The Annahitah Perspective
If you’ve ever noticed that your period starts to align with your roommates, best friends, or colleagues, you’re not alone.
Nina, our Annahitah founder, has the fondest memories of living with 3 besties in her twenties, in what soon became known as the “party house”. One thing that was apparent even just after 3 months of living together was that all 4 of the girls were on their period at the same time. The phenomenon of women’s menstrual cycles syncing up is a topic that has fascinated scientists and sparked countless conversations among women.
But why does this happen? Is it just a coincidence, or is there something more at play? At Annahitah, we delve into the science and theories behind this intriguing occurrence.
The Science Behind Menstrual Synchrony
The idea that women’s menstrual cycles sync up when they spend a lot of time together is known as menstrual synchrony or the McClintock effect, named after Martha McClintock, a researcher who conducted a pivotal study on this topic in 1971. McClintock observed that women living in close quarters, such as college dormitories, often had their menstrual cycles start around the same time.
Pheromones: The Invisible Messengers
One of the leading theories behind menstrual synchrony involves pheromones - chemical signals that influence the behavior and physiology of others of the same species. It’s believed that pheromones released through sweat and other bodily secretions can affect the menstrual cycles of women who spend a lot of time together. This pheromonal communication might lead to the synchronization of their periods.
Social and Environmental Factors
Another theory suggests that shared environmental factors and lifestyles could contribute to menstrual synchrony. Women who live together or share similar routines, diets, and stress levels might experience changes in their menstrual cycles due to these common factors. For instance, stress can impact the regularity and timing of periods, so women experiencing similar stress levels could see their cycles align. 
Real-Life Examples of Period Synchrony
Roommates and Close Friends
One of the most common examples of menstrual synchrony occurs among roommates and close friends. Imagine living with your best friends during college - sharing meals, laughter, and late-night study sessions. Over time, you might notice that your periods start to align. Many women report that their menstrual cycles sync up with those they live or work closely with, lending anecdotal support to the theory.
Workplace Synchrony
Women who work together, especially in small teams or close-knit environments, often experience menstrual synchrony. Spending significant amounts of time together in shared spaces can lead to aligned cycles. This can be particularly common in female-dominated professions like nursing or teaching.
Why Synchrony Matters: A Shared Experience
While the science behind menstrual synchrony is still debated, the shared experience of synchronised periods can foster a sense of camaraderie and understanding among women. Experiencing your menstrual cycle alongside friends or coworkers can create opportunities for mutual support and empathy.
