Ep 62: Burnout Explained: Brain, Body, and Stress Response (Featuring Jessica Maguire)
We've talked about burnout a lot. But this week, we brought in someone who can explain why it's happening in your body — at a biological level.
International bestselling author and physiotherapist Jessica Maguire joins the Mandys to break down the nervous system science behind burnout, and honestly? Everything finally makes sense.
This episode covers:
What the vagus nerve actually is and why it controls so much more than you think
Why burnout isn't a willpower problem — it's a physiology problem
The "hot water" analogy that perfectly explains how we end up completely depleted
Why the freeze response gets unfairly judged (and why it's not weakness)
The physical symptoms of burnout you're probably not connecting to your job — gut issues, brain fog, immune problems, loss of libido, and more
How to start regulating your nervous system if you're already deep in it
Why play — yes, actual play — is one of the most powerful recovery tools
The role of shame, perfectionism, and overachieving in keeping you stuck
Jessica has trained over 25,000 people through her nervous system programs and her book The Nervous System Reset has been published in 9+ languages. This one is packed.

Jessica Maguire explains that the vagus nerve plays a major role in regulating the nervous system and stress response, impacting everything from digestion and immune function to emotional regulation and recovery from burnout.
2. Why does Jessica say burnout is a physiology problem, not a willpower problem?
The episode explains that chronic stress changes how the nervous system functions, meaning burnout is not simply about motivation or mindset—it’s a biological state of depletion and dysregulation.

Jessica and the Mandys connect burnout to symptoms like gut issues, brain fog, chronic fatigue, immune problems, low libido, and emotional numbness that many people do not immediately associate with stress.
