How the Nervous System Affects Your Health

Your nervous system runs and powers every organ and every other system, from your brain to your digestion, breathing and beyond. But what many people don't consider is that the natural aging process, toxins and diseases can damage your nervous system, and therefore your overall health.

Understanding Your Nervous System

The nervous system consists of two main parts:

Central Nervous System (CNS)

The brain and spinal cord, which process and coordinate information.

Peripheral Nervous System (PNS)

The network of nerves throughout the body that transmits signals to and from the CNS.

The Autonomic Nervous System and Mental Health

The autonomic nervous system, which controls involuntary functions, has two key branches:

Sympathetic Nervous System ("Fight or Flight")

Activates in response to perceived threats, increasing heart rate, blood pressure, and cortisol levels.

Parasympathetic Nervous System ("Rest and Digest")

Promotes relaxation, recovery, and healing.

How Nervous System Dysregulation Affects Health

When your nervous system is chronically activated in fight-or-flight mode, you may experience:

Regulating Your Nervous System

Deep Breathing

Slow, diaphragmatic breathing activates the parasympathetic nervous system.

Cold Exposure

Brief cold water exposure can help reset the nervous system.

Movement

Gentle movement like yoga, tai chi, or walking helps regulate nervous system function.

Social Connection

Safe, positive social interactions activate the vagus nerve and promote calm.

Professional Support

Therapies like EMDR, somatic experiencing, and neurofeedback directly address nervous system regulation.

Understanding your nervous system is key to understanding your mental and physical health. If you're experiencing symptoms of nervous system dysregulation, therapy can help.
