The consequences of not getting enough sleep are evident to all of us—and yet we’re constantly staying up later than what our internal biological clocks are telling us. A new study shows the elusive nature of what’s to blame.
A new user data-driven study published in Scientific Advances is providing a fascinating glimpse into global sleep patterns, showing that the Dutch get about an hour more sleep each night than people in Singapore or Japan. The research also shows that women tend to get more sleep than men, and that the collective variability of our sleep patterns gets smaller as we age. What’s more, the study shows that social factors are preventing us from honoring our circadian rhythms, causing us to go to bed later than our internal biological clocks would like.
Back in 2014, a research team led by Daniel Forger of the University of Michigan released a free smartphone app called Entrain. His team has used the data collected by this app for the current study, which wasn’t strictly related to jet lag.
