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

Measuring neurotransmitters alone isn't enough. Discover how monoamine metabolites like HVA, VMA, and 5-HIAA provide deeper clinical insight into brain chemistry — and how Hormone Lab UK's at-home tests can help you understand your neurochemical health.

Your adrenal glands and cortisol levels influence almost every system in the body. This article explores how chronic stress affects adrenal function, what symptoms to look for, and how testing can help.

Cortisol is far more than a stress hormone. Learn how high and low cortisol affect your energy, weight, sleep, and immunity — and how at-home LCMS saliva testing can reveal your full daily cortisol pattern.

Stress, Cortisol, and the Hormonal Loop of Anxiety When the body perceives danger, the brain activates the hypothalamus-pituitary-adrenal (HPA) axis — an internal alarm that releases cortisol, the body’s primary stress hormone. For short-term challenges, cortisol is beneficial. It sharpens focus, boosts energy, and prepares muscles for quick action — the classic “fight or flight” response that once ensured survival. When Stress Becomes Chronic Trouble begins when stress never switches off. Prolonged cortisol exposure interferes with healthy brain function, damaging neurons in the hippocampus (responsible for memory) and the prefrontal cortex (which governs decision-making and emotional control). As these areas...

When Hormones Shape the Mind Hormones are powerful chemical messengers that quietly influence not only our bodies but also our thoughts and emotions. While neurotransmitters like serotonin and dopamine often get the spotlight for controlling mood, science now shows that hormones can have just as much impact on mental well-being. 1.

These phases involve major shifts in oestrogen and progesterone. Before menstruation: Falling oestrogen can lower serotonin, leading to irritability or sadness. After childbirth: A sudden hormone drop can trigger postpartum...
