In the movie 8 Mile, there is a visceral scene where Eminem’s character, B-Rabbit, stands over a bathroom sink and vomits right before a high-stakes rap battle. We usually just call that "nerves," but it is actually a perfect look at a biological survival mechanism. In that moment, his body wasn’t just anxious. It was literally fighting for its life.
Most of us aren’t stepping into a rap battle today, but our bodies are often locked in that same gut-wrenching state. Between "tech neck" and sitting at a desk for eight hours a day, we are constantly signaling to our brains that we are under threat. To find our way back to health, we have to understand that our nervous system is like a biological seesaw, and most of us are stuck on the wrong side.

The "Biological Seesaw" of Your Internal Wiring
Your health is driven by the Autonomic Nervous System (ANS). It is divided into two primary branches: the Sympathetic (fight or flight) and the Parasympathetic (rest and digest).
These two systems have a strict inverse relationship. When one is up, the other must be down. They cannot both dominate at the same time. If your body perceives a threat, whether it is a work deadline or a physical misalignment in your spine, your "fight or flight" response takes over. You cannot simply think your way into relaxation if your body feels physically threatened.
The Energy Budget: Why Your Body Sacrifices Digestion
When your sympathetic nervous system is stuck in high gear, your body starts making cold calculations regarding your energy budget. In a crisis, survival is the only priority. Your body does not care about long-term maintenance; it only cares about surviving the next five minutes.
This is exactly why B-Rabbit vomits. Your body is purging or halting digestion to move every available calorie to your muscles and your heart. As we often tell patients, your body is simply trying to survive, so it does not want to use the energy it has to digest food. If you are chronically stressed, you are effectively starving your digestive and reproductive systems of the energy they need to thrive.
The "Flexion" Trap: When Your Body Hides from the World
The most important link between your spine and your stress level lies in a concept called subluxation. When a vertebra becomes misaligned, it puts direct pressure on a nerve. In an act of biological intelligence, your body attempts to protect that nerve by pulling itself into flexion.
Flexion is the act of slumping, rounding the shoulders, and collapsing the chest. It is essentially a standing fetal position. It is an instinctual move of protection designed to shield your vital organs. However, in our modern lifestyle, we spend all day in this slumped position at our computers. By remaining in this flexed stance, we are trapped in a feedback loop. Your body puts you in flexion to take pressure off a nerve, but that very posture signals to your brain that you are in a state of fear. You aren't just sitting poorly; you are physically manifesting a permanent fear response.
The Chemical Hijack: How Cortisol Kills Your Joy
This physical state of protection comes with a devastating chemical price tag. When the sympathetic nervous system is dominant, your body floods with cortisol. While necessary for short-term survival, chronic cortisol acts as a chemical hijacker.
High levels of cortisol do not just make you feel edgy. They actively kill off your body's production of happy hormones. Specifically, cortisol suppresses:
- Serotonin: Your primary mood stabilizer and happiness chemical.
- Melatonin: The essential hormone for deep, restorative sleep.
- Dopamine: The chemical driver for reward, motivation, and focus.
This is why you cannot simply supplement your way out of a bad mood or a sleepless night. If your spine is stuck in a state of flexion, your brain will continue to pump out cortisol, effectively neutralizing any serotonin or melatonin you try to produce.
The Chiropractic Adjustment as a Nervous System "Reset"
This is where the role of the chiropractor becomes essential. A chiropractic adjustment isn't just a back rub. It is a targeted intervention to remove the subluxation and release the pressure on the nerve.
Once that pressure is removed, the body no longer feels the need to hide in a protective flexion position. It is finally allowed to return to a neutral, upright stance. This physical shift stops the constant stimulation of the fight or flight response. The seesaw finally tips back.
The result is a systemic reset that allows the body to move into the rest and digest phase. The clinical results are often immediate and profound:
- Rest: Sleep quality improves as melatonin production resumes.
- Mood: Emotional stability returns as serotonin levels stabilize.
- Focus: In children with ADD or ADHD, focus often improves dramatically because their brains are no longer trapped in a sympathetic drive.
Beyond the Back Rub
True wellness is the bridge between the physical and the chemical. Your spinal alignment is the thermostat for your nervous system. If it is set to protection mode, your body will continue to burn through its energy budget while killing off the hormones you need for a happy, restful life.
By correcting the physical misalignments that keep us slumped and stressed, we can finally stop fighting for survival and start living in a state of growth.
Is your body currently fighting for its life, or is it finally being allowed to rest and digest?
