The basics

Your nervous system

Your nervous system is built in two halves that constantly talk to each other: one commanding, one carrying out.

• Central nervous systemThe brain is the command center: processing, decisions, and emotion regulation. The spinal cord relays messages between brain and body.
• Peripheral nervous systemThe somatic part handles voluntary movement and the senses. The autonomic part runs what you do not think about, and splits into sympathetic ("fight or flight") and parasympathetic ("rest and digest").

The basics

The parasympathetic system

Your body is always working to keep things stable, a state called homeostasis. The parasympathetic nervous system is the calm, restful side of that balance, helping you recover once the day's demands have passed.

• HeartSlows the heartbeat.
• LungsDeeper, fuller breaths.
• EyesPupils get smaller.
• BrainSupports a calm state.
• DigestionGets the gut moving.
• MusclesLowers tension.

The basics

The vagus nerve

The vagus nerve is cranial nerve X, the longest nerve of the autonomic nervous system. It runs from your brainstem down through the body, connecting to your heart, lungs, and digestive tract.

When things get intense, the vagus nerve helps switch the parasympathetic system back on. It tells your heart to ease off and your breathing to slow down.

The basics

Polyvagal theory: the three gears

• Green gear: social engagementCalm, connected, and safe. You can chat, laugh, and be fully present.
• Yellow gear: mobilizationAction mode. Heart races, senses sharpen, ready to fight or get away.
• Red gear: immobilizationFreeze. The body shuts down and disconnects when danger feels overwhelming.

No gear is wrong. Each is your body doing what it was built to do.

Polyvagal theory was introduced by Dr. Stephen Porges. It is a popular way to picture the stress response, and researchers still debate parts of it. Use the three gears as a simple map, not as settled science.

Notice

Regulation and co-regulation

• RegulationManaging your emotional and physical state: shifting from high stress to calm, or from sluggish to alert.
• DysregulationStruggling to manage your emotional state, which over time can strain health and relationships.
• Co-regulationPeople helping each other find balance and calm, like two people comforting each other after a hard day.

Build

Resilience

Resilience is your ability to keep your balance, or get it back quickly, when things are hard.

• Build supportive networks
• Practice reflection
• Make time for self-care
• Name your purpose
• Look for what is going well
• Act early

Practice

Ways to settle your body

Each of these is a gentle way to nudge your body toward its calm, restful side. Try one, go slowly, and stop if it does not feel right.

• Slow breathingBreathe in for 4, hold for 4, breathe out for 6. Repeat 5 to 10 times, twice a day.
• Face warm-upWarm your hands, rest them on your face, and playfully reshape your expression.
• Tongue releaseOpen wide to stretch the throat, then explore your mouth gently with your tongue.
• Butterfly hugCross your arms, hands on opposite collarbones, and tap left and right for 8 counts.
• A long hugA long hug with someone you trust is linked with lower stress for many people.
• Mindful swallowingLet saliva gather, then swallow slowly, up to 20 times, chin down.
• HummingLie down and hum for a few minutes, feeling it through your chest and neck.
• PalmingRest your warm palms over your closed eyes without pressing, and breathe slowly.
• Soothing hand positionsOne hand on your heart and one on your belly, or on your forehead, for 5 to 15 minutes.
• Breath meditationFollow your breath's natural rhythm for 10 to 15 minutes a day.

Closing reflection

Three things I am grateful for today

Your nervous system is something to understand, and to keep coming home to.

Education, not treatment. Everything here is wellness education and self-care you practice yourself. It works alongside your doctor, your counselor, or your therapist, not in place of them.
