Yes, studies indicate that Koreans experience significantly shorter sleep durations compared to many other countries, which strongly suggests that staying up late is a common practice.
Data Reveals Shorter Sleep in Korea
Research has specifically investigated the sleep habits of populations worldwide to understand global trends and differences. A notable study conducted by researchers from the National University of Singapore and Finnish health technology company Oura Health Oy analyzed sleep patterns across 35 countries.
Key findings from this study regarding Korea highlight a distinct pattern:
- Average Sleep Duration: Koreans sleep an average of 6.3 hours per day.
- Global Ranking: This places Korea as the country with the second shortest average sleep duration among the 35 nations included in the study.
Connecting Short Sleep to Late Nights
An average sleep time of just 6.3 hours is considerably less than the 7 to 9 hours recommended for most adults to maintain good health and cognitive function. While reduced sleep could theoretically result solely from extremely early wake-up times, achieving such a short duration consistently often involves going to bed late. For individuals with standard work or school schedules requiring early mornings, consistently getting only 6.3 hours typically means frequently staying up past midnight.
Therefore, the data on significantly shorter average sleep duration strongly implies that staying up late is a prevalent habit for many people in Korea, contributing to this pattern of limited sleep.
Conclusion
Based on compelling study data showing that Koreans have one of the shortest average sleep durations globally at 6.3 hours per day, it is highly probable that staying up late is a widespread behavior that contributes significantly to this pattern of limited sleep compared to populations in many other countries.
