Seeking Safety from the Inside Out
The Cell Danger Response (CDR), first identified by Dr. Robert Naviaux, is a critical protective mechanism at the cellular level. It’s the body’s built-in emergency system, activated in response to a wide range of threats such as infections, toxins, physical trauma, or chronic emotional stress. Read his research paper here.
The CDR is an adaptive, protective mechanism designed to protect cells from harm, slow down normal functions, and focus resources on survival and repair.
At its core, the CDR is about creating safety. When cells feel threatened, they shift their priorities from growth and maintenance to defense. This is a temporary state that, in an ideal world, allows the body to recover and heal. However, when the body gets stuck in this defensive mode, chronic illness can set in, preventing the cells—and by extension, the entire body—from returning to a state of balance.
Cellular Safety: Mitochondrial Function and Immune Response
Under normal circumstances, mitochondria—the powerhouses of our cells—efficiently generate energy in the form of ATP, ensuring that cells function smoothly and maintain overall health. But when the body senses danger, such as an infection, toxin, or injury, it activates the Cell Danger Response (CDR). This response is an adaptive, protective mechanism where mitochondria temporarily shift to a less efficient energy pathway called glycolysis. By doing this, the body limits oxidative stress and cellular damage while directing resources to essential survival functions.
This shift is initially beneficial and a key part of the healing process. It’s like putting the body into a defensive stance—redirecting its energy from routine activities to focus on dealing with the immediate threat. Meanwhile, the immune system gears up, releasing signals that activate immune cells to combat the threat and repair damaged tissues. This coordinated effort helps clear out invaders and support tissue regeneration.
However, problems arise when this adaptive response lingers. The CDR is designed to be temporary, but in chronic conditions like PANS/PANDAS, chronic fatigue syndrome, fibromyalgia, Lyme disease, and mold toxicity, the body continues to perceive threats long after the initial danger has passed. The CDR remains stuck in this heightened state, causing the mitochondria to stay in this less efficient energy mode. Over time, this leads to mitochondrial dysfunction, reduced energy production, and a buildup of byproducts that contribute to oxidative stress and inflammation.
The Role of the Sympathetic and Parasympathetic Nervous Systems
When the body perceives danger, it doesn’t just shift at the cellular level—it also activates the sympathetic nervous system, the part of the autonomic nervous system responsible for our “fight or flight” response. This system is what kicks in when you feel your heart race, your breathing quicken, or your muscles tense up in response to stress or a threat. It’s the body’s way of preparing for action, focusing all resources on immediate survival.
But for the body to recover and heal, it needs to return to a state of rest and repair, which is managed by the parasympathetic nervous system—often called the “rest and digest” system. The parasympathetic system helps us unwind and recover, slowing the heart rate, promoting deep breathing, and stimulating digestion. It’s the body’s natural way of restoring balance after the threat has passed.
In chronic conditions, however, the sympathetic system often stays activated, and the body remains on high alert. This prolonged state of vigilance not only prevents healing but can also exacerbate inflammation, impair digestion, and contribute to ongoing symptoms like fatigue and anxiety. Understanding the balance between the fight-or-flight response and the rest-and-digest state is crucial for addressing chronic illness and restoring the body’s natural rhythms.
Chronic Activation of the Immune System
In a similar way, the immune system, which initially ramps up to fight off threats, becomes maladaptive when it stays on high alert. This prolonged immune activation can lead to chronic inflammation and, in some cases, autoimmune reactions, where the body mistakenly attacks its own healthy tissues. What began as a necessary response to a short-term threat turns into an ongoing assault that disrupts normal cellular and immune function.
This chronic, stuck CDR creates a cycle where the body struggles to heal, perceiving normal stimuli as threats and continuously directing energy away from vital functions. This not only impacts physical health but can also contribute to symptoms like brain fog, mood disturbances, and persistent fatigue.
The Limbic System and Vagus Nerve: The Emotional and Physical Guardians of Safety
At a larger scale, creating a sense of safety isn’t just about cellular function—it’s about how the entire body perceives and responds to stress. Two critical systems—the limbic system and the vagus nerve—are deeply involved in how the body manages stress and recovers from chronic illness. Both need to be addressed to fully resolve the chronic activation of the CDR.

Vagus Nerve: The Key to Recovery and Resilience
The vagus nerve is the longest and most complex nerve in the body, stretching from the brainstem down through the neck and branching out to connect with vital organs like the heart, lungs, and digestive system. It’s often referred to as the “wandering nerve” because of its extensive reach, touching nearly every major organ and playing a central role in our body’s ability to find balance and maintain health.
As the primary nerve of the parasympathetic nervous system—often called the “rest and digest” system—the vagus nerve acts as a bridge between the brain and the body, continuously sending and receiving signals that regulate critical bodily functions. Unlike the sympathetic nervous system, which triggers the body’s fight-or-flight response in times of stress or danger, the parasympathetic system works to restore calm, promote digestion, and facilitate recovery.
When the vagus nerve is functioning well, it helps regulate the body’s stress response, ensuring that we’re not stuck in a constant state of heightened alertness. It helps slow the heart rate, promotes deep, relaxed breathing, and stimulates digestive processes, which are essential for absorbing nutrients and maintaining gut health. But the benefits of a healthy vagus nerve don’t stop there—it also plays a crucial role in regulating inflammation.
Vagus Nerve and Inflammation
The vagus nerve acts as a communication highway, sending signals from the brain to the immune system to help regulate inflammation. It does this through what’s known as the “inflammatory reflex.” When inflammation levels rise due to injury or infection, the vagus nerve senses these changes and sends signals to the body to modulate the inflammatory response, preventing it from becoming excessive or chronic. This keeps the immune system balanced and prevents an overreaction that could harm the body’s own tissues.
By calming the nervous system and regulating inflammation, the vagus nerve supports homeostasis, the body’s natural state of balance. Homeostasis is essential for long-term health, as it ensures that all systems are working in harmony to maintain stability, repair damage, and adapt to change.
Vagus Nerve Dysfunction and Health
When the vagus nerve is not functioning optimally, the body can lose its ability to regulate stress and inflammation effectively. This can lead to chronic issues such as persistent inflammation, digestive problems, heart rate irregularities, anxiety, and depression. Given its extensive connections, vagus nerve dysfunction can contribute to a wide range of health challenges, from gastrointestinal issues to autoimmune conditions.
Practices like deep breathing, meditation, yoga, cold exposure, and even humming have been shown to stimulate and strengthen vagus nerve function, helping to restore a sense of calm and balance to the body. It reminds us that healing is not just about treating individual symptoms, but also about restoring harmony within the body’s interconnected systems.

Chronic Illness and CDR: Why Retraining the Limbic and Vagus Systems Is Key
In chronic conditions like PANS/PANDAS, Lyme disease, or mold toxicity, the body is often stuck in a loop of perceived threats. The CDR remains activated, preventing recovery and creating a cascade of symptoms—from fatigue and anxiety to neuroinflammation and cognitive dysfunction. Healing in these conditions requires addressing both the emotional and physical aspects of safety.
- Limbic retraining helps calm the brain’s emotional reactivity, signaling that the environment is safe.
- Vagus nerve stimulation restores balance to the body’s autonomic nervous system, encouraging physical recovery and reducing chronic inflammation.
Both systems must work in harmony to fully deactivate the CDR and allow the body to shift from defense into repair.
Tools to Restore Cellular and Systemic Safety
Addressing chronic CDR requires a comprehensive approach that supports both cellular health and nervous system regulation. Here are some effective strategies:
- Nutritional and Herbal Support: Supplements that enhance mitochondrial function and reduce oxidative stress, like omega-3 fatty acids, CoQ10, and antioxidants (e.g., vitamins C and E), can be powerful allies in calming the CDR and supporting energy production.
- Detoxification and Environmental Controls: Reducing toxic exposures is essential to breaking the cycle of chronic CDR. Supporting natural detox pathways through hydration, proper nutrition, and herbs like milk thistle and chlorella can help the body eliminate stored toxins.
- Limbic System Retraining: Programs like the Gupta Program, Dynamic Neural Retraining System (DNRS) or Primal Trust can help rewire the brain’s response to chronic stress and perceived threats.
- Vagus Nerve Stimulation: Practices like deep breathing, cold exposure, and biofeedback can improve vagal tone, enhance HRV, and promote a state of calm, supporting the body’s recovery process.
- Mindfulness and Meditation: Incorporating daily practices like meditation and mindfulness can reduce stress and retrain both the limbic system and the vagus nerve, helping the body feel safe and supported at every level.
The Journey Toward Healing: Safety at Every Level
Healing from chronic illness, especially with conditions like PANS/PANDAS, requires creating safety at every level—starting from the cells and extending all the way to the nervous system and emotional well-being. By calming the limbic system and enhancing vagal tone, we can signal to the body that it is no longer under threat, allowing it to step out of defense mode and into healing. When safety is restored physically, emotionally, and even at the cellular level the body can finally shift from survival to true recovery.
