Sleep is easy to come by in some locations and a luxury in others, depending on the degree of disturbance. Some locales are productive than others and it follows that some countries are more conducive to restful sleep than others. A review by the company Onebed has identified the most sleep-deprived countries worldwide, analysing factors such as average bedtime, wake-up time, sleep disorder prevalence, daily coffee consumption, and screen time.
From this, Colombia has emerged as the most sleep-deprived country with a combination of long working hours, high screen time, and an average sleep duration of 6 hours and 37 minutes per night. Saudi Arabia and Greece also rank high on the list of sleep-deprived nations, showing similar trends in sleep challenges, including shorter sleep durations and extended work schedules. In addition, Japan gets the least sleep among all the studied countries, with an average sleep duration of just 5 hours and 52 minutes per night.
The main outcomes of the review are: As can be seen from the table, Colombia ranks first with a composite score of 0.48. The country has significant sleep deprivation, driven by some of the longest working hours globally, totalling 2,297 hours per person annually.
Additionally, high screen time of 2,405 minutes further intensifies sleep challenges. Colombians also experience shorter sleep durations, averaging 6 hours and 37 minutes in bed. Saudi Arabia ranks second with a composite score of 0.
