Adolescents awakened at night by mobile phones reported more tiredness and rapid exhaustibility, but cognitive tests showed no link to memory or concentration.

Plain English Summary

Summary written for general audiences

In a cross-sectional study, 439 adolescents completed questionnaires about mobile phone use at night and health, and 233 provided operator-recorded use data. Standardized computerized cognitive tests assessed memory and concentration capacity. Adolescents who reported being awakened at least once a month had higher odds of daytime tiredness (OR 1.86) and rapid exhaustibility (OR 2.28). Similar associations were seen with objective operator-recorded data for tiredness (OR 1.63) and rapid exhaustibility (OR 2.32). Cognitive test performance was not related to nighttime mobile phone use.

Why This Matters

The researchers aimed to analyze how being awakened at night by mobile phones affects adolescents' perceived health and cognitive functions using both self-reported and objective operator-recorded data. Overall, being awakened at night was associated with increased reports of tiredness, rapid exhaustibility, headache, and physical ill-being, but not with memory and concentration capacity. The authors suggest prevention strategies should help adolescents set limits on their accessibility by mobile phone, especially at night. Data were analyzed with multivariable regression models adjusted for confounders including amount of mobile phone use.

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.
