Chronic Anxiety & Insomnia
When Stress Hormones Stop Following a Natural Rhythm
Many people living with chronic anxiety and insomnia are told the same thing:
“Your blood tests are normal.”
“Try meditation.”
“Reduce stress.”
But when your nervous system feels constantly activated — when you feel wired, restless, unable to sleep properly, or anxious for no clear reason — the problem often lies deeper than mindset or willpower.
In many cases, it comes down to cortisol rhythm and the metabolic environment that regulates it.
At How It Heals in Brisbane, we investigate the biochemical patterns that can drive persistent anxiety, sleep disruption, and stress intolerance.
Because hormones must do more than sit “in range”.
They must signal, rise, fall, and clear properly throughout the day.
The Pattern We Often See
Exhausted, but Wired
Many clients arrive describing a similar pattern:
• Anxiety that appears without an obvious trigger
• Feeling constantly “on edge” or overstimulated
• Difficulty falling asleep despite exhaustion
• Waking between 2–4am with a racing mind
• Poor sleep quality even after long nights in bed
• A heavy reliance on caffeine to function
• Brain fog and poor concentration
• Feeling calm at night but unable to switch off
Often this reflects disruption in cortisol signalling — the hormone responsible for regulating our daily stress rhythm.
Normally cortisol should:
• rise in the morning
• support energy and focus during the day
• gradually fall in the evening
• remain low during sleep
When that rhythm becomes flattened, delayed, or reversed, the nervous system can become stuck in a state of persistent alertness.
Why Standard Testing Often Misses This
Most conventional testing measures cortisol once, usually through a morning blood test.
But cortisol is not static.
It follows a dynamic circadian rhythm across the day.
This means a single blood test can appear within the normal cortisol range while the daily rhythm itself is disrupted.
This is why we often investigate cortisol using salivary cortisol testing instead.
Cortisol Saliva Testing
A salivary cortisol test measures cortisol levels at multiple points throughout the day.
This allows us to observe patterns such as:
01
Low morning
cortisol
Difficuly waking up. Morning fatigue that passes as the day progresses.
03
Flattened cortisol rhythm
Chronically fatigued. Low motivation. Exhausted by the smallest thing.
02
Elevated evening cortisol
Physically tired in the evening but mentally wired. Difficulty winding down to sleep.
04
Overactive stress signalling
Consistently maxed out. Always in "stress" mode. Very little tolerance.
This type of cortisol spit test helps us understand how your body is responding to stress across a full day — not just a single moment in time.
For people experiencing chronic anxiety, insomnia, or persistent fatigue, this often provides insight that standard testing cannot.
When Cortisol Is High
Or Simply Dysregulated
When cortisol remains elevated or poorly regulated, people may experience:
• persistent anxiety
• poor sleep quality
• racing thoughts at night
• abdominal weight gain
• irritability and poor stress tolerance
• sugar cravings and energy crashes
• hormone disruption
• brain fog and cognitive fatigue
In more severe cases, excessive cortisol patterns can overlap with conditions like Cushing’s syndrome, though most individuals experience subtler forms of stress hormone dysregulation.
Looking Beyond Cortisol
The Metabolic Environment
At How It Heals, we rarely look at cortisol in isolation.
Stress hormone patterns are influenced by many aspects of the body’s metabolic terrain, including:
• nutrient status
• mitochondrial energy production
• gut microbiome signalling
• detoxification pathways
• inflammation and oxidative stress
When these systems are disrupted, the body may struggle to regulate cortisol properly.
This is why addressing chronic anxiety and insomnia often requires looking upstream, not just suppressing symptoms.
Organic Acids Test (OAT)
Fatigue, brain fog, and poor stress tolerance often reflect problems in cellular energy and gut metabolism.
The Organic Acids Test maps markers linked to mitochondrial function, neurotransmitters, microbial overgrowth, and nutrient pathways.
Salivary Cortisol Testing
A salivary cortisol test helps map cortisol patterns across the day to understand stress hormone signalling.
Unlike conventional cortisol testing, this test shows your the pattern of your stress and the precursors/pathways involved for better treatment insights.
Hair Tissue Mineral Analysis (HTMA)
Mineral balance plays a key role in nervous system regulation and stress resilience.
HTMA can reveal mineral imbalances and metabolic patterns that influence hormone regulation. It also shows heavy metal burden, a silent contributer to chronic stress & inflammation.
Our Core Chronic Fatigue Investigations
A Different Way To Approach Anxiety & Sleep
Most conventional approaches treat anxiety and insomnia as isolated symptoms.
But from a terrain perspective, these patterns often reflect deeper biological signals:
The nervous system responding to a body under metabolic stress.
By investigating cortisol rhythm, metabolic function, and biochemical balance, we aim to identify why the system became dysregulated in the first place.
This allows us to work toward restoring:
• stress resilience
• stable energy
• deeper sleep cycles
• balanced hormone signalling
