More Vagus Nerve stimulation is not always the answer

The vagus nerve has become one of the most talked-about topics in nervous system healing.

And for good reason. It plays a major role in regulation, connection, rest, digestion, recovery, and feelings of safety.

But somewhere along the way, many people began hearing the same message:

“Just stimulate the vagus nerve.”

And the truth is… it’s not always that simple.

The Nervous System has different states

The autonomic nervous system is not simply: stressed or relaxed. It moves through different survival states depending on what the body perceives is happening.

Sometimes the body unsafely mobilises into:

• flight

• fight

• anxiety

• urgency

• hyper-vigilance

  
  

In these moments, calming and regulating practices can be incredibly supportive. But other times, the body goes in the opposite direction. It slows down. This is often referred to as a dorsal vagal shutdown state or unsafe immobilisation.

What Shutdown can feel like:

Shutdown is not relaxation.

It can feel like:

• exhaustion

• numbness

• emotional flatness

• disconnection

• heaviness

• brain fog

• difficulty functioning

• wanting to withdraw from life

From a nervous system perspective, this is still a survival response, and a last-resort option for a system that is overwhelmed or feeling extremely threatened. The body is essentially saying:

“This is too much. We need to conserve energy.”

Why more 'calming' isn't always helpful

This is where many people become confused. If someone is already in a slowed-down, collapsed, shutdown state, adding more heavily sedating or down-regulating practices can sometimes make them feel:

• flatter

• more disconnected

• more fatigued

• less present

The goal is not to 'shut down better'.

This is important. Many people confuse collapse with calm but shutdown is not the same as regulation. A regulated nervous system is able to move between activation and rest appropriately and still has:

• energy

• presence

• responsiveness

• connection

• adaptability.

If the body is already in a dorsal vagal shutdown state, excessive down-regulation or strong vagal stimulation may sometimes leave people feeling worse rather than better.

Signs you may be overdoing Vagal stimulation

Not every nervous system needs more slowing down. If the body is already in a dorsal vagal shutdown state, excessive down-regulation or strong vagal stimulation may sometimes leave people feeling worse rather than better.

Possible signs can include:

• nausea

• dizziness or light-headedness

• lower heart rate

• feeling faint or “floaty”

• excessive fatigue

• brain fog

• emotional numbness

• dissociation or disconnection

• heaviness in the body

• feeling flat or unmotivated

• increased withdrawal from people or life

• feeling more collapsed after regulation exercises

Some people may also notice:

• cold hands and feet

• difficulty concentrating

• needing excessive sleep but still feeling exhausted.

If a regulation practice consistently leaves you feeling:

• more disconnected

• foggy

• exhausted

• numb

• emotionally absent

your nervous system may be asking for something different. Not more force, not more stimulation but perhaps a different direction entirely. This does not necessarily mean the practice is “bad.” It may simply mean your nervous system needs something different in that moment. A body already in shutdown does not always need more sedation. Sometimes it needs safe activation and gentle re-engagement with life.

This can include:

• physical movement like swaying or dancing

• gardening

• walking in nature

• moving furniture

• sorting cupboards and bookracks

• safe connection with safe people

• creative projects that require movement

• not repeating what feels like unsafe connection

True regulation is not about making the body quieter at all costs. It’s about helping the nervous system move toward flexibility, responsiveness, and safety.

Bottom-Up and Top-Down regulation techniques

It’s also important to understand that regulation can happen in different ways.

Bottom-up regulation works from the body to the brain.

This includes:

• breath

• grounding

• movement

• touch

• posture

• vagal practices

• nervous system exercises

These approaches help send signals of safety from the body upward into the brain.

Top-down regulation works from the brain to the body.

This includes:

• awareness

• reframing

• meaning-making

• mindset

• mental processing

• conscious thought and perception

  
  

For example:

• a slow exhale is bottom-up down-regulation.

• a reassuring thought is top-down down-regulation.

Both matter. Depending on the nervous system state, one may be more supportive than the other. Sometimes the body needs movement before the mind can settle and other times the mind needs clarity before the body can relax. True regulation is learning how to work with both.

Remember...

The nervous system is intelligent, and healing is rarely one-size-fits-all. Sometimes the body needs stillness, sometimes it needs safe activation to come back into life again. The art is learning the difference.
