Using the app, called Sleep Cycle, researchers surveyed data from more than 140,000 people in the United States between Jan. 1 and 31 this year.

Users who live in snowy Northwestern states, including Montana, Wyoming, North Dakota and South Dakota, spent the longest time in bed — 7 hours and 20 minutes a night, on average.

That’s about 13 minutes longer than the average of people who live in the Southeastern states (Tennessee, Mississippi, Alabama, Georgia, South Carolina and Florida), who spent on average 7 hours and 7 minutes in bed.
