A new study reveals how much sleep residents of different cities in the world typically get. The study was conducted by Jawbone who are the maker of a wearable, digitized wristband (UP) that tracks its wearer’s movement and sleep. They analysed the data from 5000 worldwide users of the UP tracker to discover which cities get the most and least sleep.
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
Mexico City, Mexico: 6:32
The study of the data also provided insight into when these cities go to bed and when they rise in the morning. With the phrase “early to bed, early to rise” applying to people in Brisbane who go to bed earliest at 10.57pm and wake up earliest at 6.29am. Whereas people in Moscow, on the other hand, hit the sack latest at 12.46am and are also the latest to rise at 8.08am.
So how much sleep should we be getting?
Sleep needs vary across ages and are especially impacted by lifestyle and health. According to the National Institutes of Health, the average adult sleeps less than seven hours per night. In today’s fast-paced society, six or seven hours of sleep may sound pretty good. In reality, though, it’s a recipe for chronic sleep deprivation.
There is a big difference between the amount of sleep you can get by on and the amount you need to function optimally. Just because you're able to operate on seven hours of sleep doesn't mean you wouldn't feel a lot better and get more done if you spent an extra hour or two in bed.
Average sleep needs by age:
Newborn to 2 months old = 12 – 18 hours
3 months to 1 year old = 14 – 15 hours
1 to 3 years old = 12 – 14 hours
3-5 years old = 11 – 13 hours
5 to 12 years old = 10 – 11 hours
12 to 18 years old = 8.5 – 10 hours
Adults (18+) = 7.5 – 9 hours
