What Is the Vagus Nerve?

Written By Creatives Restore

Understanding its role in the body and why it matters for children’s wellbeing.

The vagus nerve is one of the body’s most important communication pathways. It plays a central role in how the brain and body communicate, particularly around functions we do not consciously control, such as digestion, heart rate, breathing, and aspects of emotional regulation.

Because of its wide-reaching role, the vagus nerve is often discussed in conversations about the gut-brain connection, stress responses, and nervous system regulation.

Understanding the vagus nerve can help parents make sense of how different body systems are connected, especially in children who may experience challenges with digestion, sleep, emotional regulation, or general wellbeing.

What Is the Vagus Nerve?

The vagus nerve, also known as the tenth cranial nerve (CN X), is the longest of the cranial nerves.

It begins in the brainstem and travels through the neck, chest, and abdomen, connecting the brain to many major organs along the way.

The name “vagus” comes from the Latin word for “wandering,” which reflects its long and varied path throughout the body.

What Does the Vagus Nerve Do?

The vagus nerve has several important roles, including sensory, motor, and autonomic functions.

Sensory functions. It carries information from the body back to the brain, including signals from the throat, heart, lungs, and digestive organs.

Motor functions. It helps control muscles involved in swallowing and vocal function.

Autonomic functions. As part of the parasympathetic nervous system, it helps regulate many automatic body processes, including:

  • heart rate

  • breathing

  • digestion and gut motility

  • inflammatory responses

  • aspects of mood and emotional regulation

Because it is involved in communication between the gut and the brain, the vagus nerve is also an important part of what researchers call the gut-brain axis.

Why Is the Vagus Nerve Important?

The vagus nerve contributes to the body’s ability to shift into a calmer, more restorative state.

This more restful state is often associated with:

  • improved digestion

  • slower heart rate

  • more settled breathing

  • better recovery from stress

When the body is under ongoing stress, researchers suggest this balance can be affected. Because the vagus nerve is involved in many body systems, changes in nervous system regulation may be reflected in different ways from person to person.

Signs That May Be Associated With Nervous System Dysregulation

Because the vagus nerve is involved in so many body functions, challenges in regulation may sometimes be seen alongside:

  • digestive discomfort, constipation, reflux, or abdominal pain

  • sleep difficulties

  • heightened stress responses

  • emotional regulation difficulties

  • sensory sensitivities

  • feelings of dizziness or fluctuations in heart rate

These signs can have many different causes, and they should always be assessed in context by appropriate healthcare professionals.

The Vagus Nerve and Children’s Health

In children, the vagus nerve is often discussed in relation to:

  • digestion and bowel function

  • feeding and swallowing

  • sleep and settling

  • emotional regulation

  • the body’s recovery from stress

Researchers are continuing to study how the autonomic nervous system, including the vagus nerve, may relate to a wide range of childhood health experiences.

It is important to remember that children’s health is complex and influenced by many factors including genetics, development, environment, family circumstances, and access to care.

The Gut-Brain Connection

One of the most talked-about roles of the vagus nerve is its involvement in the gut-brain axis.

This refers to the two-way communication between the digestive system and the brain.

The vagus nerve helps carry information between these systems, which is why digestion, stress, and mood can sometimes seem closely linked.

Research in this area continues to grow, particularly in relation to how the nervous system, microbiome, and immune system interact.

Stress, Regulation, and the Nervous System

The body’s stress-response systems are designed to help us respond to challenges. However, when stress becomes frequent or prolonged, it can affect how easily the body returns to a more settled state.

The vagus nerve plays a role in helping the body shift back toward rest and recovery.

Supporting a child’s overall wellbeing therefore often includes supporting their nervous system through:

  • consistent routines

  • adequate sleep

  • movement and outdoor play

  • nourishing food

  • supportive relationships

  • calm, predictable environments

Where Chiropractic Care May Fit In

Some families choose to include chiropractic care as part of their child’s broader wellbeing plan.

Chiropractic care focuses on musculoskeletal health, posture, movement, and general wellbeing.

For children, care is typically very gentle and may be sought to support:

  • physical comfort

  • movement and posture

  • general wellbeing

Some chiropractors also use non-invasive tools to observe patterns in physiological responses, such as tension or heart rate variability. These tools may provide additional information about how the body is functioning, but they do not diagnose medical conditions.

*Chiropractic care is not a treatment for vagus nerve disorders, neurological disorders, autism, seizures, or other medical conditions, and should always be considered alongside appropriate medical and allied health care.

A Collaborative Approach to Children’s Wellbeing

Because the vagus nerve is connected to many aspects of health, families often benefit from a collaborative approach that may include:

  • GPs

  • paediatricians

  • psychologists

  • occupational therapists

  • speech pathologists

  • dietitians

  • chiropractors and other allied health professionals

Working together helps ensure children receive well-rounded, appropriate support.
