This longitudinal study aims to investigate the impact of COVID-19 infection on self-reported and objective sleep of good sleepers.Methods: Fifteen good sleepers, with prior COVID infection, completed self-reported and objective sleep assessments at 3 time points: pre-COVID-19 infection, short-term post-COVID-19 infection for 1 month and long-term post-COVID-19 infection for 6 months. Self-reported sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI). Self-reported sleep onset latency (s-SOL) and sleep efficiency (s-SE) were extracted from the PSQI. Objective sleep was assessed by overnight polysomnography. Nighttime electroencephalogram (EEG) relative power at central EEG derivations during sleep was calculated.Results: Total scores of the PSQI (P=0.003), s-SOL (P=0.017) and s-SE (P=0.040) changed across the 3 time points. Specifically, total PSQI scores (P=0.002) and s-SOL (P=0.011) increased, while s-SE decreased (P=0.019) from the pre-COVID-19 infected period to the short-term post-COVID-19 infected period. However, there were no significant differences regarding PSQI scores, s-SOL or s-SE between short-term and long-term post-COVID-19 infected periods, or between pre-COVID-19 and long-term post-COVID-19 infected periods (all P> 0.999). The changes in objective sleep were not significant across different periods except shorter o-SOL at the long-term post-COVID-19 infected period compared to the pre-COVID-19 (P=0.028) and short-term post-COVID-19 infected periods (P=0.010). Similarly, the changes in EEG relative power were not significant across different periods except the relative alpha EEG power during REM sleep (P=0.007).Conclusion: COVID-19 infection has temporary adverse effect on self-reported sleep but no effect on objective sleep of good sleepers.Keywords: COVID-19 infection, self-reported sleep, objective sleep |
