Your Body Has a Communication System —Here’s What Happens When It Gets Interrupted

KEY TAKEAWAYS

• The nervous system controls every function in the body — not just movement, but digestion, immunity, hormones, and healing.

• Subluxations create interference in the brain-body communication channel, affecting every organ connected to that nerve pathway.

• Chiropractic adjustments remove interference so the body’s innate intelligence can restore clear signal flow.

• The pre/post adjustment shift isn’t just muscular — it happens at the neurological level, because the brain itself can finally relax.

Right now, without you doing a single thing, your brain is running the entire show.

Your heart rate. Your digestion. Your immune response. The way your lungs expand and contract with every breath. The way your body fights off an infection, regulates your hormones, and repairs tissue while you sleep. None of that requires your conscious attention — and all of it depends on one thing: a clear, uninterrupted signal flowing between your brain and your body.

That signal is your nervous system. And when it’s free of interference, your body does exactly what it was designed to do — function, adapt, and heal from within. When it isn’t? Everything downstream suffers. Not just your back. Everything.

What Is the Spinal Cord and Why Does It Control Everything?

Your brain is the command center of your entire body. Every organ, every muscle, every cell — all of it is in constant, two-way communication with your brain through a vast and intricate network of nerves. At the center of that network is your spinal cord: a dense bundle of nerve tissue running from the base of your skull all the way down through your spine, carrying messages in both directions every single second.

When you decide to move your hand, the instruction travels from your brain, down the spinal cord, through the nerve roots, and out to your muscles. When you touch something hot, the message races back up the same highway so your brain knows exactly what to do — and does it before your conscious mind even registers what happened. When your stomach needs to digest your lunch, your heart needs to adjust its rhythm, or your immune system needs to mobilize against a threat, it all happens through this same network.

This is not background noise. This is the foundation of every function you have.

Your spine exists, in large part, to protect this highway. The 33 vertebrae surrounding your spinal cord are armor — flexible enough to allow full range of motion, strong enough to shield those nerve pathways from the physical demands of daily life. But that protection has a vulnerability built into it: the joints, discs, and vertebrae that protect the nervous system can also, under the right conditions, become a source of interference to it.

“Pre-adjustment there is static, tension, and dysfunction. Post-adjustment there is no static. It is a clear channel.” — Dr. Sarah

What Is a Subluxation — and How Does It Affect the Whole Body?

Here’s where things get important — and where most people’s understanding of chiropractic stops short.

When the weight of physical, chemical/toxic, and/or mental/emotional stress is heavier than what your nervous system can adapt to, you get subluxated. More often than not, subluxations are silent to our conscious minds, however subconsciously our brain-body is working in overdrive to handle the massive problem known as subluxation. 

When subluxated, the brain immediately recognizes this as a problem of neurological interference and tells the body to release cortisol. Once cortisol is released, then comes inflammation, and from that sometimes comes symptoms of pain, tension, or discomfort, if you’re lucky! You’re lucky because your body has given your conscious mind an opportunity to recognize a problem and do something about it. 

Think of subluxation like static on a radio. The broadcast is still going — your brain is still trying to communicate with your body — but something is scrambling the transmission. The message gets through partially, distorted, or with a delay. A long time of this causes other systems in the body to be drained and depleted.

A subluxation is not just a “back problem.” It is a point of interference in the brain-body communication channel. And because your nervous system doesn’t just serve your muscles and joints — it connects to every organ, every gland, every system in your body — that interference doesn’t stay local. It radiates outward.

The nerves exiting your cervical spine feed into your arms, shoulders, and neck — but also into your sinuses, your thyroid, and your heart. The nerves branching off your thoracic spine connect to your lungs, your diaphragm, your digestive organs. Your lumbar nerves reach your legs, your bladder, your reproductive system. A subluxation at any of these levels creates static in the signal to everything downstream.

This is why people under regular chiropractic care often report improvements that seem to have nothing to do with their spine — better digestion, fewer headaches, improved sleep, more regulated immune response. These aren’t coincidences. They are what happens when you restore clear communication to a nervous system that was running on interference.

This is what I’m looking for every time I examine a patient. Not just where it hurts — but where the interference is.

What Does a Chiropractic Adjustment Actually Do?

When I find a subluxation and adjust it, I am not just “cracking your back.” I am not treating a muscle or manipulating a joint for its own sake. I am removing a point of interference from your nervous system so your brain and your body can communicate clearly again.

Here’s the before and after — and I want you to really hold this image:

Before the adjustment: There is static. There is tension, dysfunction, and miscommunication between your brain and body. Your muscles are braced — not because of a conscious decision, but because your nervous system is under stress and your body is compensating. Your brain is working harder than it should have to, trying to manage a body it can’t fully hear. Your energy is being drained at every moment. 

After the adjustment: The channel is clear. The interference is gone. Your nervous system is free to do its job without fighting through static. Your muscles relax — not just at the surface level, but at the neurological level, because your brain can finally relax too. The tension you’ve been carrying wasn’t just muscular. It was your entire nervous system bracing against interference.

When your brain and body are communicating freely, your body’s innate intelligence takes over. It begins doing what it has always known how to do — regulating, restoring, and healing from within. That is not chiropractic healing you. That is chiropractic removing what was in the way so you could heal yourself.

Different adjustment techniques serve different purposes in this process. Gonstead analysis pinpoints the specific vertebra causing interference with precision. Thompson drop technique uses a segmented table to deliver gentle, targeted corrections. Toggle and upper-cervical work addresses the relationship between the skull and the top of the spine — one of the most neurologically dense areas in the body. Sacro-Occipital Technique (SOT) works with the sacrum, occiput, and the cerebral spinal fluid (CSF) to balance the foundational structure of the entire spine. Each technique is a different way of clearing the same thing: interference in the nervous system.

Why Is Chiropractic About Far More Than Back Pain?

Chiropractic is not a pain treatment.

Pain is a signal. It is your nervous system telling you something needs attention. When chiropractic care helps someone’s pain resolve, that is meaningful — but it is a downstream effect, not the mechanism. The mechanism is nervous system interference being cleared. The pain relief is what happens when the body stops fighting itself.

The nerves branching off your spinal cord don’t just go to your back muscles. They go to your heart. Your lungs. Your stomach. Your immune system. Your hormonal system. Your skin. The neural pathways that carry life-force energy through your body are the same pathways that regulate every function you have — every process that keeps you alive, every adaptation your body makes to stress, sleep, nutrition, and environment.

When those pathways are clear and connected, you have more LIFE moving through you. When they’re under interference, something is always working harder than it should — compensating, bracing, adapting around a signal that isn’t getting through cleanly.

The better sleep, the clearer head, the improved digestion, the more regulated mood — these are not side effects of chiropractic care. They are the direct result of nerve energy flowing the way it was designed to flow. A nervous system free of interference doesn’t just hurt less. It functions better. Across the board.

Is Chiropractic Only for Adults With Back Pain?

Not even close. The nervous system doesn’t discriminate by age or symptom — and neither does the value of keeping it free of interference.

Newborns can experience vertebral stress during delivery. Children’s nervous systems are developing rapidly and deserve a clear foundation. Pregnant women are undergoing extraordinary neurological and structural change — the Webster Technique, which I hold an advanced certification in, addresses the specific pelvic and sacral alignment that supports both the mother’s nervous system and optimal fetal positioning. Athletes push their spines and nervous systems to their limits. People under chronic stress are often running their nervous systems in overdrive for so long they’ve forgotten what it feels like to be regulated.

Chiropractic care isn’t about waiting for something to break down. A clear, interference-free nervous system is what allows your body to meet every demand it faces — physical, emotional, and environmental. You don’t have to wait until something breaks down to take care of your nervous system.

Frequently Asked Questions

What causes a subluxation?

A subluxation — nerve interference that is accompanied by a misalignment of vertebrae — can develop from physical stress like a fall, repetitive posture, or old injury, as well as emotional and chemical stress. Your body often compensates around subluxations quietly, which is why many people don’t feel them until something tips the balance. Regular spinal assessments can catch interference before it compounds.

How does chiropractic help with things that seem unrelated to the spine?

Because your nervous system connects your brain to every organ, gland, and system in your body. Cervical subluxations can disrupt nerve flow to the sinuses, thyroid, and heart. Thoracic subluxations affect the lungs and digestive organs. When the interference is removed, the entire system connected to that pathway functions more clearly.

What is the Webster Technique and who is it for?

Webster Technique is the preferred technique for pre-natal patients. It is a chiropractic analysis and adjustment that reduces nervous system stress, balances pelvic bones, muscles and ligaments, and optimizes the mother’s pelvic function in pregnancy and birth. Webster adjustments by Charleston chiropractors are specific and gentle. A special chiropractic drop table and pregnancy pillow is utilized for comfort of the expecting mom during her adjustment.

How do I know if I have subluxations?

Subluxations are often present without obvious pain. Tension, fatigue, recurring illness, digestive irregularity, or simply feeling “off” can all be signs that the nervous system is working harder than it should be. The most accurate way to assess for subluxations is a thorough spinal examination — which is what every new patient appointment at Cypress Chiropractic & Wellness, a chiropractor in Charleston, begins with.

How often should I get adjusted?

Care frequency depends on what we find in your examination, your health history, and your goals. Someone coming in with acute discomfort will have different needs than someone maintaining an already healthy nervous system. Subluxations accumulate over time, and proactive care — addressing interference before it causes symptoms — is the same philosophy we apply to dental hygiene, exercise, and nutrition.
