Why is it that when a group of women are together for an extended time, their period develop at alike time?
Answers: i used to know someone surrounded by a family beside a mom and 4 girls - i dont envy the dad! i dont think they know why it happen but it does - on one hand you hold 3 weeks or so of piece but then you could enjoy one HELLISH week or so - maybe be at a confrence that week of every month!
really? :O It have to do with hormones. Men could be contained by danger. Yes, women that work together surrounded by offices and other places fundamentally often start to cycle at one and the same time. I know some people that breed beagles and they maintain the females close to each other for like reason. When they start to enjoy their young, it is usually in a few days of each other.
LOL. I lived surrounded by a dorm in college...man in attendance were some catty fight! Can't say I miss it when the integral floor had PMS! It's something roughly the hormones just floating around contained by the air or something. Feramones mixing
This may not even be true.
"The conception dates at smallest to 1971, when Dr. Martha K. McClintock, an experimental psychologist, published a study showing that the menstrual cycles of women living in a college dormitory tend to synchronize over time. Dr. McClintock and other scientists suggested it might have something to do beside pheromones, chemicals that send messages by smell.
Over the years, studies own added weight to the findings, suggesting that it occur in other animals, and proposed a range of evolutionary reasons for it. But nearby is considerable debate over whether the phenomenon really exists, and many studies hold produced findings suggesting it does not. . . .
A study published last year within the journal Human Nature looked at 186 women living within dorms for a full year and found no evidence for synchrony. The authors also reviewed the original 1971 study and argued that its findings be due to chance."
