    We say that technology is a double-edged sword -while it brings convenience, it also brings new problems. The sword of “social media” even has a gender preference in its damage: It cuts deeper into girls than boys.

Earlier studies have shown that spending too much time on social media is bad for teenagers’ mental health. Constantly watching their friends show off “perfect” lives can hurt their own self-esteem (自尊). That’s not to mention the problems caused by online shaming and bullying (霸凌).

Jean Twenge, a professor at San Diego State University in the US, recently discovered an alarming trend: Since 2010, the number of teenage girls who suffer from major depression – showing signs like self-harm and suicide (自杀) - has increased much faster than that of boys. In an article she wrote at The Conversation, Twenge said social media, again, was to blame.

For starters, girls use social media more than boys. Boys tend to spend their screen time on games, where they talk to their teammates through headphones. This counts as real human contact. Girls, however, simply type and browse through posts, which is a much more isolated (孤立的) experience. “They’re not having a real-time conversation with someone,” Mary Fristad, psychologist at The Ohio State University, told NPR.

And when it comes to online shaming, girls are also more vulnerable than boys. “Girls face more pressure about their appearance, which could be exacerbated (加重) by social media,” wrote Twenge.

Shannon McLaughlin, for example, is an 18-year-old from Blackburn College in the US. She shared with the Guardian how social media made her feel depressed. “I was constantly confronted (面对) by women with skinny bodies who were praised for the way they looked. This was only made worse by the diet fixes and skinny culture,” she said. But McLaughlin found a solution. She started volunteering with the National Citizen Service, where she made face-to-face contact with people. “It’s so easy to forget the importance of real connections when we have hundreds of people that we’re trying to impress at our fingertips,” she told the Guardian. And she hopes that others “look up from their phones and focus more on the world around them”.
