BACKGROUND: Sleep hygiene habits and self-reported sleep quality of those who work from home have yet to be fully understood. As working from home was widely implemented during the COVID-19 pandemic, the period might be a convenient model for studying the measures, as mentioned earlier. OBJECTIVE: This study aimed to assess sleep hygiene habits and self-reported sleep quality in people working from home in March 2020, when the COVID-19 pandemic began. METHOD: This study was designed as a cross-sectional web-based survey. An anonymous questionnaire consisted of sociodemographic variables and questions about personal habits, e.g., exercise activities and caffeine consumption. The outcome measures to assess sleep hygiene and sleep quality were the Sleep Hygiene Index (SHI) before and after the home office (HO) and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: A total of 204 responses were received. The prevalence of significant sleep disturbance (PSQI > 5) was 51 %. The mean PSQI and SHI scores were 6.15±3.385 and 17.67±7.836, respectively. PSQI and SHI showed a significant mutual positive correlation at the level of significance p < 0.001. The total score for SHI was similar before and after working from home (p = 0.982). However, differences were observed in its components. CONCLUSION: The total score on SHI did not change when compared before and during HO. However, working from home was associated with sleep hygiene malpractice in some individual components of SHI. On the other hand, some aspects of sleep hygiene behavior improved during HO.
