The Psoas and Diaphragm: The Deep Connection Between Breathing, Tension and the Body

The psoas is a deep muscle connecting the lumbar spine to the upper thigh. It plays an important role in hip movement, posture, spinal stability and nervous system regulation. The diaphragm, our primary breathing muscle, sits just above it, separating the chest from the abdominal cavity.

Have you ever noticed that when you feel stressed, your breathing becomes shallow, your belly tightens, or your lower back starts to ache?

There is a fascinating connection between two deep structures in our body: the psoas muscle and the diaphragm.

Although they have different functions, these structures are anatomically connected through their attachments and surrounding connective tissues. They work together to support movement, postural stability and the mechanics of breathing.

When the body holds tension

During periods of prolonged stress, we may unconsciously change the way we breathe, brace our abdomen or hold tension around our hips and lower back. Over time, these patterns can influence how freely we move and breathe.

The body is not separate from the mind. Our emotional experiences, physical habits and nervous system responses can all influence our breathing and muscle tension. The psoas muscle has a strong connection with our sympathetic response and fight/flight response.

Sometimes, what we need is not to push harder or stretch further, but to slow down and allow the body to soften or to release a freeze response that rob us from joy and vitality.

Creating space for ease

Through mindful craniosacral therapy, we can invite greater awareness of these deep patterns of tension. By supporting relaxation, comfortable breathing and a sense of safety in the body, we create an opportunity to experience more ease and freedom of movement and emotional regulation.

When the body finds more space, we may discover more room to breathe, move and reconnect with ourselves to experience joy and vitality.

If you feel that your body has been holding tension for too long, craniosacral therapy offers a gentle space to slow down, reconnect with your body and support your natural sense of balance and vitality.
