What’s Really Happening in Your Body During Yoga Nidra & Sound

A Wild Mother Star translation of rest, regulation, and remembrance.

A nerdy love letter to your nervous system.

“I didn’t have a single flare since I joined your classes — not one. Pain is usually constant in my life.”
“I feel peace. Contentment. I just feel… good.”
“I didn’t get the flu this season.”
“I sleep so much better now.”
“It’s weird — I have more tolerance for other people’s bullshit.”

None of this is accidental. None of it is placebo. And none of it is magic — though it may feel magical when the body remembers what it was designed to do.

This is a translation — from sensation to science, from lived experience to biology.

The Big Picture: We Are Living Out of Rhythm

Our nervous system evolved under stars, seasons, firelight, and dark.

It learned safety through rhythm: day and night, effort and rest, sound and silence.

Modern life has flattened those rhythms.

Not with catastrophe — but with constancy.

We are living in a world that forgot the pace of mammals, the wisdom of dusk, the necessity of lying down and listening to the dark.

Most modern bodies are in chronic sympathetic activation.

Not emergency stress — background stress.

Low-grade, constant, humming stress that keeps the body subtly braced:

  • muscles never fully soften
  • digestion is rushed or incomplete
  • sleep is shallow or fragmented
  • immune responses are dysregulated
  • pain pathways stay switched on

Yoga Nidra does not add something to you.

It removes interference.

It guides the body into a state where repair, regulation, and recalibration can occur — because those systems are already built in.

The State Beneath Sleep: Where the Body Remembers How to Repair

During Yoga Nidra, the brain moves into slower rhythms — alpha, theta, sometimes touching delta.

This is the terrain between waking and sleep.

Here:

  • stress hormones reduce
  • parasympathetic tone increases
  • internal organs receive clearer regulatory signals
  • the body reallocates energy from survival to maintenance

This is organised rest.

A state mammals enter naturally, when they feel safe enough.

Sound supports this process through vibration and rhythm, helping the nervous system entrain into coherence.

The body listens.

“I Haven’t Had a single Flare” — Pain, Inflammation & the Nervous System

Chronic pain is not just a tissue story.

It is a nervous system story.

When the brain perceives threat — emotional, relational, or environmental — it amplifies pain signals. This is mediated through:

  • heightened sympathetic tone
  • elevated cortisol
  • increased inflammatory cytokines
  • sensitised pain pathways

Yoga Nidra shifts the body into parasympathetic dominance.

What this means biologically:

  • cortisol output decreases
  • inflammatory signalling softens
  • muscles exit protective guarding
  • pain thresholds increase

Pain doesn’t disappear because it’s “ignored.”

It quietens because the body no longer needs to shout.

“I Feel Peaceful” — Neurochemistry of Safety

Peace is not a personality trait.

It is a neurochemical state.

During Yoga Nidra, the brain transitions into slower wave patterns (alpha, theta, sometimes delta). In this state:

  • GABA activity increases (the brain’s primary inhibitory neurotransmitter)
  • stress hormones reduce
  • serotonin and dopamine balance stabilises

Sound further supports this by:

  • entraining brainwaves through rhythm and vibration
  • stimulating the vagus nerve via auditory pathways
  • creating a coherent sensory field the brain can rest into

“I Didn’t Get Sick This Year” — Immunity Loves Rest

The immune system is exquisitely sensitive to stress.

Chronic stress:

  • suppresses certain immune responses
  • overactivates others
  • increases susceptibility to infection

Deep rest reverses this.

In parasympathetic states:

  • immune cells communicate more efficiently
  • inflammation becomes regulated rather than reactive
  • the body allocates energy toward maintenance instead of survival

“I Sleep So Much Better” — Teaching the Brain to Let Go

Sleep problems are rarely about discipline or willpower.

They are about nervous system timing, trust and letting go.

Yoga Nidra:

  • lowers baseline arousal
  • trains the brain to enter restorative states consciously
  • improves melatonin–cortisol rhythm synchronisation

Many people experience deeper sleep not because they are “more tired,” but because their nervous system finally trusts that it is safe to let go.

“I Have More Tolerance for Other People’s Bull**it” — Emotional Regulation & the Prefrontal Cortex

This one always makes me smile.

Because tolerance is not a moral virtue.

It’s neural bandwidth.

When the nervous system is overloaded:

  • the amygdala (threat centre) dominates
  • reactivity increases
  • patience disappears

Yoga Nidra strengthens top-down regulation:

  • increased prefrontal cortex engagement
  • reduced amygdala reactivity
  • improved emotional integration

The Wild Mother Truth: Regulation Is Remembering

Your body remembers how to heal.

Your nervous system remembers rhythm.

Your cells remember cycles of rest and repair.

Yoga Nidra is not an escape from life.

It is a return to biological intelligence.

A remembering.

Not to be fixed.

But to be re-attuned.

This is not about becoming calm forever.

It’s about becoming responsive instead of reactive.

And that changes everything.

A Gentle & Important Note (Because Integrity Matters)

Yoga Nidra and sound work are well‑researched practices for nervous system regulation, stress reduction, and wellbeing.

They are not medical treatments, and they do not replace medical care, diagnosis, or medication.

What they do offer is something profoundly biological and often missing in modern life:

sustained conditions of safety, rest, and regulation — the foundation upon which healing processes can function.

If you are living with illness, pain, trauma, or long‑term conditions, these practices work alongside other forms of support, not instead of them.

Curious to Experience This in Your Own Body?

Reading about regulation is one thing.

Feeling it — is another.

I offer regular Yoga Nidra & Sound Bath sessions and 1:1 sound massage locally, created for people who:

  • live with stress, pain, or nervous system overwhelm
  • want deeper sleep and emotional steadiness
  • are craving rest that actually does something

These sessions are slow, spacious, trauma‑aware, and deeply grounding — designed to meet real bodies living real lives.

If you’re nearby and feel the quiet pull to lie down, listen, and let your system recalibrate — you are warmly welcome.

You don’t need to understand the science first.
