"The only management method you must follow"… Kim Hee-ae, doing 'this' before 10 PM?

Actress Kim Hee-ae (57) revealed that going to bed early is her only self-care method.

On the 9th, a video titled "This is a top-notch management secret, Kim Hee-ae's must-keep routine~~" was posted on the YouTube channel "Oh Eun-young's Bucket List." In the video, Kim Hee-ae said, "When I see others managing themselves, I think they're really smart and wonder how they know and do it so well," adding, "I don't know anything," showing a passive attitude toward management. When host Dr. Oh Eun-young asked, "So, what is something you definitely don't miss and always manage?" she replied, "Going to bed early, for sure," and "I don't go past 10 PM." Kim Hee-ae also added, "I'm not interested in skin care, but I do it because I think it's the minimum duty I owe as part of my profession." Is going to bed early like Kim Hee-ae really good for the skin? Both the amount and quality of sleep are related to skin health.

During sleep, various hormones are secreted in our bodies. In particular, attention should be paid to growth hormone. Generally, growth hormone is known to be related to height, but after the growth period, it helps with cell regeneration and fatigue relief, and hyaluronic acid, a moisturizing substance in the body, helps attract water molecules to the skin. This is why skin appears moist and glossy after a good night's sleep.

Not only growth hormone but also immune hormones secreted during sleep play a major role in maintaining skin health. When the body's circadian rhythm is disrupted due to lack of sleep and internal functions decline, immunity to diseases weakens, making it easier to become infected by external stimuli. Therefore, this can cause skin troubles like pimples or dullness, leading to makeup not adhering properly.

The sleep hormone melatonin begins to be secreted as you fall asleep and becomes most active around 2 a.m., during the deep sleep stage. In addition to inducing sleep, melatonin also reduces the function of pigment cells, helping to make the skin appear whiter. Therefore, if you do not get enough deep sleep during this time, your skin may become rough and your complexion darker. It is recommended to get an average of 7 to 8 hours of sleep per day and to fall asleep around 10 p.m.

The quality of sleep is also important. In fact, a study captured signs of skin aging in people with poor sleep quality and proved that they recover more slowly from UV rays and external environmental stress. Conversely, it was also found that people with good sleep quality recover stressed skin more efficiently. An ideal balance is maintaining deep sleep and light sleep in a ratio of about 3 to 1, and if you find it difficult to wake up in the morning despite sleeping for a long time, you should check the quality of your sleep.

Sleep posture and sleep environment management also have a significant impact on the skin. If the pillow is too high, it can worsen neck wrinkles and hinder blood circulation, leading to facial swelling, so it should not be too high, and the body and head should be kept relatively level. Additionally, dirty pillows that harbor bacteria can cause skin troubles, so pillows should be kept clean. It is advisable to use a cotton towel underneath and change it frequently, or to wash pillowcases regularly.
