In this episode of Proactive Wellness for Nurses, Jessica Veloza, APRN and functional medicine coach, explores one of the most overlooked drivers of burnout, metabolic dysfunction, and weight struggles in nurses: the vagus nerve.
Many nurses feel frustrated when they are doing “all the right things” for their health — eating better, trying to exercise, attempting to lose weight — yet their body still feels stuck in stress mode. Energy crashes, sugar cravings, sleep disruption, inflammation, and stubborn weight gain are incredibly common among healthcare workers.
What many nurses don’t realize is that these symptoms are often connected to nervous system dysregulation and low vagal tone.
The vagus nerve is the longest cranial nerve in the body and serves as a major communication pathway between the brain and key organs including the heart, lungs, digestive system, pancreas, and gut. It plays a central role in the parasympathetic nervous system, which controls rest, digestion, metabolic balance, inflammation regulation, and emotional resilience.
For nurses working long shifts, rotating schedules, night shift, and high-stress environments, the nervous system can become stuck in chronic fight-or-flight mode. Over time, this can impact cortisol levels, blood sugar regulation, digestion, appetite hormones, and the body’s ability to efficiently burn fat and maintain a healthy weight.
In this episode, Jessica breaks down the science of the vagus nerve in a practical, easy-to-understand way specifically for nurses and busy professionals.
You’ll learn:
• What the vagus nerve is and where it runs in the body
• How the vagus nerve connects the brain, gut, metabolism, and emotional regulation
• Why nurses and shift workers are especially vulnerable to nervous system dysregulation
• How chronic stress impacts blood sugar, inflammation, and weight regulation
• The connection between vagal tone, digestion, insulin response, and cravings
• Why metabolism is deeply connected to nervous system health — not just calories or exercise
• Simple, practical ways nurses can begin improving vagal tone even during busy shifts
Jessica also shares practical nervous system regulation techniques including breathing exercises, humming, cold exposure, and other simple strategies that help signal safety to the body and support metabolic balance.
If you are a nurse struggling with stress, fatigue, burnout, emotional eating, or weight fluctuations, this episode will help you understand why your body may feel stuck in survival mode — and what you can start doing to support healing.
Because metabolism is not just about food.
It’s about the nervous system, stress physiology, sleep, inflammation, and how safe the body feels day to day.
Jessica’s mission through Proactive Wellness is to help nurses reclaim their health, regulate their nervous systems, and rebuild metabolic resilience so they can feel energized, balanced, and supported both inside and outside of the healthcare environment.
