How Stress Affects Your Cycle
Most of us have experienced it: a period that arrives late after a demanding month, a cycle that disappears during a stressful year or a sudden wave of PMS in a particularly chaotic stretch. This is not imagination as it is one of the clearest examples of how deeply the stress response and the reproductive system are linked.
The Four Phases of Your Menstrual Cycle
For something that shapes so much of our lives, the menstrual cycle is remarkably under-taught. Most of us left school knowing that a period happens roughly once a month, and very little else. But your cycle is not a single event; it is a four-phase hormonal rhythm that influences your energy, mood, sleep, metabolism, skin, and cognition across the entire month.
Understanding PCOS
Polycystic ovary syndrome (PCOS) is the most common endocrine condition affecting women of reproductive age, with global prevalence estimated at 6 to 13 percent. Yet up to 70 percent of those affected remain undiagnosed. Its name is also misleading: PCOS is not primarily about cysts and you do not need to have "polycystic" ovaries to have the condition.
Your Thyroid and Your Cycle
The thyroid is a small, butterfly-shaped gland at the base of the neck and it has a vastly outsized influence on almost every system in the body, including the menstrual cycle. Women are up to ten times more likely than men to experience thyroid dysfunction and yet it remains one of the most under-recognised drivers of cycle irregularity, fertility issues as well as persistent fatigue.
PMS vs PMDD: Knowing the Difference
For generations, the days before a period have been brushed off as moodiness, irritability, or something to simply "get through". But what happens in the luteal phase is real, it is physiological, and in some cases it is disabling. Understanding where ordinary premenstrual changes end and a medical condition begins is essential.
