Understanding Hyperarousal Through the Lens of Polyvagal Theory

The nervous system plays a crucial role in how we experience and respond to the world. According to Polyvagal Theory, developed by Dr. Stephen Porges, our autonomic nervous system (ANS) operates through three primary states: the ventral vagal (social engagement and connection), the sympathetic (mobilization and fight-or-flight), and the dorsal vagal (shutdown and dissociation). When a person experiences hyperarousal, they are in a heightened sympathetic state—characterized by excessive activation, agitation, and anxiety.
What is Hyperarousal?
Hyperarousal occurs when the nervous system is in a state of heightened alertness, often as a response to perceived threats or prolonged stress. Unlike hypoarousal, which is marked by shutdown and disconnection, hyperarousal is an overactivation of the system, leading to excessive energy and difficulty calming down.
Symptoms of Hyperarousal
Hyperarousal affects thoughts, body sensations, and behaviors in distinct ways:
- Cognitive Symptoms: Racing thoughts, difficulty focusing, intrusive memories, heightened worry, or hypervigilance.
- Somatic Symptoms: Increased heart rate, rapid breathing, muscle tension, restlessness, or digestive issues.
- Behavioral Symptoms: Irritability, impulsivity, difficulty sleeping, exaggerated startle response, or avoidance of situations perceived as threatening.
Why Does Hyperarousal Happen?
Hyperarousal is a survival response, where the nervous system perceives danger and remains activated to ensure protection. It is often linked to:
- Acute stress or trauma, where the body remains in a fight-or-flight state even after the threat has passed.
- Early childhood adversity, where hypervigilance develops as a way to anticipate and manage unpredictable environments.
- Chronic stress, such as work pressures, relational conflicts, or societal instability, keeping the system on high alert.
- Unprocessed emotions or trauma, where unresolved distress leads to an overactive nervous system.
Strategies to Downregulate the Nervous System
If you find yourself in a hyperaroused state, the goal is to help the nervous system shift into a more regulated and grounded state. Here are specific strategies:
In the Moment:
- Use Breathwork: Engage in deep, slow breathing, such as box breathing (inhale for 4 seconds, hold for 4 seconds, exhale for 4 seconds, hold for 4 seconds) to signal safety to the body.
- Engage in Progressive Muscle Relaxation: Tense and release different muscle groups to discharge excess energy.
- Ground Through Senses: Use grounding techniques like the 5-4-3-2-1 method (identify five things you see, four things you touch, three things you hear, two things you smell, one thing you taste) to anchor yourself in the present moment.
- Slow, Rhythmic Movement: Engage in gentle movements such as rocking, slow walking, or stretching to bring the body back to regulation.
- Soothing Touch: Place a hand over your heart, apply gentle pressure, or use weighted blankets to create a sense of safety.
Daily Practices to Regulate the Nervous System:
- Mindfulness and Meditation: Engage in daily mindfulness practices to increase self-awareness and nervous system resilience.
- Physical Activity: Regular movement, such as yoga, tai chi, or swimming, can help regulate excess nervous system energy.
- Engaging with Nature: Spending time in natural settings, such as walking in a park or near water, has a calming effect on the nervous system.
- Journaling and Creative Expression: Writing or engaging in artistic activities can help process overwhelming thoughts and emotions.
- Building Safe Connections: Engaging in meaningful conversations, seeking support, and maintaining a sense of community fosters nervous system regulation.
A Final Thought
“The nervous system is our bridge to the world. By learning to listen to and regulate our inner states, we cultivate resilience, presence, and the ability to fully engage with life.”
By understanding hyperarousal and applying these strategies, we can support ourselves and others in navigating moments of heightened stress with compassion and care.
