Probably because menstruation is related to female fertility, so many women are very sensitive to menstruation, as long as something is not right, they will be very nervous and pay more attention to menstrual care. Let's take a look at eight issues that women are more concerned about menstrual health care.

Although the "period" meets every month, but every time we are not happy, she is like the "most familiar stranger" in life. So we specially answered 8 questions about "period" this time, and the next time we met her, we would no longer be unhappy!

1. Why can't you drink green tea and coffee during your period?

We often think that during the period, drinking a cup of hot tea may relieve the uncomfortable feeling, but not all hot drinks can relieve the discomfort.

For example, tea, coffee and other drinks contain caffeine has an exciting stimulating effect, but will make dysmenorrhea, waist pain and other serious feelings.

At the same time, during the period of "menstruation", iron, an important element in the synthesis of erythroprotein, will also be lost, and the tannic acid in tea will affect the absorption of iron molecules.

2. Why do blood clots sometimes appear

Usually in the first few days of "menstruation", this phenomenon occurs more frequently, and some girls only come once in a few months, so the uterine mucosa is thicker and more prone to blood clots.

Generally speaking, there is no need to panic about the appearance of blood clots, unless it is bigger than an one-dollar coin (about 24.26mm directly), you should see a gynecologist.

During the period of "menstruation", pay attention to keep warm, avoid cold, cold, raw and exciting food, avoid strenuous exercise and take more rest, which can reduce the discomfort caused by blood clots.

3. If you are too fat or too thin, will your menstruation become chaotic?

Being too fat or too thin can disrupt the menstrual period. The most common cause of obesity is that long-term intake of food produces more calories than the body needs, so the remaining calories are converted into fat and stored in the body.

The aromatase activity in the adipose stromal cells is higher than the normal level, which will increase the amount of androgen into estrogen in the body to 2-5 times the normal body weight, causing disorder in the physiological period.

And too thin, too little fat in the body will reduce the synthesis and secretion of estrogen, affecting the normal activities of the endocrine system.

Experts point out that girls with a height of 1.65cm must weigh at least 49 kilograms and 17% body fat in order to keep their menstruation normal. So don't affect your health in order to lose weight.

4. Why do you get pimples before every "period"?

The skin condition of many girls will change with the 28-day physiological period, and the physiological period is a week in advance, which is the time when the skin is most prone to conditions, because the level of estrogen drops, lutein and androgen rise, and endocrine disorders make the skin prone to oil. it's easy to get pimples.

At this time, you can put the vitamin E in the vitamin E capsule on the acne before going to bed and wash it the next day. Or use pearl powder as a mask to balance endocrine and detoxification.

5. Why did the "period" suddenly come back when having sex at the end of the menstrual period

This is because the best part of sex causes the body to release chemicals, causing the vagina to contract. When the "period" comes, the body will also produce these chemicals to help the uterine mucosa fall off.

So at the end of the menstrual period, if you get the best part of the sex, although you feel that the physiological period is over, the vagina will still make the residual menstrual blood wash out of the body, so don't worry.

6. You can't sing with your period.

Don't lie to you, if you use your voice excessively in the early period of your period, it will have a bad effect on your voice! Because the tone of the voice of girls is higher than that of boys, and some scholars regard voice as the secondary sexual characteristic of girls, so the voice of girls, like the menstrual period, will also be affected by estrogen.

The physiological period is affected by the changes of estrogen in the body, which will make the capillaries of the vocal cords congested and the blood vessel wall more fragile than usual. At this time, if you let the vocal cords in a state of fatigue, it will make the voice become hoarse, and even cause vocal cord bleeding.

So try not to sing with your period, especially don't sing high-pitched songs in the early stage of your physiology.

7. Why do you feel bloated before your period

Before each menstrual period, you can often feel a feeling of flatulence in the stomach. This is because before the physiological period, the level of progesterone in the body is higher, the digestion rate slows down, and when the food cannot be digested as expected, you will feel flatulence and even constipation.

However, this discomfort will gradually disappear after menstruation, and flavonoid levels will return to normal. In the meantime, avoid eating foods that contain fiber, such as celery, which can relieve discomfort.

Is it normal for the blood to be dark brown after the menstrual period?

Don't worry, because this is the last menstrual blood that comes out of the body. But if it happens a few days before the menstrual period, it will attract attention. It may be a sign of endometrial displacement and may affect fertility. You should see a doctor as soon as possible.
