Impact of pandemic lockdown on learning behaviour and sleep quality in German students: Results of an online survey before and during the pandemic.

Significant changes in sleeping patterns seem to be attributable to the pandemic lockdown as found in this self-reported student survey. While daytime sleepiness decreased and earlier overall bedtimes were noted, the impact on the irregularity of sleeping and learning patterns seems to be the most notable finding, as this affects overall quality of life and learning performance. Further studies are needed to validate these findings.
