The Psoas: The Muscle of Stress, Safety & Deep Release

Pause. Breathe. Restore.

Lately, I’ve been noticing a pattern in the treatment room.
More and more clients are arriving with deep, persistent tightness that doesn’t quite behave like a typical muscular issue.

It sits deeper.
It feels harder to reach.
And often… it doesn’t respond well to pressure.

More often than not, we’re talking about the psoas muscle.


Where is the Psoas?

The psoas (pronounced so-az) is a deep core muscle that sits inside the body, not on the surface like many of the muscles we massage.

It:

  • Starts at your lower spine (lumbar vertebrae)
  • Travels through the pelvis
  • Attaches to the top of your thigh (femur)

You actually have two — one on each side — and together with the iliacus muscle, they form the iliopsoas, your primary hip flexor.

What Does It Do?

The psoas is involved in:

  • Walking, running, and climbing stairs
  • Lifting your legs
  • Stabilising your spine and pelvis
  • Supporting posture and core balance

But it’s not just mechanical…

The psoas is also deeply connected to your nervous system.

The Psoas & Stress: Why So Many Are Tight

The psoas is often called the “muscle of the soul” — not because it’s mystical, but because of how closely it’s linked to your fight-or-flight response.

When you’re stressed, overwhelmed, rushing, or constantly “on”…
your nervous system activates — and your psoas contracts.

This is ancient biology.
It’s the muscle that prepares you to:

  • Curl into protection
  • Run
  • React

The problem is… modern life doesn’t give us a clear “off” switch.

So the psoas stays slightly contracted.
Day after day.

Over time, this can show up as:

  • Lower back pain
  • Hip tightness
  • Pelvic discomfort
  • Digestive tension
  • A feeling of being “held” or unable to fully relax

Why Deep Pressure Isn’t Always the Answer

Because the psoas is:

  • Deep
  • Sensitive
  • Closely linked to the nervous system

…it doesn’t respond well to force.

In fact, aggressive techniques — like very deep pressure or massage guns — can sometimes cause it to tighten further as a protective response.

Instead, the psoas responds best to:

  • Gentle, respectful touch
  • Slow, intentional work
  • A sense of safety

This is why treatments that focus on calming the body — rather than forcing release — are often far more effective.

What Is the Psoas Connected To?

The psoas is at the centre of a web of connections.

It links to:

  • The diaphragm (your main breathing muscle)
  • The spine and nervous system
  • The pelvis and pelvic floor
  • The hips and legs

This means tension in the psoas can ripple through the whole body.

And equally…
when you support one area (like breathing), you can influence the psoas too.

Breathing: The Key to Releasing the Psoas

Because of its connection to the diaphragm, one of the most powerful ways to support the psoas is incredibly simple:

Breathing.

Slow, deep, diaphragmatic breathing helps to:

  • Signal safety to the nervous system
  • Reduce fight-or-flight activation
  • Allow the psoas to soften naturally

Try this:

A simple 2-minute reset

  • Lie on your back with knees bent
  • Place one hand on your chest, one on your belly
  • Inhale slowly through your nose
  • Let your belly rise gently
  • Exhale slowly through your mouth
  • Repeat for 2–5 minutes

No forcing.
No fixing.
Just allowing.

How Massage Can Help

In treatments at Sanare, this often looks like:

  • Slowing everything down
  • Working with the breath
  • Supporting the body rather than pushing it
  • Creating a space where the nervous system can soften

Sometimes, the most powerful shifts happen not through pressure…
but through permission to let go.

A Gentle Reminder

If your body feels tight, resistant, or “stuck”…
it may not need more force.

It may need:

  • Safety
  • Stillness
  • Space
  • Breath

Your body isn’t working against you.
It’s protecting you.

And when it feels safe… it will soften.

Pause. Breathe. Restore. ✨
