《邪客篇》帝曰∶夫邪气之客人也，或令人目不瞑不卧出者，何气使然？伯高曰∶五
谷入于胃也，其糟粕、津液、宗气分为三隧，故宗气积于胸中，出于喉咙，以贯心脉而行呼
吸焉。营气者，泌其津液，注之于脉，化以为血，以荣四末，内注五脏六腑，以应刻数焉。
卫气者，出其悍气之 疾，而先行于四末分肉皮肤之间而不休者也。昼行于阳，夜行于
阴，常从足少阴之分间，行于五脏六腑。今厥气客于五脏六腑，则卫气独卫其外，行于阳，
不得入于阴。行于阳则阳气盛，阳气盛则阳跷陷；不得入于阴，阴虚，故目不瞑。帝曰∶善
。治之奈何？伯高曰∶补其不足，泻其有余，调其虚实，以通其道而去其邪，饮以半夏汤一
剂，阴阳已调，其卧立至。
《大惑论》帝曰∶病不得卧者，何气使然？岐伯曰∶卫气不得入于阴，常留于阳。留
于阳则阳气满，阳气满则阳跷盛，不得入于阴则阴气虚，故目不瞑矣。帝曰∶病目而不得视
者，何气使然？岐伯曰∶卫气留于阴，不得行于阳。留于阴则阴气盛，阴气盛则阴跷满，不
得入于阳则阳气虚，故目闭矣。帝曰∶人之多卧者，何气使然？岐伯曰∶此人肠胃大而皮肤
湿，而分肉不解焉。肠胃大则卫气留久，皮肤湿则分肉不解，其行迟。夫卫气者，昼日常行
于阳，夜行于阴，故阳气尽则卧，阴气尽则寤。故肠胃大，则卫气行留久；皮肤湿，分肉不
解，则行迟，留于阴也久，其气不清，则欲瞑，故多卧矣。其肠胃小，皮肤滑以缓，分肉解
利，卫气之留于阳也久，故少瞑焉。帝曰∶其非常经也，卒然多卧者，何气使然？岐伯曰∶
邪气留于上焦，上焦闭而不通，已食若饮汤，卫气留久于阴而不行，故卒然多卧焉。帝曰∶
善。治此诸邪奈何？岐伯曰∶先其脏腑，诛其小过，后调其气，盛者泻之，虚者补之，必先
明知其形志之苦乐，定乃取之。
《口问篇》帝曰∶人之欠者，何气使然？岐伯曰∶卫气昼日行于阳，夜半则行于阴，
阴者主夜，夜者卧。阳者主上，阴者主下，故阴气积于下，阳气未尽，阳引而上，阴引而下
，阴阳相引，故数欠。阳气尽，阴气盛，则目瞑，阴气尽而阳气盛，则寤矣。泻足少阴，补
足太阳。
《寒热病篇》曰∶阴跷、阳跷，阴阳相交，阳入阴，阴出阳，交于目锐 ，阳气盛则
目，阴气盛则瞑目。
《卫气行篇》曰∶平旦阴尽，阳气出于目，目张则气上行于头，夜行于阴，则复合于目
，故为一周。
《营卫生会篇》曰∶夜半为阴陇，夜半后而为阴衰，平旦阴尽而阳受气矣。日中为阳陇
，日西而阳衰，日入阳尽而阴受气矣。夜半而大会，万民皆卧，命曰合阴，平旦阴尽而阳受
气，如是无已，与天地同纪。帝曰∶老人之不夜瞑者，何气使然？少壮之人不昼瞑者，何气
使然？岐伯曰∶壮者之气血盛，则肌肉滑，气道通，营卫之行不失其常，故昼精而夜瞑。老
者之气血衰，其肌肉枯，气道涩，五脏之气相搏，其营气衰少而卫气内伐，故昼不精，夜不
瞑。
《水热穴论》曰∶故水病下为 肿大腹，上为喘呼，不得卧者，标本俱病。
《评热病论》曰∶不能正偃者，胃中不和也。正偃则咳甚，上迫肺也。诸水病者，故不
得卧，卧则惊，惊则咳甚也。
《太阴阳明论》曰∶犯贼风虚邪者，阳受之；饮食不节，起居不时者，阴受之。阳受之
则入六腑，阴受之则入五脏。入六腑则身热不时卧，上为喘呼；入五脏则 满闭塞，下
为飧泄，久为肠 。
《逆调论》曰∶不得卧而息有音者，是阳明之逆也，足三阳者下行，今逆而上行，故息
有音也。阳明者，胃脉也，胃者六腑之海，其气亦下行，阳明逆不得从其道，故不得卧也。
《下经》曰∶胃不和则卧不安。此之谓也。夫不得卧，卧则喘者，是水气之客也。夫水者，
循津液而流也，肾者水脏，主津液，主卧与喘也。帝曰∶人之不得偃卧者何也？岐伯曰∶肺
者，脏之盖也，肺气盛则脉大，脉大则不得偃卧。

《灵枢·邪客篇》黄帝问道：邪气侵入人体，有的使人眼睛闭不上、无法入睡，这是什么气机作用导致的？伯高回答说：五谷进入胃中，其糟粕、津液、宗气分为三条通道运行，所以宗气积聚在胸中，出于喉咙，贯通心脉而主持呼吸。营气，分泌津液，注入脉中，化生为血液，以濡养四肢末端，向内灌注五脏六腑，以应合昼夜刻漏之数。卫气，发出其剽悍滑疾之气，先行于四肢、分肉和皮肤之间，不停歇地运行。白天行于阳分，夜晚行于阴分，常从足少阴经的分野间，运行于五脏六腑。现在厥逆之气客居于五脏六腑，则卫气独自护卫于体表，行于阳分，不能进入阴分。行于阳分则阳气盛，阳气盛则阳跷脉满盛；不能进入阴分，则阴气虚，所以眼睛闭不上。黄帝说：好。怎么治疗呢？伯高说：补其不足，泻其有余，调和虚实，疏通其道并祛除邪气，服用半夏汤一剂，阴阳调和，睡眠立刻就能恢复。
《灵枢·大惑论》黄帝问道：患病不能入睡的，是什么气机作用导致的？岐伯说：卫气不能进入阴分，常停留在阳分。停留在阳分则阳气满盛，阳气满盛则阳跷脉盛，不能进入阴分则阴气虚，所以眼睛闭不上。黄帝问道：患病眼睛睁不开看东西的，是什么气机作用导致的？岐伯说：卫气停留在阴分，不能行于阳分。停留在阴分则阴气盛，阴气盛则阴跷脉满盛，不能进入阳分则阳气虚，所以眼睛闭合。黄帝问道：人之所以多睡的，是什么气机作用导致的？岐伯说：这个人肠胃较大且皮肤湿润，分肉不解利。肠胃大则卫气停留时间长，皮肤湿则分肉不解利，卫气运行迟缓。卫气，白天常行于阳分，夜晚行于阴分，所以阳气尽时则睡觉，阴气尽时则醒来。因此肠胃大，卫气停留时间长；皮肤湿，分肉不解利，则运行迟缓，停留在阴分的时间久，其气不清爽，就想睡觉，所以多睡。如果肠胃小，皮肤滑润舒缓，分肉解利，卫气在阳分停留的时间久，所以睡得少。黄帝问道：如果不属于常规经脉病变，突然多睡的，是什么气机作用导致的？岐伯说：邪气停留在上焦，上焦闭塞不通，刚吃过饭或喝过汤，卫气长时间停留在阴分而不能运行，所以突然多睡。黄帝说：好。治疗这些邪气引起的病症怎么办？岐伯说：先察脏腑，纠正小的过失，然后调畅气机，实证用泻法，虚证用补法，必须先明确病人的形体与情志的苦乐状况，确定后取穴治疗。
《灵枢·口问篇》黄帝问道：人打哈欠的，是什么气机作用导致的？岐伯说：卫气白天行于阳分，半夜则行于阴分，阴分主夜间，夜间主睡眠。阳分主上部，阴分主下部，所以阴气积聚在下部，阳气未尽，阳气牵引向上，阴气牵引向下，阴阳相互牵引，所以频繁打哈欠。阳气尽，阴气盛，则眼睛闭合睡觉；阴气尽而阳气盛，则醒来。治疗时泻足少阴经，补足太阳经。
《灵枢·寒热病篇》说：阴跷脉、阳跷脉，阴阳相交，阳入阴，阴出阳，交汇于目外角，阳气盛则眼睛睁开，阴气盛则眼睛闭合。
《灵枢·卫气行篇》说：清晨阴气尽，阳气出于目，眼睛张开则气上行于头，夜晚行于阴分，则又复合于目，所以为一周。
《灵枢·营卫生会篇》说：半夜为阴气隆盛，半夜过后阴气衰退，清晨阴气尽而阳气受气。日中为阳气隆盛，日落西山阳气衰退，日落阳气尽而阴气受气。半夜阴阳大会，万民皆卧，称为合阴，清晨阴气尽而阳气受气，如此循环不已，与天地运行的规律相同。黄帝问道：老人晚上不睡觉的，是什么气机作用导致的？青壮年白天不睡觉的，是什么气机作用导致的？岐伯说：壮年人气血旺盛，肌肉滑利，气道通畅，营卫的运行不失常态，所以白天精神饱满，晚上能入睡。老年人气血衰弱，肌肉枯槁，气道涩滞，五脏之气相搏结，其营气衰少而卫气内扰，所以白天精神不振，晚上睡不着。
《灵枢·水热穴论》说：所以水气病，下表现为腹部肿大，上表现为喘息呼叫，不能平卧的，是标本都病了。
《素问·评热病论》说：不能正身仰卧的，是胃中不和。正身仰卧则咳嗽加重，气上迫于肺。所有的水气病患者，所以不能平卧，平卧则惊恐，惊恐则咳嗽加重。
《素问·太阴阳明论》说：遭受贼风虚邪侵袭的，阳经受之；饮食不节制，起居不规律的，阴经受之。阳经受邪则传入六腑，阴经受邪则传入五脏。传入六腑则身体发热，不时失眠，气上逆为喘息呼叫；传入五脏则脘腹胀满闭塞，下表现为完谷不化的泄泻，日久发展为肠澼（痢疾）。
《素问·逆调论》说：不能平卧且呼吸有声音的，这是阳明经气逆乱所致，足三阳经气本应下行，现在逆而上行，所以呼吸有声音。阳明经，是胃的经脉，胃是六腑的海，其气也下行，阳明经气逆乱不能顺从其正道，所以不能平卧。
《下经》说：胃不和则卧不安。说的就是这种情况。至于不能平卧，平卧则喘息的，是水气邪客所致。水，是顺着津液流动的，肾是水脏，主管津液，同时也主管睡眠与喘息。黄帝问道：人不能仰面躺着的，是什么原因？岐伯说：肺，是五脏的华盖，肺气盛则脉大，脉大则不能仰面躺着。

In the *Xieke Pian* chapter of *Ling Shu*, the Yellow Emperor asked: When pathogenic factors invade the human body, why do some people suffer from inability to close their eyes and insomnia? Bo Gao replied: When five grains enter the stomach, their dregs, fluids, and Zong Qi (Gathering Qi) are distributed through three pathways. Thus, Zong Qi accumulates in the chest, emerges from the throat, penetrates the Heart vessels, and governs respiration. Ying Qi (Nutritive Qi) secretes its fluids, injects them into the vessels, transforms them into blood, and thereby nourishes the four extremities while internally irrigating the Five Zang and Six Fu organs, corresponding to the temporal cycles of the day and night. Wei Qi (Defensive Qi) issues its fierce, rapid, and slippery qi, proceeding first among the four extremities, muscle intervals, and skin without rest. It travels in the Yang aspects during the day and in the Yin aspects at night, often passing through the areas of the Foot Shaoyin meridian to circulate among the Five Zang and Six Fu organs. Now, if Jue Qi (Rebellious Qi) lodges in the Five Zang and Six Fu organs, Wei Qi alone guards the exterior, traveling in the Yang aspects, and cannot enter the Yin aspects. Traveling in the Yang aspects causes Yang Qi to become excessive; when Yang Qi is excessive, the Yang Qiao vessel becomes full. Inability to enter the Yin aspects leads to Yin deficiency; therefore, the eyes remain open. The Yellow Emperor said: Excellent. How should it be treated? Bo Gao said: Tonify what is insufficient, drain what is excessive, regulate deficiency and excess, unblock the pathways, and expel the pathogen. Administer one dose of Banxia Tang (Pinellia Decoction); once Yin and Yang are regulated, sleep will resume immediately.
In the *Dahuo Lun* chapter of *Ling Shu*, the Yellow Emperor asked: What qi mechanism causes illness-related insomnia? Qi Bo replied: When Wei Qi cannot enter the Yin aspects, it remains constantly in the Yang aspects. Remaining in the Yang aspects causes Yang Qi to be full; when Yang Qi is full, the Yang Qiao vessel becomes vigorous. Inability to enter the Yin aspects results in Yin Qi deficiency; thus, the eyes remain open. The Yellow Emperor asked: What qi mechanism causes illness-related inability to open the eyes and see? Qi Bo replied: When Wei Qi remains in the Yin aspects and cannot travel in the Yang aspects, remaining in the Yin aspects causes Yin Qi to be excessive; when Yin Qi is excessive, the Yin Qiao vessel becomes full. Inability to enter the Yang aspects results in Yang Qi deficiency; thus, the eyes remain closed. The Yellow Emperor asked: Why do some people sleep excessively? Qi Bo replied: This person has large intestines and stomach, and moist skin, with muscle intervals that are not loose. Large intestines and stomach cause Wei Qi to remain for a long time; moist skin means the muscle intervals are not loose, causing slow movement. Wei Qi usually travels in the Yang aspects during the day and in the Yin aspects at night; thus, when Yang Qi is exhausted, one sleeps, and when Yin Qi is exhausted, one wakes. Therefore, large intestines and stomach cause Wei Qi to remain for a long time; moist skin and tight muscle intervals cause slow movement, leading to prolonged stay in the Yin aspects. If the qi is not clear, one feels sleepy and sleeps excessively. Conversely, small intestines and stomach, smooth and relaxed skin, and loose muscle intervals allow Wei Qi to remain in the Yang aspects for a long time, resulting in less sleep. The Yellow Emperor asked: If it is not a regular meridian pathology, but sudden excessive sleeping occurs, what is the qi mechanism? Qi Bo replied: Pathogenic factors remain in the Upper Jiao (Upper Burner), causing blockage and obstruction there. After eating or drinking soup, Wei Qi remains in the Yin aspects for a long time and cannot move, causing sudden excessive sleeping. The Yellow Emperor said: Excellent. How should these pathogenic conditions be treated? Qi Bo replied: First examine the Zang and Fu organs, correct minor errors, then regulate the Qi. For excess conditions, use draining methods; for deficiency conditions, use tonifying methods. One must first clearly understand the physical and emotional states of the patient before selecting acupoints.
In the *Kouwen Pian* chapter of *Ling Shu*, the Yellow Emperor asked: What qi mechanism causes yawning? Qi Bo replied: Wei Qi travels in the Yang aspects during the day and enters the Yin aspects at midnight. Yin governs the night, and the night governs sleep. Yang governs the upper part, and Yin governs the lower part. Thus, Yin Qi accumulates in the lower part, while Yang Qi is not yet exhausted. Yang pulls upward, and Yin pulls downward; the mutual attraction of Yin and Yang causes frequent yawning. When Yang Qi is exhausted and Yin Qi is excessive, the eyes close for sleep; when Yin Qi is exhausted and Yang Qi becomes excessive, one wakes. Treatment involves draining the Foot Shaoyin meridian and tonifying the Foot Taiyang meridian.
The *Hanche Bing Pian* chapter of *Ling Shu* states: The Yin Qiao and Yang Qiao meridians intersect; Yang enters Yin, and Yin exits Yang, meeting at the outer canthus of the eye. When Yang Qi is excessive, the eyes open; when Yin Qi is excessive, the eyes close.
The *Weiqi Xing Pian* chapter of *Ling Shu* states: At dawn, Yin Qi is exhausted, and Yang Qi emerges from the eyes. When the eyes open, Qi moves upward to the head; at night, it travels in the Yin aspects and reunites at the eyes, completing one cycle.
The *Yingwe Huihe Pian* chapter of *Ling Shu* states: Midnight is the peak of Yin Qi; after midnight, Yin Qi declines. At dawn, Yin Qi is exhausted, and Yang Qi receives Qi. Noon is the peak of Yang Qi; at sunset, Yang Qi declines. At sunset, Yang Qi is exhausted, and Yin Qi receives Qi. At midnight, there is a great convergence, and all people sleep, called "He Yin" (Union of Yin). At dawn, Yin Qi is exhausted, and Yang Qi receives Qi. This cycle continues endlessly, mirroring the rhythms of heaven and earth. The Yellow Emperor asked: What qi mechanism causes the elderly to be unable to sleep at night? And what causes the young and strong to be unable to sleep during the day? Qi Bo replied: In vigorous people, Qi and Blood are abundant, muscles are smooth, airways are patent, and the circulation of Ying and Wei Qi follows normal patterns; thus, they are alert during the day and sleep soundly at night. In the elderly, Qi and Blood decline, muscles become withered, airways become obstructed, and the Qi of the Five Zang organs clashes. Ying Qi becomes deficient, and Wei Qi rebels internally; thus, they lack alertness during the day and cannot sleep at night.
The *Shuire Xuelun* chapter of *Ling Shu* states: Water diseases manifest as abdominal swelling below and wheezing/calling above, with an inability to lie flat, indicating that both the root and branch are diseased.
The *Ping Re Bing Lun* chapter of *Su Wen* states: Inability to lie supine indicates disharmony in the Stomach. Lying supine exacerbates coughing due to pressure on the Lungs. All water disease patients cannot lie flat; lying flat causes fright, which exacerbates coughing.
The *Taiyin Yangming Lun* chapter of *Su Wen* states: Invasion by thief-wind and empty pathogens affects the Yang meridians; irregular diet and lifestyle affect the Yin meridians. Pathogens entering the Yang meridians transmit to the Six Fu organs; those entering the Yin meridians transmit to the Five Zang organs. Transmission to the Six Fu organs causes fever and frequent insomnia, with rebellious Qi causing wheezing; transmission to the Five Zang organs causes abdominal fullness and obstruction, with diarrhea of undigested food below, potentially developing into intestinal dysentery over time.
The *Nidiao Lun* chapter of *Su Wen* states: Inability to lie flat accompanied by noisy breathing indicates rebellion of the Yangming Meridian. The Foot Three Yang meridians normally descend; now they rebel and ascend, causing noisy breathing. The Yangming Meridian is the Stomach meridian; the Stomach is the sea of the Six Fu organs, and its Qi also descends. Rebellion of Yangming Qi prevents it from following its proper pathway, causing inability to lie flat.
The *Xia Jing* states: Disharmony of the Stomach leads to restless sleep. This refers to the aforementioned condition. As for inability to lie flat and wheezing upon lying down, this is caused by the invasion of Water Qi. Water flows along the Jin Ye (Body Fluids). The Kidney is the Water Organ, governing Jin Ye, and also governs sleep and wheezing. The Yellow Emperor asked: What causes the inability to lie supine? Qi Bo replied: The Lungs are the canopy of the Zang organs. When Lung Qi is excessive, the vessels become large; when vessels are large, one cannot lie supine.
