A new study out of Baylor University finds that 73% of atheists and agnostics sleep at least seven hours a night, compared to only 55% of Baptists and 63% of Catholics.
Atheists and agnostics also reported fewer difficulties falling asleep at night. The findings held even after controlling for details like age and socioeconomic status.
The American Academy of Sleep Medicine suggests at least seven hours of sleep per night.
The data comes from the Baylor Religious Survey, a nationwide poll that has been undertaken five times since 2005, and asks questions on religious beliefs, values, and behaviors. It includes topics like affiliations and personal beliefs about heaven. The latest rendition, in 2017, gathered responses from 11,000 surveys mailed out by Gallup.
