The word "hormonal" is used dismissively and imprecisely in ways that have done women a profound disservice. The hormonal fluctuations that affect mood, cognition, energy, and physical health across the menstrual cycle, perimenopause, and menopause are real, measurable, and significant. Understanding them is not navel-gazing. It's self-knowledge with practical applications.
I used to dismiss the word "hormonal" as imprecise and dismissive. When I finally understood that hormonal fluctuations affecting mood, cognition, energy, and physical health across the menstrual cycle, perimenopause, and menopause are real, measurable, and significant, I realised this isn't navel-gazing — it's self-knowledge with practical applications.
The four phases and what they mean practically
The menstrual phase (days 1–5): oestrogen and progesterone are low. Energy is typically lower, inward focus is natural, and rest is genuinely useful rather than lazy. The follicular phase (days 6–13): oestrogen rises. Energy, cognitive sharpness, and social ease tend to increase. This is often the best phase for challenging work, creative projects, and social commitments. Ovulation (day 14 approximately): peak oestrogen and a testosterone surge. Most people feel their best. The luteal phase (days 15–28): progesterone dominates, then drops. Energy decreases, sensitivity increases, sleep can be disrupted. This is not dysfunction — it's biology, and it responds well to rest and lighter demands.
I used to expect my energy to be consistent every day. When I finally understood the four phases — menstrual with low energy and inward focus, follicular with rising energy and cognitive sharpness, ovulation with peak oestrogen and feeling best, luteal with decreased energy and increased sensitivity — I realised this isn't dysfunction, it's biology that responds well to rest and lighter demands.

Why your energy isn't consistent — and that's not failure
The expectation that women perform at the same consistent level every day is biologically misaligned with how female physiology actually works. The fluctuation in energy, mood, and capacity across the cycle is not weakness or inconsistency — it is a rhythm that, when understood and accommodated, allows you to work with your biology rather than against it.

Perimenopause: what nobody tells you
Perimenopause — the transition to menopause, which can begin in the late 30s and typically lasts four to ten years — is one of the most underdiagnosed and undertreated transitions in women's health. Brain fog, sleep disruption, mood instability, irregular periods, joint pain, and changes in skin and hair texture are all symptoms, not age-related inevitabilities to be accepted silently. A GP informed about perimenopause can offer meaningful support.

None of this requires a complete overhaul. The beauty of small, consistent improvements is that they compound over time in ways that sudden big changes never quite manage. Start with one thing. Get comfortable with it. Then add another.
The women I know who understand their hormones didn't achieve this overnight — they refined gradually: one cycle tracked, one phase accommodated, one conversation with a GP at a time. Those small changes compounded into self-knowledge with practical applications. Understanding hormones is built through consistent learning, not one dramatic transformation.
