P080 Using your Mobile/Tablet Device at Bedtime for Work: Implications for Adult Sleep and Job Performance

INTRODUCTION: A substantial number of workers post-COVID-19 now work at home. Remote work allows for greater flexibility in work timing including the preference to work at bedtime. Thus, increasing the likelihood of digital device use at bedtime with possible negative consequences for sleep, job recovery and, in turn, job performance. This interplay remains to be tested. METHODS: 202 university workers (54M, 144F; mean age (SD) = 48.38 ± 10.23y) completed a 10 day diary over two working weeks (Oct/Nov 2021) assessing digital device use, sleep, workload, worksite location, job recovery in the evening and job performance. RESULTS: Linear mixed model analyses revealed when comparing between individuals that greater digital device at bedtime was associated with greater wakefulness after sleep onset and shorter sleep and, in particular, if they worked from home compared to the office. By contrast, when comparing within individuals it was not the case if an individual used their digital device more on one night than another that this was associated with worse sleep nor was sleep worse on those nights when an individual had worked at home rather than the office. Analyses examining job recovery and job performance are currently under review. DISCUSSION: The present findings suggest that individuals who habitually use their digital device at bedtime are at a greater risk for poor sleep and supports the need for workplace implementations to discourage workers taking work to bed.
