Poor work-life balance is blamed in part for increasing numbers of women in South Korea seeking help for sleep disorders, reports The Korea Herald.

According to data, the number of female sleep disorder patients rose from 24,536 in 2012 to 28,930 in 2014, with the highest average annual increase rate among all gender and age groups at 10.4 percent. The number of all Korean sleep disorder patients increased from 358,000 to 414,000 in the same period, with an average yearly increase rate of 7.6 percent. As of last year, 59.5 percent of all sleep disorder patients were women.
