Healthcare workers' sleep quality after COVID‐19 infection: A cross‐sectional study

Abstract

Introduction The COVID‐19 pandemic not only affected physical health but also caused high levels of mental health problems including sleep disturbances, depression and post‐traumatic stress symptoms. The aim of this study was to examine the sleep parameters of healthcare workers before COVID‐19 infection and after recovery. Materials and Methods Healthcare workers who were infected with COVID‐19 and whose treatment was completed at least 30 days ago were included in the study. A web‐based cross‐sectional survey was conducted on the participants. Results The median PSQI score increased significantly after COVID‐19 infection (7.0) compared with the level before COVID‐19 infection (5.0). The increases in median scores for subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance, use of sleeping medication and daytime dysfunction were all significant. Conclusion Sleep quality decreased during the convalescence period from COVID‐19 infection as compared with the pre‐COVID‐19 period.

A comparison of pain, fatigue, and function between post–COVID-19 condition, fibromyalgia, and chronic fatigue syndrome: a survey study

“…Similarly, this cohort with post-COVID-19 showed limited impact on sleep disturbance, which has been reported in prior studies. 14,79 In addition to cardiopulmonary sequela, post-COVID-19 may impact a variety of neurosensory functions, such as loss of smell or taste. 39,66,123 The shared symptomology between post-COVID-19 and FMS may conversely suggest the potential for elevated sensory sensitivity.…”

Time to Sleep?—A Review of the Impact of the COVID-19 Pandemic on Sleep and Mental Health

“…Similar findings were also presented in two studies that evaluated self-reported sleep disturbances in HCW. Compared with before the initial infection, overall sleep quality and multiple sleep parameters such as latency, duration, efficiency, use of sleep medication and daytime dysfunction were found to be significantly altered in HCW at two months after the initial COVID-19 infection [ 131 ]. Similarly, Gaber et al [ 132 ] observed that almost half of HCW exhibited at least one symptom several months after the initial infection, with similar rates of sleep (49%) and mood (44%) disturbances.…”

“…The beforementioned studies described self-reported sleep disturbances, evaluated through questionnaires and interviews [ 120 , 121 , 122 , 123 , 124 , 125 , 126 , 127 , 131 , 132 ], and only one study reported PSQI values [ 131 ].…”

COVID-19 Vaccine Could Trigger the Relapse of Secondary Hypersomnia

“… 7 Sleep quality was found to be significantly decreased even after recovery of COVID-19 in those infected individuals. 24 It was also documented that preexisting EDS was significantly associated with the risk of mortality and hospitalization in patients infected by COVID-19. 25 Thus, there could be a close link between COVID-19 and EDS, albeit that the underlying mechanism remained unclear.…”
