It said that women who live together begin to menstruate on the same day every month. Period Syncing is also known as menstrual synchrony. It hangs on the theory that when you come with physical contact with another person who menstruates.
There is a possibility that your pheromones influence each other so that in due course, your monthly cycle line up.
This process is the McClintock Effect.
The design of period syncing has been passed down from mothers to their daughters. It is consider in hostels and women restroom for centuries.
But the scientific group goes ahead to take the idea sternly when a researcher named Martha McClintock. To organize a study of 135 college women living in a dorm together to see if their menstrual cycle aligned.
In the year 2006, a new study and review of the writing made an allegation that â€œwomen do not sync their menstrual cycle.â€ The study collected data from 186 women living in groups in dorm China.
The study concluded that any period syncing that appeared to occur within the realm of mathematical coincidence.
Oxford University conducted another substantial study.
In the study, the period-tracking app company clue was the most significant blow yet to the theory of period syncing.
Data collected from 1500 people illustrate that its unlikely that women play havoc with each otherâ€™s menstrual cycle by being proximity to one another.
A small study in 2017 keeps the idea of Period Syncing is functioning by pointing out that 44% of participants that were living with other women experienced period synchrony.
Â Why is Period Synchronicity hard to manifest?
Period Syncing is controversial because we are not sure about the pheromones. On which the theory pivot can influence when your periods start.
Pheromones are chemical signals that we transmit to other humans around us. They mark attraction, fertility, and sexual arousal, among other things.
In the end, the study which was conducted by Martha didnâ€™t test the other elements. The elements include women ovulated, but it did track when the monthly bleeding began.
Martha culminates that the womenâ€™s period was indeed syncing up.
Menstrual synchrony might often emerge due to the laws of probability more than anything else.
