Peptides: The Chemistry of Emotion and How Sound Can Help Us Rewire

Ever feel like your body reacts before your mind can explain it?That might not be anxiety or habit.It might be peptides—tiny emotional messengers locked into your cells.

For years, I thought my tendency to overthink and overprepare was just part of who I was.

Anxious. Hyperaware. Always scanning.

But over time, I started to realise—this wasn’t just psychological.It was biochemical.

What Are Peptides?

Peptides are tiny molecules that carry emotional signals between your brain and body.

Every time we feel something—joy, fear, sadness, rejection—our brain releases neuropeptides that lock into receptors across the body: in the gut, the heart, the muscles, even the immune system.

Think of peptides like emotional postmen—delivering the same message over and over until your body builds its identity around it.

So when you feel something often enough, your body starts to expect it.It becomes a loop.A chemical echo of your past.

When Emotion Becomes Habit

I didn’t understand it at the time, but from a young age my body was absorbing stress on repeat.

• Hiding in the house to avoid bullies in the street.

• Bracing for the teasing and ridicule as soon as I stepped into a classroom.

• Managing the emotional weather at home—young parents arguing, never knowing what version of them I’d meet that day.

And while I’ve since come to understand that I’m autistic and have ADHD, what I really learned back then was how to mask.

To perform calm.To appear in control.Even when my body was screaming “I’m not safe.”

Those years shaped me. But they also shaped my chemistry.

The Body Gets Addicted to Emotion

Here’s the thing: peptides don’t just carry emotions—they help reproduce them.

If your body’s been flooded with the same signals for years—fear, shame, stress—it starts to crave those states.Not because you want to suffer.But because that’s what feels familiar.

Your body begins to react to life not as it is, but as it’s been trained to.

That’s why sometimes, even in safe spaces, I find myself tense. On edge.Still scanning the room.Still waiting for the next hit.

How Sound Offers a Way Through

You can’t think your way out of a peptide loop.But you can re-pattern it.

That’s what sound did for me.

When I hum, chant, or lie beneath the gong, my body starts to remember a new rhythm.One that isn’t stress or survival.But stillness.Safety.Presence.

What Sound Might Be Doing

While the science is still catching up, we know that sound:

🔹 Travels through water and tissue—stimulating the nervous system

🔹 Activates the parasympathetic state—the place of rest, digestion, and healing

🔹 May influence peptide-producing glands like the hypothalamus and pituitary

More importantly, sound offers the body a new sensory signature.

A different feeling.A different chemistry.

What I See in Practice

In my sessions, I see people soften in ways they didn’t know they needed:

• Shoulders dropping for the first time in years

• Deep sighs without prompting

• Tears arriving before stories

• Smiles returning without effort

This is more than relaxation.It’s chemical repatterning.And the body leads the way.

Let’s Leave You with This

If you feel stuck in emotional patterns that don’t match your life now…If your body keeps pulling you back into loops you thought you’d outgrown…If your mind says “you’re safe” but your cells haven’t caught up—

It might be the peptides talking.

🖤Let sound speak back to them.Let your body feel something new.Let it remember:

You are not your trauma.

You are not your chemistry.

You are not your past.

You are the awareness beneath it all.

And you are allowed to rest.
