOSHA, Wis. (CBS 58) -- Teachers at a Kenosha school took the plunge into a chilly lake Friday. 

Teachers from Nash Elementary jumped into Lake Andrea Friday morning. Students raised more than $15,000 for "Jump Rope for Heart." 

The program raises awareness for heart disease and stroke by encouraging people to stay active and live a healthy lifestyle. 

One of the teachers says taking the plunge can take your breath away, almost literally. 

"All the air goes out of you and it's just hard to explain but coming out I mean my feet are cold right now, but it wasn't near as bad as it was going in. That's crazy," said David Dummer, a Physical Education teacher at Nash Elementary.
