Discover the HPA Axis Self-Assessment and learn if your stress response system needs support
Is Your Morning Cortisol Awakening Response Keeping You Wired and Anxious All Day?
Ask yourself
- Do you wake up feeling anxious or on edge, even before anything stressful happens?
- Does your heart race within minutes of waking up, pounding like you just sprinted up three flights of stairs — like you're already in "fight or flight" mode?
- Do you feel overwhelmed by the day ahead — your mind already racing through your endless to-do list before you even get out of bed?
- Does it take hours to feel calm after waking, spending your entire Saturday morning feeling wired and restless even on weekends?
If you answered yes, your hypothalamic-pituitary-adrenal (HPA) axis may be dysregulated, causing an excessive cortisol awakening response that floods your system with stress hormones the moment you open your eyes — setting a stressed tone for your entire day.
Physiological Mechanisms:
- Dysregulated cortisol awakening response (CAR): A healthy CAR involves cortisol rising 50-75% within 30 minutes of waking, then gradually declining. When dysregulated, this spike becomes a tsunami of stress hormones — surging up to 300% higher than normal — triggering anxious thoughts, rapid heart rate, and cognitive overwhelm that follows you from your bedroom to your breakfast table and beyond, persisting throughout the day
- Overactive HPA axis: Chronic stress keeps your hypothalamus hypersensitive to perceived threats, like a smoke detector with a dying battery that goes off every time you make toast — causing it to continuously signal for cortisol release even when you're just lying peacefully in bed, when no real stressor is present.
- Impaired negative feedback: Your body loses its ability to recognize when enough cortisol has been produced, like a broken thermostat that keeps pumping heat even when the house is already 85 degrees — leading to sustained elevation that maintains anxious thoughts and hypervigilance from the moment your feet hit the floor until you collapse into bed that night.
Research from the University of Leeds shows that transcutaneous auricular vagus nerve stimulation reduces cortisol response to mental stress by up to 23%. Harvard Medical School researchers found vagal tone is inversely correlated with morning cortisol levels in healthy individuals.
Is Chronic Cortisol Elevation Causing Stubborn Belly Fat That Won’t Budge?
Ask yourself
- Have you developed a "pot belly" or increased abdominal fat — that stubborn spare tire that won't budge no matter what you try — despite not changing your diet?
- Does stress eating lead to cravings for sugar and carbs, sending you straight to the pantry at 9pm searching for cookies and chips, especially around your midsection?
- Do you store fat primarily in your belly area — looking like you're smuggling a basketball under your shirt — rather than your hips or thighs?
- Have traditional diet and exercise approaches failed to reduce your abdominal fat — leaving you frustrated after months of salads and gym sessions with nothing to show for it?
Physiological Mechanisms:
- Visceral adipose tissue accumulation: Chronic cortisol elevation promotes fat storage specifically in the abdominal cavity. Your belly literally becomes a cortisol magnet — there are 4x more cortisol receptors in belly fat, making this area particularly susceptible to stress-induced weight gain that clings to you like plastic wrap.
- Insulin resistance and metabolic dysfunction: Elevated cortisol impairs glucose metabolism and increases insulin resistance, turning your body into a fat-storing machine that hoards every calorie like it's preparing for famine — creating a cascade that promotes fat storage and makes weight loss nearly impossible through diet alone no matter how perfectly you count macros or hit your step goal.
- 11β-HSD1 enzyme upregulation: Chronic stress increases the expression of 11β-HSD1 in adipose tissue, which converts inactive cortisone to active cortisol locally, essentially turning your belly fat into a cortisol factory that keeps pumping out more stress hormones 24/7 — creating a vicious cycle of increased abdominal fat accumulation that feeds on itself like a snowball rolling downhill.
Studies demonstrate that greater abdominal fat is associated with greater HPA axis reactivity. Vagus nerve stimulation helps regulate metabolic function and can support healthy cortisol rhythms essential for weight management.
Are Elevated Evening Cortisol Levels Sabotaging Your Sleep and Recovery?
Ask yourself
- Do you feel "tired but wired" at bedtime, lying there exhausted but staring at the ceiling like someone injected espresso directly into your veins — unable to wind down despite exhaustion?
- Does your mind race with worries or tomorrow's tasks when you try to sleep, replaying that awkward conversation from work or mentally rehearsing your 9am presentation over and over?
- Do you wake up between 2-4 AM with your heart racing or feeling anxious, suddenly bolt upright like someone set off a fire alarm in your bedroom?
- Do you wake up feeling unrefreshed, dragging yourself out of bed like you spent the night tossing and turning in a washing machine — like you never entered deep sleep?
Physiological Mechanisms:
- Disrupted circadian cortisol rhythm: Healthy cortisol follows a predictable pattern—high in the morning, gradually declining to lowest levels at night. Chronic stress flattens this curve, turning your natural sleep hormone into a stubborn houseguest that refuses to leave, keeping cortisol elevated when it should be low, preventing deep sleep stages that your body desperately needs to repair and restore itself.
- Sympathetic nervous system dominance: Elevated cortisol maintains sympathetic "fight or flight" activation, keeping your nervous system on high alert like a security guard who never takes a break — preventing the parasympathetic "rest and digest" state necessary for restorative sleep where your body actually does its healing work.
- Neurotransmitter disruption: High cortisol interferes with GABA production, your brain's primary calming neurotransmitter, like throwing a wrench into your brain's natural relaxation system, while increasing glutamate, an excitatory neurotransmitter that keeps your mind racing like a hamster on a wheel that won't stop spinning.
Research shows that individuals with high vagal tone have significantly lower evening cortisol levels. Vagus nerve stimulation promotes parasympathetic activation essential for healthy sleep-wake cycles.
Is Chronic Cortisol Suppressing Your Immune System and Leaving You Vulnerable?
Ask yourself
- Do you catch every cold, flu, or infection that goes around, becoming the office patient zero who gets sick every time someone sneezes within a 10-foot radius?
- Do minor cuts, scrapes, or injuries take longer than usual to heal, watching that paper cut on your finger linger for weeks like it's stuck in slow motion?
- Have you noticed increased inflammation, joint pain, or autoimmune symptoms, waking up feeling like you slept on concrete or spent the night wrestling with a brick wall?
- Do you feel like your body can't fight off infections like it used to, remembering when you could bounce back from being sick in a day, but now a simple cold knocks you out for two weeks?
Physiological Mechanisms:
- Immune suppression cascade: Chronically elevated cortisol suppresses white blood cell function, reduces antibody production, and impairs your body's ability to mount an effective immune response against pathogens, essentially turning your immune system into a security team that's constantly asleep on the job.
- Inflammatory dysfunction: While cortisol is anti-inflammatory in acute stress, chronic elevation creates a paradoxical pro-inflammatory state, like a fire department that accidentally keeps pouring gasoline instead of water on the flames — contributing to autoimmune conditions and chronic inflammatory diseases that make your body attack itself.
- Tissue repair impairment: High cortisol interferes with protein synthesis and collagen formation, sabotaging your body's natural construction crew that's supposed to rebuild and repair you overnight, slowing wound healing and tissue repair throughout the body so even the smallest injury becomes a month-long project.
Vagus nerve stimulation activates the cholinergic anti-inflammatory pathway, helping to balance immune responses and reduce excessive inflammation while supporting healthy immune function.
Are High Cortisol Levels Creating Anxious Feelings, Depressive Thoughts, and Brain Fog?
Ask yourself
- Do you feel anxious or worried even about small, manageable situations, getting your heart racing over things like checking your email or deciding what to have for lunch?
- Have you experienced increased feelings of sadness, depressive mood or hopelessness, like you're watching life through a gray filter where nothing feels enjoyable anymore?
- Do you struggle with memory problems, difficulty concentrating, or "brain fog", walking into rooms and forgetting why you're there, or reading the same paragraph three times without absorbing a single word?
- Do you feel emotionally reactive, with mood swings or irritability, snapping at your family over dirty dishes or tearing up during dog food commercials?
Physiological Mechanisms:
- Hippocampal damage: Chronic cortisol exposure actually shrinks the hippocampus, the brain region responsible for memory formation and stress regulation, literally eating away at your brain's memory center like acid on metal — creating a vicious cycle of poor stress management and cognitive decline where you lose the very brain tissue you need to handle stress properly.
- Prefrontal cortex impairment: High cortisol reduces activity in the prefrontal cortex, shutting down your brain's CEO while leaving the panic department in full control — impairing executive function, decision-making, and emotional regulation while increasing impulsivity and anxious thoughts so you react first and think later.
- Neurotransmitter depletion: Elevated cortisol disrupts serotonin, dopamine, and norepinephrine balance, draining your brain's happiness chemicals like a slow leak in your car's gas tank — contributing to anxious feelings, depressive thoughts, and cognitive dysfunction that leaves you running on empty even when you should feel good.
Scientific studies show that vagus nerve stimulation improves mood disorders by modulating brain inflammation and supporting neurotransmitter balance. Higher vagal tone is associated with better emotional regulation and stress resilience.
Is Cortisol Dysregulation Wreaking Havoc on Your Digestion and Blood Sugar?
Ask yourself
- Do you experience frequent digestive issues like bloating, acid reflux, or irritable gut, feeling like your stomach is a balloon ready to pop after every meal or rushing to the bathroom at the worst possible moments?
- Do you have blood sugar swings, energy crashes, or intense carb cravings, riding a roller coaster from wired to exhausted, desperately hunting for cookies at 3pm just to function?
- Have you developed insulin resistance or pre-diabetes symptoms, watching your doctor's concerned face as your blood work numbers creep higher each year?
- Do stressful periods immediately trigger digestive problems or appetite changes, finding yourself either stress-eating everything in sight or unable to stomach food for days when life gets overwhelming?
Physiological Mechanisms:
- Gut-brain axis disruption: Chronic cortisol impairs vagal communication between the brain and gut, severing the phone lines between your brain and digestive system like cutting a critical communication cable — reducing digestive enzyme production, slowing motility, and increasing intestinal permeability ("leaky gut") so your stomach becomes a broken-down factory that can't process food properly.
- Glucose metabolism dysfunction: Cortisol promotes gluconeogenesis and insulin resistance, turning your body into a broken thermostat that can't regulate blood sugar — causing blood sugar spikes and crashes that trigger cravings and contribute to metabolic syndrome development like a car engine that keeps flooding then stalling out.
- Microbiome imbalance: Elevated cortisol alters gut bacteria composition, wiping out your beneficial gut bacteria like antibiotics on steroids — reducing beneficial microbes and promoting inflammatory species that contribute to digestive dysfunction and systemic inflammation turning your gut into a war zone where the bad guys are winning.
Research demonstrates that vagus nerve stimulation improves gut motility, reduces inflammation, and supports healthy digestive function. Vagal tone is directly linked to better glucose regulation and metabolic health.
