Daily micro-entries, a monthly check-in, and a yearly review of trends.
The Journal
A Tool for Self-Knowledge & Insight
It began with a first wearable and a quantified sleep improvement project. Months of data later came the biological science of the menstrual cycle, and with it a micro-journal to complement the digital record. Three years, three wearables, wide reading in longevity science, and several custom editions later, this is the N of 1 Menstrual Micro-Journal — a way to build a personal healthy aging plan from both biomarker and qualitative data. Having no data or awareness of your own body is akin to driving a car without a dashboard: wearables gather the biometrics, while journaling brings awareness to how perception, experience, and daily activity intersect with them. Used over years, the journal has surfaced relationships between hormonal shifts and changes in sleep, mood, appetite, and body — and made possible small changes that improved daily quality of life.
Monthly check-in
Keeping tabs on healthy aging goals
A monthly review of weight, BMI, muscle mass, body fat, and VO2 max sits alongside the daily record. It makes visible what a few sedentary months cost in muscle, and keeps cardiovascular fitness in view as a goal rather than an afterthought. A body figure and comments field catch persistent physical issues before they trend chronic — the practical result has been getting to a professional far sooner.
The cycle at a glance
Unlocking menstrual patterns
The National Institutes of Health treat the menstrual cycle as the fifth vital sign. Seeing a full cycle on one spread turns scattered days into a pattern — and a baseline for anticipating, mitigating, and managing perimenopause when the time comes.
