Do you surf on your tablet or text on your phone while watching TV? If so, how’s your mood? A new study asserts that the more you multitask using multiple screens, the more likely you are to feel depressed or anxious. The question is: why?

Cognitive psychologist Mark Becker at Michigan State University said that the question remains whether “second screening” is the cause of the psychological stress, or whether people who are anxious and depressed tend to use multiple screens at once.

If you second screen frequently and feel anxious or depressed, Becker recommends trying a media vacation. “Turn off the systems for a while and see if you feel better or worse,” he said.
