This is StRest! In this conversation, Kerstin sits down with stress physiologist, author, and keynote speaker Dr. Rebecca Heiss—a leading expert on how to reframe stress as energy for growth. Together, they dive into the science of hormones, mindset, and resilience, showing how stress isn’t something to eliminate, but a powerful tool to harness.

Dr. Rebecca reveals her Fearless Stress Formula—a three-step process to stop resisting stress, get curious, and redirect that energy into purpose and service. From cortisol myths to the science of oxytocin, from movement and sleep to post-traumatic growth, she explains how stress can actually extend your life when you change the way you think about it.

This episode will challenge everything you’ve believed about “good stress” and “bad stress.” You’ll leave with practical steps—invite the tiger in for tea, get curious instead of calming down, and turn stress into a trajectory of service and meaning.
