Women synchronize their periods

Up to 80% of all women believe that it is true, but it is not, according to a study carried out in 2017 by scientists from the University of Oxford. They observed the periods of 360 pairs of women, who either lived together or spent much of their time together. The results showed that the periods were not synchronised. Instead, the opposite: there was a slight tendency towards the women’s periods moving further apart over time.
