It’s no secret that teens spend a lot of time viewing screens. In fact, the average teen spends over seven hours a day on screens for entertainment alone. But science increasingly shows that too much screen time can negatively affect teens’ health. By sharing the article “Can Too Much Screen Time Harm You?” and the activity “Screen Time and Sleep Survey,” you can help students understand how screen time may impact their physical and emotional well-being.

LESSON:

READING COMPREHENSION QUESTIONS

  1. Explain why using your phone before bed might make it hard to sleep. (You may become more alert because you are engaged in your phone. The bright light from the screen can also cause you to feel less sleepy because it reduces the amount of melatonin your body produces. Melatonin is a natural chemical that helps you fall and stay asleep.)
  2. What evidence have scientists collected that suggests a link between screen time and your psychological health? (Some studies have shown a link between higher amounts of screen time and symptoms of depression; some kids who engage in excessive screen time have reported changes in their mood and behavior such as anxiety when they are away from their phone, neglecting responsibilities, and turning to screens to deal with stress.)
  3. Why do scientists think too much screen time can affect your brain development? (A study showed that the brains of some kids who engaged in more than seven hours a day of screen time had a thinner cortex [outer layer of the brain] than those of kids who participated in less screen time. The cortex is the part of the brain that processes information and is an area that undergoes significant development during adolescence.)
  4. What are some ways teens can help reduce the impact of screen time on their health? (Track screen time and set limits each day. Turn off screens 30 to 60 minutes before bed. Schedule time for non-screen-related activities. Keep track of emotions and mood related to screen time and ask for support if needed.)
