Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — Stress

GABA is the brain's primary inhibitory neurotransmitter — and its balance is critical for restful sleep. This article explores how both low and high GABA levels can disrupt sleep, and why addressing the adrenal stress response is often the key to resolving GABA-related sleep problems.

Stress is not just a feeling — it triggers a cascade of neurochemical signals that activate the HPA axis. This article explores how neurotransmitters like serotonin, dopamine, GABA, and norepinephrine interact with the stress response, and why mood disorders such as anxiety and depression are so closely linked to HPA axis dysfunction.

An estimated 80% of adults will experience some level of adrenal fatigue in their lifetime — yet it remains one of the most under-diagnosed conditions in modern medicine. When the adrenal glands are chronically overtaxed, cortisol output drops, leaving the body unable to manage stress, stabilise blood sugar or mount immune defences. This article explores the symptoms, causes and what you can do to identify and address adrenal fatigue through targeted hormone testing.

Cortisol can be measured in saliva, blood and urine — but each method tells a different story. Saliva reflects bioavailable cortisol, blood measures total output, and dried urine captures the full circadian pattern. This article explains the clinical differences and helps you choose the right test.

Exercise is one of the most powerful tools we have for preventing and treating depression — yet its neurochemical effects are still underappreciated. From boosting serotonin and dopamine to increasing GABA through yoga, physical activity reshapes the brain in ways that rival pharmaceutical interventions. This article explores the science behind exercise and mood, and what it means for your neurotransmitter health.
