iGen: Why Today's Super-Connected Kids Are Growing Up Less Rebellious, More Tolerant, Less Happy--and Completely Unprepared for Adulthood--and What That Means for the Rest of Us

Many iGen’ers are so addicted to social media that they find it difficult to put down their phones and go to sleep when they should. “I stay up all night looking at my phone,” admits a 13-year-old from New Jersey in American Girls. She regularly hides under her covers at night, texting, so her mother doesn’t know she’s awake. She wakes up tired much of the time, but, she says, “I just drink a Red Bull.” Thirteen-year-old Athena told me the same thing: “Some of my friends don’t go to sleep until, like, two in the morning. “I assume just for summer?” I asked. “No, school, too,” she said. “And we have to get up at six forty-five.” Smartphone use may have decreased teens’ sleep time: more teens now sleep less than seven hours most nights (see Figure 4.12). Sleep experts say that teens should get about nine hours of sleep a night, so a teen who is getting less than seven hours a night is significantly sleep deprived. Fifty-seven percent more teens were sleep deprived in 2015 than in 1991. In just the three years between 2012 and 2015, 22% more teens failed to get seven hours of sleep.

This is or ought to be a shot across the bow for all parents and schools
