Waking up at Dawn: It's Not Aging, It's an Overheated Brain Warning

Do you have trouble falling asleep when you lie down at night, and even when you do fall asleep, you wake up in the early morning and suffer from the pain of not being able to sleep again? Are you dismissing it as "I'm just getting older" or "I must be tired"? While many people think waking up at dawn is just a matter of age or temporary condition, it is likely an SOS signal from an imbalance in the 'autonomic nervous system,' an important system in our body. Why can't our brain rest and keep waking up at night when it should be comfortable? Today, Dalimchae Clinic will tell you the real cause and fundamental solution for waking up at dawn.

💡 [Key Answer] The 3 most common causes of "waking up at dawn": ① Autonomic nervous system imbalance (Sympathetic nerve overactivity even at night) ② Fine over-arousal and heat symptoms in the brain ③ Lack of energy and soothing function in heart and brain cells Dalimchae Clinic creates a body that can fall into a deep sleep on its own by resolving brain overload through autonomic stabilization.

Insomnia, especially "sleep maintenance disorder" where one falls asleep but sleeps lightly and wakes up often, is deeply related to the imbalance of the autonomic nervous system, not just a problem with sleep. Our body's autonomic nervous system consists of the "sympathetic nervous system," which is responsible for activity and tension, and the "parasympathetic nervous system," which is responsible for rest and recovery. For healthy sleep, the parasympathetic nervous system should become dominant at night so that the body relaxes comfortably and the brain switches to rest mode. However, if stress, overwork, or anxiety persists, the sympathetic nervous system becomes excessively active even at night, and the brain maintains a state of tension.

In Korean medicine, this is also explained as a broken harmony of "Su-seung-hwa-gang (Rising Water and Descending Fire)." When an imbalance occurs where heat rises to the head (Fire) and the body becomes cold (Water), the brain becomes overheated and cannot rest properly at night. It is also a major cause that fine inflammatory reactions occur in brain cells, the fluidity of brain cell membranes decreases, and the sensitivity of GABA receptors decreases, so the "inhibitory signal" that maintains deep sleep does not last until the end. As these problems act complexly, one wakes up easily even at small noises or temperature changes, and the vicious cycle of having difficulty falling back asleep repeats.

Beyond sleep medications that simply force sleep, Korean medicine treatment, which helps the fundamental recovery of our body so that it can sleep deeply on its own, is being proven effective through various studies.

2021년 한국한의학연구원 이준환 박사 연구팀은 국내 4개 한의과대학 부속 한방병원과 진행한 다기관 임상연구에서 만성 불면증 환자에 대한 전침 치료 효과를 과학적으로 규명했습니다. 이 연구에서는 3개월 이상 불면으로 일상생활에 불편을 겪은 환자 150명을 대상으로 전침 치료군, 가짜 전침 치료군, 일상 관리군으로 나누어 실험을 진행했습니다. 그 결과, 전침 치료군의 ISI(불면증 심각도) 점수가 치료 전 평균 19.02점에서 치료 종료 후 10.13점까지 개선되었으며, 이는 통계적으로 유의미한 차이였습니다. 특히 치료 종료 4주 및 8주 후 추적 관찰 시 점수가 각각 8.60점과 8.02점으로 개선 효과가 지속되었고, 불면증에서 비롯된 불안과 우울 증세도 나아진 것으로 나타났습니다 (p<0.05). 연구진은 이러한 결과에 대해 전침 치료가 불면증 환자들에게 약물 치료의 좋은 대안이 될 수 있다고 결론지었습니다.

또한, 2022년 강동경희대학교한방병원 한방내과 윤성우 교수팀은 메타분석 연구를 통해 암 환자의 불면증에 대한 한약 치료의 효과와 안전성을 확인했습니다. 이 연구는 영어권 국가와 중국을 포함한 9개 데이터베이스에서 2020년 11월까지 발표된 논문 중 최종 14개를 선정하고 10개의 논문에 대해 메타분석을 수행했습니다. 연구 결과, 한약 치료가 수면의 질, 잠복기, 수면 시간 등을 평가하는 피츠버그 수면 질 지수(PSQI)에서 유의미한 개선 효과를 보였으며, 이는 졸피뎀, 에스타졸람, 디아제팜 등 수면제를 이용한 연구 8건과 비교했을 때도 통계적으로 유의미한 개선이었습니다 (p<0.05). 주로 산조인(酸棗仁)을 주약으로 하는 가미귀비탕(加味歸脾湯), 천왕보심단(天王보심단), 고본안신탕(固本安신탕) 등이 활용되었으며, 산조인의 유효성분이 억제성 신경전달물질인 GABA 수용체에 작용하여 수면 및 진정 효과를 나타낸다는 선행 비임상 연구 결과와도 부합합니다. 이는 한약 치료가 불면증의 근본적인 원인을 다스려 수면의 질을 개선하는 데 안전하고 효과적인 방법이 될 수 있음을 시사합니다.

Based on these data, Dalimchae Clinic Incheon Branch focuses on creating an environment where the brain can rest comfortably on its own by regaining the balance of the autonomic nervous system, rather than simply putting the patient to sleep. Since sleep maintenance disorders often occur due to a lack of "cooling water (Yin fluid)" in the brain or inflammation in the nervous system, the key is to cultivate the strength to maintain deep sleep by solving these problems.

Dalimchae Clinic does not view the symptom of "waking up at dawn" as a simple sleep problem, but understands it as a signal originating from the imbalance of an overheated brain and a collapsed autonomic nervous system and approaches fundamental treatment. Our brain and autonomic nervous system are like the engine of a car. Even when it should be resting at night, if the engine is continuously overheating, it is difficult to operate properly no matter how much fuel is filled.

This treatment has a positive effect not only on insomnia but also on various autonomic nervous system problems that are likely to appear with insomnia, such as headaches, dizziness, chronic fatigue, and anxiety.

Read the following items and check how many symptoms apply to you.

• It takes more than 30 minutes to fall asleep 3 or more times a week.
• I wake up at least twice after falling asleep and have trouble falling back asleep.
• If I wake up between 3 AM and 5 AM, I cannot fall back asleep and toss and turn.
• I don't feel refreshed after sleeping and feel tired and lethargic during the day.
• I often feel irritable and anxious even at routine things.
• I am experiencing physical symptoms such as headaches, indigestion, and chest tightness.
• Caffeine or smartphone use often continues until late at night.

Judgment Criteria:

• 2 or fewer items apply: It may be early-stage insomnia or a temporary sleep problem. Efforts to improve sleep habits and the quality of rest are needed.
• 3~4 items apply: Insomnia due to autonomic nervous system imbalance is suspected. It is recommended to consider combined Korean medicine treatment after precise diagnosis at Dalimchae Clinic, an Incheon insomnia clinic.
• 5 or more items apply: It is highly likely to be a chronic sleep maintenance disorder. Since the brain and autonomic nervous system may be significantly overloaded, it is important to visit immediately and get professional help.

Q. Is it unconditionally insomnia if I wake up at dawn? A. Waking up briefly at dawn and falling back asleep can be a normal part of sleep. However, if early morning awakening is repeated more than 3 times a week and interferes with daily life, such as fatigue and decreased concentration during the day, it can be diagnosed as insomnia, especially sleep maintenance disorder.

Q. Can insomnia be cured without sleeping pills? A. Yes, it is fully possible. Sleeping pills temporarily induce sleep, but they act to force the brain to calm down rather than solving the fundamental cause of insomnia. Dalimchae's autonomic stabilization treatment helps regain healthy sleep without sleeping pills in the long term by cultivating the body's strength to fall asleep on its own.

Q. How long does insomnia treatment take? A. The treatment period for insomnia varies depending on the severity of individual symptoms, chronicity, and physical condition. Generally, it takes steady treatment and effort to restore the balance of the autonomic nervous system and improve the body's function, and you will experience gradual improvement over several weeks to several months. Dalimchae Clinic Incheon Branch will establish an individual custom treatment plan.

Q. I also have anxiety and headaches, can they be treated together? A. Yes, that's right. Anxiety, headaches, and dizziness are common symptoms that accompany insomnia due to autonomic imbalance. Since Dalimchae's autonomic stabilization treatment treats the autonomic nervous system, which is the fundamental cause of these symptoms, both insomnia and accompanying symptoms can be integratedly improved.
