In fact, whether it is homework or electronic products, it may affect the sleep of primary and secondary school students.
First of all, talk about electronic products. With the arrival of the new era, high-tech products have also entered our sight. People have also entered the mobile phone era from the previous black-and-white TV era. Now a mobile phone can know everything in the world. Basically, no matter on the street or at family gatherings, everyone will have their own mobile phone, and primary and secondary school students are no exception. Nowadays, many primary and middle school students are left-behind children, and their parents are not around all the year round, so in order to let their children contact their parents, parents will buy mobile phones for their children. But for children, mobile phones are not used to contact their parents, but to play games and socialize. Some children can even play games all night and then sleep at their desks during class. This also leads to the reason why so many primary and middle school students sleep less than eight hours now.
Secondly, there is too much homework. Not all students' poor sleep quality is due to electronic products, but some children who love learning are really because of learning. This happened to a friend I know. His child is only five years old, so he signed up for nine interest classes, only seven days a week, which means that the child not only has to finish his homework, but also has to attend two interest classes for one or two days, completely depriving the child of the right to play and failing to combine work and rest. Children's brain capacity is not as large as that of adults, and their acceptance ability is not particularly good. If children are forced to master so much knowledge at once, they may not be able to stand it. Children should sleep more during their development, but this parent completely deprives their children of the time to sleep and play, which will lead to their inability to combine work and rest. In addition to studying every day, it is naturally impossible to sleep more than eight hours.
In fact, the reason that affects children's sleep quality is nothing more than family factors. Parents buy mobile phones for their children when they can't accompany them all the year round, and children will get carried away and play mobile phones all night without supervision.
Therefore, for primary and secondary schools, the quality of sleep does not exceed eight hours, not all because of homework, but more because of scientific and technological products. (The picture comes from the Internet. If there is any infringement, please contact to delete it. )
