Too much screen time?

Having the use of screens, computers, smartphones, and tablets, just to name a few, has given individuals the ability to be anywhere at any moment and allowed people to live in a global community. Video chatting, social networks, and the internet have changed the way we interact with each other and the way children learn. Technology is commonplace in educational settings and sometimes even necessary for learning and homework completion. Despite the need for children to be competent technology users in order to learn, there can be health risks and impeded learning as a result of screen overuse, specifically when screens are used for recreational purposes.

Excessive screen time has been associated with a variety of concerns for children, such as obesity, mood swings, and aggressive behavior, and has been found to negatively impact attention span and language and cognitive development (Carson & Janssen, 2012). Children ages 4 to 6 years old who spent more time on screen-based activities showed lower emotional understanding ability (Skalická, Wold Hygen, Stenseng, Kårstad, & Wichstrøm, 2019) and an increased risk of expressive speech delay (Livingstone & Franklin, 2018) because they lacked face-to-face interaction. One component of screen time is artificial light. Over exposure to light, especially artificial light from screens, can have a great effect on circadian rhythm, which is a normal, biological process that regulates one’s sleep-wake cycles. Moreover, artificial light, such as from self-luminous tablets, can cause significant melatonin suppression (i.e., melatonin is a hormone that signals the body that it is time for sleep) after only 2 hours of use (Hale & Guan, 2015).  Please find below additional negative effects that can result from too much recreational screen time (American Academy of Pediatrics, 2016; American Health Institute, 2019).

  • Irregular sleep schedules and shorter duration of sleep
  • Behavioral problems
  • Loss of social skills
  • Violence
  • Less time for play

So, what can parents can do to ensure age-appropriate screen time behaviors?

  1. Avoid screen exposure for children younger than 18 months.
  2. Watch high-quality television programming with your children so you can help interpret the content.
  3. Limit recreational screen time to no more than 2 hours per day.
  4. Create healthy relationships with screens as a family – be good digital role models.
