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

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.

This article explains the biochemical distinction between the two, how they act as neurosteroids, and why measuring DHEA-S is the gold standard for assessing adrenocortical activity.
