This episode is brought to you by Rupa Health and Athletic Greens.  Hormetic stressors are good stressors. These are actions that, in the right dose, have the power to lower inflammation, boost tissue repair and metabolism, and support our mitochondria. It’s like the saying goes: what doesn’t kill you makes you stronger. Things like exercise and strength training, hot and cold therapies, light therapy, ozone, and others are all mild stressors that jump-start your body into repair and rejuvenation. In today’s episode of my series I’m calling Health Bites, I dive into how adversity and little stresses to your system (i.e., hormesis) activate longevity pathways. What I’ve discovered has blown my mind and changed the way I approach my own health and the health of my patients. I’ve compiled it all into a new book called Young Forever, which comes out on February 21, 2023. Learn more and preorder the book at youngforeverbook.com.
