A short essay on the harm of playing mobile phones to students

The main hazards of playing mobile phones to students are:

First, it harms physical and mental health. Frequent and long-term use of mobile phones is harmful to human health. The main manifestations are memory loss, sleep disorder, irritability and headache. Middle school students are in the period of growth and development, and their physical functions are still not perfect. Mobile phone radiation harms their physical development, leading to obvious decline in understanding, reaction and memory, and disorder of immune function.

Second, cheating in exams corrupts the style of study. In the academic performance examination, some students cheat their parents, teachers and themselves through their mobile phones, which seriously endangers the teaching order, corrupts the style of examination and study, makes students not enterprising, does not concentrate on their studies, and their grades drop, leaving them hopeless for further study.

The third is to undermine school discipline and affect teaching. Students hiding under the covers use their mobile phones to send and receive text messages, read novels and play games, which not only affects their own rest, but also interferes with others' rest, seriously affecting the learning efficiency the next day. When the mobile phone rings in class, it will even disturb the teaching order, affect the efficiency of class and despise the teacher's labor. Not only the teacher is disgusted, but also other students are extremely disgusted.

Fourth, compare with others and be extravagant and wasteful. When students buy mobile phones, many people are jealous and want to have a mobile phone to show off in front of their classmates. The upgrading of mobile phones is getting faster and faster, and the functions of mobile phones are becoming more and more comprehensive. The comparison of mobile phone functions is becoming more and more serious. Some students spend as little as tens of yuan on mobile phones every month, and as much as two or three hundred yuan. Extravagance and waste put a great burden on the family.

The sixth is to invade the privacy of others. Students like to sneak shots with "camera" mobile phones as jokes; Even deliberately photographed the scene of the spoof and sent it online to promote uncivilized behavior, unconsciously infringing on the privacy rights of others.

Seventh, it is easy to fall into the trap of mobile phones. Nowadays, short messages that cheat people by winning prizes and lie about family accidents abound, adult jokes and bad short messages are hard to prevent, and divination, treachery and boring short messages are overwhelming. Students are immature, have no social experience and are easily deceived.
