A medical expert claimed that work hours longer than 13 hours a day increases the risk of cerebral hemorrhage by up to 94 percent.

Compared to those whose daily work hours are four hours or less, those working for 13 hours or longer are 94 percent more likely to experience brain damage.

The study was conducted by Prof. Kim Beom-jun from Bundang Seoul National University Hospital. Kim compared 940 cerebral hemorrhage patients and 1,800 healthy people in terms of occupation, work hours, level of severance in work, and frequency of change of work shift.

The average work hours of Koreans are from nine to 12 hours a day, which Kim pointed out can raise the same risk by 38 percent.
