누우면 잡생각 때문에 잠을 설쳐요: 혹시 뇌가 '과부하' 상태인가요?

Hello. This is Dalimchae Korean Medicine Clinic. # Trouble Sleeping Due to Racing Thoughts When Lying Down: Is Your Brain Overloaded? When night comes, you want to lie in bed and fall asleep comfortably, but have you ever experienced tossing and turning with your head full of racing thoughts? Thoughts like "Why did I act like that today?", "What do I need to do tomorrow?", or "I shouldn't have said that back then" chain together, making it difficult to fall asleep. This is a problem many people relate to. It's not just about being too tired to sleep; the harder you try to sleep, the more alert and anxious your mind becomes, creating a vicious cycle. This symptom is a form of 'insomnia' commonly seen in modern society, and it often stems from an imbalance in the brain and autonomic nervous system. 💡 **Key Answer** Top 3 most common causes of "Trouble Sleeping Due to Racing Thoughts When Lying Down": ① Autonomic nervous system imbalance causing excessive brain arousal ② Psychological tension due to stress and anxiety ③ Sleep-inducing hormone imbalance and sleep pattern disruption Dalimchae Korean Medicine Clinic relieves brain overload and helps you regain deep sleep through **autonomic stabilization** treatment. ## Is sleepless nights just caused by being 'tired'? Insomnia is a complex problem that cannot be explained solely by physical fatigue. Many people think, "Wasn't I tired today?" when they can't sleep, but in reality, the body is tired while the brain is unable to rest—an 'overloaded' state. The core system regulating our body's sleep and wakefulness is the 'autonomic nervous system'. Composed of the sympathetic and parasympathetic nervous systems, the sympathetic nervous system handles activity and tension, while the parasympathetic nervous system handles rest and relaxation. For healthy sleep, the parasympathetic nervous system should become active at night to comfortably relax body and mind. However, when chronic stress, irregular lifestyle habits, or excessive smartphone use continuously hyperactivates the sympathetic nervous system, the brain remains in a state of tension even when lying in bed. Heart Rate Variability (HRV) tests can objectively confirm this autonomic imbalance, and prominent sympathetic hyperactivation tends to appear in insomnia patients. Since the brain cannot release tension, racing thoughts increase and falling asleep becomes difficult. This is like the brain keeping the 'warning light' on without taking proper rest. ## What is the scientific basis for Oriental medical insomnia treatment? In Oriental medicine, insomnia is not viewed merely as a sleep problem, but is deeply connected to the balance of the five viscera and six entrails, qi and blood circulation, and the stability of the mind and spirit (心神). Recent clinical studies also reveal that Oriental medical treatment shows meaningful effects in improving insomnia. In a randomized controlled clinical study by Guo J et al., published in the journal *Evid Based Complement Alternat Med* in 2013, 180 primary insomnia patients underwent acupuncture treatment for 6 weeks. Both the acupuncture group and the sleeping pill group (estazolam) showed significant improvements in PSQI (Pittsburgh Sleep Quality Index) scores evaluating sleep quality. The researchers concluded that acupuncture is effective in improving sleep quality and daytime functioning in insomnia patients, showing efficacy comparable to drug treatment. These results suggest that acupuncture can positively impact insomnia through the stabilization of the brain and nervous system. Furthermore, a recent clinical trend study on Cheonwangbosim-dan (天王補心丹) published in *Yaksa Gongron* in 2026 supports the effectiveness of herbal medicine treatment. This meta-analysis analyzed treatment effects using Cheonwangbosim-dan in 1,256 insomnia patients across 14 studies. The results showed that Cheonwangbosim-dan was beneficial in reducing sleep onset latency in patients, and showed exceptional effects especially in anxiety alleviation. The study evaluated safety as secured, with only 1 case of minor side effect reported during monotherapy or combination with Western medicine. Dalimchae Korean Medicine Clinic Songdo Branch reduces brain overload and induces deep sleep through customized Oriental medical treatments based on these scientific treatment principles, tailored to each patient's symptoms and constitution. ## How does Dalimchae Korean Medicine Clinic's 'Autonomic Stabilization' treatment relieve brain overload? At Dalimchae Korean Medicine Clinic, we view the root cause of insomnia where racing thoughts prevent sleep when lying down as 'autonomic nervous system imbalance' and the resulting 'brain hyperactivation'. Our brain processes a lot of information and stimuli during the day, but at night, it needs to rest and recharge sufficiently. However, when autonomic balance collapses, the brain cannot rest and continuously maintains a tension state—much like an overheated engine running continuously without time to cool down. Dalimchae Korean Medicine Clinic's 'autonomic stabilization' treatment focuses on relieving this brain overload and creating an environment where the body can comfortably fall asleep on its own. This aligns with the Oriental medicine principle of 'Su Seung Hwa Gang' (Water Up, Fire Down). Hot energy gathered in the head (Fire) is lowered, and cool energy (Water) is raised to smooth systemic circulation, cooling brain heat and restoring autonomic balance. Treatment proceeds in the following directions: * Customized Herbal Medicine: Considering the patient's constitution, insomnia type, and accompanying symptoms (anxiety, agitation, indigestion, etc.), we prescribe herbal medicine that lowers nervous system heat, calms the mind, and supplies sufficient nourishment to the brain. For instance, for types with many racing thoughts, anxiety, and difficulty falling asleep, prescriptions addressing Xin-Dan Deficiency (心膽虛怯) are utilized to stabilize mind and spirit and induce deep sleep. * Acupuncture Treatment: Inserting needles into specific acupuncture points regulates autonomic nervous system balance and calms brain hyper-arousal. In particular, points effective for insomnia such as Shenmen (神門), Sanyinjiao (三陰交), and Baihui (百會) contribute to sleep-inducing hormone secretion and brain wave stabilization, helping comfortable sleep. Recent studies show electroacupuncture significantly improves sleep efficiency and anxiety/depression scales. * Lifestyle Correction and Counseling: Through sleep hygiene education, we remove sleep-disrupting elements and help patients regulate their autonomic nerves independently through stress management and relaxation training. This combined Oriental medical treatment focuses not on forcibly inducing sleep, but on normalizing the body's system so that the body can achieve comfortable sleep on its own. In particular, we provide effective solutions to those visiting **Songdo Insomnia Clinic** who want to sleep but whose brains won't stop racing. ## Am I Also Suffering from Autonomic Insomnia? Symptom Checklist Check the following items. If 3 or more apply, suspect autonomic insomnia due to brain overload and consider active treatment. * When lying in bed, thoughts about the day's events or future tasks arise, making it hard to fall asleep. * There is a lot of worry and anxiety, making it hard to feel at ease before sleeping. * Waking up frequently at night, and once awake, taking a long time to fall back asleep. * Dreaming a lot and remembering dreams vividly, making mornings feel unrefreshed. * Experiencing severe daytime fatigue, poor concentration, and easy irritation. * Frequently accompanied by headaches, dizziness, indigestion, heart palpitations, or neck/shoulder stiffness. * Easily waking up and becoming sensitive to small noises or lights. * Taking sleeping pills has no effect, or tolerance builds up requiring increased dosage. **When 3 or more apply:** Suspect insomnia due to autonomic imbalance. Professional consultation at **Songdo Autonomic Clinic** is recommended. **When 5 or more apply:** Brain overload is severe. Immediate clinic visit and intensive management through combined Oriental treatment are required. ## FAQ **Q. Is it psychological when I can't sleep due to racing thoughts when lying down?** A. Psychological factors play a significant role, but it cannot be viewed solely as a psychological problem. Excessive stress or anxiety stimulates the brain's autonomic nervous system, hyperactivating sympathetic nerves, which maintains brain arousal, induces racing thoughts, and makes falling asleep difficult. Therefore, restoring autonomic balance along with psychological stability is important. **Q. Can insomnia heal naturally?** A. Insomnia caused by temporary stress or environmental changes can naturally improve with sufficient rest and lifestyle improvements. However, chronic insomnia lasting over a month or disrupting daily life is hard to heal naturally, and if left untreated, can lead to other health issues like depression, anxiety disorders, and weakened immunity, so professional help is advised. **Q. Can insomnia be treated without taking sleeping pills?** A. Yes, Dalimchae Korean Medicine Clinic aims to treat insomnia without sleeping pill use. Unlike sleeping pills, Oriental medical treatments like herbal medicine, acupuncture, and pharmacopuncture help restore natural sleep patterns by healing the brain and autonomic nervous system without dependency or tolerance issues. This is a great alternative for those worried about sleeping pill side effects or finding no effect from sleeping pills. **Q. How long does insomnia treatment take at Songdo Clinic?** A. Insomnia treatment duration varies depending on individual symptom severity, onset duration, accompanying conditions, and lifestyle habits. Generally, symptom improvement is expected with about 3 months of steady treatment and management, followed by maintenance management to prevent recurrence.
