Some of the people who created many popular apps are telling kids to put their phones away — at least, a bit more often. The Center for Humane Technology is made up of people who used to work for big tech companies like Google, Facebook and Twitter. Now they want kids to stop using those apps and websites so much.

In early February, the center started a campaign called The Truth About Tech. Its goal is to teach students, parents and teachers about the dangers of spending too much time on smart phones and computers.

According to studies about kids and technology, more than 95 percent of elementary school-aged children spend at least part of every day using a computer or smart phone. About 78 percent of teens check their phones every hour, and more than half of them sleep with their phones in case they get a call or message during the night.

The Center for Humane Technology says that the apps and websites we use every day are purposely designed to keep us chatting, playing or watching online as much as possible. That includes social media like Snapchat, Instagram, Facebook and Twitter, websites like YouTube and online games. It also says that the tech companies talk only about the good aspects of their products and don’t mention the side effects.

Some physical problems, like headaches, eyestrain (眼疲劳), and neck pain are caused by using phones or computers too much. Students spending too much time online may find it hard to be focused on school work. Children and teenagers are more likely to have these problems because their brains, bodies and social skills are still developing.

One goal of The Truth About Tech campaign is to make sure that kids understand how technology affects them so they can make better decisions. The people behind the campaign also want governments and the tech companies themselves to take steps to protect children. When the leaders of the big technology companies are designing tech tools for kids, they should think about what they would want for their own children.
