, a certified holistic health practitioner, and the author of "the biology of beating stress," jeanne ricks. thank you so much for being with us today. >> thank you. i want you to just take a deep breath right now. just one... [ breathes deeply ] hold it. [ exhales ] now, just in doing that one thing... >> mm-hmm. >> ...you've signaled to your unconscious mind that there is no tiger chasing you, that there's absolutely no reason to be upset or anxious because we do that shallow our day. too many of us just shallow-breathe, and subliminally -- think about it. when you're shallow breathing, possibly potentially some danger. so when you just do that deep breath, just two or three of them, it settles down that cortisol response. >> so you're telling me it's that easy? >> it is that easy. you need to do it multiple times throughout the day, but that's just one part of stress reduction, but it's an important part because, again, subliminally, your mind is racing. all day long we're doing that little shallow breathing. when was the last time you took a deep breath? [ chuckles ] >> i don't know. [
