NMIXX’s Sullyoon Sleep Comment: What Reliable Sources Actually Confirm
What Happened?
A claim circulating online suggests that NMIXX member Sullyoon said sleep is a “waste of time” and faced backlash as a result. After checking available sources, KpopBio found no verified evidence that Sullyoon made this statement or that it triggered a significant controversy.
What does exist is a longer pattern of Sullyoon discussing her unusual sleep habits in interviews and variety content. A forum thread titled “Sullyoon does not have the best opinion of sleep” was started on K-Pop Source on September 28, 2026, but the thread contains only a handful of replies and does not quote any specific statement from Sullyoon calling sleep a waste of time.
The topic appears to be a mischaracterization of Sullyoon’s known sleep-related comments rather than a confirmed news event. This article explains what is actually documented.

What Is Confirmed About Sullyoon’s Sleep Comments
Sullyoon has spoken publicly about her sleep habits on multiple occasions, and those comments are documented in Korean media.
On May 16, 2026, Sullyoon and fellow NMIXX member Bae appeared on the YouTube channel “Ggondaehee” for an episode titled “Bae, Sullyoon, and NMIXX Vol. 3.” During the conversation, host Kim Dae-hee asked Sullyoon about her reputation for sleeping well regardless of time or place. Sullyoon admitted, “I tend to sleep pretty well,” and when asked how well, she joked that she could fall asleep even during the filming itself.
Bae then shared a story about seeing Sullyoon asleep in a chair on set. “She looked like a statue,” Bae said. “Everyone else was busy coming and going, and only Sullyoon was like that. I even took photos and said, ‘There’s a statue over there!’ But she absolutely would not wake up.”
Sullyoon also revealed a surprising detail: despite falling asleep easily in public, she struggles to sleep well in her own bed. “But I can’t sleep well in bed,” she said. “I keep waking up in the middle of the night.”
These comments were reported by TV Report through Naver and later picked up by international K-pop outlets, including Pannatic and WowKeren.
What Is Being Reported vs. What Is Unconfirmed
Confirmed: Sullyoon has spoken about falling asleep easily and even sleeping while sitting upright. These comments are documented in a May 2026 YouTube appearance and were reported by Korean media.
Unconfirmed: The specific claim that Sullyoon said sleep is a “waste of time” does not appear in any reliable source. It is not present in the Nate/TV Report article, the Pannatic translation, or any other verified coverage of her sleep-related comments. The K-Pop Source forum thread that uses a similar framing does not include a direct quote from Sullyoon making this statement.
No evidence of backlash: There is no credible reporting that Sullyoon faced significant criticism or backlash over her sleep comments. The May 2026 variety appearance was received as lighthearted content, with fans finding her sleep habits amusing rather than controversial.
Why This Topic Is Getting Attention
Sullyoon has been a frequent subject of online discussion throughout 2026, though not all of it has been positive. In June 2026, she drew widespread attention after a video showed her performing through severe back pain during NMIXX’s Bangkok concert. She later explained on the fan platform Bubble that both her company and her hospital advised her to rest, but she chose to perform because she wanted to be on stage.
That incident generated genuine debate, with some fans criticizing her decision to perform while injured and others defending her dedication. JYP Entertainment later confirmed that Sullyoon would perform seated at the Singapore stop of NMIXX’s “EPISODE 1: ZERO FRONTIER” world tour.
More recently, in early September 2026, Sullyoon apologized after an incident at a signing event where she was seen crying following a protest from a fan. According to Kstyle, the situation involved a “homma” (fan photographer) controversy, and Sullyoon addressed the matter on Bubble, saying, “I know that NSWER coming to cheer for us is not something to take for granted. I should have taken better care of NSWER, but I wasn’t able to. I’m very sorry.”
These are real, documented events. The “sleep is a waste of time” claim does not fit into any of them.

Fan Reactions and Online Discussion
The response to Sullyoon’s documented sleep comments in May 2026 was largely lighthearted. Fans found her ability to sleep anywhere relatable and amusing. Comments on the Pannatic translation and WowKeren coverage reflected amusement rather than criticism.
The K-Pop Source forum thread from September 28, 2026, includes only four replies and 22 views at the time of writing.
