VIDEO: Each day first responders face life and death danger. With each 911 call, the heart beats faster, anxiety skyrockets, and the mind can lose focus. But there could be a way to train ourselves to remain calm even in the most stressful situations.
Wim Hof, better known as "The Iceman," has created a method to reduce stress and strengthen the immune system to help train the mind to survive. It involves jumping into a tub of ice water at 30 degrees Fahrenheit.
"If we look at the ice and we say 'yea you know ... this is going to be uncomfortable.' Yeah, it's going to be challenging. But I have control," says Ben Dubin, a captain with the Tempe fire department. "This environment does not dictate how much control I have in this environment."
