According to research, in the era without sanitary napkins, women experienced a long process of evolution in physical hygiene.

In primitive society, women had no measures to deal with menstruation. They only used dry grass or leaves to apply blood stains.
In the period of slave society, humans gradually became civilized. At this time, women used bark or animal skins to sew underwear to cover their shame. When menstruation came, some dry matter was placed on the pad to absorb dirty blood, and they learned to wash their vulva with clean water.

In feudal society, mankind gradually invented silk and weaving, and gradually abandoned primitive things such as animal skins and bark. Clothes became the greatest symbol of civilization.
At this time, before papermaking was invented, women used plant ash into small cloth strips, tied with thin threads at both ends to their waists, which became a so-called sanitary belt. The number of replacements is determined according to the degree of wealth.
Replace the sanitary belt, discard the stuff that is full of dirt, and wash the sanitary belt with water and saponaria. Use it after air-drying. When in a hurry, use fire to dry. At this time, it was basically carried out under private conditions.
Some wealthy families will prepare clean cotton and other items for women as materials for making sanitary belts. But because new cotton is not easy to absorb water, many women are more receptive to plant ash.

After humans invented papermaking, things such as straw paper that easily absorb moisture came in handy. Straw paper is used directly or sandwiched in a sanitary belt. Some wealthy people use white paper for rituals to make sanitary belts, because besides its toughness, this white paper is also whiter and relatively hygienic. However, due to the high price of this paper, not all families can consume it.

In terms of women's physical hygiene, only wealthy families used to attract attention. Women have always been in a relatively low position in social life. Many people and girls find their own solutions to their menstrual cramps. Some girls use cotton and other items as plugs and stuff them into the vagina in an attempt to prevent the blood from flowing out, while some girls never use sanitary belts for life.
In ancient times, women got married and had children relatively early, and after their menarche was basically low, some people had already said that they would marry a wife early, and they would not have menstruation during pregnancy and childbirth. This is the best thing for women with poor family conditions. Happy moments. There was no family planning in ancient times, so women basically gave birth to one after another. When they were unable to have children, their menstruation stopped.

It was very traditional in ancient times. There were few sanitary belts sold in the market, that is, they were only sold by salesmen or some rouge gouache stores. So basically the sanitary belts used by women are made by themselves. Women will pass on old and small, and pass on small. Learn from each other the techniques and techniques of making sanitary belts. Some women with dexterity will embroider patterns on the sanitary belt.
In terms of color, blue and black are the fabrics women prefer to use for sanitary belts. There are also Shaoshuren using white cloth that has not been dyed. The red fabric is basically not used. In imperial families, yellow was occasionally used, but black and blue were basically preferred.
The frequency of replacement and the number of sanitary belts used by women are determined according to the family conditions. Some women stay with a sanitary belt for life.

Due to sanitary conditions and heavy labor, many women suffer from serious gynecological diseases. In addition, ancient men have little knowledge of hygiene, so they often bring many germs to women. Some men who cherish fragrant and pity jade will actively purchase materials for their women to make sanitary belts, while some men take pleasure in collecting female sanitary belts. But most men think that a woman's sanitary belt is a symbol of evil and filth. Very taboo to see a woman's sanitary belt.

With the development of papermaking technology, in the modern civilization period, sanitary napkins gradually entered the family, and women really began to enjoy the fun of being a woman. Women's physical hygiene has been revolutionized.
Today's sanitary napkins have more and more tricks. People not only pursue comfort and practicality, but also environmental protection is just the foundation, and they also pursue fun. Some sanitary napkins are also printed with provocative and warning patterns, and some also have pictures of male genitalia. In short, they are strange.

Women's social status has improved, and businesses are increasingly looking at women's consumption. Love sanitary napkins will be purchased by men and given to lovers.
Sanitary napkins are derived from terms such as "bread" and "hamburger". In the future social development, the daily care of female vulva is far more concerned by women than the troubles caused by menstruation. Various products for sterilization and personal care of female vulva will also emerge in endlessly.
