View transcript on Buzzsprout

Understanding what the nervous system is and how it works is one thing. The question that tends to feel more urgent is: why won’t it regulate? Why, even when life looks fine from the outside, does the system stay stuck in anxiety or shutdown? Why does knowing better not translate into feeling better?

This is Part 3 of the Back to Basics series, and it focuses on the two primary reasons people get stuck in dysregulation. One is environmental and physiological: the conditions of daily life are working against the nervous system. The other is perceptual: the nervous system has learned to read the world through a lens that no longer reflects reality. Both matter, and both are workable.

What We Cover in This Episode

• Why too many stressors and too few supporters keeps the nervous system stuck in survival mode
• How a hypersensitive nervous system misreads safety as threat
• What protective parts are, where they come from, and how they influence perception and behavior
• Why regulation can feel unfamiliar and even uncomfortable at first

Reason One: The Conditions of Your Life Are Biologically Abnormal

The first reason people get stuck in dysregulation is not a psychological problem. It’s a conditions problem. When there is a significant imbalance between what stresses your nervous system and what supports it, your system will respond with activation or shutdown. That is not a malfunction. That is exactly how a healthy nervous system works.

Consider a plant that starts to wither. It’s not a disordered plant. It’s a plant that isn’t receiving what it needs. When a biological system doesn’t get adequate light, water, and nutrients, it fails to thrive. Human nervous systems work the same way. When the inputs that support regulation are missing or severely depleted, the natural result is anxiety or depression.

Stressors that fill the bucket can include poor or insufficient sleep, inadequate nourishment, blood sugar instability, micronutrient deficiencies, hormone imbalances, chronic stress, unprocessed past experiences, unsafe or depleting relationships, and constant sensory overwhelm. Supporters that need to offset them include sleep, movement, nourishment, regulation practice, connection, and genuine rest.

Many people living with anxiety or depression have spent years receiving diagnoses and prescriptions without anyone asking the most basic questions: How are you sleeping? Are you eating enough? How supported do you feel? What does your daily life actually look like? Being labeled disordered for having a completely natural response to a depleting and overwhelming life is one of the most common experiences our clients describe. It adds shame to an already heavy load.

A useful first step is a compassionate inventory: are the conditions of your current life nurturing or depleting your nervous system? Not as a judgment, but as data. If you are not living in a way that biologically supports regulation, you should expect to feel dysregulated. That’s not brokenness. It’s cause and effect.

Reason Two: The Nervous System Is No Longer Interpreting Accurately

The second reason is more internal. A nervous system that has been under sustained stress, or that carries a significant load of unprocessed past experience, can develop a kind of hypersensitivity. It starts reading threat where there isn’t one. And when that’s happening, knowing you’re safe logically doesn’t translate to feeling safe.

Think about a car alarm calibrated too sensitively. It was designed to protect the car, and it still serves that purpose. But now it’s triggered by anyone walking nearby, not just by an actual threat. It fires constantly, burning out the battery. A nervous system that has learned to expect danger will do the same thing: scan for and find threats everywhere, wear itself out staying on alert, and resist settling back to baseline even when things are genuinely fine.

There are two reasons this misinterpretation happens. First, your current stress load might be high enough that you’re temporarily wearing yellow or red glasses. The same trigger that you handle easily on a calm day becomes overwhelming when the bucket is already full. Second, past experiences may have created hypersensitivity that persists even when circumstances change. Your nervous system learned a pattern and kept applying it.

One important feature of the nervous system is that it always predicts more of what it has experienced. It prefers familiarity over comfort. A nervous system that has spent years in activation or shutdown has learned those states as normal. When regulation starts to come online, it can feel strange, vulnerable, or even unsafe, not because regulation is bad, but because it’s unfamiliar. This is why clients sometimes describe being anxious about feeling less anxious. It’s the system preferring known dysregulation over unknown calm. Re-familiarizing the nervous system with regulation is slow work, and it requires patience.

Your Parts: The Patterns That Run in the Background
The Three Primary States

Closely connected to the misinterpretation problem is something called parts work, drawn from a therapeutic approach called Internal Family Systems (IFS). The premise is that we all carry different sub-personalities, or parts, that developed at various points in our lives to help us cope with difficulty. These parts have their own thoughts, feelings, and motivations rooted in past experience.

There are two primary types of protective parts. Proactive protectors try to keep you in control and prevent painful emotions before they arise. These often look like perfectionism, people-pleasing, or overanalyzing. Reactive protectors step in when you’re already in distress, trying to quickly numb or distract. These might show up as avoidance, overworking, or compulsive scrolling.

These parts are not bad. They developed at times in your life when you genuinely needed them. The difficulty is that parts can get stuck in the past, still operating as if the original circumstances that created them are still present. When a protective part is running the show, your perception of the present gets filtered through the lens of a much younger, more frightened version of you.

For example: I have a highly productive, overachieving part that works hard to keep everything under control and prevent any sense of inadequacy or failure. It tells me: keep pushing, there’s always more to do, if you slow down everything will fall apart. That part developed when I was a teenager and my mom became seriously ill. As the oldest sibling, I felt responsible for holding things together. That part helped me feel some sense of control during a genuinely chaotic time. But when she takes over now, I take on too much, struggle to ask for help, operate with urgency that isn’t real, and end up burned out. She’s still responding to a reality that no longer exists.

The key to working with parts is not to push them away or be frustrated with them. It’s to turn toward them with curiosity, acknowledge what they were trying to do, and help them see that you don’t need that protection in the same way anymore. This is the rewiring work, and it’s most effective once there is enough nervous system regulation capacity to hold it.

Alongside these protective parts, we all have a wise, regulated self that has been there all along. For many people, that self has been hard to access because the parts have been running the show for so long. One of the most meaningful shifts in healing is beginning to recognize when a part is in the driver’s seat versus when your regulated self is, and gently working to give that regulated self more room.

Bringing It Together

Dysregulation happens and persists for two primary reasons: the conditions of daily life are stacked against the nervous system, or the nervous system has learned to misinterpret present circumstances through the lens of past experience. Often both are true simultaneously.

Healing, through this framework, means addressing both. It means building more biologically supportive daily conditions, the stress bucket work we’ll go deeper on next week, and it means building awareness of the parts and patterns that are shaping perception. None of this requires you to be broken first. Your symptoms already make sense. That’s the starting point. If you want support working through what’s unique to your system, RESTORE is the one-on-one program where we do exactly that work, including comprehensive bloodwork to remove the guesswork from the physiological side.

Three Tangible Takeaways

1. Your symptoms make sense. Anxiety and depression are often natural responses to overwhelming circumstances, not evidence of a broken or disordered system. Understanding the conditions and past experiences that are contributing to yours is the first step toward changing them.
2. How you live directly shapes how you feel. Too many stressors and too little support keeps the nervous system in survival mode regardless of how much inner work you’re doing. Addressing the conditions of daily life is not optional in healing.
3. Your nervous system may be misreading the present through the lens of the past. Hypersensitivity from past stress or trauma, and the protective parts that developed alongside it, can cause your system to perceive threat where there isn’t one. Recognizing these patterns and working with them rather than against them is central to long-term regulation.
