Teen Smartphone Use At Night

In 2007 Apple introduced the iPhone. Smartphones, now ubiquitous, have engendered a number of cultural shifts— many of them positive. However, we have now come to realize that there are some downsides as well. 

The current generation of teenagers have grown up with this technology at their fingertips. We wanted to get a better sense of what kind of impact these mobile devices are having on our kids.

We looked at the bedtime texting and smartphone use of a cohort of 3000 middle and high school students in Edison, New Jersey, aged 12 to 17.  What we found was both startling and worrisome.

Adolescent texting and smartphone use at sleep time had harmful effects on many aspects of daytime functioning. 

And the bottom line is this: the use of this technology at night by students correlates with academic underperformance, shorter sleep duration, insomnia, daytime sleepiness, and “eveningness,” a condition where a person feels most alert at night—an obvious concern for students taking daytime classes.

Nearly 62% of our students used their smartphones in some capacity after bedtime, 56.7% texted/tweeted/messaged in bed, and 20.8% awoke to texts. Over 25% reported inadequate sleep, defined as less than 6 hours per night.

Our study confirms that smartphone use at bedtime is very common in American adolescents

The effects of this behavior appear to have significant consequences on our youth. Sleep helps to consolidate and reinforce memory, improve cognition, and aid in physiologic maturation. Interruption or shortening of sleep leads to cumulative deficits in these and other areas.

Parents and educators should be more cognizant of the impact sleep deprivation is having on our youth. And based on our research, it would be reasonable to impose limitations on the use of smartphones in adolescents. This is an area where parent and child themselves can have a direct impact on improving their sleep quality and quantity.
