On May 2, 2023, approximately 170 individuals participated in a 'power nap' contest along the Han River at Yeouido Hangang Park in Seoul, South Korea. This event, now in its third year, was organized by the Seoul Metropolitan Government to raise awareness about sleep deprivation, a growing concern in the country known for its demanding work culture. Participants, selected based on personal stories, competed not through physical prowess but by demonstrating their ability to fall into deep sleep in a public setting. They were judged on 'sleep concentration,' which assessed their ability to remain asleep despite distractions such as feather tickling and mosquito sounds. The competition utilized sleep-tracking data to evaluate performance, combining deep sleep duration with overall sleep quality. Many participants, including office workers and healthcare staff, cited fatigue from work and daily pressures as their motivation for entering the contest. One participant, Park Jun-seok, a university student, expressed the need for rest amid a hectic lifestyle, stating he often survives on just three to four hours of sleep per night.
