"Honestly, I can't sleep at all." - Seol In Ah.

Actress Seol In Ah, known in the entertainment industry as a "healthy beauty," recently opened up about her struggle with insomnia.

On the September 7 episode of tvN's 'Steel Troops,' she revealed, "I've been taking sleeping pills for about five years, and it made me angry to think that I need medication just to fall asleep."

She went on to explain, "When I take sleeping pills, I can't focus on filming. I tried stopping, but after not sleeping properly for 3-4 days, my immune system collapsed, and I had to go to a university hospital where I was taking 24 pills a day just for my skin. I really want to get healthy this time."

Actor Jo Jin-woong also recently shared on the YouTube Channel Full Moon that his insomnia had worsened to the point that he would drink alone to cope. Other celebrities, including Choi Woo-sik, Lee Kyung-kyu, singer Park Seo-jin, and Brian, have also spoken about their struggles with insomnia.

The number of insomnia patients in South Korea continues to rise. According to the Health Insurance Review and Assessment Service, over 830,000 people sought treatment for insomnia last year, with the number of patients growing by an average of 7% annually over the past five years. Medically, insomnia is diagnosed when someone cannot sleep properly for more than two weeks, even when all conditions for sleep are met. If it takes more than 15-20 minutes to fall asleep, you frequently wake up during the night, or you wake up early in the morning and struggle to fall back asleep, you may be dealing with insomnia. Drinking alcohol to fall asleep is not a good idea. While it may feel like alcohol helps you fall asleep, it actually disrupts deep sleep and causes frequent waking. It’s also recommended to drink coffee only in the morning. Although it varies by individual, it usually takes adults 5-6 hours to break down caffeine. Drinking coffee in the evening can interfere with deep sleep, so it's better to avoid it or switch to decaf.
