Primary and secondary school students have little spare time. Some students spend their spare time reading some extracurricular books, doing some aerobics, chatting with their parents. Some students pick up their mobile phones as soon as they have time, and once they pick them up, it is difficult to put them down. The more you play, the more you want to play, the more you don't want to change channels, and the more you don't want to enter the learning state, thus entering a vicious circle and becoming a mobile phone fan.
The harm of playing mobile phone:
1, vision loss
Children use the tablet computer for more than two hours every day, and their eyesight can drop from 1.0 to about 0.5 in three months. According to the survey, children's vision dropped to 43.8 degrees myopia after playing iPhone for 20 minutes, and the average tear film rupture time was 5.3 seconds, with an average of 7.67 blinks per minute. Children's eyesight dropped to 4 1.7 degree myopia after playing ipad for 20 minutes.
2. Spinal problems
Children always like to lie sideways when playing mobile phones, no matter how comfortable they are. These seemingly comfortable postures are precisely the inducement of cervical spondylosis.
3. Affect children's attention
Modern people seem to have a disease that cannot be separated from mobile phones. They should look at their mobile phones every few minutes to avoid missing any important information. So are children. When they leave their mobile phones, what they want is not to study, but that time will pass quickly, so that they can play mobile phones again. In the long run, children's concentration will decline.
Because computer games are full of various sounds and light and shadow stimuli, it is very unfavorable for children's brain development. At the same time, playing computer games is easy to make children excited and unable to calm down and learn to think. Some children are even addicted, and it will be difficult to change.
4. Communication barriers
Playing mobile phone is no big deal, but it does affect our real communication. Think back, how much time did friends spend holding their mobile phones when they went out to parties?
Most children who are addicted to playing mobile phones and PADs don't like to communicate with the outside world, lack self-confidence in communication, and even don't know how to get along with children, which makes them more passive.
