The Vagus Nerve Explained: Calm Your Body & Rewire Stress

Chronic stress has become so normal that many of us no longer recognise when our nervous system is stuck in survival mode. If you feel wired but exhausted, struggle to switch off, experience poor sleep, anxiety, or constant overwhelm, the issue may not be mindset — it may be nervous system dysregulation.In this episode of The Health Review, Emily speaks with Jane Ollis — medical biochemist, environmental scientist, Oxford business fellow, and founder of SONA, an AI-powered vagus nerve stimulation platform designed to retrain the body’s stress response.Together, they explore how the nervous system really works, why modern life keeps us stuck in fight-or-flight, and what it actually means to feel calm and regulated. Jane explains the role of the vagus nerve, heart rate variability (HRV), and autonomic balance — and why true recovery requires retraining the body, not just managing stress.They also discuss the future of adaptive neurostimulation, how personalised technology can support resilience and sleep, and why nervous system regulation may become one of the most important tools in preventive health and performance medicine.🎧 Exclusive listener offer: Jane has kindly offered The Health Review listeners 15% off SONA.
