How to Regulate a Dysregulated Nervous System

A dysregulated nervous system can impact every aspect of life, from mental health to physical well-being. When your body struggles to maintain balance, it can leave you feeling stuck in states of stress, fatigue, or emotional overwhelm. Understanding how to regulate your nervous system is a crucial step toward recovery and resilience.

At Tennessee Valley Recovery, we specialize in helping individuals restore nervous system balance through evidence-based and holistic approaches. This guide explores nervous system dysregulation, its symptoms, causes, and actionable tools for long-term regulation.

Understanding the Nervous System

To fully grasp how to regulate a nervous system, it’s essential to understand how the nervous system operates. The autonomic nervous system (ANS) is key in managing your body’s automatic functions, such as heart rate, digestion, and stress responses. Functioning correctly helps you adapt to challenges and return to a state of balance. However, dysregulation can occur when this system is overwhelmed or unable to reset properly.

What is a Dysregulated Nervous System?

The nervous system is the body’s control center, managing responses to stress and maintaining internal balance. Dysregulation occurs when the autonomic nervous system (ANS) becomes stuck in a state of hyperarousal (fight-or-flight), or hypoarousal (freeze or shutdown).

The Autonomic Nervous System: Sympathetic vs. Parasympathetic

The autonomic nervous system (ANS) is a key part of the body’s internal regulation system. It operates automatically, without conscious effort, to manage essential functions like heart rate, breathing, digestion, and stress responses. 

Within the ANS, two primary branches—the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS)—work together to maintain balance and adaptability.

The Sympathetic Nervous System (SNS): Fight or Flight

The sympathetic nervous system is often called the “fight-or-flight” system because it prepares the body to respond to perceived threats or stressors. When activated, it triggers physiological changes to enhance survival, including:

  • Increased Heart Rate: To pump more oxygen and nutrients to muscles.
  • Rapid Breathing: To supply more oxygen to the bloodstream.
  • Pupil Dilation: To improve vision and focus during emergencies.
  • Suppressed Digestion: To redirect energy to immediate survival needs.

While these responses are vital in short-term stressful situations, chronic activation of the SNS due to prolonged stress can lead to a dysregulated and overactive nervous system, resulting in symptoms like anxiety, irritability, and exhaustion.

The Parasympathetic Nervous System (PNS): Rest and Digest

The parasympathetic nervous system acts as the body’s “rest-and-digest” system, working to restore balance after stress or exertion. When the PNS is active, it promotes recovery and relaxation by:

  • Slowing Heart Rate: Allowing the body to conserve energy.
  • Enhancing Digestion: Supporting nutrient absorption and metabolism.
  • Relaxing Muscles: Reducing tension and promoting physical recovery.
  • Encouraging Sleep: Creating a calm state conducive to rest and repair.

Activation of the PNS is essential for counterbalancing the SNS. A well-regulated PNS helps prevent burnout, supports emotional stability, and allows the body to heal from stress.

The Sympathetic and Parasympathetic Balance

A healthy autonomic nervous system alternates seamlessly between the sympathetic and parasympathetic states depending on your needs. 

For example:

During exercise, the SNS increases heart rate and energy to support physical activity.

After exercise, the PNS activates to lower heart rate, relax muscles, and facilitate recovery.

However, an unbalanced nervous system can cause the ANS to become stuck in one state, either overactive (SNS dominance) or underactive (PNS dominance). This imbalance can lead to chronic stress, emotional instability, or physical symptoms such as fatigue or digestive problems.

Understanding the interplay between the SNS and PNS is fundamental to learning how to heal a dysregulated nervous system. Techniques that activate the PNS, such as breathing exercises, mindfulness, and vagus nerve stimulation, can help restore balance and promote long-term health. By addressing both branches of the ANS, individuals can achieve a greater sense of stability and resilience.

Signs of a Dysregulated Nervous System

Dysregulation can manifest in a variety of ways, impacting physical, emotional, and cognitive well-being. Recognizing the signs of dysregulation is the first step in understanding its effects and seeking appropriate treatment. These signs often indicate that the autonomic nervous system is stuck in a state of hyperarousal (fight-or-flight) or hypoarousal (freeze or shutdown), preventing the body from achieving balance.

Physical Signs of Dysregulation

The nervous system controls involuntary functions like heart rate, digestion, and breathing. When dysregulated, these processes can be disrupted, resulting in physical symptoms such as:

  • Chronic Fatigue: Persistent exhaustion that isn’t relieved by rest or sleep.
  • Headaches or Migraines: Stress and tension can trigger recurring headaches.
  • Digestive Issues: Problems like indigestion, constipation, or irritable bowel syndrome (IBS) may occur due to suppressed digestive processes.
  • Muscle Tension: Tightness or pain in the neck, shoulders, or jaw is common.
  • Sleep Disturbances: Difficulty falling asleep, staying asleep, or achieving restful sleep.

These symptoms often persist despite lifestyle adjustments, signaling the need for targeted regulation techniques.

Emotional Signs of Dysregulation

The nervous system directly influences emotional responses. Dysregulation can lead to heightened or suppressed emotions, such as:

  • Anxiety: A constant sense of worry, fear, or hypervigilance, often accompanied by a racing heart or shallow breathing.
  • Depression: Feelings of sadness, hopelessness, or emotional numbness, particularly in a hypoarousal state.
  • Irritability or Anger: Difficulty managing frustration or controlling emotional outbursts.
  • Emotional Numbness: A lack of connection to feelings or an inability to experience joy or excitement.

These emotional signs are often mistaken for standalone mental health conditions, but they can be rooted in an unregulated nervous system.

Cognitive Signs of Dysregulation

Dysregulation of the nervous system can also impair cognitive functions, leading to symptoms such as:

  • Brain Fog: Difficulty concentrating, mental fatigue, and a general sense of confusion.
  • Poor Memory: Trouble recalling information or staying focused on tasks.
  • Overthinking: Repetitive, intrusive thoughts that prevent mental clarity.

Cognitive symptoms often worsen with prolonged stress or unresolved emotional trauma.

Behavioral Signs of Dysregulation

Behavioral changes are another key indicator of dysregulation. These may include:

  • Avoidance: Withdrawing from social situations or responsibilities due to overwhelm.
  • Compulsive Behaviors: Engaging in repetitive actions, such as overeating or overworking, as a coping mechanism.
  • Procrastination or Inactivity: Struggling to initiate or complete tasks due to fatigue or low motivation.

These behaviors can disrupt daily life and relationships, further perpetuating the cycle of dysregulation.

Hyperarousal vs. Hypoarousal States

The signs of a dysregulation of the nervous system often depend on whether the ANS is in hyperarousal or hypoarousal:

  • Hyperarousal (Fight-or-Flight): Anxiety, restlessness, rapid heartbeat, and an inability to relax.
  • Hypoarousal (Freeze or Shutdown): Fatigue, disconnection, emotional numbness, and reduced energy.

Many individuals fluctuate between these states, making it essential to identify and address both extremes for effective regulation.

How to Regulate Your Nervous System

Learning how to regulate the nervous system is essential for restoring balance and improving overall well-being. Whether caused by chronic stress, trauma, or lifestyle factors, a nervous system imbalance can leave you feeling stuck in states of hyperarousal or hypoarousal. 

Thankfully, a variety of tools and techniques can help you regain control, calm your mind, and support your body’s natural ability to self-regulate. From breathing exercises to mindfulness practices, these strategies empower you to address the root causes of dysregulation and build resilience for long-term health.

Breathing Techniques

Deep, intentional breathing activates the parasympathetic nervous system, promoting relaxation.

  • Diaphragmatic Breathing: Focuses on deep breaths into the belly.
  • Box Breathing: Involves inhaling, holding, exhaling, and pausing for equal counts.
  • 4-7-8 Breathing: Combines longer exhales to calm the nervous system.
  • Coherent Breathing: Maintains a steady breathing pace of five breaths per minute.

These practices can immediately ease symptoms of an overactive nervous system.

Somatic Practices

Engaging the body helps release stored tension and restore balance.

  • Progressive Muscle Relaxation: Alternately tenses and releases muscle groups.
  • Body Scanning: Brings awareness to physical sensations, promoting mindfulness.
  • Grounding Exercises: Techniques like the 5-4-3-2-1 method reconnect you to the present moment.

Gentle movements like yoga and tai chi also support regulation.

Vagus Nerve Stimulation

The vagus nerve plays a key role in parasympathetic activation. Several simple, evidence-based methods can activate the vagus nerve, promoting calm and balance:

  • Cold Exposure: Splashing cold water on your face or taking cold showers stimulates the vagus nerve.
  • Humming, Singing, or Chanting: Activates the nerve through vocal vibrations.
  • Gargling: Activates the vagus nerve by engaging the muscles in the back of the throat.
  • Deep Breathing: Breathing exercises, especially diaphragmatic breathing, stimulate the vagus nerve by promoting slow, deep inhalations and exhalations.
  • Acupressure or Massage Techniques: Gentle massages around the neck or ears promote relaxation.

Integrating vagus nerve stimulation techniques into your routine doesn’t require significant time or effort. Simple practices like humming while driving, splashing cold water on your face after exercise, or incorporating deep breathing exercises before bed can have a profound impact on your nervous system health.

By consistently practicing these techniques, you can enhance your ability to regulate stress, recover from challenges, and maintain emotional balance.
