As a woman, you have probably heard the idea that periods can synchronize with other women around you. Maybe you and your friends or colleagues seem to start menstruating around the same time each month, leading you to wonder if this phenomenon is real. However, the truth is that there is no scientific evidence to support the idea that periods can be synchronized.
VIYA is here to help you debunk this myth and shed light on the science behind periods.
What is Menstrual Synchrony?
Menstrual synchrony is the idea that women who spend a lot of time together, such as roommates or close friends, can have their menstrual cycles start at the same time. This theory was first proposed by psychologist Martha McClintock in 1971 and has been widely discussed ever since.
Why is the Myth Pervasive?
Despite the lack of scientific evidence, many people continue to believe in menstrual synchrony. This may be due to confirmation bias, where people notice when their periods seem to align with others and ignore times when they don’t.
Another reason for the myth’s persistence is the cultural taboo surrounding menstruation. Talking about periods is often seen as embarrassing or inappropriate, so misinformation can spread more easily.
The Science Behind Menstruation
Menstruation is controlled by a complex interplay of hormones in the body. Each woman’s menstrual cycle is unique, with variations in cycle length, duration, and flow volume. Hormonal fluctuations during the cycle can be influenced by factors such as stress, exercise, and diet.
While it is possible for two women’s cycles to align by chance, there is no scientific evidence to suggest that women’s periods can be intentionally synchronized through pheromones or other means.
Other Menstruation Myths Debunked
In addition to the myth of menstrual synchrony, there are other common misconceptions about menstruation that need to be addressed.
Myth #1: You can’t get pregnant during your period.
Fact: While the likelihood of getting pregnant during your period is lower than at other times in your cycle, it is still possible. Sperm can survive for up to five days in the female reproductive tract, so if you have a short cycle or ovulate early, you could conceive during your period.
Myth #2: PMS is all in your head.
Fact: Premenstrual syndrome (PMS) is a real condition that affects many women. Symptoms such as mood swings, bloating, and cramps are caused by hormonal changes in the body. While PMS is a normal part of the menstrual cycle, severe symptoms may be a sign of premenstrual dysphoric disorder (PMDD), a more serious condition that can be treated by a healthcare provider.
