It appears there is no sleep 'til Brooklyn— or even in Brooklyn. According to data from the fitness and health tracker Jawbone, residents in Brooklyn's Kings County go to sleep the latest, and residents of the Maui and Kauai counties in Hawaii are in bed the earliest.
Jawbone analyzed data from over a million consumer wristbands to track sleeping trends across America. Lead data scientist Dr. Brian Wilt from San Francisco created an interactive map that shows what time people fall asleep in cities and counties across the U.S.
New York City is known as the city that never sleeps, but according to the data, Brooklynites in Kings County go to sleep the latest at around 12:07 a.m. People in Manhattan typically go to bed at 11:55 p.m., Queens residents at 11:52 p.m., Bronx residents at 11:47 p.m., and Staten Island residents at 11:46 p.m.
The interactive map shows that the majority of counties on the East Coast go to sleep later than those on the West Coast. This is probably because western time zones include more sunlight because of the late setting sun.
"Unbeknownst to us, our body's circadian rhythms tune to sunlight hours, silently influencing you to go to bed when the sun goes down irrespective of the exact time," Jawbone says.
The Jawbone researchers found that the biggest difference in bedtimes occurred in counties that are close to time zone borderlines. Counties that did not have adequate data were blended with neighboring counties.
Based on the data, the researchers broke down how many hours of sleep people in the U.S. are getting each night based on their county. New York City averaged 6.82 hours of sleep each night. People in Pocahontas, W.Va. and Sawyer, Wis. got 7.5 hours of shuteye. Generally, the research shows that most people are not getting enough sleep each night.
According to the Mayo Clinic, adults should get at least seven to eight hours of sleep each night.
Jawbone plans to extend their research to track sleep patterns of people around the world.
