Definition
Menstrual cycles are a coordinated hormonal sequence with real effects on mood, cognition, sleep, and physiology across the roughly 28-day cycle. Cycle-related symptoms are legitimate physiology.
Why it matters
Cycle-related complaints have been minimized in medicine for decades. Taking them seriously is basic clinical dignity.
The Science
Estradiol and progesterone fluctuate predictably. Some individuals experience PMDD — severe mood shifts in the luteal phase — with real neurobiological signatures and effective treatments.
The NSI Perspective
NSI treats menstrual physiology as real biology deserving real care.
Clinical Implications
Cycle tracking, PMDD screening, and appropriate treatment are legitimate care.
Practical Application
If your body follows a cycle, tracking it is not fussy — it is data.
