In a new clip from Running Wild With Bear Grylls, Nick Jonas strips down to hop in an ice-cold lake, risking cardiac arrest and losing circulation in his hands and feet. In the clip, Grylls takes the pop singer across the lake in their journey through the Sierra Nevada Mountains. Jonas repeatedly reminds himself “we can do this, we got this” as the artist slowly loses all feeling in his hands and feet.
After two minutes and 50 seconds in ice-cold water, Jonas’ feet had trouble gaining back circulation, partially due to the singer’s diabetes which commonly causes low circulation to the extremities. Grylls lends a hand (or an armpit) to warm the star’s feet.
“My toes are freezing,” Jonas says in the clip. “It’s crazy what happens to your body, the instincts that kick in. You just have to go, push yourself.”
Jonas took on the journey with Grylls — which also included cooking bird guts — on Monday night’s part-one premiere. Running Wild With Bear Grylls is set for its second premiere Tuesday night (Aug. 2) with Julianne Hough.
