Why is it that women who are close get their menstrual cycle at the same time?

Answer 1

Certain women are menstrual pacesetters. Their sweat contains pheromones (which are scents that we humans can not consciously detect, but which send us signals nonetheless) that tell other women's bodies to cycle in synchronization with them.

They found this out, btw, by keeping absorbent pads under the arms of such women for a day, and then rubbing the pads on the upper lips of other women. Yummy. But it worked... about 80% of the women synchronized their cycles with their pacesetters.

As to why it works? Harder to say. It could be something like in rats, where if you have a bunch of female rats they all reproduce at the same time, so that the babies are all the same age and don't compete with one another. Thus if one human mom loses her milk, or dies or something, the other moms with babies of the same age are able to pick up the slack. Or it could be something totally other. I don't mess with evolutionary psychology.

Answer 6

There are hormones called pheromones that women emit and causes us to synchronize when we spend large amounts of time together.
