Rumors
I'm sure you've seen such a statement on many marketing accounts:Women's menstruation is actually periodically excreting toxins from the body, so menstrual blood is waste blood. If you don't have menstruation, it means that you may be sick because the body has lost its normal detoxification function.
This statement is also the consensus of many people, in some remote villages, women in the menstrual period are restricted from participating in various important activities, not because it is inconvenient, but because the waste blood discharged from menstruation will cause disaster.
But what is the actual situation?Is menstruation really detoxifying?Is menstrual blood really toxin-filled waste blood?

How does menstrual blood come about?
As early as the 50s of the last century, some people put forward the theory of "menstrual toxin", but the process of asserting is extremely arbitrary: scientists at Harvard University injected women's menstrual blood into animals, and after a while, some animals died, so they deduced that menstrual blood had toxins.
Some scholars have pointed out that the lack of comparative evidence in this experiment is likely due to the fact that the blood samples carried bacteria and other contaminants. On top of that, animals also have blood types, and compared to humans, the species are complex and unstable. For example, dogs also have 8-13 blood types, and if they are transfused incorrectly, they will also cause hemolysis problems.
Actually, menstrual blood is far less terrible.
From puberty, a woman's reproductive system matures. During the menstrual cycle, the ovaries release eggs and secrete enough estrogen and progesterone to make the endometrium thinner and thicker, creating a fertile soil for future fertilized eggs.
After the egg is released, if it is combined with the sperm, it will come to the endometrium to give birth to a fertilized egg. But if the egg is not fertilizedThe endometrium, which has thickened but is useless, will die and fall off, causing bleeding.
This blood is discharged from the uterine cavity and then flows out**, which is the origin of menstrual blood. Menstrual blood consists of three-quarters arterial blood and one-quarter venous blood, and these blood do not flow in a small area alone, just like the rest of the body's bloodSo,The idea that menstrual blood is waste blood is simply nonsense.
At the same time,Menstruation also has nothing to do with detoxificationAfter all, along with menstrual blood, there are also small pieces of flesh shed by the endometrium, which is precisely where the fertilized egg is conceived, and it would be unreasonable to say that this place is poisonous.

If you don't have a period, it's unhealthy
On many platforms,".Good qi and blood means heavy menstrual flow, and at the same time, it means good healthThe argument is rampant.
In fact,There is no scientific reason for this. After all, we have argued that menstruation is not the same as detoxification, and menstrual blood is not waste blood, but healthy blood in the human bodyHeavy menstrual bleeding can lead to anemia and weakened immunity.
On the contrary,Heavy menstrual bleeding may be the result of problems such as uterine fibroids or endometrial polyps, as well as abnormal blood clotting mechanismsIt leads to increased menstruation, and you need to pay careful attention and find a doctor to determine the situation before you can prescribe the right medicine.
The amount of blood in menstruation also varies from person to personThe usual flow rate is between 50 ml and 80 ml. The unified standard of our country and the International Federation of Obstetrics and Gynecology (FIGO) is that a menstrual flow of less than 5ml is oligomenorrhagia.
There is also an argument on the Internet:A 7-day menstrual period is much better than a 3-day menstrual period. Some people believe that short menstruation means a long cycle and a relatively large number of ovulation times, which means that women who only have 3 days of menstruation have more eggs, and the eggs are limited, so short menstruation will cause early menopause and even premature aging.
Actually,There is no necessary correlation between the above inferences and conclusions, and menstruation is normal as long as it is 2-8 days.
Although a woman has a limited number of eggs in her lifetime, the number of ovulations per person is not fixed, it is related to the cell aggregates in the ovaries - follicles. Every month, the ovaries of healthy women will be adjusted according to the number of follicles, and 3-11 follicles will be selected to develop, and each follicle will have an oocyte, that is, the prototype of the egg. After growth, the best-developed follicle will release the egg, and the rest will naturally degenerate.

What is really important to note is that in addition to the length of the menstrual period and the size of the flow, there is actually the menstrual cycle.
In general,The menstrual cycle is around 28 days(calculated at the interval between the previous menstrual period and the first bleeding of the next menstrual period).As long as it is advanced or postponed for less than a week, it is within the regular range.
If the cycle is too short, less than 21 days, there may be a problem with the secretionFor example, ovulation disorder or luteal insufficiency, if the cycle is too long, more than 35 days, it may be a problem with the ovaries, or there may be premature ovarian failure, polycystic ovary syndrome and other diseases.

Can you hold back your menstruation?
A few days ago, the topic of "high-speed rail selling sanitary napkins" appeared on the hot search, and netizens praised it one after another, and women's physiological demands were finally seen, which is obviously a big progress. However, there are also many people who claim to be women, saying that sanitary napkins are not a necessity, because in the past experience of "them", menstruation seems to be "tolerable" like defecation and defecation.
Don't speculate on the intention of the above remarks, after all, the world is so big, there may indeed be an exception. But to emphasize one thing, for every anatomically normal woman,Menstruation is not the same as, urine, and fart, you can endure it if you want to.
The reason why people can resist the desire to excrete on important occasions or when they can't find the bathroom for a while is that the excretion channels of urine - the urethra and the excretion channels of feces and farts - have sphincters.
The sphincter is a type of muscle, which belongs to the ring muscle, which is commonly found in the digestive tract and urinary system of the human body, and maintains the normal function of the human body through contraction and relaxation.
In simple terms, it acts like a valve that can be controlled by humans and opens as needed. Like patients with incontinence, in fact, the sphincter loses its normal function due to various reasons and does not listen to people.
And when women menstruate,Menstrual blood is discharged from the sphincter, which is not a muscleThat is to say,There is no way to close the "valve" at will"of. It's like a cut on the arm, and the blood will flow out naturally, not depending on the will of the person. If you can hold back the bleeding like urine, it can solve a medical problem.
However, I would also like to remind readers that although it can be tolerated, it is better to let it excrete freely until the moment of last resort. Holding urine and feces for a long time will cause great harm to the body.
Urine is actually produced by the kidneys constantly filtering waste products from the blood, and along with the ureters, it eventually collects in the bladder. However, if you hold urine for a long time, the bladder will lose its elasticity and cause it to be unclean during urination. In addition, if the urine is squeezed too much and exceeds the maximum carrying capacity of the bladder, it will become congested in the ureters, allowing the urine to return to the kidneys, causing fluid accumulation and disrupting the original function.
Similarly, the stool that has been held back from the rectum to its previous link: the sigmoid colon. In this process, feces produce large amounts of harmful substances such as ammonia and sulfide in the body, which are absorbed by the organs along with water. Eventually, it induces a variety of risk diseases.
In view of this, people who have not had menstruation should not easily teach women to hold their menstruation, first, this is too idealistic, from a physiological point of view, they can't hold it at all, and second, "holding it" is not a healthy practice.

Menstruation-related topics have sparked discussions on the Internet many times, and many people believe that menstruation already existed before the invention of sanitary napkins, and the older generation of women have adapted to it, so why can't the new generation of women?
But in fact, the older generation of women did not adapt, but silently endured the pain under the pressure of the environment. Older generations of women will use plant ash or cotton cloth that is used many times as sanitary napkins, which is actually very harmful to their health.
To this day, many women still struggle with menstruation, a normal physiological phenomenon.
According to a 2020 survey by the International Federation of Obstetrics and Gynecology, about 500 million women worldwide are menstrual poor and cannot afford proper sanitary napkins.
Menstruation is only the result, but its ** is the basis for the survival of the original human form. Every normal person who is not born from IVF** but has been conceived in the womb for ten months should face up to and respect its existence.
Female readers can ** to your male friends around you, after all, they do not empathize, and rarely take the initiative to understand, male readers can search for more information on the basis of this article if they are interested, a small change, may bring unexpected good deeds to the gender of half of the world's population.
Change from now on.
Conclusion
1.Menstruation is only a manifestation of the normal functioning of the female reproductive system, which is a normal physiological phenomenon, not detoxification.
2.Menstrual blood is not much different from blood from other parts of the body, and it is nonsense to contain toxins.
3.The menstrual cycle, the length of menstrual periods, and the size of menstrual blood flow vary from person to person, and as long as they are within a fixed range, they are considered normal, and there is no necessary correlation with early menopause and premature aging.
4.Menstrual blood is from the ** and cannot be "tolerated" like urine and feces.
