I believe that most of the rural girls born in the 70.80s have seen lice, right? The most commonly used tool is the grate, and every time the lice brushed down are quickly strangled with their fingernails, it is estimated that every moment is the most decompressing moment.
And why have they all mysteriously disappeared now? In the past few decades, the rural areas of the mainland have undergone tremendous changes. These changes are not only reflected in economic development, infrastructure construction, and the improvement of people's living standards, but also in some subtle living habits. Among them, the disappearance of lice is a phenomenon worth exploring.
First, we need to understand the parasitism and spread of lice. Lice are small insects that live on human hair and feed on the blood of their hosts. Lice are very reproductive, and once they are parasitic on the human body, they multiply rapidly, causing the number of lice to increase dramatically. In the past, living conditions in rural areas were relatively poor and sanitation was poor, which provided favorable conditions for the spread of lice. Nowadays, with the improvement of rural living conditions and the improvement of sanitary environment, the living space of lice has been greatly compressed.
Secondly, the improvement of rural living conditions is closely related to the reduction of lice. In the past, living conditions in rural areas were limited, and many families had only one room, and it was difficult to wash and dry bedding and clothes regularly. Nowadays, with the improvement of family economic conditions, the daily necessities of rural residents are more abundant, bedding and clothing are replaced and washed in time, and the sanitary conditions have been greatly improved. Lice have lost the soil on which they can survive, and naturally they have decreased.
In addition, the improvement of hygiene habits is also an important reason for the disappearance of lice. In the past, rural residents did not have a good understanding of hygiene habits, did not wash their bodies and hair frequently, and did not dry their clothes enough, which provided lice with a chance to survive. Now, with the popularization of hygiene knowledge, rural residents have gradually developed good hygiene habits, regularly bathing, washing their hair, and changing clothes, so that lice have nowhere to parasitize.
In addition, the popularization of modern medical knowledge has also had a positive impact on the prevention and control of lice. In the past, rural residents had limited access to lice control and often resorted to extreme measures such as the application of pesticides. Nowadays, with the popularization of medical knowledge, people have learned more safe and effective lice prevention and control methods, such as using shampoo, conditioner, etc., which can not only effectively prevent lice, but also protect human health.
In the process of urbanization, the movement of people from rural areas has also had an impact on the spread of lice. In the past, rural populations were less mobile, and lice could survive and spread in one place for a long time. Now, with the advancement of urbanization, the rural population movement has intensified, and the transmission routes of lice have been limited, and the natural reduction has decreased.
To sum up, behind the disappearance of lice is a great change in the living environment of rural areas in the mainland. This change is not only reflected in the economy, infrastructure, etc., but also in people's hygiene habits, life knowledge, etc. In the future, with the continuous improvement of rural development in the mainland, we have reason to believe that the life of rural residents will be better, and pests such as lice will gradually stay away from our lives. However, we should also be wary that as the living environment improves, some new health problems may gradually emerge. Therefore, we must continue to strengthen public health education in rural areas, improve the health quality of rural residents, and lay a solid foundation for realizing a moderately prosperous society in all respects.
