There is a common belief that menstrual periods are synchronised with the moon cycle, known as "menstrual synchrony" or "the lunar effect."
Menstrual cycles are primarily regulated by hormonal fluctuations within an individual's body, specifically estrogen and progesterone. The average menstrual cycle lasts around 28 days, but it can vary widely among individuals, ranging from 21 to 35 days or more. This natural variation makes it unlikely for menstrual cycles to align precisely with the 29.5-day lunar cycle.
The idea of menstrual synchrony originated from a study conducted in the 1970s, which suggested that women living together in close proximity tended to have their periods around the same time. However, subsequent research has failed to replicate these findings consistently. Factors such as stress, lifestyle, and individual hormonal patterns appear to have more significant influences on menstrual cycle timing.
While some people may experience changes in their menstrual cycle due to external factors or shared social cues, there is no scientific evidence supporting a direct synchronisation with the moon cycle.
It's important to note that embracing the natural rhythms of your body and finding comfort during your menstrual period is a personal choice. Bamboo sanitary pads can be a sustainable and eco-friendly option regardless of any perceived synchronization with the moon cycle.
