Adrenaline surges are a common experience for many people with POTS. When circulation changes—especially when standing—the body may release adrenaline to help maintain blood flow to the brain. This response can increase heart rate and alertness, but it may also cause symptoms like shakiness, dizziness, and a sudden anxious feeling.

Your sympathetic nervous system controls the body’s fight-or-flight response.

When activated, it increases heart rate, raises blood pressure, and releases stress hormones to help the body react quickly.

In POTS and dysautonomia, this system may stay overactive, contributing to symptoms like tachycardia, dizziness, fatigue, and overstimulation.

Supporting your body with hydration, electrolytes, and rest can help maintain autonomic balance.

Your nervous system works best in balance.

The sympathetic system helps you respond to stress.
The parasympathetic system helps your body recover.

In POTS, this balance can become disrupted — which is why hydration, electrolytes, and recovery strategies matter.

The parasympathetic nervous system helps the body slow down and recover.

It supports digestion, relaxation, and healing after stress.

Healthy autonomic function depends on balance between fight-or-flight and rest-and-recover systems.

Your body has a system that controls things you don’t have to think about.

Heart rate.
Blood pressure.
Circulation.
Digestion.

This system is called the autonomic nervous system.

It has two main branches: the sympathetic (fight or flight) and parasympathetic (rest and recovery) systems.

When these systems become unbalanced, symptoms like those seen in POTS can occur.

Understanding this system is the first step to understanding dysautonomia.

POTS symptoms don’t always stay the same throughout the day.

The autonomic nervous system is constantly adjusting to things like posture, hydration, temperature, and stress. When regulation is disrupted, symptoms can fluctuate.

That’s why some moments may feel manageable while others are more challenging.

Supporting hydration, electrolyte balance, and recovery can help support circulation and stability throughout the day.

What happens when autonomic regulation is disrupted?

The systems that control heart rate, blood pressure, and circulation stop working smoothly — which can lead to symptoms seen in POTS and dysautonomia.

Understanding the nervous system helps explain the symptoms.

Dysautonomia affects more than just one symptom — it affects the entire autonomic nervous system.

The ANS controls automatic functions like heart rate, blood pressure, circulation, digestion, and temperature. When regulation is disrupted, symptoms can appear across multiple body systems.

That’s why people with POTS may experience dizziness, fatigue, brain fog, tachycardia, and more.

Supporting hydration, sodium intake, and electrolyte balance can help support circulation and blood volume.

Your autonomic nervous system controls the automatic functions that keep your body running — heart rate, circulation, breathing, digestion, and more.

It works through two systems:

• Sympathetic → “fight or flight”
• Parasympathetic → “rest and digest”

In POTS and dysautonomia, this system can become dysregulated, which may lead to symptoms like dizziness, tachycardia, fatigue, and brain fog.

Understanding the nervous system can help explain why symptoms happen.

POTS is often called an invisible illness for a reason.

The symptoms people experience every day may not be obvious from the outside — but they are very real.

More awareness helps people better understand dysautonomia and those living with it.
