Women do not sync periods

Cnet reports:

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.

A lot of ppl really believe that women synchronize cycles, and some studies claim to show it, but they don't get replicated.
