From: Increased sleep duration and delayed sleep timing during the COVID-19 pandemic
Self-reported sleep duration and timing in the United States during the years 2019 and 2020. Average time in bed (a) and midpoint of sleep (b) were calculated from self-reported bedtimes (c) and waketimes (d) for each month in 2019 (blue) and 2020 (red) in the United States. Bonferroni-adjusted p values for comparisons between each month of 2019 to the corresponding month of 2020 are indicated as follows: *p < 0.05, **p < 0.01, ***p < 0.001. Means ± SEM are shown.
