Electronic Media Use and Sleep Quality: Updated Systematic Review and Meta-Analysis

Short summary

A meta-analysis of 55 studies (41,716 participants) found electronic media use significantly correlates with decreased sleep quality (pooled effect size 0.28) and increased sleep problems, with problematic use showing a stronger link (pooled effect size 0.33). General smartphone use had the highest effect (r=0.33) among general uses, while problematic internet use had the highest effect (r=0.51) among problematic uses. These effects were significantly stronger in Eastern cultures.
