There are hundreds of factors that can predict how long and how well you can rest. Everyone talks about how television before bed, midnight snacks, caffeine, and chaotic work schedules can affect your sleep cycles. But what it’s as simple as what country you’re from?
Which country spends the most time in bed?
What country's children stay up the latest?
Is it true that Japanese workers often snooze on the job and during dinner parties or that Norwegian mothers leave their babies out on the snowy sidewalk to get an afternoon nap?
We’ve broken down the facts, spanning the continents to see what effect your global location has on the way you sleep.
With the explosion of Big Data, researchers are quickly becoming aware of just how much organic data they can harness from smartphone apps. Instead of relying on self-reports or clinical participation, the engineers of ENTRAIN discovered that they could track worldwide bedtime habits using an app, getting a much larger pool of data spread across a larger geographical location.
In their 2016 study in Science Advances, they reported on trends they saw worldwide. According to their data, people in the Netherlands are getting the most rest per night, while folks in Singapore and Japan are getting the least.
|Netherlands||8h : 5m|
|New Zealand||8h : 4m|
|France||8h : 3m|
|Australia||8h : 1m|
|Belgium||8h : 1m|
|Canada||7h : 58m|
|United Kingdom||7h : 54m|
|United States||7h : 52m|
|Japan||7h : 30m|
|Singapore||7h : 24m|
In general, they found that countries that were more geographically near each other and had similar cultures often shared very similar nighttime habits, regardless of global trends. These trends also often translate for children. For instance, according to a study in Sleep Medicine, children in Hong Kong go to bed, on average, 3 hours later than children in New Zealand.
Socioeconomic necessities, the prevalence of marriage, and cultural norms typically dictate who shares the bed worldwide.
With the advent of smartphones and cheaper and more accessible television, not to mention streaming services like Netflix, many people choose to unwind using technology before they go to bed. But is this having an adverse effect? A comprehensive study done in 2013 by the National Sleep Foundation showed that at least two-thirds of people in the U.S., U.K., Germany, Mexico, Japan, and Canada regularly use technology in some form right before bed, often lessening the amount of time they spend sleeping.
Is there a direct correlation between a lack of rest and technology? A World Health Organization (WHO) study of 8 rural areas of countries with lower resources and limited access to “24-hour culture,” smartphones, and televisions showed the same uptick in nighttime disruptions and sleep problems as countries with much higher access to technological advances.
One of the most interesting findings in the ENTRAIN study was that the amount people slept per night across the world had very little to do when they decided to wake up in the morning. Instead, resting times correlated more closely with when people decided to go to bed. Regardless of nationality, the later a person stayed up at night, the more likely they were to get fewer ZZZs.
Senior researcher on the study, Daniel Forger, told BBC, “Society is pushing us to stay up late, our [body] clocks are trying to get us up earlier and in the middle the amount of sleep is being sacrificed; that’s what we think is going on in the global sleep crisis.”
He concluded that people should worry less about alarm clocks and focus instead on their bedtime habits and the cultures that are encouraging them to stay up late at night instead of getting to bed at a reasonable hour.
20% of patients ask doctors for sleeping pills globally, and another study estimates that the amount of people suffering from sleep apnea has exploded to 1 billion, which is 10 times the amount previously thought.
