iPhone Separation Anxiety
The University of Missouri released a study this year in which they had participants solve two puzzles, one with their iPhones in their possession and one with their iPhones unanswerable (and ringing). They found that subject's reported levels of anxiety, heart rate, and blood pressures rose when the phone was away. The participants in this state also did a worse job solving the puzzle. This is not addiction-level phone attachment, but it does help illustrate how phone use often activates the reward system in many people's brains. "The device has a tendency to take control over your life, if you allow it," says Greenfield. The best way to fix this problem is exactly what you think, turn off the push notifications. Cash even suggests prescribing certain times to check your phone or email.
