Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — cortisol and insomnia

Chronic stress is one of the most significant and underappreciated risk factors for heart disease and type 2 diabetes. When stress becomes persistent, cortisol — the body’s primary stress hormone — is produced in excess, disrupting insulin signalling, sex hormone balance, thyroid function, and cardiovascular health. This article explains the biological mechanisms linking stress, cortisol, and heart disease risk, the role of depression as a compounding factor, and the practical steps — including hormone testing and lifestyle changes — that can help reduce your risk.

Cortisol is your body’s primary stress hormone, produced by the adrenal glands in response to physical, mental and emotional stress. While it plays a vital role in energy metabolism, immune function and cardiovascular health, both chronically high and chronically low cortisol levels can cause significant health problems — from fatigue, weight gain and sleep disorders to burnout and adrenal exhaustion. This article explains what cortisol is, what happens when it goes wrong, and why regular testing matters.

Your adrenal glands are your body's frontline stress managers — producing cortisol, DHEA and adrenaline to keep you functioning under pressure. But when stress becomes chronic, these glands can fall out of balance, leading to fatigue, weight gain, insomnia, anxiety and more. Discover how adrenal hormones work, what imbalance looks like, and 10 evidence-based tips to restore balance.
