An Oxford professor and a period-tracking app did some research, and they say the long-lived myth is not true.
A new study examines a menstrual myth.
It’s one of those weird science “facts” that many people believe without really knowing why, like the myth that swallowed gum stays in your stomach for seven years , or that you’ll drown if you swim after eating. It’s the idea that women’s menstrual cycles will sync up with those of other women they live with or spend a lot of time with.
You’ve heard that, right? And if you’re a woman, maybe you think you’ve experienced it, in a dorm, sorority house or just a large family.
But a recent study done by Dr. Alexandra Alvergne of the University of Oxford, in conjunction with Clue, a period-tracking app , says this is just as much myth as the gum or swimming ideas.
