I think what you're describing are the behavioral aspects resulting from covid. I've done some analysis on the changes in sleep behaviors on about 100,000 people using a sleep tracking app, if you're interested: https://jeffhuang.com/covid_sleep/
And all in all, about half of people have changed their sleep behavior; about 2/3 of those sleep more hours, and 1/3 of them sleep fewer hours. The usual caveat of a self-selecting population sample applies here.
