The vagus nerve is one of the most important nerves in the body. It runs from the brainstem through the neck and chest to the abdomen, and helps regulate functions like breathing, digestion, and heart rate. In recent years, the idea of ‘vagus nerve hypersensitivity’ has appeared in wellness circles, with claims about its role in a wide range of health conditions. But what does the science actually say?
What is the vagus nerve?
The vagus nerve is part of the parasympathetic nervous system — the ‘rest and digest’ side of the body’s control system. It influences breathing, digestion, heart rate, and inflammatory responses.
What do people mean by ‘vagus nerve hypersensitivity’?
Some sources suggest that an ‘overactive’ or ‘sensitive’ vagus nerve could be linked to symptoms like dizziness, fainting, digestive changes, or stress-related issues. However, in most medical literature, the vagus nerve is more often discussed in terms of underactivity rather than hypersensitivity.
What does the research say?
Research does show that vagus nerve stimulation (through medical devices or techniques like deep breathing) can influence health in meaningful ways, particularly in conditions such as epilepsy, depression, and inflammatory disorders. However, the concept of ‘hypersensitivity’ is not well defined in clinical research.
Common Myths vs. Facts
– Myth: The vagus nerve causes most cases of anxiety. Fact: While it plays a role in calming the body, anxiety is influenced by many systems.
– Myth: A chiropractor can directly adjust the vagus nerve. Fact: Chiropractic care may influence posture, spinal function, and stress, which in turn can affect how the nervous system operates, but the vagus nerve itself is not something that can be directly adjusted.
– Myth: All digestive issues are vagus nerve problems. Fact: Digestion involves multiple organs and systems, not just the vagus nerve.
How does this connect to chiropractic care?
In practice, many patients under high stress show patterns like shallow breathing, muscle tension, and poor posture — all of which can influence how the nervous system, including the vagus nerve, responds. Chiropractic care can support better posture and movement, which may reduce some of the indirect stresses on the nervous system.
Vagus Nerve Awareness in Johannesburg
In Johannesburg, patients are increasingly curious about nervous system health. While ‘vagus nerve hypersensitivity’ is not a formal diagnosis, it reflects growing awareness that stress and lifestyle can shape how the body feels and functions.
Frequently Asked Questions
What is the vagus nerve?
It is a major nerve of the parasympathetic nervous system that helps regulate heart rate, breathing, digestion, and more.
Is vagus nerve hypersensitivity a real diagnosis?
Not in most medical literature. The term is used in wellness discussions, but research usually focuses on vagus nerve underactivity or stimulation.
Can chiropractic care adjust the vagus nerve?
No, chiropractors don’t adjust nerves directly. However, improving posture and reducing stress on the body can influence how the nervous system functions overall.
What are safe ways to support vagus nerve function?
Breathing exercises, stress management, good posture, and in some cases medical vagus nerve stimulation have been studied as ways to support healthy function.
