South Korea is one of the most sleep-deprived countries in the world, ranking 50th out of 57 surveyed markets in sleep habits and differences, according to IKEA Sleep Report 2025 released Wednesday.

The nation scored 59 points on IKEA’s global sleep index — below the worldwide average of 63.

Points for IKEA’s "sleep score," measured out of 100, were assigned based on five key factors: sleep quality, duration, consistency, time to fall asleep, and wake-up condition. The study surveyed 55,221 people worldwide, including 1,003 South Koreans.

China topped the ranking with 74 points, while Norway ranked lowest at 56 points.

When looking into the data in detail, South Koreans averaged just 6 hours and 27 minutes of sleep per night, the fourth-shortest among surveyed nations.

Japan logged the least sleep, averaging 6 hours and 10 minutes, while China was the only country where the average exceeded 7 hours.

South Koreans reported the lowest sleep satisfaction, with only 17 percent saying they sleep well. Parents echoed similar concerns, with only 38 percent believing their children under 18 get enough quality rest — far below the global average of 67 percent.
