Seven in ten Korean adults suffer from sleepless nights due to poor sleep quality, according to a new survey.
Sleep specialist brand Simmons held a symposium with the Korean Society of Sleep Medicine at Seoul St. Mary's Hospital on the 11th and announced the survey results.
The online survey was conducted from January 27 to 30 among 1,000 people aged 19 to 69 nationwide.
Sleep specialist brand Simmons is joining forces with the Korean Society of Sleep Medicine, the nation's leading academic organization for sleep medicine, to promote healthier sleep environments for the public.
In the survey, 72.1% of respondents said they experience discomfort from poor sleep quality at least once a week. Specific complaints (multiple responses allowed) included reduced concentration during work or study at 52.4%, while 46.5% reported physical discomfort such as headaches and skin problems. Other responses included emotional changes such as mood swings and irritability at 41.5%, memory decline at 33.1%, and drowsiness at 1.7%.
"Psychological anxiety and stress" was cited as the leading cause of deteriorating sleep quality by 65.8% of respondents.
Among those surveyed, 69.2% slept less than seven hours, the minimum recommended sleep duration for adults.
The most common bedtime was "between 11 p.m. and 1 a.m.," cited by 58.5% of respondents.
Based on these findings, Simmons and the Society plan to host sleep classes and promote proper sleep culture.
Simmons signed a memorandum of understanding with the Korean Society of Sleep Medicine on the same day.
The agreement aims to raise public awareness about sleep health and establish a systematic cooperation framework. The signing ceremony was attended by key representatives from both sides, including Simmons CEO Kim Min-su and Korean Society of Sleep Medicine President Park Chan-soon.
Under the agreement, both parties will engage in various collaborative activities, including conducting and publishing the Korea Sleep Health Report, releasing and accumulating data for the Korea Sleep Integrity Quotient (KSIQ), and hosting sleep classes.
"The partnership with the Korean Society of Sleep Medicine, which has laid the foundation for sleep medicine in Korea, will solidify the value of healthy sleep that Simmons pursues on a medical basis," said Simmons CEO Kim Min-su. "Simmons will continue to contribute to spreading proper sleep culture as a sleep specialist brand."
