How to Regulate Your Nervous System: A Therapist’s Guide to Calming Your Body and Mind
Written by Dr. Kait Rosiere, Licensed Psychologist and Eating Disorder Specialist in Orlando, FL
If you've ever felt like your emotions are constantly overwhelming you — like you're either in a state of panic, shutdown, or somewhere in between — there's a good chance your nervous system is stuck in survival mode.
Your nervous system is the control center for how you experience the world. It determines whether you feel safe, alert, anxious, or completely disconnected. And when it's been shaped by stress, trauma, or years of emotional overwhelm, it can get stuck in patterns that keep you feeling on edge — or completely numb.
As an Orlando therapist who specializes in eating disorders and trauma, nervous system regulation is something I work on with almost every client. Because here's the thing: you can't think your way out of a dysregulated nervous system. You have to learn to work with your body.
This guide will help you understand how your nervous system works, why it gets stuck, and what you can do to bring it back into balance.
What Is Nervous System Regulation?
Nervous system regulation refers to your body's ability to move between states of activation and calm in a flexible, adaptive way. When your nervous system is well-regulated, you can:
Feel your emotions without being overwhelmed by them
Respond to stress without shutting down or spiraling
Feel present in your body and connected to the people around you
Recover from difficult moments relatively quickly
When your nervous system is dysregulated, you might:
Feel constantly anxious, on edge, or hypervigilant
Swing between intense emotions and total numbness
Struggle to calm down once you're activated
Feel disconnected from your body, emotions, or surroundings
Use food, substances, or other behaviors to cope with overwhelming feelings
Understanding Your Autonomic Nervous System
Your autonomic nervous system (ANS) operates largely outside of your conscious control. It has three main branches, as described by Dr. Stephen Porges' Polyvagal Theory (Porges, 2011):
1. Ventral Vagal (Safe and Social)
This is your "safe and connected" state. When your ventral vagal system is online, you feel calm, present, and able to connect with others. You can think clearly, engage socially, and handle everyday stress without losing your footing. This is the state we're aiming for — not a state of zero stress, but a state of flexible resilience.
2. Sympathetic (Fight or Flight)
This is your body's alarm system. When your brain detects danger — real or perceived — your sympathetic nervous system kicks in. Your heart rate increases, your muscles tense, your breathing quickens, and your body prepares to fight or run. This is helpful in genuine emergencies, but becomes a problem when it's your default state.
3. Dorsal Vagal (Freeze or Shutdown)
When the threat feels too overwhelming to fight or flee from, your nervous system may shift into a dorsal vagal state — essentially hitting the brakes. This looks like numbness, dissociation, collapse, exhaustion, or feeling "checked out." It's your body's last-resort survival mechanism.
Why Your Nervous System Gets Stuck
Your nervous system is shaped by your experiences — especially your early experiences. If you grew up in an environment that was unpredictable, unsafe, or emotionally neglectful, your nervous system may have learned to stay in a state of high alert (sympathetic activation) or chronic shutdown (dorsal vagal).
Common reasons your nervous system may be stuck include:
Childhood trauma or neglect — your system learned early that the world isn't safe
Complex PTSD — prolonged, repeated trauma keeps your system in survival mode
Insecure attachment — without a safe, co-regulating caregiver, you may not have developed strong self-regulation skills
Chronic stress — ongoing work stress, relationship difficulties, or financial strain can keep your system activated
Eating disorders — malnutrition, bingeing, purging, and restriction all directly impact nervous system functioning
The Window of Tolerance
Psychiatrist Dan Siegel developed the concept of the "window of tolerance" — the zone in which you can experience and process emotions without becoming overwhelmed or shutting down. When you're inside your window, you can handle life's ups and downs. When you're outside it, you're either hyperaroused (anxious, reactive, panicky) or hypoaroused (numb, disconnected, collapsed).
The goal of nervous system regulation isn't to never feel stressed or activated. It's to widen your window of tolerance so you can handle more without tipping into survival mode.10 Ways to Regulate Your Nervous System
The good news is that your nervous system is neuroplastic — it can change. With consistent practice, you can teach your body new patterns of safety and regulation. Here are ten evidence-based strategies:
1. Deep Breathing (Especially Extended Exhales)
Your breath is the most direct way to influence your nervous system. When you lengthen your exhale, you activate the vagus nerve and signal safety to your brain. Try breathing in for 4 counts, holding for 4, and exhaling for 6-8. Even two minutes of this can shift your state (Zaccaro et al., 2018).
2. Grounding Exercises
Grounding brings you back into your body and the present moment. Try the 5-4-3-2-1 technique: notice 5 things you can see, 4 you can touch, 3 you can hear, 2 you can smell, and 1 you can taste. This works by engaging your senses and pulling your attention away from internal distress.
3. Gentle Movement
Movement helps discharge the energy that builds up when your nervous system is activated. This doesn't mean intense exercise — walking, stretching, yoga, or even shaking your body can help complete the stress cycle and bring your system back to baseline.
4. Cold Water on Your Face or Wrists
Splashing cold water on your face activates the dive reflex, which slows your heart rate and helps calm your system. This is a quick, evidence-based tool from Dialectical Behavior Therapy (DBT) for moments of intense distress.
5. Co-Regulation
Your nervous system is wired to be regulated by other nervous systems. Being near someone who is calm and safe can help your body settle. This is why a good therapist, a trusted friend, or even a pet can have such a powerful effect on your emotional state. We learn to self-regulate through co-regulation first.
6. Vagal Toning Exercises
The vagus nerve is the main pathway for calming your nervous system. Activities that stimulate the vagus nerve include: humming, singing, gargling, gentle neck stretches, and placing a hand on your chest while breathing slowly. Regular vagal toning can strengthen your body's ability to return to calm.
7. Orienting to Your Environment
When you feel activated, slowly look around the room and name what you see. Move your head gently from side to side. This simple act tells your nervous system that you are safe in your current environment — that there's no immediate threat.
8. Mindful Eating
For people recovering from eating disorders, learning to eat mindfully — paying attention to the sensory experience of food without judgment — can be a powerful form of nervous system regulation. It engages the ventral vagal system through the act of pausing, tasting, and being present with nourishment.
9. Bilateral Stimulation
Alternating stimulation of both sides of your body — like tapping your knees alternately, walking, or the "butterfly hug" (crossing your arms over your chest and alternately tapping your shoulders) — can help calm your nervous system. This is part of why EMDR therapy is so effective for trauma processing.
10. Creating Routine and Predictability
Your nervous system thrives on predictability. When your daily life has some structure — consistent meal times, a regular sleep schedule, rituals for winding down — your body gets the message that the world is safe and predictable. This is especially important during eating disorder recovery.
Nervous System Regulation and Eating Disorders
Eating disorders are, at their core, nervous system disorders. Restricting, bingeing, purging, and compulsive exercise are all ways the body tries to manage overwhelming emotional states. Research shows that people with eating disorders often have significantly disrupted autonomic nervous system functioning (Peschel et al., 2016).
In eating disorder recovery, learning to regulate your nervous system is essential because:
It helps you tolerate the discomfort of eating when your body sends distress signals
It gives you alternatives to using food behaviors to manage emotions
It helps you stay present in your body rather than disconnecting
It supports the rebuilding of interoceptive awareness — your ability to sense and respond to your body's signals
When to Seek Professional Help
While the strategies above are helpful, they're not a substitute for therapy — especially if your nervous system dysregulation is rooted in trauma. A trained therapist can help you:
Identify your specific patterns of dysregulation
Process the underlying experiences that shaped your nervous system
Build personalized strategies for your unique needs
Provide the co-regulation that is essential for healing
Therapy approaches that specifically address nervous system regulation include DBT, EFT, EMDR, Somatic Experiencing, and CBT.

Frequently Asked Questions
What does a dysregulated nervous system feel like?
A dysregulated nervous system can feel like constant anxiety, emotional overwhelm, numbness, difficulty concentrating, chronic fatigue, or a sense of being "stuck" in survival mode. You may notice physical symptoms like a racing heart, tight muscles, shallow breathing, or digestive issues.
How long does it take to regulate your nervous system?
Individual regulation techniques can calm your nervous system in minutes. However, building long-term nervous system resilience is a gradual process that happens over weeks and months of consistent practice. Working with a therapist can significantly accelerate this process.
Can nervous system dysregulation cause eating disorders?
Nervous system dysregulation is a significant contributing factor to eating disorders. When your body is stuck in a state of chronic stress or shutdown, disordered eating behaviors often develop as coping mechanisms to manage overwhelming internal states.
What is polyvagal theory in simple terms?
Polyvagal theory, developed by Dr. Stephen Porges, explains that your nervous system has three states: safe and connected (ventral vagal), fight or flight (sympathetic), and freeze or shutdown (dorsal vagal). Your body moves between these states based on whether it perceives safety or danger.
