Biology Beyond the Obvious is a 9-part blog series reframing overlooked systems—fascia, mitochondria, gut, skin, water, senses—through the nervous system lens.
Late perimenopause: cycles fading to 50, 60, 90 days, then nothing for months, then a ghost bleed that throws everything into question. You’re not post-menopausal. You’re in rehearsal. The body is shifting from pulse-based rhythm to field-based regulation, and the disorientation is temporal — your internal clock is learning to keep time without the drumbeat.
Menstrual blood color in perimenopause isn’t ‘just hormones’ — it’s a monthly terrain report. Dark clots, pale flow, and irregular timing reveal circulation, detoxification, and endocrine rhythm. Your bleed isn’t misbehaving; it’s mirroring throughput.
The reset fantasy: that moment when every cleanse, supplement stack, or perfect diet ‘stops working.’ You don’t need another reset — you need rhythm. Your metabolism isn’t stubborn; it’s braced. Every cleanse fails when the nervous system is still in lockdown.
