Where Your Body Stores Stress, and How to Release It After 40

 

You used to be able to handle so much stress in your life and just keep going. Now your shoulders are permanently up around your ears, your sleep is unreliable, your digestion has opinions it never used to have, and none of it traces back to anything specific that happened this week.

Dr. Carli Axford, a chiropractor with 30 years of clinical experience and the founder of the Spinal Flow Technique, has a theory about why: your body may be holding the physical residue of stress it never got the chance to finish processing, some of it decades old.

 

This is for you if you've been thinking:

  • I used to be able to handle so much more than I can now, and I don't understand what changed.

  • I have a knot between my shoulder blades that has been there for years and no massage ever fixes it.

  • My digestion started acting up in my forties and every test comes back normal.

  • I'm exhausted all day and then wired the second my head hits the pillow.

  • I've heard people say the body stores stress and I want to know if there is anything physiological behind that or if it's just a saying.

  • I don't feel especially stressed right now, so I can't figure out why my body is acting like I am.

  • I've been told my back pain is from bad posture, but it started around the same time as a hard year in my life.

What "Your Body Stores Stress" Actually Means

Carli's explanation starts with a reframe of a phrase you have used a hundred times. When something happens that you cannot deal with, you put it to the back of your mind. She argues that the back of your mind is not a metaphor. It's your spine.

Here's the physiology she walks through. Your brain sits inside bone, which tells you how much your body values it. Pull the brain out and it comes attached to the spinal cord, one continuous organ, with nerves branching to every organ, cell, tissue, and muscle you have. Surrounding that spinal cord are 33 movable vertebrae. When your nervous system detects a threat, whether that's a genuine emergency or your inbox, it moves you into fight or flight. The signal starts in the brain, travels down, and the vertebrae lock together to brace you. Digestion slows. Reproduction goes on hold. Everything reroutes toward running.

That response is supposed to be temporary. The problem is what happens when you never come back. Carli describes the body making a deal with you: I can't process this right now, so I'll hold it, and you come get it later. For a lot of us, later never comes. The bracing stays. And she is careful to say she cannot separate bone from nerve from muscle from organ in this, because they function as one integrated system. What she can say is that the holding pattern starts in the brain and shows up everywhere else.


The Three Kinds of Stress, and What They Feel Like

Carli separates stress into three categories: physical, chemical, and emotional. Physical stress is the bending, twisting, lifting, and impact your body absorbs. Chemical stress is anything coming in that your body cannot process through its normal channels, including pesticides, alcohol, caffeine, medications, and also viruses and bacteria generated internally. Emotional stress is any experience that carried more feeling than you could metabolize at the time.

The interesting part is that she says they feel physically different under her hands. Chemical stress sits closer to the surface and feels squishy, which she describes as marshmallow-like. Emotional stress sits deeper, right at the spine, and feels ropey and hard. She also maps stress to seven regions of the spine, which she calls gateways. Physical trauma tends to settle low, around the pelvis. A painful memory tends to settle in the thoracic spine, behind the heart.

Over years of practice, she kept seeing people arrive with digestive complaints, irritable bowel, Crohn's, gluten problems, and finding a blockage in the lumbar spine. But when she felt deeper, the older pattern was in the thoracic spine, behind the heart. Her interpretation is that when one region locks up, another region compensates and takes on more load. The place that hurts is not necessarily where the problem started. 

A note on evidence: some of this is established physiology, the fight or flight response, the nervous system's control over digestion, the way compensation patterns develop. The mapping of specific emotions to specific spinal regions comes from Carli's own clinical observation across three decades, not from published research. She is upfront that she works from what she feels and sees. Take it as a practitioner's pattern recognition rather than a proven mechanism, and see whether it matches your own experience.


Why It Catches Up With You in Your 40s and 50s

The short answer is that it is cumulative. Carli tells the practitioners she trains to go feel a two-day-old baby's spine so they know what a body with no stored stress feels like, then feel an adult spinel. Her description is that the way the body stores stress is like the layers of an onion. Layer on layer on layer, plus all the secondary compensations that build up around each layer.

Then perimenopause arrives and removes some of the cover. Carli's framing is that fluctuating and declining estrogen and progesterone act like a mirror. For years your hormones were smoothing things over and letting you push through. When that support changes, your resilience drops and everything you have been carrying becomes visible at once. This is why women often describe midlife stress as a new problem when it is more accurately an old problem you can finally feel.

She is also direct about the fact that being good at handling stress is not the same as recovering from it. You can cope beautifully, mentally, for decades while your body never gets to complete the cycle. That gap is why so many capable women say they are not stressed while their bodies are clearly reporting otherwise.


How to Tell a Pulled Muscle From Something Older

Jessica asked her a question you have probably asked yourself. There's a knot between my shoulder blades. Is that from my workout, or is that emotional?

Carli's answer is refreshingly practical: use time. A physical injury, a strain or a sprain or a small tear, has a healing timeline. It might stick around four, five, six weeks, and then it goes. It does not hold a story and it does not change your nervous system. If you trace the same spot back and realize it was there a year ago, and a few years before that, you are looking at something older.

Her second suggestion is to ask the area a question. In a calm moment, during breathwork or afterward, put your attention on the spot and ask how it makes you feel. Sometimes nothing comes. Sometimes there's a flood, or a specific age, or a memory you had not thought about in years. She frames that as giving the area a voice, and says that noticing it is sometimes the whole intervention.

Worth saying plainly: not every symptom is stored stress. If something is new, worsening, or accompanied by anything alarming, get it looked at medically. Carli emphasized the importance of having a medical team lined up. 


What to Do About It, With or Without a Practitioner

Carli's honest bias is that this is easier with a practitioner. Her preference is a Spinal Flow Technique practitioner, and there is a directory on her site to find one near you. But she was notably unwilling to tell you a chiropractor is better than a physio or an osteopath. Her actual advice on choosing someone is about the human, not the credential. Find the person you trust, whose explanation makes sense to you, and whose presence lets your nervous system settle when you talk to them. Call a few. Notice how you feel. That is the criteria.

For everything you can do on your own, her answer is breath, and she knows how that sounds. Her argument for why it is not throwaway advice: when you are in fight or flight, your sympathetic nervous system is running the show and your body is storing stress, not releasing it. It is not doing repair work because it does not believe it is safe enough to. Breath is the fastest available switch into the parasympathetic state, where healing and digestion actually happen. Cut your finger and it heals on its own. That capacity is always there. It just needs the right conditions.

Practically, she suggests bringing breath and attention through the whole length of your spine rather than only into your chest, and moving each vertebra, since the spine is a continuation of your brain. It takes minutes, not an hour. You can do it in the car, on a walk, or at your desk. Her closing point was less about technique and more about permission: you are the one deciding your body matters enough to spend five minutes on.

FAQs

Where does the body store stress?

According to Dr. Carli Axford, a chiropractor with 30 years of clinical experience, stress is stored in the spine and nervous system rather than in any single tissue. When the brain detects a threat, it signals the vertebrae to lock together as a protective bracing response, which in turn affects the muscles, nerves, and organs connected to that region. She identifies seven regions of the spine, which she calls gateways, and observes that different kinds of stress tend to settle in different places. Physical trauma often settles low, around the pelvis. Emotional experiences that were not processed at the time tend to settle in the thoracic spine, behind the heart. Because the nervous system, spinal column, muscles, and organs work as one integrated system, stress stored in one region typically produces compensation and symptoms in others.

Why does stress affect my body more after 40?

Two things happen at once. The first is accumulation. Stress that was never fully processed does not disappear, it layers, and each layer produces compensations in the regions around it, so the body has progressively less capacity to adapt. The second is hormonal. During perimenopause, estrogen and progesterone fluctuate and eventually decline, which reduces the nervous system's resilience and removes some of the buffer that let you push through for decades. Dr. Axford describes this as a mirror: the stress load was always there, and the hormonal change is what makes it visible. This is why many women experience midlife stress as a sudden new problem when it is more accurately an older accumulation they can finally feel.

How do I know if my back pain is physical or emotional?

Use the timeline. A physical injury such as a strain, sprain, or muscle tear has a healing curve. It may persist for four to six weeks and then resolve, and it does not alter your nervous system or hold a pattern. If you trace the same spot backward and find it was present a year ago, and several years before that, Dr. Axford considers that a sign of stress stored over a longer period rather than an acute injury. She also suggests putting your full attention on the area during breathwork and asking how it feels, since a specific memory, age, or emotion sometimes surfaces. That said, any pain that is new, worsening, or accompanied by other concerning symptoms should be evaluated medically first.

What is the Spinal Flow Technique?

The Spinal Flow Technique is a gentle, non-invasive method developed by Dr. Carli Axford, a chiropractor with more than 30 years of clinical experience, and now practiced by thousands of certified practitioners internationally. The practitioner assesses posture and movement, then uses light touch along the spine to locate what Axford calls blockages, areas where movement is restricted and stress appears to be held. She describes distinguishing chemical stress, which feels superficial and soft, from emotional stress, which feels deeper and more fibrous. The intent is not to adjust or manipulate the spine but to facilitate the body's own capacity to release stored stress patterns. It is worth noting that this framework comes from Axford's clinical observation and training program rather than from published clinical trials.

What can I do at home to release stored stress?

Breathwork is Dr. Axford's primary recommendation for anyone without access to a practitioner, and the mechanism is straightforward. When you are in a sympathetic fight or flight state, your body prioritizes survival over repair, which means it stores stress rather than processing it. Deliberate breathing shifts you into the parasympathetic state, where digestion and healing actually occur. She recommends directing breath and attention along the full length of the spine rather than only into the chest, and adding gentle movement so each vertebra moves. This takes minutes rather than an hour and can be done sitting in your car, at your desk, or on a walk. Consistency matters more than duration.
