This episode explains what stress is, and how it recruits our brain and body to react in specific ways. I describe the three main types of stress, and how two of them actually enhance the function of our immune system making us less vulnerable to infections. I review tools that allow us to control our stress in real-time, as well as tools to prevent long-term stress, burnout and stress-induced illness and anxiety. As always, we cover behavioral tools and supplements that can assist or hinder stress control. Read the full show notes for this episode at hubermanlab.com.
