How to Regulate Your Nervous System: Science-Backed Techniques for Anxiety and Stress
In today’s fast-paced world—where work, relationships, and constant digital noise pull us in every direction—it’s no surprise many of us are asking: How can I stay calm? How do I feel like myself again?
A term gaining traction in wellness and science spaces is “regulate your nervous system.” But what does that really mean—and is it even possible?
In this guide, we’ll explore what nervous system regulation actually involves, how stress affects your body, and what real, evidence-based techniques can help you return to balance. Whether you're recovering from burnout, managing anxiety, or just trying to find more peace in your day, this post offers science-backed strategies—without the hype.
What Is the Nervous SysteM—and Why Does It Matter?
The nervous system is your body’s command center. It controls everything from heart rate and digestion to emotional responses and memory. A critical part of this system is the autonomic nervous system (ANS), which manages involuntary bodily functions like heartbeat and breathing (Cleveland Clinic).
The ANS has two main branches:
Sympathetic Nervous System (SNS): Often called the "fight-or-flight" system, it increases heart rate, halts digestion, and heightens alertness in response to perceived threats (Cleveland Clinic).
Parasympathetic Nervous System (PNS): Known as the "rest-and-digest" system, it helps the body relax, recover, and heal (HSS).
Contrary to popular belief, the goal isn't to be relaxed all the time. True well-being depends on nervous system flexibility—the ability to shift into alertness when needed, and return to calm afterward. Chronic stress can impair this flexibility, leaving us stuck in survival mode.
What Is Nervous SysteM Dysregulation?
When chronic stress, trauma, or burnout keep your body stuck in overdrive, it results in nervous system dysregulation. In this state, your system struggles to return to baseline after activation (APA).
CoMMon signs include:
Difficulty sleeping or relaxing
Constant muscle tension
Digestive issues
Emotional reactivity or numbness
Difficulty focusing or feeling scattered
It’s important to remember: dysregulation isn’t a personal failure. It’s a protective response that’s become overactive.
Can You Really Regulate Your Nervous SysteM?
The short answer? Not exactly—at least, not in the way it's often portrayed.
As the Birchwood Clinic explains, the phrase “nervous system regulation” is often misunderstood. Because the autonomic nervous system operates involuntarily, we can’t directly control it—just like we can’t choose when to blink or digest food (Birchwood Clinic).
However, we can influence it.
According to Dr. Andrew Huberman, a neuroscientist at Stanford University, we can “steer” the nervous system toward balance using specific tools and behaviors that shift how our brain interprets safety, effort, and recovery (Huberman Lab).
The key is consistency—not instant fixes.
Science-Backed Techniques to Support Nervous SysteM Regulation
Everyone's nervous system is different, but the following research-supported tools can promote balance and resilience:
1. The Physiological Sigh (Breathwork)
This simple breathing technique—two inhales through the nose, followed by a slow exhale through the mouth—has been shown to reduce arousal and return the body to baseline (Huberman Lab).
Try it:
Inhale deeply through your nose. Take a second, short inhale. Then exhale slowly through your mouth. Repeat 1–3 times.
2. Grounding Through Sensory Input
Grounding techniques help shift your attention from mental overwhelm to physical presence by engaging the senses. These include:
Running cold water over your hands
Pressing your feet firmly into the floor
Naming five things you can see or hear right now
These techniques can help reorient the brain away from threat loops and into the present (PositivePsychology.com).
3. Cold Exposure to Build Resilience
Brief, controlled cold exposure—like splashing cold water on your face or taking a short cold shower—activates the sympathetic nervous system. Repeated exposure helps train your body to recover more quickly, building nervous system resilience (Huberman Lab).
Note: Start gradually and avoid if you have heart conditions or medical sensitivities.
4. SoMatic Awareness
Somatic awareness is the practice of tuning into internal body sensations—like tension, temperature, or pressure—rather than focusing on thoughts.
You might notice:
A clenched jaw
Rapid heartbeat
Tightness in your chest or gut
Your body often detects dysregulation before your mind does. Building this awareness allows for earlier, gentler intervention (Birchwood Clinic).
5. Movement, Sleep, and NourishMent
Everyday habits also regulate the nervous system:
Gentle movement (like walking or stretching) releases stress
Quality sleep restores autonomic balance
Balanced meals stabilize blood sugar, preventing anxiety-like crashes
These basic practices are essential cues of safety for your physiology (APA).
Why Co-Regulation Matters More Than Self-Regulation
Most advice emphasizes self-regulation—but we're biologically wired for co-regulation. According to PositivePsychology.com, we evolved to regulate our nervous systems in safe connection with others.
Real-world exaMples:
A calm voice from a loved one lowers your heart rate
Sitting with a grounded friend helps your body settle
Eye contact or a hug shifts you out of fight-or-flight mode
Soothing social interaction isn’t a crutch—it’s a core regulation tool.
Real-Life ExaMple: A Manager’s Midday Reset
Let’s say you're a team leader in back-to-back Zoom calls. Your heart’s racing, your jaw is tight, and you can’t focus.
Here’s how to apply the tools:
Somatic Check-In: You pause and notice your clenched shoulders
Breathwork: You try two rounds of the physiological sigh
Grounding: You press your feet into the floor and name five nearby objects
Co-Regulation: You call a calm coworker for a quick break
Recovery: You end the day with a nourishing meal and a short walk
You didn’t force calm. You created the conditions for calm to return.
Nervous System Flexibility Looks Different for Everyone
There’s no universal formula. What works for one person may not work for another:
Cold exposure may help one person and overwhelm another
Breathwork may ground some and trigger others with trauma histories
Somatic awareness can feel calming—or uncomfortable—depending on one’s past
Regulation isn’t about doing it right. It’s about responding to what your system needs now—with curiosity instead of judgment.
Real Regulation Begins with Safety
At its core, your nervous system isn’t just looking for calm. It’s looking for safety.
So the question becomes: What helps you feel safe enough to soften?
That might mean stepping outside, turning off the news, or calling a friend. The answer isn’t always technical—it’s often deeply personal.
Final Thoughts: Start Small, Stay Gentle
Regulating your nervous system isn’t about controlling it—it’s about building a compassionate relationship with your body.

Notice how your body responds
Be patient—healing is not a performance
