Some of our favorite highlights from this episode include:
  • The gold standard for anxiety in teenagers it's been shown to improve heart rate variability. There is a series of self-help books from my friend who's an amazing child psychologist, Don Hener.
  • That's coherence, right? That's the state of optimal heart rate variability. Belly breathing is really important to learn how to do well because, by the time we're an adult, we breathe through our shoulders and not through our diaphragm.
  •  So when we optimize vagus nerve functioning, the signs of vagus nerve function, point to optimal health. And one of the ways we can measure vagus nerve functioning is through something called heart rate variability, which many of you guys may be familiar with.
  • There are particular probiotic strains that have been shown specifically to improve optimal neurotransmitter levels and help with depression, and anxiety manage stress, and reduce cortisol. So we definitely wanna get in our psychobiotic if we're having these concerns while fixing the rest of the gut. And of course, omega-three and quercetin is a really great healing nutrient for your gut too.
