夫邪气之客于人也，或令人目不得眠，何也？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，以贯心肺，而行呼吸焉。荣气者，泌其津液，注
之于脉也，化为血，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，昼行于阳，夜行于阴。其入于阴，常从足少
阴之分肉间，行于五脏六腑。今邪气客于脏腑，则卫气独营其外，行于阳，不得入于阴；行
于阳则阳气盛，阳气盛则阳跷满，不得入于阴，阴气虚，故目不得眠。
大病之后，脏腑尚虚，荣卫未和，故生于冷热。阴气虚，卫气独行于阳，不入于阴，故
不得眠。若心烦不得眠者，心热也；若但虚烦而不得眠者，胆冷也。
夫病后，经络既虚，受于风湿，肤腠闭塞，荣卫不利，气不宣泄，故致虚肿。虚肿不已
，津液涩，或变为微水也。
脉动而暂止，因不能还而复动，是脉结也。虚劳血气衰少，脉虽乘气而动，血气虚则不
能连属，故脉为之结也。
诸阳主表，在于肤腠之间。若阳气偏虚，则津液发泄，故为汗。汗多则损于心，心液为
汗。
诊其脉，寸口弱者，阳气虚，为多汗脉也。
盗汗者，因眠睡而身体流汗也。此由阳虚所致。久不已，令人羸瘠枯瘦，心气不足，亡
津液故也。
诊其脉，男子平人脉虚弱细微，皆为盗汗脉也。
邪气侵入人体，有时会导致人眼睛无法闭合、不能安睡，这是为什么呢？回答说：五谷进入胃中后，其糟粕、津液和宗气，分为三条通道运行。因此，宗气积聚在胸中，出于喉咙，贯通心肺，从而推动呼吸运动。营气，是分泌其津液，注入脉管之中，化生为血液，以濡养四肢末端，向内灌注五脏六腑，以配合呼吸的节律（古人将一夜分为五十刻，营气运行与之相应）。卫气，是发出其剽悍滑疾之气，先行运行于四肢末端、肌肉纹理和皮肤之间，昼夜不停息，白天行于体表之阳分，夜晚行于体内之阴分。当它进入阴分时，通常从足少阴肾经所主的分肉间开始，运行于五脏六腑。如今邪气客居于脏腑，导致卫气只能独自在外周运行，行于阳分，而不能进入阴分；卫气行于阳分则阳气偏盛，阳气盛则阳跷脉充盈满实，卫气因此无法进入阴分，导致阴气相对虚弱，所以眼睛无法闭合、不能安睡。
大病之后，脏腑仍然虚弱，营气和卫气尚未调和，因此产生忽冷忽热的症状。此时阴气虚弱，卫气独自运行于阳分，不进入阴分，所以不能安睡。如果心中烦乱且不能安睡，这是心热所致；如果只是虚烦而不能安睡，这是胆寒所致。
疾病初愈后，经络已经虚弱，又受到风湿之邪侵袭，导致皮肤腠理闭塞，营卫运行不畅，气机不能宣通宣泄，因此导致虚性浮肿。如果虚肿不止，津液运行涩滞，或者转变为轻微的水饮病。
脉搏跳动时有间歇，停顿片刻后不能立即恢复连续跳动，这就是结脉。虚劳病患者血气衰少，虽然脉搏随气机而动，但因血气虚弱不能相互连接延续，所以脉搏出现结代现象。
诸阳经主司体表，位于皮肤腠理之间。如果阳气偏虚，则津液外泄，从而导致出汗。汗出过多则会损伤心脏，因为心之液为汗。
诊察患者的脉搏，如果寸口脉弱，说明阳气虚弱，这是多汗症的脉象。
盗汗，是指在睡眠中身体流出汗液的现象。这是由于阳虚所致。长期不愈，会使人消瘦枯瘦，心气不足，以及津液亡失的缘故。
诊察患者的脉搏，男子在平人（健康状态）下若脉象虚弱细微，都是盗汗的脉象。
When pathogenic factors invade the human body, they may cause insomnia (inability to sleep). Why is this? It is said that when grains enter the stomach, their dregs, body fluids (Jinye), and Zong Qi (Gathering Qi) are divided into three pathways. Thus, Zong Qi accumulates in the chest, emerges from the throat, penetrates the Heart and Lungs, and governs respiration. Ying Qi (Nutritive Qi) secretes its body fluids, injects them into the vessels, transforms them into blood, nourishes the four extremities, and internally irrigates the five zang organs and six fu organs, corresponding to the time divisions of the day and night. Wei Qi (Defensive Qi) releases its fierce, rapid, and slippery qi, moving first among the four extremities, muscle intervals, and skin pores without rest; it travels on the exterior (Yang) during the day and on the interior (Yin) at night. When entering Yin, it usually proceeds between the muscle intervals governed by Foot-Shaoyin Kidney channel, circulating through the five zang organs and six fu organs. Now, if pathogenic factors lodge in the zang and fu organs, Wei Qi alone circulates externally, traveling on Yang, and cannot enter Yin; traveling on Yang leads to an excess of Yang qi, causing fullness in the Yang Qiao vessel, preventing entry into Yin, resulting in deficiency of Yin qi, hence the inability to close the eyes and sleep.
After a severe illness, the zang and fu organs remain deficient, and Ying and Wei Qi are not yet harmonized, thus generating sensations of alternating cold and heat. With Yin qi deficient, Wei Qi travels alone on Yang and does not enter Yin, leading to insomnia. If there is mental restlessness accompanied by insomnia, it is due to Heat in the Heart; if there is only empty restlessness with insomnia, it is due to Cold in the Gallbladder.
After recovery from illness, the meridians and collaterals are already deficient, susceptible to Wind-Dampness, causing closure of the skin and pores, hindering the smooth flow of Ying and Wei Qi, and preventing the venting of Qi, thereby leading to edema. If the edema persists, body fluids become stagnant, potentially transforming into mild fluid retention.
A pulse that beats intermittently and pauses temporarily, failing to resume immediately after the pause, is known as a Knotted Pulse (Jie Mai). In consumptive disorders, blood and Qi are depleted; although the pulse moves with Qi, the deficiency of blood and Qi prevents continuity, causing the pulse to knot.
All Yang channels govern the exterior, located in the skin and pores. If Yang Qi is relatively deficient, body fluids leak out, resulting in sweating. Excessive sweating damages the Heart, as the fluid of the Heart is sweat.
Upon palpating the pulse, if the Cun Kou (Inch position at the radial artery) is weak, it indicates deficiency of Yang Qi, which is the pulse pattern for excessive sweating.
Night sweats refer to sweating during sleep. This is caused by deficiency of Yang. If prolonged, it causes emaciation and thinning, insufficiency of Heart Qi, and loss of body fluids.
Upon palpating the pulse, in men who are otherwise healthy, a weak, fine, and subtle pulse indicates night sweats.
