Menstruation is a natural occurrence that almost all women cannot avoid, and there are countless legends and stories circulating about it. These include, but are not limited to, "You'll want to go on a shopping spree when you're on your period," "Your voice changes during your period," and "Your roommates will all get their periods at the same time"...
So what is the truth behind these legends? Let's take a closer look.
Does menstruation really make people want to go on a shopping spree?
It's true. And some people have actually researched it...
In 2011, Hertfordshire University in the UK published a paper stating that women may experience impulsive and inappropriate financial behavior during their menstrual cycle due to natural hormonal fluctuations…
Specifically, it refers to excessive shopping, impulsive spending, buying things and then regretting it...
Sister, you are not alone.
Is it possible to get pregnant if you have sex while you're menstruating ?
Possibly.
There are two reasons for this. First, sperm can remain active for about 5 days after intercourse, meaning that although the sperm depart during menstruation, they patiently wait for possible ovulation. Second, this is more likely to happen to women whose menstrual cycles are shorter than 28-30 days or whose periods are irregular.
Therefore, gynecologists recommend that contraception should still be used during menstruation.
Do girls who live together have the same menstrual cycle?
Actually, no.
This is a question of Harvard University versus Oxford University in 2017.
In 1971, Harvard conducted a study on 135 female college students living in dormitories, suggesting that women living together in close relationships might experience synchronized menstrual cycles. This study was published in Nature at the time.
In 2017, Oxford University conducted a larger study involving 360 female couples and found no evidence of synchronized menstrual cycles due to close relationships.
In short, coincidence played a larger role...
Does the weather affect the strength of menstruation?
meeting.
In 2010, the journal *Gynecological Endocrinology* published an article stating that sunshine and warm weather can increase ovulation frequency and shorten menstrual periods in women. According to this study, women's menstrual periods are on average 0.9 days shorter in summer than in winter.
Researchers have found that women experience more menstrual discomfort during winter, such as more severe PMS (premenstrual syndrome) or more severe menstrual cramps. They believe this may be related to decreased vitamin D levels due to insufficient sunlight and decreased thyroid function caused by low temperatures.
However, it should be noted that the researchers in this study are from Russia, where winters are winters of battle…
Does your voice change when you have your period?
Yes.
However, changes can occur not only during menstruation, but also at other points in the cycle.
This study, published in 2011, pointed out that women's voices differ during menstruation and ovulation compared to other times of the year.
Does physical exercise help relieve discomfort during menstruation?
It works for some people.
This 2009 review mentioned that appropriate physical exercise can even alleviate the symptoms of dysmenorrhea in some patients.
However, this method doesn't work for everyone. Even if it does, don't overdo it, lest it lead to tragedy...
Can menstruation trigger asthma ?
Yes. If you have asthma.
A 2016 study showed that 40% of female asthma patients experience asthma attacks or worsening symptoms during menstruation, mainly due to changes in lung capacity during this period…
Is menstruation a form of "detoxification"?
no.
We don't actually have any toxins to eliminate. Menstruation simply indicates that fertilization did not occur during that cycle.
Does menstruation affect the brain?
meeting.
Fluctuations in estrogen levels before and during menstruation can trigger changes in brain activity. Some women may experience decreased concentration, slightly slower reaction times, and more forgetfulness.
A 2008 study on the relationship between women's menstrual cycles and brain function found that women's brain activity changes at different stages of the cycle, which researchers believe is related to changes in hormone levels.
Is it possible for bleeding to occur in other parts of the body during menstruation?
Yes, but only in specific circumstances.
When endometriosis occurs in other parts of the uterus, the ectopic endometrium moves along with other endometrial tissue during menstruation, causing bleeding in that area.
For example, in 1988, the surgical department of Southern Illinois University School of Medicine reported a case of a 17-year-old girl who experienced uncontrollable bleeding during her menstrual period...
This is practically a heart-wrenching accusation against menstruation...
Endometriosis can also occur in other areas, sometimes in a very dangerous way, such as intracranial, requiring timely treatment.
After seeing all this, I feel like Aunt Flo is quite surreal...
