How Breathing Dysfunction Causes Pelvic Floor Tension (And What to Do About It)

You've been told you have a "tight pelvic floor." You've done the stretches, the breathing exercises, maybe even biofeedback. But nothing changes—or it gets worse.

Here's what's probably happening: your pelvic floor isn't the problem. Your breathing is.

The Breath-Pelvic Floor Connection

Your pelvic floor and diaphragm work as a coordinated team. When you inhale, your diaphragm descends and your pelvic floor should gently lengthen. When you exhale, both return to resting position.

This is called the "piston effect," and when it's disrupted, your pelvic floor bears the burden.

Common Breathing Patterns That Create Pelvic Tension

Chest breathing (apical breathing): When you breathe primarily into your upper chest rather than your belly, your diaphragm can't fully descend. Result? Your pelvic floor never gets the lengthening signal and stays perpetually contracted.

Breath holding: Many people hold their breath during daily activities without realizing it—typing emails, driving, concentrating. This chronic breath-holding keeps your entire core, including your pelvic floor, in a constant state of tension.

Paradoxical breathing: This is when your belly pulls in on inhale instead of expanding out. It reverses the natural piston effect and creates chronic pelvic floor dysfunction.

Hyperventilation/anxiety breathing: Rapid, shallow breathing keeps your nervous system in fight-or-flight mode, which automatically increases pelvic floor tension as a protective response.

Why Your Ribcage Mobility Matters

Here's what most pelvic floor therapists miss: if your ribcage can't expand fully, your diaphragm can't move properly, and your pelvic floor pays the price.

Common ribcage restrictions come from:

- Previous rib injuries or costochondritis

- Thoracic spine stiffness

- Poor posture (forward head, rounded shoulders)

- Scar tissue from abdominal or chest surgeries

We routinely find significant thoracic spine and rib restrictions in patients with "tight pelvic floors." Treat the ribcage, breathing improves, pelvic floor relaxes.

The Cervical Spine Connection

Your neck position directly affects your breathing mechanics. Forward head posture (which almost everyone has from phones and computers) shortens the scalene muscles in your neck, which are accessory breathing muscles.

When your scalenes are chronically short and tight:

- They pull your first rib up, restricting thoracic expansion

- They contribute to chest breathing patterns

- They create a cascade of tension down your entire body

This is why we always assess and treat the neck in patients with pelvic floor tension—even when they never mentioned neck pain.

Assessment: How's Your Breathing?

Try this simple test:

1. Lie on your back with knees bent

2. Place one hand on your chest, one on your belly

3. Breathe normally for 10 breaths

4. Notice which hand moves more

Ideal pattern: Belly hand moves more than chest hand on inhale. Both hands should move smoothly and rhythmically. You should also feel your rib cage move as you breathe and should feel the pelvic floor lengthen.

Dysfunction patterns:

- Chest hand moves more (chest breathing)

- Belly pulls in on inhale (paradoxical breathing)

- Breathing feels effortful or irregular

- You can't take a full, easy breath

Simply telling someone to "breathe into your belly" rarely works if the underlying mechanical restrictions haven't been addressed.

When to Seek Professional Help

If you've been doing pelvic floor exercises or breathing work for weeks without improvement—or if things are getting worse—the problem is likely mechanical restrictions that require skilled treatment.

At Renew Health, we assess the entire system: cervical spine, thoracic spine, ribcage, diaphragm, and pelvic floor. We find and treat the primary driver, not just the symptoms.
