Singer Lee Sang-soon opens up about lingering effects of vagus nerve disorder: 'Standing is hard'

Singer Lee Sang-soon has opened up about the lingering aftereffects of a vagus nerve disorder.

Thursday's episode of MBC FM4U's "Wanbyeokhan Haru Isangsoon-imnida," a radio program hosted by Lee, featured members of the duo Peppertones — Shin Jae-pyeong and Lee Jang-won — as guests.

During the broadcast, the Peppertones members mentioned that most of their concerts are held in a standing format.

Shin said the most thrilling moment is singing along with the audience, adding that seated arrangements are available only at year-end performances.

Lee, listening to the exchange, drew attention when he said he had been avoiding standing concerts. "I have a health issue that makes standing difficult," Lee added.

Lee briefly stepped away from hosting the radio program in August after doctors recommended rest following a diagnosis of vagus nerve dysfunction, a neurological condition.

At the time, Lee said prolonged fatigue had led to tests that revealed neurological symptoms related to reduced vagus nerve function, and that he was focusing on recovery under medical advice.

After about a month of rest, Lee returned to the radio show and has been gradually resuming his normal routine.

Lee married singer Lee Hyo-ri in 2013. The couple, who had been living on Jeju Island, relocated to Seoul in 2024.
