Menstruation towel is just needed by girls every month. Every year, Double Eleven is the top1 of the must-have list.
No, one week after the Double Eleven, I have completely become a "porter" of express delivery. Just the sanitary napkins that Little Strawberry’s mother hoarded, I moved three boxes.
This sanitary napkin is really a consumable. I wonder if any girl has calculated privately how many sanitary napkins she will use in her life. In order to satisfy this damn curiosity, I decided to calculate an account.
1. The money that girls spend on sanitary napkins all their lives.
The age of menarche for girls is about 12-14 years old, and the average age of menopause for women in China is 49.5 years old.
We all take the average and calculate it according to the interval of about 36 years between the ages of 13 and 49.5.
Once a month, 12 times a year, that’s 432 times in 36 years! The time for girls to menstruate is generally 3-7 days, which is 5 days on average.
Theoretically, it is suggested that girls change a menstruation towel every 2-4 hours during the day.
Because menstrual blood is attached to menstruation towel for a long time, it will breed a large number of bacteria. If it is not replaced in time, the "cultivated" bacteria in menstruation towel will enter the body along the vagina, which may cause gynecological diseases such as vaginitis and cervicitis.
In this way, girls need to use at least four menstruation towels during the day and one at night when they sleep.
Moreover, in order not to dirty their underwear, many girls will pad it in advance a few days before they come. If they calculate it two days in advance, they will finally get an average of seven days of menstruation towels a month!
The price on the market now,The average price of daily sanitary napkins is 1 yuan/tablet,The average price of night sanitary napkins is 2 yuan/piece.So the cost of a day is 6 yuan,Menstruation is 42 yuan once.432 menstrual cycles *42 yuan/cycle = 18,144 yuan.Finally, it can be concluded that:The money that girls spend on sanitary napkins all their lives.Nearly 20 thousand yuan,It is equivalent to the price of buying 20 bottles of fairy water.This is only a rough estimate, and there may be some differences between girls with a large quantity and girls with a small quantity in the cost of menstruation towels.
2. How many tablets should I use each time?
When girls treat their period, they are always so ambivalent. When it comes, it bothers them. When it doesn’t come, they miss it, for fear that something will happen.
Generally speaking, a menstrual period lasts for 3~7 days, and the amount of blood loss per time is about 20~60 ml. If it exceeds 80 ml, it means menorrhagia, and if it is less than 20ml, it can be considered as menorrhagia.
However, some scholars believe that the menstrual flow of 5ml is not too small, provided that the doctor evaluates your ovarian function as normal.
How to judge this? It’s impossible to measure with a measuring cup, is it?
As a friend of women, although I can’t answer this question, I must solve it for everyone.
So, I humbly asked Zhou Xunhua, director of gynecology, and she gave us a good way to judge, that is, to observe your menstruation towel.
The amount of a daily menstruation towel that is completely soaked can be estimated as 20ml, and if only the middle part of menstruation towel is soaked, it accounts for about one third of the whole menstruation towel, it can be estimated as 5~7ml.
If each pack of sanitary napkins is 10 pieces, it is normal to use about four or five pieces every day on average. Except for the first day, one or two pieces will be soaked, and the menstruation towel replaced later will be soaked by about one third, and it is normal to use no more than two bags during each menstrual period.
(1) Excessive menstruation
It’s not enough to use 3 packs each time, and the replaced sanitary napkins are all wet, that is, the amount is too much.
There are many reasons for menorrhagia, such as dysfunctional uterine bleeding, hysteromyoma, adenomyosis and genital tract inflammation, and rare tumors.
(2) Too little menstruation
Every menstrual period lasts for 1 or 2 days, and it is enough to use one or two sanitary napkins every day, and it is only a little soaked, that is, the amount is too small.
The causes of menorrhagia are: endometrial damage (such as repeated abortion, endometritis, endometrial tuberculosis), or less hormones produced by ovaries.
After some quiet observation, if you find that your menstrual flow is abnormal, or too much or too little compared with before, you need to pay attention and go to the hospital in time.
3. Have you used all the menstruation towels correctly?
According to the above calculation, girls have to have 432 menstrual cycles in their lifetime, and they have to stay with their period for eight years. Therefore, sanitary napkins are very important for girls.
How to use sanitary napkins correctly and keep yourself away from the threat of gynecological diseases is something that every girl must master.
(1) Purchase regular and qualified sanitary napkins.
Look for these two criteria when purchasing sanitary napkins:
● Product standard GB/T 8939-2018-New regulations have been made on the indicators of formaldehyde and migratory fluorescent substances in sanitary napkins.
● Hygienic standard GB15979-2002——-specifies the amount of bacteria and fungi in sanitary napkins. According to this index, sanitary napkins can be divided into ordinary grade and disinfection grade.
When buying, try to choose products with complete information and recent production, and pay attention to whether the packaging is damaged or leaked.
The reason why the "bulk sanitary towel" that caused a heated discussion on the Internet some time ago is not recommended for everyone, because it is a three-no product, and the production materials and hygiene and safety cannot be guaranteed.
(2) Matters needing attention when using
Replace one diaper every 2-4 hours. If the amount is too large, the sanitary towel should be replaced if it is soaked within 2 hours.
Wash your hands before replacing! The process of unpacking, opening, smoothing and pasting sanitary napkins by hand can easily bring germs to sanitary napkins.
(3) Storage and preservation of sanitary napkins
Girls like to hoard goods, and sanitary napkins are no exception, but we must pay attention to the storage of sanitary napkins we bought.
● Sanitary napkins should be stored in a ventilated and dry environment, not in the bathroom or shower room for a long time, which is easy to breed bacteria and fungi.
● The shelf life of unopened sanitary napkins is generally 3 years. Once the package is opened, it is recommended to use it within 1 month.
● Do not use sanitary napkins that have passed the shelf life or are damp and moldy.
Mushrooms, I have given this knowledge about sanitary napkins. I hope every girl can correctly understand and use it and pay attention to her menstrual problems in time.
