Why is the last day of menstruation black?

Menstruation is a physiological phenomenon that every female friend will experience. Scientific research shows that women generally live longer than men because women have this "friend" called menstruation. With the loss of blood every month, it is actually a metabolic process that helps the body detoxify. So after menstruation, many female friends will find that their skin is in the best condition during these days. Of course, if the skin is black on the last day of menstruation, it is definitely abnormal. Let us introduce the reasons why the skin is black on the last day of menstruation.

Normal menstruation is mostly dark red. When menstrual blood stays in the uterus for too long, it will turn dark red or even black. This is caused by poor circulation of menstrual blood. To deal with the blackening of menstrual blood, you must first identify the cause and then prescribe the right medicine.

1. Poor uterine contraction ability:

The shed endometrium and menstrual blood flow out of the body under the pressure of the uterus. When the uterus contracts, it compresses the menstrual blood out of the body. If the uterus's contraction ability is not good, the menstrual blood will not flow out of the body easily. If it stays in the body for a long time, it will easily turn black.

2. Retroverted uterus:

For women with a retroverted uterus, the position of the uterus causes the cervix to be higher than the uterus, so menstrual blood cannot flow out of the body all the way. Therefore, menstrual blood accumulates in the uterus for a long time and turns dark red or black.

3. Cold body:

Generally, people with cold body have slow blood circulation, and because of the cold body, the menstrual blood is exposed to the cold and coagulates, so there will be black or dark black blood clots in the menstrual blood.

Of course, in addition to the above, there are other reasons why the line may be black on the last day of menstruation, such as poor gynecological conditions or infection. If this is the problem, then you need to receive treatment. During these special days of menstruation, we should keep our mood relaxed, maintain good living habits, do proper exercise and of course get enough rest. We should all treat this good "friend" well, and treating it well is treating ourselves well.
