Functional Wellness: Key Concepts Explained to Improve Brain Health

Enhance your cognitive function with insights on functional wellness for brain health and strategies to promote better mental clarity.

Unlocking the Brain-Body Connection: How Neurological Health Shapes Your Everyday Wellness

The brain is not a standalone supercomputer that resides within your skull. With its heart, lungs, blood vessels, muscles, joints, nerves, intestines, and immune system, it is the conductor of a living symphony. Within your brain or spinal cord, every single heartbeat, breath, stride, thought, emotion, and immunological reaction starts as an electrical impulse. You feel resilient, energized, and lucid when this conductor is in good health. The entire orchestra becomes out of tune when it becomes inflamed, agitated, misaligned, or chemically imbalanced. This may result in headaches, chronic tiredness, brain fog, shaky muscles, poor sleep, digestive issues, and pain that appears to originate everywhere and nowhere at once.

We will explain in detail how the brain communicates with the rest of the body in the guide that follows, how common environmental factors can subtly disrupt this communication, how neurological disorders create overlapping health risks, and—most importantly—proven non-surgical methods to restore clear communication between your brain and body. In addition to peer-reviewed research and data from major medical institutes, you will get authentic clinical insights from Dr. Alexander Jimenez, DC, APRN, FNP-BC, in El Paso, Texas.

Let’s get started.

The Brain as the Body’s Command Center

Your brain weighs only about three pounds, yet it uses 20–25% of your body’s total energy every day (Cleveland Clinic, 2024a). Inside are roughly 86 billion neurons and an even larger number of support cells called glia. Neurons send lightning-fast electrical signals that travel down the spinal cord and out through peripheral nerves to every corner of the body (Kandel et al., 2021).

The central nervous system (CNS)—brain + spinal cord—acts like the main highway. The peripheral nervous system is the system of on-ramps and off-ramps that reaches your fingertips, toes, heart, stomach, and lungs. Together, they form one continuous communication loop.

Example: You decide to pick up a glass of water.

1. The motor cortex in your brain plans the movement.
2. Signals race down the spinal cord.
3. Motor nerves tell forearm muscles to contract and fingers to curl.
4. Sensory nerves instantly report back how heavy the glass feels and whether it is slipping.
5. Your brain makes micro-adjustments in less than a tenth of a second.

This conversation happens millions of times per day without you thinking about it (Bear et al., 2021).

How the Brain Controls Muscles and Joints

Movement is not just “muscles pulling on bones.” The brain constantly predicts, adjusts, and corrects.

• The cerebellum (the “little brain” at the back) fine-tunes balance and coordination.
• The basal ganglia smooth out motions so you don’t look robotic.
• Proprioceptors (tiny sensors in muscles and joints) send position updates 100 times per second back to the brain.

When spinal misalignments (subluxations) or old injuries block these signals, muscles become weak or spastic, joints ache, and balance suffers (Jimenez, 2023a). Dr. Jimenez has documented hundreds of patients whose chronic knee or shoulder pain disappeared after gentle cervical (neck) adjustments—because the real problem was distorted brain-to-muscle signaling, not the joint itself (Jimenez, 2024a).

The Brain–Nerve–Organ Superhighway (Autonomic Nervous System)

You don’t have to remember to breathe or digest your lunch. That is the job of the autonomic nervous system (ANS), which has two branches:

1. Sympathetic (“fight-or-flight”) – speeds heart, dilates pupils, shuts down digestion.
2. Parasympathetic (“rest-and-digest”) – slows heart, boosts digestion, promotes sleep and healing.

The vagus nerve is the main parasympathetic highway. A good “vagal tone” means your body can relax quickly after experiencing stress. Poor vagal tone is linked to inflammation, anxiety, IBS, and autoimmune diseases (Breit et al., 2018).

Chiropractic adjustments, slow breathing, cold showers, singing, and acupuncture all measurably increase vagal tone within minutes to weeks (Jimenez, 2023b; Gerasimov et al., 2022).

Environmental Factors That Quietly Damage Brain-Body Communication

Modern life is full of hidden neurological stressors:

• Air pollution – ultrafine particles cross the blood-brain barrier and trigger microglial inflammation (Calderón-Garcidueñas et al., 2019).
• Blue light at night – suppresses melatonin by up to 70%, disrupting sleep and vagal tone (Wahl et al., 2019).
• Processed foods high in refined seed oils are associated with increased systemic and brain inflammation (DiNicolantonio & O’Keefe, 2021).
• Chronic psychological stress causes the hippocampus to shrink and the amygdala to enlarge (McEwen, 2017).
• Sedentary behavior reduces brain-derived neurotrophic factor (BDNF), the “fertilizer” for the growth of new neurons (Erickson et al., 2019).
• Electromagnetic fields (EMF) – emerging research shows possible effects on calcium channels in neurons (Panagopoulos et al., 2021).

The result? A brain that is constantly in low-grade “danger mode,” sending erratic signals to muscles (tension), joints (pain), gut (IBS), and immune system (autoimmunity).

Neurological Disorders and Their Overlapping Body-Wide Effects

Many neurological conditions share the same root inflammatory pathways, which explains why patients often have multiple diagnoses at once.

• Concussion/Traumatic Brain Injury (TBI) ? neck misalignment ? vagus nerve irritation ? gut problems + anxiety + headaches (Ellis et al., 2021; Jimenez, 2023c).
• Multiple Sclerosis ? myelin damage ? slow signals ? muscle spasticity + bladder dysfunction + fatigue (Cleveland Clinic, 2024b).
• Parkinson’s ? dopamine loss ? tremor + rigid muscles + constipation + depression (Kalia & Lang, 2015).
• Fibromyalgia ? central sensitization ? widespread pain + sleep disturbance + brain fog (Sluka & Clauw, 2016).
• Peripheral neuropathy ? damaged sensory nerves ? burning feet + balance loss + falls risk (Cleveland Clinic, 2024c).

These are not separate diseases—they are different expressions of disrupted brain-body conversation.

The Most Common Symptoms People Experience When the Conversation Breaks Down

1. Headaches & migraines (tension, cervicogenic, or neuro-inflammatory)
2. Brain fog & poor concentration
3. Chronic fatigue that sleep doesn’t fix
4. Sleep disturbances (trouble falling asleep, staying asleep, or feeling refreshed)
5. Dizziness or vertigo
6. Muscle weakness, tremors, or instability
7. Joint stiffness without arthritis on X-rays
8. Tingling, numbness, or burning pain in arms/legs
9. Digestive issues (bloating, reflux, IBS)
10. Mood swings, anxiety, or feeling “wired but tired”

Dr. Jimenez reports that 8 out of 10 new patients in his clinic check at least six of these boxes—often after being told “everything looks normal” on standard blood work (Jimenez, 2024b).

Non-Surgical Treatments That Actually Restore Brain-Body Communication

Chiropractic Neurology & Spinal Adjustments

Gentle, specific adjustments remove interference at the spine, allowing the brain to receive clean sensory input and send clean motor output. Multiple studies have shown that chiropractic care reduces headache frequency by 50–70% and improves vagal tone (Bryans et al., 2011; Gerasimov et al., 2022).

Functional Neurology Exercises

Eye-tracking drills, balance boards, vestibular therapy, and neuro-sensory integration exercises literally “rewire” damaged pathways after concussion or stroke (Carrick et al., 2017).

Acupuncture & Dry Needling

Stimulates the vagus nerve, increases endorphins, and down-regulates pain centers in the brain. Meta-analyses show excellent results for migraine, neuropathy, and low-back pain (Vickers et al., 2018).

Massage & Myofascial Release

Lowers cortisol, increases oxytocin and serotonin, improves blood flow to the brain, and breaks up adhesions that irritate nerves (Field, 2016).

Physical Therapy & Corrective Exercise

Rebuilds proprioception, strengthens stabilizing muscles, and teaches the brain new movement patterns (Page, 2012).

Nutrition & Lifestyle Medicine

• Omega-3s (EPA/DHA) ? reduce neuroinflammation (Guan et al., 2021).
• Magnesium, B-vitamins, and vitamin D ? support nerve conduction and energy (Calderón-Ospina & Nava-Mesa, 2020).
• Ketogenic or low-glycemic diets ? stabilize blood sugar and reduce brain excitability in epilepsy, migraine, and TBI (Bahr et al., 2020).
• Intermittent fasting ? boosts BDNF and autophagy (Mattson et al., 2018).

Vagus Nerve Stimulation Techniques

Cold showers, gargling, humming, yoga, and specific chiropractic adjustments all increase heart-rate variability (HRV)—the gold-standard marker of healthy vagal tone (Breit et al., 2018).

 Your Body Is Waiting to Heal

Because of injuries, pollutants, stress, and time, your brain and body began speaking different languages, yet they never stopped communicating. The neurological system’s remarkable plasticity is the lovely reality. Your brain is sending out the obvious message, “I’m ready to reconnect,” with each light chiropractic treatment, deep breath, nutritious meal, acupuncture needle, and outside walk.

Surgery and lifetime medication are not necessary to restore your sense of self. You need dependable, astute treatment that honors the human nervous system’s magnificent architecture.

Get started now. Find a functional neurology-trained chiropractor. Include actual food and movement. Like treasure, safeguard your sleep. In just a few short weeks, you may transition from feeling disjointed and shattered to waking up with clarity, strength, and excitement for the day, as your body and brain finally communicate in the same language.

Your purpose was to flourish. Let your nervous system demonstrate it now.
