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. The Emotional Swing of Oestrogen and Progesterone Women often experience emotional changes before menstruation, after childbirth, or during menopause. 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...

A Recipe for Beating (and Preventing) Breast Cancer The latest research on natural progesterone and breast cancer clearly indicates how important it is for women to maintain healthy, normal levels of progesterone that are in proper balance with oestrogen. Doing so could not only increase many women’s chances of recovering from breast cancer — as the latest research indicates — but could also help them to avoid getting breast cancer in the first place. As Dr. John Lee and Dr. David Zava point out in their book, hormonal imbalances have reached epidemic proportions in most developed countries over the last...

Cortisol should increase around 50% in the first 30 minutes on awakening, then start to progressively drop the remainder of the day. Three, rather than one, early morning collections are what is needed to accurately assess the CAR: one immediately on waking, one 30 minutes later, and another at 1 hour. Diurnal Rhythm Assessment Thirty minutes after awakening from a good night’s sleep, cortisol levels are at the highest they’ll be all day. Following the morning peak, cortisol levels then fall to less than half that peak level by noon. They continue to drop to very low levels at night...

I remember the uncertain winter of my entrance into perimenopause so well. It began in my late 40s, with hot flashes that came on like heat waves every half hour. In the dead of winter, I found myself flinging open windows to let in the freezing air; I soon found out that having hot flashes in winter was nothing like having them in summer, when the added heat and humidity made them feel more like mini-meltdowns. How to Cool Down Without Melting Down Perimenopause is a hormonally challenged transition during which the ovaries gradually begin to make less oestrogen and...
