Is Your Health Advice Based on Male Biology?

In this segment of the interview, Mona Sharma asks Alisa Vitti to explain infradian rhythms, a term that refers to biological cycles longer than a day. Vitti contrasts infradian rhythms with circadian rhythms, noting that for women the monthly menstrual cycle is a primary infradian rhythm. She describes how the shifting balance of estrogen and progesterone across the follicular, ovulatory, and luteal phases influences brain chemistry, metabolism, stress response, and immune function, effectively making a woman’s physiological state change week by week. Vitti argues that most health advice is based on circadian (day‑to‑day) patterns and therefore overlooks these monthly fluctuations, and she suggests that aligning self‑care practices with the menstrual cycle can better support women’s health.
