First of all,the reason that I disagree with students using their social media is that it may hurt teenagers’ health.Since they watch their social media for a long time every day, the blue light may make their eyes hurt and they may have short-sightedness. Also,they may watch their social media too long,so their brain function may be worse,such as they cannot focus on other things,and their memories may be worse.

Moreover,social media may hurt the teenagers mental health. In social media, there are different types of people, some of them are good and some of them are bad. Some bad people not only cheat their money,but also hack their account secrets to do some web crimes.Some of the bad people may ask the teenagers to help him to buy something which also can steal the teenagers money.Therefore,the teenagers who was cheated by the hackers may be very sad and pessimistic.

Last but not least,social media may cause teenagers’ academics to drop.Since they watch social media all day, they do not have enough time to do their homework and revisions,therefore,their homework and their grades will be worse.For an example,Peter watch his Facebook for eight hours every day,his exam report become very bad,which is failed.

I think the government should make a policy,which can let social media companies follow.The policy is limiting teenagers from watching some things which are bad.Also,the companies can set a time limit for the teenagers,so that they can be protected by the company.
