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。
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.
