hormonal cycles
Monthly chemical fluctuations
Hormonal cycles are recurring patterns of hormone production and release in the body.
The menstrual cycle is the most familiar example—a roughly monthly fluctuation of estrogen and progesterone that regulates ovulation and menstruation.
Other hormonal cycles operate on different timescales: cortisol follows a daily rhythm, peaking in morning and dropping at night.
Her hormonal cycle affects her energy levels throughout the month.
