Your posture is sending your brain a message right now. The question is - what is it saying?

Most of us think about posture as something aesthetic. We know we should probably sit up straighter or stop hunching over our phones. But according to Dr Naomi Christmas from Avia Chiropractic, posture is far more than how we look - it's one of the most constant inputs your nervous system receives, shaping your stress response, your breathing, and your capacity to recover.

Ahead of her Kōra Circle on 28th March, we asked Dr Naomi five questions to help you understand why this conversation matters -  and what it could mean for the way you move, rest, and regulate.

Most of us have heard "sit up straight" our whole lives; but you approach posture in a completely different way. Can you explain what posture actually has to do with our nervous system?

Posture isn’t about “sitting up straight.” It’s how your nervous system organises your body.

Your brain is constantly deciding:

• Am I safe?

• Do I need to brace?

• Do I need to protect?

If it senses stress (physical or emotional), it increases muscle tension. That tension changes how you sit, stand, and move.

So posture is less about discipline, and more about how regulated your system is.

If someone came to you and said "I'm not stressed, I just feel constantly tight and tense" = what would you want them to know?

Constant tightness is often your body being on guard.

You might not feel mentally stressed.
But your body can still be running in the background on “alert mode.”

When that happens:

• Muscles stay slightly switched on

• Breathing becomes shallow

• Stretching only works temporarily

Tight doesn’t always mean short. It often means protective.

We tend to think of stress as something we feel emotionally. What does chronic stress actually look like in the body, and why do so many people miss the signs?

Chronic stress rarely feels dramatic.

It can look like:

• Always tight shoulders

• Clenched jaw

• Shallow breathing

• Fatigue

• Headaches

• Digestive issues

• Trouble switching off at night

It becomes normal, so people don’t recognise it as stress. Your body adapts to tension and calls it baseline.

The word "chiropractic" makes most people think of backs and necks = not nervous system regulation or breathing. How are they connected?

Your spine isn’t just bones. It’s full of sensors that talk to your brain.

When joints move well, your brain gets clearer information. When they don’t, tension patterns can build.

Breathing is part of this too. Your diaphragm helps you:

• Breathe

• Stabilise your spine

• Calm your nervous system

So spine, breath, and stress response are all connected.

For someone who moves regularly and feels relatively healthy, why should they still care about the relationship between their posture, their breath, and their stress response?

Because being fit doesn’t always mean being regulated.

You can train hard and still:

• Hold unnecessary tension

• Breathe inefficiently

• Recover slower than you should

The goal isn’t perfect posture. It’s adaptability.

A healthy system can switch between effort and recovery easily.

That’s what builds long-term resilience.
