The human body has an incredible built-in system designed to help us recover from stress and return to a state of balance.

At the centre of this system is the vagus nerve.

The vagus nerve is the longest cranial nerve in the body and plays a key role in regulating the nervous system. It connects the brain to many important organs, including the heart, lungs, and digestive system.

Because of this wide network, the vagus nerve influences many aspects of our health — from stress response and emotional regulation to digestion, heart rate, and even immune function.

When the vagus nerve is functioning well, the body is better able to shift from states of stress into states of rest and repair.

What Does the Vagus Nerve Do?

The vagus nerve is a central part of the parasympathetic nervous system, often described as the body’s “rest and restore” system.

While the sympathetic nervous system prepares us for action and alertness, the parasympathetic system helps us slow down and recover.

Through its many connections in the body, the vagus nerve helps regulate:

• Heart rate
• Breathing patterns
• Digestion
• Inflammation
• Emotional regulation
• Stress recovery

This is why practices that support vagal tone — the strength and responsiveness of the vagus nerve — can have such a powerful effect on overall wellbeing.

Why Vagal Tone Matters

Vagal tone refers to how effectively the vagus nerve can respond and help the body return to calm after stress.

Strong vagal tone allows the nervous system to move flexibly between activation and relaxation.

When vagal tone is low, people may find it harder to recover from stress. They may experience symptoms such as:

• Chronic tension or anxiety
• Digestive discomfort
• Fatigue or burnout
• Difficulty relaxing
• Heightened stress responses

Supporting the vagus nerve can help restore balance and improve the body’s ability to regulate itself.

Ways to Support the Vagus Nerve

The good news is that the vagus nerve can be gently supported through simple daily practices that signal safety to the nervous system.

Some supportive approaches include:

Slow breathing
Deep, slow breathing helps activate the parasympathetic nervous system and calm the body.

Cold water exposure
Splashing the face with cold water or brief cold exposure can stimulate the vagus nerve.

Humming or singing
The vagus nerve runs near the vocal cords, so humming or singing can help stimulate it.

Gentle movement
Practices such as yoga, walking, or stretching support nervous system regulation.

Relaxation therapies
Many people find that calming therapies encourage the nervous system to shift into a more relaxed state.

A Nervous System That Feels Safe

One of the most powerful ways to support the vagus nerve is through experiences that help the body feel safe.

Safety signals might include:

• quiet environments
• warm lighting
• time in nature
• supportive human connection
• moments of stillness

When the nervous system receives these signals regularly, the vagus nerve helps guide the body back toward regulation.

A Gentle Reminder

Many people living with chronic stress or burnout believe something is “wrong” with them.

But often, the nervous system has simply been under pressure for too long.

Learning about the vagus nerve can help us understand that the body is not broken — it is simply trying to protect us.

With time, support, and gentle care, the nervous system can begin to find its way back to balance.
