Over 170 contestants took part in a Power Nap contest in South Korea's Seoul. Participants were free to wear sleepwear or any attire of their choice, with winners determined through a comprehensive evaluation of sleep duration and overall sleep quality. Now in its third consecutive year, the sleep competition underscores a chronic issue for South Koreans. Data shows South Korea is one of the most overworked and sleep-deprived nations among Organisation for Economic Co-operation and Development members. #southkorea #sleep #nap #seoul
