How do I know if my nervous system is dysregulated?
If you’re anything like me and you've ever felt "on edge" for no specific reason, snapped at someone over something small, or dealt with a crash from exhaustion after a normal day, you may have wondered whether something deeper is going on. One possibility worth understanding is nervous system dysregulation — a state where your body's stress-response system struggles to return to baseline (or find its equilibrium) after being activated.
This isn't a diagnosis, and it isn't something you can self-test your way into knowing for certain. But learning the common signs and symptoms can help you recognize patterns in your own life and figure out when it might be time to seek support in a way that focuses specifically on nervous system regulation. I noticed a HUGE difference when I started incorporating more holistic wellness practices focused on the mind, body & soul, rather than just one of the three. As always, take what serves you and leaves the rest… but for me, I noticed one hell of a difference when I added practices like yoga (specifically yin/restorative/slow flow), meditation/breathwork, EFT tapping, reiki, massage, etc. to my already existent wellness routine of lifting/walking in the gym, going to therapy, and eating a high protein, balanced diet.
What "Regulated" Actually Means
Your autonomic nervous system has two main branches:
The sympathetic branch — think the “gas pedal”. It activates fight-or-flight responses: increased heart rate, shallow breathing, muscle tension, heightened alertness. The sympathetic system drives the fight-or-flight response, preparing you for action during stress.
The parasympathetic branch — think the “brake”. It governs rest, digestion, connection, and recovery. The parasympathetic system dictates the “rest and digest” state, focusing on relaxation, healing, and energy conservation.
A regulated nervous system moves fluidly between these states. It ramps up when there's a real demand (ex: a deadline, slamming on your brakes to avoid an accident) and settles back down once the demand passes (ex: unwinding after dinner). A dysregulated nervous system gets stuck — either wound up in high alert, collapsed into shutdown, or swinging unpredictably between the two.
Signs Your Nervous System May Be Dysregulated
Physical signs
Chronic muscle tension, especially in the jaw, shoulders, or neck
Digestive issues that flare up with stress (or seemingly for no reason)
Trouble falling asleep, staying asleep, oversleeping, or waking up feeling unrested — this one was big for me. When my nervous system is out of balance, I tend to sleep more than normal and still wake up feeling unrested.
A racing heart or shallow breathing during non-threatening situations
Feeling exhausted yet "wired" or anxious at the same time
Getting sick often, or slow recovery from minor illness (this was a really big one for me — I dealt with a lot of sports injuries and frequent illnesses, especially when I was in high school and knew nothing about any of this… which is why I’m so big on sharing this information now)
Emotional signs
Feeling irritable, reactive, or on edge more often than not
Emotional responses that feel disproportionate to the situation
Difficulty feeling calm even when nothing is "wrong" — constantly feeling “on edge'“
Numbness or a sense of being disconnected from your feelings — this is something I still experience when I’m not focused on taking care of myself in a balanced way (mind, body, and soul equally).
Waves of anxiety or dread that seem to come out of nowhere & for no specific reason
Cognitive signs
Trouble concentrating or a foggy, scattered feeling — this was another big one for me & still one that is a “warning sign” for me. When I experience these “warning signs” (as I like to call them), I take it as a nudge to slow down and take better care of myself from a nervous system level.
Difficulty making decisions, even small ones (AKA: being indecisive)
Racing thoughts, especially at night — this was another really big one I experienced in my late teens/early 20’s, truly until I committed my life to daily practices like brain dump journaling, yoga (specifically yin/restorative/slow flow yoga), meditation, breath work, and emotional freedom technique (EFT) tapping.
Feeling like you're constantly bracing for something to go wrong — yep, another big one for me! I constantly felt like I was “waiting for the other shoe to drop.”
Behavioral signs
Avoiding situations that involve conflict, unpredictability, or social demands — another warning sign for me that I need to slow down and take better care of myself is when I start to isolate from others or when I’m having a hard time standing up for myself and setting boundaries… that’s a whole other topic for a different day because I have sooo much to say about what I’ve learned about this specifically!
Relying heavily on substances, food, scrolling/social media, or other habits to "come down" — for me, this even looked like perfectionism when it came to school/work tasks, goals, and projects. I assumed because I was doing things that were “productive” it wasn’t a negative thing, but I soon learned that I was using school and work (especially my wellness/life coaching business) as a form of distraction disguised as productivity & ambition.
Difficulty relaxing, or feeling guilty when you try to rest… for me, this looked like always feeling like I wasn’t allowed to rest until everything was done — which now I know is a very unrealistic and unsustainable way to move through life because there is ALWAYS more to be done. It’s so crucial for us to slow down and take care of ourselves so we can sustain our lives long term.
Swinging between overextending yourself and total shutdown — and the guilt that comes with this!
Startling easily at sounds, touch, or sudden movement — constantly being “on edge”
The Four Common Stress Responses
Dysregulation often shows up as one (or a mix) of these patterns:
Fight — irritability, defensiveness, a short fuse
Flight — restlessness, overworking, avoidance, difficulty sitting still
Freeze — feeling stuck, numb, or unable to act even when you want to
Fawn — people-pleasing, difficulty setting boundaries, prioritizing others' comfort over your own needs — this one showed up BIG TIME for me!
Most people lean toward one or two of these under stress, though it can shift depending on the situation.
Why This Happens
Nervous system dysregulation isn't a character flaw or a sign of weakness. It can develop from:
Chronic or acute stress
Unresolved trauma
Ongoing lack of sleep or recovery time (AKA: chronic fatigue/exhaustion)
Environments that feel unpredictable or unsafe — your physical environment plays such a key role in all of this!
Physical health conditions that affect the nervous system
The body adapts to protect you. Over time, though, a system that's constantly bracing for threat can start to feel like your "normal," even when it's costing you.
What Can Help
Small, consistent practices tend to be more effective than occasional big efforts. Some places to start:
Breathwork — slow, extended exhales signal safety to your nervous system. I really love “alternate nostril breathing” and “box breathing” specifically, but even just becoming aware of your breath can really help ground you back down into the present moment and start to regulate your nervous system.
Movement — walking, stretching/yoga, or shaking out tension helps discharge stress hormones — I’ve even noticed that going to the gym and strength training (specifically while listening to an uplifting/inspiring podcast or feel good playlist) can be super helpful.
Grounding techniques — orienting to your senses (what you see, hear, feel) can interrupt a stress spiral — or even going outside barefoot and grounding your feet into the earth.
Consistent sleep and rest rhythms — regularity matters more than perfection (even if you’re like me and work night shift!) Although my sleep schedule looks a hell of a lot different than most people I know, I’ve found a routine that works for me and my life.
Co-regulation — spending time with people who (and in spaces that) help you feel calm and safe, being mindful of people who make you feel the opposite, and adjusting & editing your life accordingly!
Professional support — a therapist trained in somatic or trauma-informed approaches can help you work with your nervous system rather than against it. I also really love going to get reiki or massages to tap deeper into my physical and energetic healing.
When to Reach Out for Support
If these patterns are affecting your relationships, work, or day-to-day functioning, it's worth talking to a doctor or mental health professional. They can help rule out underlying medical causes and offer tools tailored to your specific situation — something a blog post never can.
