Apple’s employees, stock investors, and university researchers theorize that iPhones contribute in the rise of mental health issues in youth and ultimately negatively affect children.

Jana Partners LLC and the California State Teachers’ Retirement System, investors who claim to hold $2 million in the shares of Apple Inc., pled for Apple to take more precautionary measures to prevent the issues that Apple’s electronic devices present in an open letter to the company dated for January 8th.

The investors believe that Apple could be doing more to help parents regulate their child’s usage of their products. They imply that Apple’s current tactics to provide more control for parents is lackluster in the “all or nothing approach” presented in the parental controls in settings, and the array of apps that have more versatile options for parents makes choosing when difficult, leaving many parents to just give up.

According to Common Sense Media, the American teenager spends nearly 5 hours on it every day. Research from Jean M. Twenge, a professor and psychologist at San Diego State University, indicates “that U.S teenagers who spend 3 hours a day or more on electronic devices are 35% more likely, and those who spend 5 hours or more are 71% more likely, to have a risk factor for suicide than those who spend less than 1 hour.”

“It [children having iPhones] negatively affects their mental health because they’re so busy about what is going on and what everyone else is doing. You’re so busy trying to be everyone and they forget to try and be themselves,” said Maha Arafat, the mother of sophomore Sarah Arafat.

Out of 22 students surveyed, 86% of them report to own Apple products and 42% of that group report having mental health issues.

Their suggested solution is that Apple implements new tools and options for parents to help regulate their child’s phone usage, research and yearly reports to monitor the issue, and education to explain to parents why Apple wants to assist in making parental controls more accessible.

Similar allegations have not been reported for any other phone companies, although the investors stated that social media was a large factor in the declining of teenagers mental health and their attention span.

“I think every phone company can do something to help with this issue,” said junior Sarah Waldrop. “Social media, in general, stimulates my mental health issues, not necessarily the iPhone itself.”
