Teens awakened by phones monthly show 86% higher odds of daytime tiredness, even when total usage is controlled.

Plain English Summary

Summary written for general audiences

Researchers studied 439 Swiss adolescents to see how nighttime mobile phone interruptions affect their health and thinking abilities. They found that teens awakened by phones at least once monthly were 86% more likely to experience daytime tiredness and over twice as likely to feel rapidly exhausted. However, the interruptions didn't impair memory or concentration on cognitive tests, suggesting the main impact is on energy levels rather than mental performance.

Study Details

Many adolescents tend to leave their mobile phones turned on during night, accepting that they may be awakened by an incoming text message or call. Using self-reported and objective operator recorded mobile phone use data, we thus aimed to analyze how being awakened during night by mobile phone affects adolescents' perceived health and cognitive functions.

Quick Questions About This Study

Yes, Swiss research found adolescents awakened by mobile phones at least once monthly were 86% more likely to experience daytime tiredness. The 2015 study of 439 teens showed nighttime phone interruptions significantly increased fatigue and rapid exhaustibility the following day.
No, nighttime mobile phone interruptions don't impair memory or concentration abilities in teenagers. The Swiss study found that while phone calls disrupting sleep increased tiredness, cognitive tests showed no decline in mental performance or focus capacity among adolescents.
Teens awakened by phones monthly are over twice as likely to feel rapidly exhausted. The Swiss research found an odds ratio of 2.28, meaning adolescents interrupted by nighttime phone calls had more than double the risk of experiencing quick exhaustibility.
Nighttime phone interruptions increase tiredness, rapid exhaustibility, headaches, and physical ill-being in teenagers. The 2015 Swiss study of 439 adolescents found these health symptoms rose significantly when mobile phones disrupted sleep, though mental performance remained unaffected.
Yes, researchers recommend helping adolescents set limits for mobile phone accessibility during night hours. The Swiss study concluded that prevention strategies should focus on reducing nighttime phone interruptions to prevent increased tiredness and health symptoms in teenagers.
