There are distinct differences in sleep patterns all over the world. Cultural values, traditions, biological needs, and environments all play a role in sleep habits and practices.
Number of Sleep Hours Needed by Region in the World
Our world has over 196 different countries, which means there's a big difference in bedtimes, wake times, and other sleep habits. There are factors that play a role in the duration, timing, and regularity of sleep.
Scientists have been able to collect data on the world's sleeping patterns through a smartphone app that helps determine the number of sleep hours in different countries. Some data from the ENTRAIN app showed:
People in Singapore and Japan slept for approximately 7 hours and 24 minutes each night.
People in the Netherlands slept for around 8 hours and 12 minutes each night.
Around 65 percent of the UK population gets only 6 hours and 27 minutes of sleep each night.
Americans get around 8 1/2 hours of sleep each night.
People in China get over 9 hours of sleep each night.
