Your Nervous System, Explained

Your nervous system is running in the background of your life, constantly scanning for safety and danger. When it senses a threat—real or perceived—it launches a survival response. Understanding how this works can help you work with your body instead of against it.

Fight, Flight, Freeze, and Fawn

When your nervous system detects danger, it activates one of four responses:

Fight

Your body prepares to confront the threat. You might feel:

• Anger or irritability
• Clenched jaw or fists
• A surge of energy
• The urge to argue, defend, or push back

Flight

Your body prepares to escape. You might feel:

• Panic or intense anxiety
• Racing heart and rapid breathing
• Restlessness or the urge to run
• Difficulty sitting still

Freeze

Your body shuts down to avoid detection or harm. You might feel:

• Numb or disconnected
• Unable to move or speak
• Like you're watching yourself from outside your body
• Paralyzed or stuck

Fawn

Your body tries to appease the threat to stay safe. You might:

• People-please even when it hurts you
• Agree to things you don't want to do
• Lose your sense of boundaries
• Over-apologize or try to fix everything

Why This Happens

These responses evolved to keep you alive. If a bear is chasing you, your nervous system doesn't stop to think—it acts. Your heart races, your muscles tense, your focus narrows. This is your body doing exactly what it's supposed to do.

The problem is, your nervous system can't tell the difference between a bear and an angry email. It responds to modern stressors—work deadlines, difficult conversations, financial stress—the same way it would respond to a physical threat.

What Triggers Your Nervous System

Common triggers include:

• Conflict or confrontation
• Feeling trapped or powerless
• Reminders of past trauma
• Overwhelm or too many demands
• Loneliness or rejection
• Uncertainty or lack of control

Sometimes you know exactly what triggered you. Other times, your body reacts before your brain catches up.

Signs Your Nervous System Is Stuck

When your nervous system stays in survival mode too long, you might notice:

• Constant anxiety or feeling on edge
• Difficulty sleeping or relaxing
• Irritability or anger that feels out of proportion
• Numbness or disconnection from your feelings
• People-pleasing at the expense of your own needs
• Physical symptoms like headaches, digestive issues, or muscle tension

How to Help Your Nervous System Settle

You can't think your way out of a nervous system response. You have to work with your body:

For Fight:

• Move your body—walk, run, punch a pillow
• Express anger safely (journaling, talking to someone you trust)
• Set boundaries

For Flight:

• Ground yourself in the present moment
• Slow, deep breathing
• Name what you see, hear, and feel around you

For Freeze:

• Gentle movement—stretch, shake, sway
• Warm yourself (blanket, warm drink, heating pad)
• Connect with safe people

For Fawn:

• Practice saying no
• Notice when you're over-functioning for others
• Ask yourself: "What do I actually want right now?"

Building Safety

The more your nervous system feels safe, the less it will activate these responses. Things that help:

• Predictable routines
• Safe, supportive relationships
• Adequate sleep and nutrition
• Time in nature
• Creative expression
• Therapy or somatic work

You're Not Broken

If your nervous system is easily triggered, it doesn't mean something is wrong with you. It means your body learned to protect you, probably for good reasons. The goal isn't to never have these responses—it's to help your nervous system feel safe enough to relax.
