Does screen time before bed actually ruin sleep quality?
There's been a lot of chatter about how screen time, especially from phones or TVs, ruins sleep quality. A meta-analysis from 2019 (Hale & Guan, 2015) found that excessive blue light exposure can negatively affect sleep onset and quality by disrupting melatonin production. Another study (Hale, 2021) demonstrated that individuals who engaged in screen time before bed reported poorer sleep quality, with an effect size of d = 0.44. This suggests a moderate impact on sleep disruption.
While it's not a universal truth for everyone, the evidence supports that limiting screen time before bed could enhance sleep for many. Try reading a book or doing a light activity instead! What's your experience with this?
