불면증을 개선하기 위해 멜라토닌, ASMR, 수면제 등을 사용해보신 적이 있을 거예요. 그때는 잠시 도움이 되기도 합니다. 하지만 이런 방법들은 말 그대로 ‘보조 수단’일 뿐, 수면의 질을 근본적으로 개선하지는 못합니다. 진짜 중요한 건 ‘더 잘 자려고 애쓰는 것’이 아니라, 내 몸의 습관과 생각을 바꾸는 것입니다. 한번 떠올려보세요. 예전에 잘 자던 시절, 잠들기 위해 특별히 노력했었나요? 아마 아니었을 거예요.
 그냥 누우면, 어느새 자연스럽게 잠이 들었을 겁니다. 이처럼, 잠이란 원래 억지로 만들어내는 것이 아니라, 몸과 마음이 스스로 잠들 수 있는 환경을 만들어주는 것입니다. 루미는 바로 그 지점에 집중합니다. ― 이런 분들께 추천드려요 - 멜라토닌이나 수면제에 의존하지 않고 잠들고 싶은 분 - 잠에 드는게 어려우신 분 - 잠은 자는데 개운하지 않고, 자주 깨는 분 - ‘잘 자야 한다’는 압박 때문에 오히려 잠이 더 어려운 분 - 내 수면 상태를 제대로 이해하고, 근본적으로 수면을 개선하고 바꾸고 싶은 분 ― 루미의 주요 기능 ▶ 수면 심리학 원리 기반 프로그램 수면을 방해하는 생각과 습관을 점검하고,
내 몸에 맞는 수면 루틴을 제안합니다. ▶ 나의 수면 상태를 파악하는 수면 설문 현재 수면 상태와 방해 요인을 체계적으로 확인할 수 있어요. ▶ 매일 작성하는 수면 일지 잠든 시간, 깬 시간, 수면의 질을 기록하며
내 수면 패턴을 눈으로 확인합니다. ▶ 수면 리포트로 한눈에 보는 변화 수면 효율과 흐름을 점수와 그래프로 확인하고,
지금 상태에 맞는 피드백을 받아보세요. ― 잠을 ‘관리’하지 말고, 다시 ‘맡겨보세요’ 루미는 잠을 통제하려 하지 않습니다. 대신, 잠이 자연스럽게 찾아올 수 있도록 몸과 마음을 원래의 상태로 되돌려줍니다. 루미와 함께,
아무 걱정 없이 잠들던 그때로 돌아가요. ― *Morin CM, et al. JAMA. 2009;301(19):2005-2015 **Glass J, et al. BMJ. 2005;331(7526):1169 ***Jacobs GD, et al. Arch Intern Med. 2004;164(17):1888-1896 ― 이용약관(Terms of Use): https://lumisleep.app/terms 개인정보처리방침(Privacy Policy): https://lumisleep.app/privacy

What kind of turtle is your posture? One side photo answers in sixty seconds. THE SIXTY-SECOND TECH NECK TEST No sign-up. You get a posture score and the turtle your posture makes: Phone Navigator, Monitor Explorer, Perfect Balance Master. Keep it as a card and send it to a friend. Spend the day in front of a screen and your neck is the first thing to drift forward. Shellog wakes it up in seven minutes a day. Scute is the turtle your posture makes: every class you finish straightens him a little and lands a plate on his shell. TWO THINGS A DAY A ten-second body check and one short class. Fill both and the day is done; your first activity of the day adds a plate. Seven plates make a week, three fill it, and every day you show up your streak grows. CLASSES COME IN SERIES Tech Neck Reset with Scute and Open Up Rounded Shoulders with Somi, five classes each, seven minutes per class. A pelvis series with Pelvy is on the way. Shellog picks your next class for you. ONCE A WEEK, A POSTURE CHECK-IN Two photos, front and side, in about a minute. You get a score with a one-word read, the change since last time, and a ring for each area: neck, shoulders and pelvis. Scute takes on your posture, and your next series is chosen from it. A POND WITH FRIENDS Your friends' turtles live on your home screen, and a small star shows who showed up today. You see how each other stand, and a tap sends one nudge. A weekly pond ranking counts plates, not scores, and first place wins one thing: a golden lily pad next week. A BODY-CHECK TIMELAPSE One selfie a day from the same angle, and a month becomes a single card. Your selfies stay on your phone. A REMINDER, ONLY IF YOU WANT ONE After your first class of the day, one tap sets a daily reminder. If you used BodyBalancer: posture check-ins continue, and your past measurements stay at bodybalancer.app. Shellog is not a medical device and does not diagnose, treat, cure, or prevent any medical condition.
