New data released by Sleep Cycle, an alarm clock that tracks sleep patterns, show that teenagers in Europe have the best sleep quality -- and teenagers in the United States have the worst.
Sleep derivation can lead to a host of health problems in adults, such as obesity and increased risk of stroke and diabetes. But there are immediate consequences of sleep deprivation that affect teens, from the inconvenient to the outright fatal: Teens who haven't slept properly find it harder to learn during morning classes and have a higher risk of getting in a car accident on the way to school than their rested counterparts.
The Sleep Cycle data included information from more than 50,000 teenagers between the ages of 14 and 18. According to the National Sleep Foundation, teens need between 8 and 10 hours of sleep a night to function at their best, a benchmark few of them are hitting.
Between March and June of 2015, teenagers in the Netherlands logged the most sleep worldwide -- a little less than 8 hours per night on average -- while teenagers in Japan slept the least, a mere 6 hours per night.
