  • Pushkin.

  • If you follow the research on the science of happiness,

  • you 've probably heard a lot about the connection between screen time and well-being.

  • It's a problem that I think about a lot and a topic that we talk about on the show a lot.

  • But lately, I found myself wondering, what if we're missing the bigger picture?

  • We hear, you know, the mental health epidemic,

  • growing rates of depression and anxiety has to do with the content that we get, right?

  • This is journalist Manoush Zamorodi.

  • Some of you may also know Manoush as the host of NPR's TED Radio Hour.

  • This idea that we are taking in outrage, headlines, violence, also.

  • Comparing ourselves to other people, that it is purely sort of a psychological thing,

  • that it 's something going on in our heads.

  • Manoush says that given all the focus on how technology affects our minds,

  • it 's easy to overlook another important part of the story.

  • What we 're not taking into account is what we actually do with our bodies

  • when we are spending all that time taking in that content.

  • We are sitting and looking at a screen for long stretches of time.

  • And we now know that the average American adult spends 12 and a half hours consuming media a day.

  • And I mean, that's a lot of hours.

  • That's a lot of hours.
