As the first feature of every woman, I believe that no female friend will care. Small and flat breasts have always been the trouble of many women. Although with the development of modern medical beauty technology, surgery can be chosen to change the size of the chest, but since it is surgery, there will be some risks, and durability is also a very important issue.
According to the 20021census, the population of school-age women (20-34 years old) in China is about 65.438+0.4 billion, including 26.6 million A cups and 82.6 million B cups. The crowd behind this contains huge market energy. According to "Report on Market Demand Prospect of Breast Enhancement Industry in 20 18-2024", in 20 12, the breast enhancement market in China was 2.736 billion yuan, and by 20 15, it had soared to 4.5865438 billion yuan, with a cumulative increase of 6.743%.
Small breasts of women are all caused by these reasons.
1, excessive pressure
If women are in a state of excessive pressure and depression for a long time, it is easy to cause breast diseases, and they are often angry and nervous, which will not only cause breast pain, lumps and hyperplasia, but also make some benign diseases slowly deteriorate and eventually evolve into serious diseases. For adolescent girls whose bodies are developing rapidly, it will affect the development of breasts.
In fact, girls usually enter puberty at the age of 10 to 12. At first, there will be induration under the nipple, and then it will gradually expand, and the areola will gradually start to protrude and expand. When the nipple grows up, the whole breast shape comes out. It takes about four to five years from development to basic stereotypes. Breast development will be affected by endocrine hormones, such as gonadotropin and prolactin secreted by pituitary gland, estrogen and progesterone secreted by ovary, hormones secreted by adrenal gland and thyroid gland, etc. With these things, breasts can be fully developed. Moreover, the development of breasts must be inseparable from factors such as diet and nutrition.
overpressure
But for today's children, as long as the diet is balanced, there is basically no malnutrition, but emotion, sleep, exercise and so on. Will affect this complex endocrine system. Moreover, adolescent girls are usually in a state of mental stress caused by academic pressure for a long time, which is also one of the main reasons that mainly affect the endocrine function of adolescent girls. Compared with boys, in fact, girls' learning pressure will be relatively greater. A survey of more than 800 senior high school students in/kloc-0 by the Youth Research Center shows that girls spend more time on homework and study than boys on average every day. However, if the study pressure is too high, the thyroid gland will get excited, which will eventually lead to an increase in cortisol and accelerate fat burning, and the chest is the easiest to lose fat, so it is not difficult to imagine becoming a "Princess Taiping".
2, lack of sleep
I believe everyone knows the harm of lack of sleep, but everyone ignores it, but it is very harmful to adolescent girls, because the period of deep sleep at night is the peak of various hormones secretion in the body, and once lack of sleep will seriously affect endocrine function, which in turn affects the development of adolescence.
