Explore a self-reflection assessment focused on nervous system balance.
Is Your Nervous System Keeping You in a State of Stress, Anxious Thoughts, or Depression?
Ask yourself
- Is Your Nervous System Contributing to Persistent Stress or Anxious Thoughts?
Some individuals experience ongoing stress, anxious thoughts, or low mood even in the absence of clear external triggers. Research suggests that chronic autonomic nervous system imbalance may influence how the body responds to everyday stimuli.
In these cases, the nervous system may remain biased toward heightened arousal rather than flexible regulation between alertness and relaxation.
Physiological Mechanisms:
- Stress Response Activation: Prolonged activation of the hypothalamic-pituitary-adrenal (HPA) axis may contribute to sustained cortisol exposure, which has been associated with anxious thoughts and emotional reactivity in some individuals.
- Reduced Parasympathetic Activity: Lower vagal tone and reduced heart rate variability (HRV) have been linked in observational studies to reduced stress resilience and mood regulation.
- Neurochemical Modulation: Vagal signalling influences pathways involved in serotonin, dopamine, and GABA regulation, which play a role in emotional processing. These associations are complex and not diagnostic.
Is Your Nervous System Contributing to Chronic Fatigue, Brain Fog, or Burnout?
Ask yourself
- Is Nervous System Imbalance Contributing to Tiredness or Cognitive Fog?
Persistent tiredness, reduced concentration, and mental exhaustion are commonly reported during prolonged stress states. These symptoms may reflect difficulty transitioning into restorative nervous system states rather than a primary psychological disorder.
Physiological Mechanisms:
- Autonomic Imbalance: Sustained sympathetic activation may reduce time spent in parasympathetic recovery states, contributing to perceived tiredness.
- Neuroimmune Interaction: Chronic stress has been associated with inflammatory signalling that may influence cognitive clarity and mental stamina.
- Cortisol Rhythm Disruption: Altered daily cortisol patterns may contribute to energy fluctuations and mood variability.
Is Your Nervous System Contributing to Shortness of Breath, Dizziness, or Postural Heart Rate Abnormalities Symptoms?
Ask yourself
- Could Autonomic Regulation Influence Dizziness or Orthostatic Symptoms?
Symptoms such as dizziness, light-headedness, and heart rate changes on standing may be associated with autonomic regulation issues. These symptoms require proper medical evaluation, as they may arise from multiple cardiovascular, neurological, or metabolic causes.
Physiological Mechanisms:
- Autonomic Regulation: Altered baroreceptor and vagal signalling may influence heart rate and blood pressure responses to posture changes.
- Vascular Tone: Reduced parasympathetic activity may affect vascular constriction, contributing to pooling of blood in the lower extremities.
- Breathing Regulation: Autonomic input to respiratory muscles may influence breathing patterns during stress.
These mechanisms are not diagnostic of Postural Heart Rate Abnormalities or other symptoms and should not replace formal medical assessment.
Is Your Nervous System Impairing Digestion?
Ask yourself
- Is Nervous System Balance Affecting Digestive Comfort?
Digestive symptoms such as bloating, reflux, or irregular bowel habits are influenced by both physiological and psychological factors. The autonomic nervous system plays a role in gastrointestinal motility, secretion, and gut-brain communication.
Physiological Mechanisms:
- Vagal Influence: Parasympathetic input supports digestive motility and enzyme release. Reduced activity may contribute to delayed digestion.
- Stress-Related Blood Flow Changes: Sympathetic dominance may temporarily reduce gastrointestinal perfusion.
- Gut-Brain Interaction: Functional gastrointestinal symptoms may be influenced by altered communication between the enteric and central nervous systems.
Is Your Nervous System Contributing to Chronic Sleep Problems?
Ask yourself
- Do you have difficulty falling asleep, even when you feel exhausted?
- Do you frequently wake up during the night or struggle with restless sleep?
- Do you wake up feeling unrefreshed or experience daytime tiredness despite adequate sleep duration?
Physiological Mechanisms:
- Autonomic Imbalance: An overactive sympathetic nervous system can prevent the body from entering deep, restorative sleep, keeping it in a state of heightened alertness.
- Vagal Dysfunction: La vagus nerve plays a crucial role in regulating parasympathetic activity, which is necessary for relaxation, sleep onset, and heart rate variability (HRV) during sleep cycles.
- Cortisol and Melatonin Disruptions: Chronic stress can dysregulate the hypothalamic-pituitary-adrenal (HPA) axis, leading to elevated nighttime cortisol and reduced melatonin production, making it difficult to maintain sleep.
Autonomic dysregulation may contribute to sleep problems, fragmented sleep, and non-restorative sleep patterns, which can further impact cognitive function, emotional regulation, and overall health. Understanding the role of the vagus nerve and autonomic balance is essential for addressing persistent sleep disturbances.
Could Past Viral or Bacterial Infections Be Affecting Your Nervous System?
Ask yourself
- Could Past Infections Influence Nervous System Regulation?
Some individuals report persistent symptoms following viral or bacterial infections. Research suggests that post-infectious autonomic disturbances may occur in a subset of sick people, though mechanisms remain under investigation.
Physiological Mechanisms:
- Post-Infectious Autonomic Changes: Some infections have been associated with altered autonomic signalling in observational studies.
- Neuroimmune Interaction: Immune activation may influence nervous system regulation and neurotransmitter balance.
- Symptom Persistence: Ongoing tiredness, cognitive symptoms, or cardiovascular responses require scientific evaluation and should not be self-diagnosed.

"I wanted to know can we help our patients have an even more sustained relief from an out-of-control sympathetic nervous system. I'm happy to say so far the answer has been yes."

Dr Myro Figura
Anesthesiologist & Chief Medical Officer at HealFast
"(Nurosym) increases the rest and digest side of your nervous system by up to 61% in five minutes and it's a potent reliever for anxious states."

Dr James Gill
Associate Professor at Warwick Medical School & General Practitioner
"I found (publications) with no declared conflict of interest by Leeds University. They demonstrated reduced sympathetic nerve activity. Personally, (with Nurosym) my HRV increased from 40s to 69."

Dr Mikolaj Raszek
Researcher at Merogenomics
"Based on the evidence coming out, it looks as if these devices... appear to be helping big time in terms of Post-Viral Fatigue."

Ashley Ridout
Osteopath & Educator
"I tried this on two patients: a 45-year-old male with chronic neck pain reported better and deeper sleep... A 30-year-old female with headaches noticed improved sleep and reduced pain."

Bryan Johnson
Founder of Braintree, Project Blueprint
"HRV is a pretty significant biomarker for health. It has a clear association with age... HRV training is keeping me low key, chill and calm."
