In this Daily Dose, Chris and Xand return to their episode on menstrual health with Dr Chi Eziefula, who flipped our perspective on the menstrual cycle, reframing it as a positive, evolutionary advantage that has enabled us to survive and thrive.

Daily Doses of expert wisdom from previous episodes will be dropping each weekday throughout January (except Tuesdays). You'll find them in the What’s Up Docs? feed on BBC Sounds, alongside all the main episodes of the podcast.
