Isn\u2019t it strange when you and your best friend are on your period at the same time? Strange, but also kind of cool in a weird way? As if you\u2019ve formed some sort of special bond with each other.<\/span><\/p>\n

Or how about when your entire squad is on their period? Crazy! There has to be some logic behind this, right? Is it period syncing? Is it a coincidence? Who knows!\u00a0<\/span><\/p>\n

Well, actually: professionals and researchers know! And now you will too!\u00a0<\/span><\/p>\n

What Is Period Syncing?<\/span><\/h1>\n

Period syncing is the idea that when women live in close proximity to each other, or they spend a lot of time together, the timing of their monthly period will start to \u201csync up\u201d or align.\u00a0<\/span><\/p>\n

The first evidence to suggest that period syncing could be a \u201creal thing\u201d was in 1971 in a paper called the \u201cMcClintock study\u201d. This study was named after <\/span>Martha McClintock<\/span><\/a>, a researcher at Harvard University.<\/span><\/p>\n

The McClintock Study<\/span><\/h2>\n

McClintock began researching the topic by looking at the <\/span>menstrual cycle<\/span><\/a> of a small number of women aged 17-22 who lived in the college dorms.\u00a0<\/span><\/p>\n

She divided the women into two groups: those within close proximity of each other, such as best friends or roommates, and those who had no relationship with a select group of women.\u00a0<\/span><\/p>\n

After six months, she found that those who lived within close proximity of each other started their <\/span>period<\/span> within 3 to 7 days apart, whereas those who weren\u2019t in close proximity started their period with 5 to 15 days apart.\u00a0<\/span><\/p>\n

But, given the small scale of this study, and the fact that it is outdated, are the results still valid or reliable? Well, not really, according to other researchers.<\/span><\/p>\n

Results of Other Studies that Researched Period Syncing\u00a0<\/span><\/h2>\n

After the McClintock study, the topic quickly gained traction and other researchers got to work.\u00a0<\/span><\/p>\n
