Pandemic 2021: In a 2.5-year horizontal study of more than 25,000,000 nights of sleep, people's sleep routines seem to be returning to “normal” after a year of significant change. Presumably, this could be due to re-opening and people re-engaging in their pre-pandemic lives. Specifically, in general, people slept longer during the pandemic until about February 2021, at which point sleep routines have been gradually returning to normal.
