Is Evening Screen Reduction good for sleep quality?

The evidence is still emerging, so it's too early to say for certain. Multiple population-based and cohort studies, including a meta-analysis in young children and large cross-sectional studies in adults and youths, consistently find associations between evening screen use and poorer sleep quality or shorter sleep duration. That's reflected in an evidence score of 38/100 for its role in sleep quality, drawn from 5 studies, with an estimated impact on longevity rated moderate (38/100).
