CIRS, Developmental Trauma, and Nervous System Dysregulation
If you have been diagnosed with CIRS, you are likely to benefit from learning how to regulate your nervous system.
If you haven’t already charged down the path, I encourage you to pause before spending large sums of money chasing medical solutions or remediating mould without fully understanding what your body needs to heal. It is not uncommon for people to spend tens of thousands of dollars annually on medical care and home remediation. For many, neither approach is sufficient on its own until nervous system dysregulation is also addressed.
Slow down, educate yourself, and then make a plan.

You may hear statistics suggesting that a significant proportion of buildings have some degree of water damage. Mould exposure can occur in many ordinary environments: workplaces, gyms, arenas, gardens, or during travel in humid climates. The question is not whether mould exists in the world—it does—but why some people become ill while many others do not.
Please don’t rush to spend your hard-earned money. Take time—weeks or even months if needed—to understand what will truly support your recovery.
Why vulnerability matters.
If you have been diagnosed with CIRS, there is a reasonable possibility that you also have a history of developmental trauma. You may find it helpful to complete the ACEs (Adverse Childhood Experiences) questionnaire, which is widely available online. Research consistently shows that higher ACE scores are associated with increased risk for health problems later in life, including conditions such as chronic inflammatory illness, chronic fatigue, fibromyalgia, mast cell activation, autoimmune disorders, and Lyme disease.
The common thread is nervous system dysregulation. Nervous system dysregulation can be described in many ways. You might say you have difficulty staying calm, that you are easily triggered, or that you struggle to maintain balance and stability. In more technical language, you may hear references to difficulty remaining in a ventral vagal state or maintaining homeostasis. In plain terms, your nervous system is rarely at rest.
The mechanism is relatively straightforward. When a child grows up in a chronically stressful or unsafe environment, their body adapts by remaining on high alert. Stress hormones such as cortisol and adrenaline become elevated more often than they should. Over time, this heightened baseline does not settle back down on its own. Without intentional and sustained effort, the nervous system remains primed for danger.

Fear and Its Role in Ongoing Illness
Fear as a chronic background state.
Mental health professionals often use the term anxiety to describe nervous system dysregulation. I prefer the word fear because it more accurately reflects the lived experience. When you were told you had CIRS, fear was likely your first reaction.
Long before receiving a diagnosis—and certainly afterward—you may have found yourself worrying about your health, your future, and your environment. You may feel afraid of everyday activities: breathing fumes at a gas station, drinking from disposable cups, eating at restaurants, or walking barefoot on grass. Fear can quietly take over daily life.
Awareness is the first step. I encourage you to focus less on determining whether every situation is objectively safe and more on noticing your fear itself. It is also worth asking why you became ill following exposure when many people around you did not.
Why fear often goes unaddressed.
Functional medicine physicians and naturopathic doctors appropriately focus on physical contributors to illness. What is often missing is direct attention to fear and nervous system regulation.
An analogy may help. If people are frequently drowning at one section of a river, emergency responders may be stationed there to pull them out. While lifesaving, this does not address why people are falling into the river upstream. Without investigating the source, the problem continues.
How fear influences recovery.
This does not mean fear is the sole cause of illness, but rather that it can meaningfully influence how the body responds to stress, exposure, and recovery.
In this analogy, medical interventions are the emergency responders. They are necessary, but incomplete. What pushes people into the river is often a long history of developmental trauma and chronic nervous system dysregulation.
Clinical examples.
I worked with a client whose husband had been diagnosed with CIRS. His fear was so overwhelming that he was unable to research or coordinate his own care. His partner took on the burden while he remained immobilized by fear.
I also worked with a client who was ordered to return to work before she was physically ready. Rather than challenge the decision, she complied out of fear. Her health deteriorated rapidly after she had been making progress.
A third client, an accomplished professional with a significant trauma history, experienced clear declines in physical health during periods of heightened fear.

Supporting Recovery Through Regulation
Recognizing and documenting fear.
The first step toward recovery is recognizing fear. Several times a day, pause and ask yourself what you are afraid of in that moment.
Journaling can help you see patterns. You might ask yourself:
- Am I afraid right now?
- What am I afraid of?
- How much of the day do I feel afraid?
- When do I feel calm, if at all?
- What situations reliably dysregulate me?
Some concerns are reasonable. The problem arises when fear itself becomes a chronic driver of physiological stress.
Regulation as a foundation for healing.
Once you see your fear clearly, acknowledge that awareness as progress. From there, you can begin learning how to regulate your nervous system. As regulation improves, the body is better able to heal.
Meditation is one effective tool. Start with ten minutes if longer periods feel inaccessible. With practice, many people notice that self-regulation becomes more available between sessions.
You do not need to process every aspect of your childhood trauma to recover. What is essential is learning to reduce the constant fear that keeps your nervous system dysregulated.
Addressing ongoing stressors.
As you work toward regulation, you may also need to address ongoing stressors such as difficult relationships or workplace pressures that perpetuate fear.
Recovery is possible.
I have known people who made a full recovery from CIRS—even after many years of illness—by addressing fear and nervous system dysregulation alongside medical care.
Considering Next Steps
If you have recently been diagnosed with CIRS, this is not the time to rush or to make fear-driven decisions. Slowing down is not avoidance—it is often a necessary part of recovery.
Begin by paying attention to your nervous system. Simple practices that support regulation—such as meditation, paced breathing, gentle movement, and reducing unnecessary stimulation—can help create the internal conditions your body needs to heal.
Medical care can be an important part of treatment, but it is rarely sufficient on its own when nervous system dysregulation is driving symptoms. Working with a psychologist who understands trauma and chronic stress can help you regain stability.
If you are early in this process, give yourself time to learn, reflect, and make informed decisions.
I wish you well in your recovery.
