A new study shows those with a later work schedule get more sleep, which has prompted experts to suggest a later workday, according to Vox.

Roughly 40 percent of Americans are sleeping less than they should. And a new study, published in the journal SLEEP, found that the main thing people were doing instead of sleeping was working. “It was evident across all sociodemographic strata no matter how we approached the question,” study co-author Mathias Basner, a sleep psychiatrist at the University of Pennsylvania, said in an email.
