What is the Autonomic Nervous System> 

Autonomic dysfunction occurs when the autonomic nervous system (ANS) loses its ability to regulate the body efficiently and adaptively. The ANS is the control system that runs in the background of your life. It regulates heart rate, blood pressure, digestion, temperature, immune balance, hormone signalling, breathing patterns and your stress response.

When functioning well, this system allows you to shift fluidly between activation (fight or flight) and restoration (rest, repair and digest). When dysregulated, the body can become stuck in survival mode or, conversely, drop into shutdown. Over time, this loss of regulation affects both physical health and mental wellbeing.

Many people with autonomic nervous system dysfunction say, “It feels like my body is broken.” In reality, it is often a system that has become overwhelmed, inflamed or injured.

What are the symptoms of Autonomic Dysfunction?

Because the autonomic nervous system influences nearly every organ system, symptoms can be wide-ranging and confusing.

 

They may include:

• POTS (Postural Orthostatic Tachycardia Syndrome)
• Dizziness or faintness on standing
• Racing or irregular heart rate
• Blood pressure instability
• Chronic fatigue
• Brain fog and memory issues
• Anxiety or panic attacks
• Depression or emotional numbness
• Digestive disturbance (bloating, nausea, constipation, IBS)
• Temperature intolerance
• Sleep disturbance
• Headaches and migraines
• Tremors or internal vibrations
• Heightened sensitivity to light, sound or chemicals

 

Many individuals are told their symptoms are purely psychological. However, autonomic nervous system dysregulation is a physiological condition that profoundly impacts mental health.

What triggers
Autonomic System Dysruption?

Autonomic dysregulation is rarely random. It is commonly triggered by one or more of the following:

• Concussion and head injury
• Whiplash and spinal trauma
• Chronic psychological stress or complex trauma
• Viral illness and post-viral syndromes
• Chronic infections
• Inflammatory and autoimmune processes
• Toxic exposures or poisonings
• Hormonal shifts (including perimenopause)
• Vaccination reactions in susceptible individuals
• Medication withdrawal syndromes
• Surgery or significant physiological stress

 

In clinical practice, it is often the cumulative load of stressors that overwhelms the system. From a holistic perspective, this represents a loss of adaptability and resilience at a cellular and neurological level.

How does it affect
Mental Health?

The autonomic nervous system and the brain are inseparable. When the body is locked in sympathetic overdrive (fight or flight), the brain interprets internal signals as threat. This may present as:

• Chronic anxiety
• Hypervigilance
• Irritability
• Emotional volatility
• Panic attacks

If the system shifts into dorsal vagal shutdown, symptoms may include:

• Low mood
• Apathy
• Dissociation
• Loss of motivation
• Burnout

 

This is why many people with autonomic dysfunction experience both physical symptoms and mood disorders. Treating one without addressing the other often leads to incomplete results.

Restoring Balance

Physical, Mental & Emotional Recovery with FSM

Autonomic Nervous System balance is a crucial foundation for overall health.

When problems occur at this deep level, very little seems to help.

 

Frequency Specific Microcurrent (FSM) is one of the few therapies tuned to this level of recovery.

 

FSM can work at the level of the automonic nervous system, removing the obstacles and obstructions that send the ANS offline, and restoring calm to a dysregulated system. Used alongside a Naturopathic and Holistic medicine framework, this combination of therapies has brought great relief to many clients suffering from this little recognised, yet more commonly experienced, condition.
