Too much screen time can lead to sleep problems in teens. But reducing screen time and blue light exposure can resolve these problems within a week.
Researchers from the Netherlands Institute of Neuroscience investigated the effects of screen time on adolescents and saw that teens who were exposed to screen time for more than four hours each day went to sleep later and suffered from low quality sleep.
The team hypothesized that blue light was the primary contributor to delayed sleep onset and sleep disruption. As a result, researchers had 25 students wear blue light-blocking glasses and reduce evening screen time.
They saw that these participants fell asleep earlier and saw improvements in sleep quality after just one week.
These findings show that the negative effects of screen time on sleep can be reversed by simply reducing evening screen use and blue light exposure.
