Cortisol blocks the production and regulation of serotonin and dopamine—key neurotransmitters for mood stability. This hormonal imbalance contributes to depressive symptoms.
Symptoms of Nervous System Dysregulation
How to recognize if your body is stuck in survival mode - and what to do about it
Persistent Fight-or-Flight Response
Consider these three scenarios:
- You’re hiking on a trail when you suddenly spot a bear 100 feet away, moving toward you.
- You’re bracing for a difficult conversation with a family member.
- You’ve just learned about a tight deadline you’re unlikely to meet.
What do they have in common? Each can trigger your body’s “fight-or-flight” response.
In the first scenario, this survival mechanism could save your life. But in everyday situations like the second and third, this heightened state leads to a cascade of issues that can seriously impact long-term health.
Today, many people find themselves trapped in a constant reactive state, prompting a growing search for effective ways to regain balance and control.
7 Signs Your Nervous System is Dysregulated
Our bodies can handle small doses of stress, but chronic stress overextends our system, causing imbalances that damage both mental and physical health.
Other common causes of stress include gut issues, poor diet, trauma, accidents, high inflammation, post-viral syndromes, and symptoms like Post-Viral Fatigue, which can lead to nervous system dysregulation.
Chronic stress causes persistently high levels of cortisol and adrenaline, which block the production of other hormones critical to emotional stability and physical recovery.
Here is how hormonal imbalances affect our body:
Prolonged cortisol release blocks melatonin - the sleep hormone. This disruption in circadian rhythms leaves you exhausted but unable to rest effectively.
Cortisol levels negatively affect the gut lining, alter gut microbiota composition, and impair digestion. This mechanism can lead to symptoms like bloating, reflux, nausea, or irritable gut.
An overflow of adrenaline and norepinephrine heighten physical and emotional arousal, triggering anxious thoughts and panic responses even in non-threatening situations.
Cortisol suppresses the immune system by reducing the activity of lymphocytes and inhibiting the production of pro-inflammatory cytokines needed to fight infections. This makes the body vulnerable to illnesses and slows down healing.
Chronic exposure to cortisol damages the hippocampus, the brain region critical for memory and learning. This hormonal impact reduces cognitive function, leading to difficulties with focus, memory retention, and problem-solving.
Chronic stress reduces HRV, which is a critical indicator of how well the autonomic nervous system manages stress and recovery. Low HRV is associated with an increased risk of cardiovascular issues, poor emotional regulation, and an overall weakened stress response.
These mechanisms create a domino effect, perpetuating poor health and severely impacting overall well-being.
AVNT™ – The Scientific Path to Repairing Our System
Auricular vagus nerve therapy (AVNT™) is a scientifically validated, non-invasive method to counteract system imbalance. It uses small doses of electricity to activate the nerve fibers responsible for maintaining emotional stability and regulating physical health.
The vagus nerve is the part of our nervous system responsible for controlling most of our involuntary bodily functions such as heart rate, digestion, and immune response.
By activating the vagus nerve with targeted electrical signals to specific fibers , AVNT™ promotes the "rest-and-digest" response, shifting the nervous system to release neurotransmitters, which help to reduce inflammation, lower heart rate, and improve mood regulation.
Nurosym's team has - published peer-reviewed research for over a decade, reviewed thousands of scientific papers and conducted 50+ scientific studies, that support the efficacy of AVNT™ as an advanced intervention to restore balance and improve physiological health.
