Driving Without Brakes: The Hypersensitive Nervous System Explained
When you’re living with chronic fatigue syndrome (CFS), long COVID, or a similar hypersensitive nervous system condition, it can often feel like you’re trapped in a body that’s reacting to everything—and no one can explain why. The symptoms are real, intense, and unpredictable. But what if your body isn’t broken… just stuck in the wrong gear?
One of the most powerful ways to understand what’s happening inside your body is through an analogy—a simple comparison that makes a complex situation easier to grasp. In this case, think of your nervous system like a Formula 1 car trying to navigate rush hour in downtown New York City—without brakes.
Let’s break down what this means and how it can help you better understand your symptoms, reduce anxiety, and begin the path to healing.
You’re Not Broken—You’re Just in the Wrong Gear
During the worst of my illness, I was terrified and confused. I had over 50 unexplained symptoms, from trembling to headaches, dizziness, insomnia, and intense fatigue. At one point, I was so desperate for answers that I thought I might have Parkinson’s. The following week, I was convinced it was Lyme disease. I ran dozens of tests—nothing explained what was happening.
Eventually, in a stroke of luck, I met a doctor who finally made it all make sense. He gave me an analogy that changed everything: my nervous system was like a Formula 1 car—high performance, extremely sensitive, and built for speed—but I was trying to drive it in a world that required careful navigation.
Just like a Formula 1 car can’t handle stoplights, potholes, and sudden turns, my nervous system couldn’t handle even minor stressors. Bright lights, small amounts of screen time, a short walk—things that shouldn’t have been a big deal were suddenly triggering intense reactions.
Understanding the Formula 1 Nervous System
Your nervous system is designed to adapt to different environments, to shift between rest and activity, and to handle a range of stimuli. But in CFS and similar conditions, that adaptability gets lost. Instead of functioning like a balanced vehicle that can shift gears smoothly, your system is stuck in overdrive.
In this state:
-
Small movements trigger big crashes (flare-ups or adjustment periods)
-
Sensory input like light, noise, or movement becomes overwhelming
-
Your heart rate might spike just from standing up
-
You feel wired but tired—like your system is fried but still racing
It’s not all in your head. It’s a physiological response. But it’s also one that can be recalibrated.
Why the Nervous System Gets “Stuck”
Your brain and body can only handle so much stress before they start to protect you. This is called your stress threshold—and when it’s exceeded, the brain puts a limiter on your body. That’s when symptoms appear.
Symptoms are not random or meaningless. They are your body’s way of saying, “That’s too much.” The real issue isn’t in your muscles or digestion or even your immune system. It’s that your brain is overstimulated and hypervigilant. It’s interpreting even safe signals as threats.
Just like a Formula 1 car isn’t meant to drive on city streets, your nervous system isn’t meant to stay in fight-or-flight mode 24/7.
Recalibration: Swapping Out the Engine
Here’s the good news: the nervous system can change. Through a process called neuroplasticity, you can teach your brain to respond differently to the world around you. You can go from driving that ultra-sensitive Formula 1 car to something like a smooth, reliable Honda Civic—designed for everyday life.
That doesn’t happen overnight. It takes time. But with consistent practice, you can retrain your system to:
-
Calm down in response to stress
-
Tolerate more sensory input
-
Feel safe in your own body again
At a certain point, you may even be able to switch back into high-performance mode when needed—like for work, creativity, or athletics—without spiraling into symptoms.
How to Start Calming the Nervous System
To swap out the “engine” and regulate your hypersensitive nervous system, you’ll need tools that create a consistent sense of safety and calm in your body. That’s where techniques like brain retraining, nervous system regulation exercises, and mindset shifts come in.
But more important than any single technique is understanding what you’re doing and why. You’re not trying to “fix” symptoms. You’re trying to retrain the system that creates them.
Start by learning to respond differently to symptoms. Instead of fearing them, try to see them as signs that your nervous system is overloaded and needs a reset. The more calmly and consistently you respond, the more your system begins to shift back toward balance.
You Don’t Have to Drive Blind
This analogy helped me stop spiraling during flare-ups. Every time symptoms hit, I reminded myself: “Okay, my nervous system is just overreacting. I stepped too hard on the gas. I can ease off now.” That shift in understanding helped reduce my anxiety, allowed me to rest, and gave me a sense of control when everything else felt chaotic.
