The Relationship of Electronic Equipment Use Before Bedtime and Sleep Problems: Evidence from Young Adults of Southern China

Abstract

It was demonstrated that there are lots of impact of the usage of electronic equipment before bedtime to individual health. However previous studies focused on the acute short-term effects rather than long-term accumulating effect. To investigate this issue, 2330 participants were invited to answer the questionnaire about their usage of electronic equipment before bedtime and their sleep quality. Results indicated that: (1) Higher level of using electronic equipment before bedtime, longer sleep onset latency and shorter valid sleep time among individuals; (2) Higher level of using electronic equipment before bedtime, higher sleepiness level and lower self-satisfactions of academic, health, and sleep among individuals; (3) and as mediator, sleep efficiency plays an important role between usage of electronic equipment and daily sleepiness, as well between usage of electronic equipment and self-satisfactions. These results are useful to reveal the longterm accumulating effect of the usage of electronic equipment before bedtime and enrich the understanding of the effect to young adults’ sleep and daily performance.
