Is healthy sleep, both before and during the COVID-19 pandemic, prior to SARS-CoV-2 infection, protective against post–COVID-19 condition?

By Tarun Sai LomteJun 1 2023Reviewed by Lily Ramsey, LLM A recent study published in JAMA Network Open examined the relationship between multidimensional sleep health and post-coronavirus disease 2019 condition .

COVID-19 has compounded the severity of pre-existing sleep disorders. Unhealthy sleep dimensions, such as daytime sleepiness, late chronotype, long or short sleep duration, sleep apnea, and snoring, have been associated with susceptibility to and severity and mortality of COVID-19. The team measured sleep health dimensions before and during the pandemic . The five pre-pandemic sleep health dimensions were chronotype, snoring, insomnia, daytime dysfunction, and sleep duration.

Poisson regression was used to calculate relative risks and 95% confidence intervals for the individual associations of sleep dimensions and scores with PCC risk. Frontline healthcare workers were more likely to be younger and less likely to have comorbid conditions than others. There was a moderate correlation between sleep dimensions. PCC symptoms were reported by 44% of participants.The association of sleep score with PCC was not different by healthcare worker status. Chronotype, daytime dysfunction, insomnia, and sleep duration before the pandemic were associated with the risk of PCC when adjusted for age and ethnicity/race.
