Which cities in the world get the most and the least sleep?

A new study reveals how much sleep residents of different cities in the world typically get, suggesting that people in Melbourne sleep the most and people in Tokyo sleep the least.

Jawbone, a fitness tracker company, looked at data from 5,000 users of UP tracker users worldwide. This number included tens of thousands of wearers from U.S. cities. Here is what the study found, according to the Wall Street Journal :

Cities with most hours of sleep:

Melbourne, Australia: 7:05

London, United Kingdom: 7:02

Denver, Colorado: 7:02

Brisbane, Australia: 7:00

Paris, France: 7:00

Cities with least hours of sleep:

Tokyo, Japan: 5:46

Seoul, South Korea: 5:55

Dubai, United Arab Emirates: 6:32

Singapore: 6:32

Mexico City, Mexico: 6:32

The new study also found that UP users in Brisbane, Australia, go to bed earliest - at 10:57 p.m., whereas users in Moscow, Russia, go to sleep latest at 12:46 a.m. People in Brisbane were also the earliest to rise at 6:29 a.m. and those in Moscow woke up latest at 8:08 a/m.

The data set used in the study also illustrated sleep patterns of UP users from seven cities on an average day. On a Monday this past March, a blog post noted : "New Yorkers work hard and play hard, and they're the first to bed and among the first to rise. Users in Tokyo are among some of the last to go to bed and the first to wake up, since they only average 5 hours and 46 min of night sleep," the blog post said.

On the same Monday, Dubai seemed to have the most leisurely sleep schedule, as 10 percent of the users in that city were still asleep by 11 a.m. The data also showed that people in Beijing and Madrid took afternoon naps.

"Only a maximum of 95 percent of a city is asleep at any given time, since the early risers are awake before the last to sleep are in bed," the blog post said.
