Study: Set Smartphone Rules Before Age 15 to Boost Teens' Sleep and Grades
A recent study published in 'Discover Public Health' reveals that setting clear rules about smartphone use before teens turn 15 can significantly improve their sleep duration and academic performance.
The research, led by Virginie Sterpenich, found that teens who had their iPhone use restricted in the evenings and were not allowed to keep their iPhones in the bedroom overnight slept an average of 40 minutes longer than those without these restrictions. This simple rule change led to a notable increase in sleep duration, with no other restrictions, such as daily screen time limits or fixed bedtimes, showing a significant impact.
Moreover, the study found that these sleep-enhancing rules also translated to better school results for the teens. The researchers analysed responses from over 300 students aged 13 to 15, demonstrating that strict rules around evening iPhone use and bedroom access can have a substantial positive effect on both sleep and academic performance.
The study underscores the importance of establishing rules about iPhone use before teens reach 15. By restricting evening iPhone use and prohibiting iPhones in the bedroom overnight, parents can significantly improve their children's sleep duration and, in turn, their school performance.
