Today’s my topic is that teenagers under the age of 18 are not allowed to use smartphone for more than 30minutes a day. The reasons
are as follows.
First, addiction
Recently, we saw teenagers using the smartphone in
the subway and bus, also even using it during the lunch. Students who carry their
smartphones in the class room spend most of their time texting and browsing in
the internet instead of pay attention to their teacher.
Adolescents should do reading books, going out
with friends, exercising. But they don’t have the time to read books, to meke
friends, to exercise or even do homeworks. Because of spending time with using smartphones.
Teenagers
are very diffcult to judge their own work and control themselves. So, they can
easily become addicted by overuse of their smartphones.
Second, brain development
Teenagers are to be exposed
violent video games, violent movies. So adolescents spend large amounts of time
playing them with their smartphones. / These teenagers are easy to accept external stimulus passively./ Actually teenagers
to live their life well, they must develop their strengths in the future. They have to design and pioneer their own life. If they are exposed recurring to such stimulus, their judgment and creativity would be lost or lacking. Therefore, teenagers under the age of 18 should refrain from using smartphones.
Third, health
Teenagers’s excessive use of smartphones can have bad effects on their
body health and mental heath
too. One of the most
negative effects of using smartphone is near-sightness. The condition is caused
by spending long hours staring at the screen of a smartphone at a
short-distance. Another health problems are as turtle neck syndrome, depression, Obsessions, anxiety, interpersonal
affliction, impulse control disorder and sleep disorder. Especially Obsessions and depression are the most serious.
Therefore, to relieve these problems, young people should reduce their smartphone usage to less
than 30 minutes a day.
