Is "menstruation" really contagious?

If Tong has three "sisters" in the unit, the four of them always eat together, go shopping together and whisper together every day. In the past few months, Ruotong discovered a "secret"-the "period" of the four of them always came together. One pass two, two pass three, "menstruation" scramble to check in in advance, before the four menstrual period difference of many days, but now almost the same. "I've heard that menstruation is contagious." Careful women will also find that every time there is a big event, such as an important exam, work or travel, the "period" will come to "join the party." To this end, Pei Zhimei explained that when people are too nervous, excited and other emotional changes, the body's endocrine disorders, and bring a series of changes, "changes include menstruation, as well as people's blood pressure, blood sugar and other changes." She said. In order to advance or postpone menstruation, many women will drink vinegar and other methods. Pei Zhimei believes that although methods such as drinking vinegar have certain effects, they still try not to use artificial methods to change their menstruation, because the temporary effect is likely to lead to endocrine disorders male masturbation toys , thus affecting health. The same period of menstruation is related to hormone levels. Maybe every girl has experienced the infection of "period", right? It may be between classmates in the same dorm, between colleagues, between good friends, or between mother, daughter and sisters. When looking for information on the Internet, the reporter found that women are very interested in menstrual infection and hope to find this mysterious reason. The opinions on this matter are also different: "is it related to the magnetic field of yin and yang?" "it should have something to do with eating habits and living habits. People who are always together eat the same food and feel the same mood. Of course, 'period' will come together." Traditional Chinese medicine says: in fact, the infection of "menstruation" is academically called "menstrual synchronization". "it doesn't have much to do with diet, living habits, etc." Pei Zhimei said that the occurrence of menstruation is mainly related to changes in hormone levels in the body. In traditional Chinese medicine, a woman's menstruation is related to the movement and magnetic field of the moon love egg , with a period of 28 days. In today's life, it's not just the moon that affects menstruation. "there are many factors leading to the advance or postponement of menstruation, such as mood, diet, schedule, activities and so on." Western medicine said: Teng Li believes that the so-called female menstruation is contagious because they, who usually live and work together, may face the same pressure, emotions, etc., coupled with close contact with each other, will be affected by each other's hormones. It is a normal phenomenon that menstruation tends to be consistent after a long period of time, and there is no need to worry too much. Is it the sense of smell that is causing trouble? Case 1: psychologist McClintock published a study in Nature in 1971, saying that women living in the same room tend to have a closer menstrual cycle. She selected 135 resident students from a women's university as subjects and divided them into roommates, close friends and random groups. As a result, the incoming tide cycle of roommate group and close friend group approached, and the random group remained basically unchanged. She believes that pheromone is most likely the cause of this phenomenon. Case 2: in an interesting experiment conducted by in the United States in the 20th century horse cock dildo , for several months horse cock dildo , the women who took part in the experiment agreed to let another woman apply her underarm secretions under her nose every other day. As a result, the two women had quite the same menstrual cycle. This phenomenon suggests that the presence of a chemical pheromone in axillary secretions can make the menstrual cycles of two women consistent. In the interview, both experts also mentioned pheromone. The reporter learned that the so-called pheromone refers to a volatile chemical secreted by animals, which enables the same animal to transmit information between different individuals through the action of the sense of smell, resulting in behavioral or physiological changes, also known as external hormones. Is it the smell that synchronizes a woman's period? Teng Li believes that at present, there is no scientific research in the world to prove the phenomenon of approaching menstruation, although there is no scientific conclusion, and it is not known whether it is related to pheromones. But what is certain is that the phenomenon of menstrual convergence exists.
