Hitting the sack for eight hours a night is often touted as the ideal amount.
But only those living in one nation manage to get that much shut-eye each night, a study suggests.
Researchers in Korea and the UK monitored the sleeping habits of more than 30,000 people across 11 countries through smartwatches and surveys.

Researchers at the Korea Advanced Institute of Science and Technology and the UK-based Nokia Bell Labs wanted to determine whether where a person lived affected how much sleep they got.
The team examined smartwatch data from 30,082 people across 11 nations — including the UK, US and Spain — which was collected over a four-year period.
The volunteers also completed surveys on their sleep times. However, researchers found that these were inaccurate by up to one hour, when compared to data from the sleep trackers.
Results, published in the journal Scientific Reports, show that, overall, participants went to sleep around midnight and wake up at 7:42am, on average.

Those in Finland got the most — averaging eight hours and one minute and sleeping from 11:43pm to 7:43am.
