How the Nervous System Affects Your Child’s Immune Health: Natural Pediatric Solutions in San Diego
If your child struggles with chronic illnesses, recurring infections, allergies, gut issues, or immune system challenges tied to conditions like autism spectrum disorder (ASD), you’re not alone.
Many San Diego parents feel like they’ve tried everything—yet their child’s health still isn’t where it should be.
What if the missing piece isn’t just about boosting the immune system… but about supporting how your child’s brain and body communicate?
At Sprout Family Chiropractic in San Diego, we take a different, neurological approach to pediatric wellness. We look at your child’s immune function through the lens of the nervous system—because the two are deeply connected.
In this blog, you’ll learn how the nervous and immune systems work together, how chronic stress and dysregulation can affect your child’s health, and how drug-free options like chiropractic care and low-level laser therapy can help restore balance—naturally.
How Your Child’s Nervous System Impacts Their Immune Health
At Sprout Family Chiropractic in San Diego, we focus on one of the most overlooked aspects of your child’s health: their nervous system.
Think of it as the body’s master control center.
The nervous system includes the brain, spinal cord, and an intricate web of nerves that send and receive messages. It processes everything your child experiences—from sounds and sights to emotions and immune responses—and sends signals to every organ, tissue, and cell in the body.
It controls movement, learning, digestion, breathing, immune regulation, and even healing.
In kids, this system is still developing and is highly sensitive to stressors like birth trauma, chronic illness, inflammation, or toxic overload. When the nervous system is overwhelmed, it can’t properly guide the systems it manages—especially the immune system.
How does the nervous system impact the immune system? And what happens when this neuroimmune system is dysregulated?
What Is the Autonomic Nervous System? (And How It Impacts Chronic Illness in Kids)
Your child’s autonomic nervous system (ANS) oversees all the automatic functions in their body—like heartbeat, digestion, and yes, even how they fight off infections or heal from illness.
It has three main branches that each impact immune health:
Sympathetic Nervous System (SNS): Known as the “fight or flight” system, it prepares the body for danger. But when kids are constantly in stress mode (like many with sensory or developmental challenges), this system stays “on,” leading to frequent illnesses, poor digestion, chronic inflammation, and overactive immune responses like allergies or eczema.
Parasympathetic Nervous System (PNS): This is the “rest and digest” branch—and the one responsible for healing and immune recovery. One of its key components is the vagus nerve, which helps calm inflammation and regulate immune activity. When balanced, kids often sleep better, digest better, and get sick less often.
Enteric Nervous System (ENS): Often called the “second brain,” this network lives in the gut and directly communicates with both the brain and immune system. It plays a huge role in the gut-brain-immune connection. That’s why kids with immune issues often also have digestive problems like constipation, food sensitivities, or bloating.
If your child is struggling with immune issues, frequent illness, or developmental challenges, we’re here to help. Book an initial pediatric chiropractic appointment with Dr. Nicole Wong-Homer and Dr. Rachel Wong-Homer at Sprout Family Chiropractic in San Diego to see how nervous system-focused care can support their immune health, naturally.
Why Your Child’s Immune System Is Always Struggling: Root Causes You May Be Missing
Your child’s immune system is their built-in defense team. It’s designed to protect against viruses, bacteria, and anything that doesn’t belong—while also helping the body heal and recover.
But the immune system does much more than just fight germs. It plays a key role in:
Regulating inflammation
Repairing tissues after illness or injury
Clearing out damaged or abnormal cells
Communicating with the brain and nervous system
Supporting gut health and detoxification
When working well, the immune system knows when to activate and when to rest. But if your child is constantly getting sick, dealing with allergies, or healing slowly, it may be a sign that their immune regulation is out of balance.
At Sprout Family Chiropractic in San Diego, we often see this in kids with chronic illness, frequent infections, or conditions like autism spectrum disorder (ASD)—where the immune system is working too hard, not hard enough, or simply confused.
The Nervous System and Immune System Connection in Kids
The nervous system and immune system are in constant communication—a relationship sometimes referred to as the neuroimmune connection.
Here’s how they talk to each other:
Immune cells use chemical messengers (called cytokines) to alert the brain when something’s wrong—like an infection or injury. These signals can also impact your child’s mood, behavior, and sleep.
Nerves, especially those in the autonomic nervous system, send messages to immune cells using neurotransmitters like norepinephrine and acetylcholine. These help turn the immune response up or down, depending on what the body needs.
The vagus nerve—a major player in the parasympathetic nervous system—can calm inflammation by signaling immune cells to stand down once the threat has passed.
So, when your child is sick, their immune system tells the brain to slow down: they feel tired, lose their appetite, and need rest. But when your child is stressed, the brain can tell the immune system to hold back—making it harder for their body to recover.
That’s why a dysregulated nervous system often leads to a weakened immune response, chronic inflammation, or slow healing.
Neuroimmune Dysregulation in Children: What It Is and Why It Matters
“Why is my child’s immune system weak?”
When your child’s nervous system becomes overwhelmed—whether from chronic stress, birth trauma, toxin exposure, or developmental challenges—it can’t properly regulate the immune system. This breakdown in communication, known as neuroimmune dysregulation, can lead to a range of chronic health concerns in children.
Common signs your child’s neuroimmune system may be out of balance include:
Frequent illnesses: Your child catches every cold or virus and takes longer to recover than other kids.
Overactive immune responses: Allergies, eczema, or asthma may appear as the immune system starts reacting to harmless things.
Underactive immunity: The body struggles to defend itself, leading to lingering infections and slow wound healing.
Digestive issues: Because 70% of the immune system lives in the gut, stress to the nervous system can cause inflammation, food sensitivities, constipation, or bloating.
Chronic inflammation: The body stays stuck in “fight or flight” mode and can’t fully heal, contributing to fatigue, mood swings, or chronic pain.
Neurodevelopmental challenges: In kids with autism, ADHD, or sensory processing issues, a constantly stressed neuroimmune system can worsen behavior, sleep, focus, and gut health.
“Mystery Symptoms” in Kids That May Be Nervous System Related
When the nervous system and immune system aren’t in sync, symptoms often appear in ways that don’t follow a typical medical pattern—especially if you’re only looking at isolated systems.
These can include:
Difficulty sleeping or staying asleep
Sensitivity to light, noise, or touch
Persistent fatigue or low energy
Digestive issues (like bloating, reflux, or constipation)
Mood changes, emotional outbursts, or brain fog
Chronic pain or discomfort with no clear injury
For many families, these “mystery symptoms” are deeply frustrating. You’re told your child is fine—yet you know something is off.
What’s likely happening is a breakdown in the neuroimmune-endocrine system—the communication network between your child’s nervous system, immune system, and hormonal regulation. When this system is stressed, symptoms can show up in many different areas of the body, and conventional treatments often don’t get to the root cause.
If your child has dealt with frequent illness, allergies, gut issues, or unexplained symptoms—it’s time to look deeper. Schedule an evaluation at Sprout Family Chiropractic in San Diego to uncover the root causes and get drug-free, nervous system-focused support to help your child heal from the inside out.
How Stress Affects Your Child’s Immune System and Healing
Your child’s sympathetic nervous system is built to protect them. It’s the part of the nervous system that controls the “fight or flight” response—designed to kick in when they’re in danger.
But here’s the problem: many kids today live in a state of chronic nervous system stress. Their bodies are stuck in high alert, even when no real danger is present. This constant overdrive can take a serious toll on their immune function and overall well-being.
When the stress response is always “on,” it can:
Suppress immune function, making it harder to fight off infections
Trigger chronic inflammation, contributing to symptoms like allergies, eczema, or pain
Disrupt gut health, where much of the immune system lives
Delay healing, especially after illness, injury, or surgery
Interfere with sleep, which is critical for growth and immune recovery
Lead to frequent illness, recurring infections, or lingering symptoms
Think of it like a car engine left running at full speed all day. Eventually, parts start to wear down. The same thing happens when your child’s nervous system doesn’t get a chance to rest. It can no longer coordinate the body’s healing processes, and symptoms start to pile up.
Common questions parents ask are, “Why is my kid always sick?” “Why does my kid get sick more often than other kids?” and “How come my kid stays sick for so long?”
How to Calm Your Child’s Nervous System for Better Immune Function
One of the most powerful ways to support your child’s immune system is by helping their nervous system return to a calm, balanced state.
When the body is no longer stuck in fight-or-flight mode, it can begin to repair, recover, and build true resilience. At Sprout Family Chiropractic in San Diego, this is exactly what we focus on through drug-free, neurologically-based care.
Here’s how calming the nervous system helps your child’s immune system thrive:
Balancing the stress response: When we reduce sympathetic nervous system overdrive, the body can stop sounding the alarm—and the immune system can get back to doing its job effectively.
Activating the vagus nerve: The vagus nerve acts like a built-in brake pedal, helping to calm inflammation and support digestion. Stimulating this nerve can help regulate immune activity and create more calm in your child’s system.
Improving sleep: Restful sleep is when the immune system resets, repairs, and strengthens. A regulated nervous system promotes healthy sleep cycles—especially important for children with chronic health issues.
Supporting gut health: Because most of the immune system is housed in the gut, a calm nervous system supports healthy digestion and the gut-brain-immune connection.
Enhancing healing and recovery: When the nervous system is no longer stuck in survival mode, the body can finally shift its focus to long-term healing, growth, and regulation.
At Sprout Family Chiropractic, we use gentle pediatric chiropractic adjustments to reduce stress in the nervous system, improve brain-body communication, and create the internal environment needed for healing to occur—naturally and effectively.
What We See in Our San Diego Pediatric Chiropractic Patients
When your child’s nervous system and immune system begin working together—rather than against each other—the results can be life-changing. At Sprout Family Chiropractic, we’ve seen firsthand how supporting the nervous system helps unlock powerful changes in a child’s health and resilience.
Here are just a few of the common improvements parents report:
Fewer colds and infections: Kids with a well-regulated nervous system tend to get sick less often—and bounce back faster when they do.
Reduced allergies and sensitivities: Nervous system stress can amplify allergic responses. Calming that stress often helps ease symptoms of seasonal allergies, eczema, and asthma.
Better digestion: Through the gut-brain-immune axis, restoring nervous system balance can reduce gut inflammation and improve issues like constipation, bloating, or reflux.
Improved sleep: Nervous system overload often disrupts sleep. Adjustments that support neuroimmune balance can help your child fall asleep more easily and stay asleep longer.
Faster recovery and healing: Whether your child is recovering from illness, injury, or developmental regression, a calm and supported nervous system helps the immune system focus on repair—without interference.
If you’re looking for drug-free, root-cause support for your child’s chronic health concerns, schedule your child’s initial appointment today. Our approach combines gentle pediatric chiropractic care with evidence-informed strategies to support both immune and neurological function—naturally.
How Laser Therapy Boosts the Immune System and Calms the Brain
In addition to chiropractic care, we offer Low-Level Laser Therapy (LLLT)—also known as photobiomodulation—as a gentle, non-invasive way to support your child’s nervous system and immune health.
Unlike medications that suppress symptoms, laser therapy works at the cellular level to restore balance, reduce inflammation, and improve the body’s ability to heal from within.
How does low-level laser therapy at Sprout Family Chiropractic in San Diego help the immune system in kids?
Here’s how LLLT helps kids with chronic illness or immune challenges:
Boosts cellular energy: Laser light stimulates mitochondria (the cell’s energy factories), giving immune cells more energy to respond and repair efficiently.
Reduces inflammation: LLLT helps calm overactive immune responses—ideal for children with asthma, eczema, or frequent infections.
Improves nervous system communication: It supports better signaling through the vagus nerve and brainstem, which helps regulate both stress and immune activity.
Supports gut health: Since much of the immune system lives in the gut, LLLT helps reduce gut inflammation and balance the microbiome—key for kids with digestive or immune-related issues.
Accelerates healing and recovery: Whether your child is recovering from chronic illness, injury, or neurological stress, laser therapy helps speed up repair and reduce lingering symptoms.
This therapy is painless, safe, and well-tolerated by children even with sensory processing or ASD — many don’t even notice it’s being used.
Not All Laser Therapy Is the Same: What Parents Should Know
Not at all. The success of pediatric laser therapy depends on:
Wavelength (color and depth of light)
Dosage (amount of light delivered)
Frequency (how often and for how long)
Application techniques tailored to your child’s specific nervous system needs
At Sprout Family Chiropractic in San Diego, we use FDA-cleared, child-friendly laser devices with protocols developed specifically for kids with immune, gut, or neurological challenges.
Laser therapy is never a one-size-fits-all solution—it’s a powerful tool we customize for your child, often in combination with chiropractic care, to restore regulation from the inside out.
Immune System Red Flags in Children: When to Seek Help
How do you know if your child’s immune system is working as it should?
Often, the body gives subtle clues long before an official diagnosis is ever made. At Sprout Family Chiropractic, we help parents spot those early signs—so you can take action before things spiral into chronic illness or developmental challenges.
Common childhood health problems pediatric chiropractors see when the nervous sytem is dysregulated.
Watch for these red flags that your child may need nervous system and immune support:
Frequent or lingering infections: If your child catches every cold or virus going around—and takes longer than expected to bounce back—it could be a sign their immune system is struggling.
Seasonal allergies or food sensitivities: An overactive immune system can start reacting to harmless things like pollen, pet dander, or certain foods.
Eczema or asthma: These conditions often signal chronic immune stress and inflammation, which can be regulated by calming the nervous system.
Digestive issues: Constipation, diarrhea, bloating, or tummy aches are common in kids with gut-immune imbalances—especially when the nervous system is out of sync.
Sleep troubles: Trouble falling or staying asleep may reflect nervous system stress, which directly impacts immune repair.
Fatigue, behavior shifts, or poor focus: These “mystery” symptoms often show up when the neuroimmune system is out of balance—even in kids without a formal diagnosis.
Developmental regression after illness or fever: Losing milestones or experiencing setbacks in speech, motor skills, or behavior after being sick could point to neuroimmune dysregulation.
Chronic inflammation or delayed healing: If small injuries take a long time to heal or inflammation seems constant, the body may be stuck in a stress response.
If these symptoms feel familiar, your child may benefit from a neuroimmune evaluation at our San Diego office. We combine gentle pediatric chiropractic care, low-level laser therapy, and nervous system scans to uncover the root of the issue—and create a natural care plan that supports healing from the inside out.

FAQs About Natural Immune and Nervous System Care for Kids
1. Does my child need to be sick to benefit from chiropractic care?
No. Chiropractic care isn’t just for pain or illness — it helps optimize nervous system function, which supports immune regulation, digestion, sleep, and emotional balance. Many families use it proactively to support their child’s development and resilience.
2. Can chiropractic adjustments really affect the immune system?
Yes. By calming stress in the nervous system and improving communication between the brain and immune organs, chiropractic care helps the body regulate inflammation, fight off illness, and recover more efficiently.
3. Is chiropractic care safe for babies and children?
Yes. Pediatric chiropractic adjustments are extremely gentle, using light touch or fingertip pressure. At Sprout Family Chiropractic, holistic pediatric care is always customized to your child’s age, size, and nervous system needs.
4. What is low-level laser therapy (LLLT), and how does it help?
LLLT uses specific wavelengths of light to energize cells, reduce inflammation, and promote healing. It’s completely non-invasive and well-tolerated by children. It helps regulate both nervous system stress and immune function — making it a powerful tool for kids with chronic illness, developmental delays, or frequent infections.
5. Will my child feel the laser? Is it safe?
No, most kids don’t feel anything at all! LLLT is painless, safe, and FDA-cleared for children. It doesn’t generate heat and works at the cellular level to support healing and balance.
6. How does the nervous system affect the immune system?
The nervous system and immune system are in constant communication. When the nervous system is stressed or dysregulated (often from chronic stress, inflammation, or trauma), it can confuse the immune system — leading to allergies, frequent illness, poor healing, or even autoimmune responses.
7. What conditions do you most often see improve with chiropractic and laser care?
We often see improvements in:
Recurrent infections or poor immune resilience
Allergies, asthma, or eczema
Digestive issues like constipation or reflux
Sleep challenges
Focus, mood, and emotional regulation
Symptoms related to autism (ASD), ADHD, and sensory processing
What are the benefits of seeing a pediatric chiropractor in San Diego?
8. How long does it take to see changes?
Every child is different. Some families notice improvements within a few visits, especially with sleep or digestion. Others may need more time if the nervous system has been stressed for a while. Our goal is long-term regulation — not just short-term symptom relief.
9. Do you treat autism, ADHD, or immune disorders?
We don’t treat conditions — we support the body. By improving how the nervous system communicates with the immune system, many children with developmental or immune challenges experience meaningful improvements in their health, behavior, and quality of life.
10. How do I know if my child’s nervous system is out of balance?
Common signs include:
Frequent colds or infections
Chronic inflammation or allergies
Sensory sensitivities or meltdowns
Sleep troubles or fatigue
Digestive issues
“Mystery” symptoms that haven’t responded to other treatments
A nervous system evaluation in our office can help identify areas of stress and guide the right care plan for your child.
