teens who spend more time on screens are more likely to be depressed, and those who spend more time on nonscreen activities are less likely to be depressed (see Figure 3.8). Eighth graders who are heavy users of social media increase their risk of depression by 27%, while those who play sports, go to religious services, or even do homework cut their risk significantly. The teens who are the most active on social media are also those who are most in danger of developing depression, a mental health issue that devastates millions of US teens each year.
