3 . In the social media age, teenagers are sharing more information about themselves on social media sites than ever before.

According to a Common Sense Media research study, more than eight in ten teenagers have visited a social networking site like Facebook, and three out four teenagers now have an account on a social networking site.

However, while social media sites can improve teenagers’ communication abilities, experts say that social networking could be harmful to healthy teenage self-esteem. Health educator and motivational speaker Scott Fried began working with teenagers 22 years ago. He recently developed a new lecture, “Broken-Heartedness and Intimacy in the Age of Social Media,” to discuss with teenagers the differences between their personalities online and their true selves.

“The definition of growing up is bringing together many different parts of your personality,” Fried said. “As you grow, they turn into one whole personality. Now, you have a personality at school, at home, and online. The goal of being a teenager is to bring together all these different parts that are shown online in a complete way.”

Fried uses the phrase “compare and despair” to describe the bad effect of social media / on teenage self-esteem. you compare yourself to someone else, you’re usually going to end up despairing.”

Fried said, “One of the problems with social media is that we throw our best selves out there, or what we like to think of as our best self.”

Psychologist Nadine De Ciordany says that teenagers who already have low self-esteem can get easily depressed and give others their low self-esteem. She thinks social media is causing more and more depression. She adds that parents should educate their children early on social media.

“Teenagers can use a whole lot of resources that affect the way they deal with peer pressure,” De Giordaiiy said, “As the child is growing up, supervise(监督) what it is that they have access to. There is an age that social media is appropriate for and there is an age that isn’t appropriate for.”

5 . Social network Facebook has announced that it is pausing work on Instagram Kids, a young people’s version of Instagram, the photo and video-sharing app that Facebook owns. Instagram Kids would have been for 10 to 12-year-olds, who cannot officially use Instagram because it has an age limit of 13.

However, Facebook has recently been criticized for the effect that Instagram can have on teenagers’ mental health, and in particular how girls feel about their bodies.

Facebook has since published its own research which suggests that Instagram more often has a positive effect. However, the criticism has made the company decide that now is a bad time to develop the app for people who are younger than teenagers.

Adam Mosseri, the boss of the Instagram, said that this would give the company time to listen to and work with parents, experts, public officials and politicians and to show that Instagram Kids would take into account concerns around the mental health and wellbeing of its users.

Instagram Kids has not been completely cancelled, but if it is eventually launched in the future, you’ll need a parent or guardian’s permission to sign up. There will be no advertisements and you will only be able to access “age-appropriate” photos and videos.

Mosseri said that he understood people’s worries about the project and that these steps should help the company to get things right. However, several US politicians have called on Instagram not to restart work on the app. “A pause is not enough,” said a statement from four politicians who are keenly opposed to Instagram Kids. “Facebook has completely given up the benefit of the doubt when it comes to protecting young people online and it must completely abandon this project,” the statement said.
