《素问》云∶春三月，此谓发陈，天地俱生，万物以荣，夜卧蚤起，广步于庭，被发缓
形，以使志生，生而勿杀，与而勿夺，赏而勿罚，此春气之应也。养生之道也。
夏三月，此谓蕃秀，天地气交，万物华实，夜卧早起，毋厌于日，使志莫怒，使英华成
秀，使气得泄，若所爱在外，此夏气之应也，养生之道也。
秋三月，此谓容平。天气以急，地气以明，早卧早起，与鸡共兴，使志安宁，以缓秋刑。
收敛神气，使秋气平；毋外其志，使肺气精。此秋气之应也。养收之道也。
冬三月，此谓气闭藏。水冰地坼，毋扰于阳。早卧晚起，必待日光。使志若伏匿，若有
私意，若已有德，去寒就温，毋泄皮肤，便（使）气极。此冬气之应也。养藏之道也。
夫四时阴阳者，万物之根气也。所以圣人春夏养阳，秋冬养阴，以顺其根。故与万物沉
浮于生长之门。
《圣记经》云∶夫一日之道，朝饱暮饥；一月之道，不失盛衰；一岁之道，夏瘦冬肥；
百岁之道，节谷食米。千岁之道，独男无女。是谓长生久视。
《养生要集》云∶青牛道士云∶人不欲使乐，乐人不寿。但当莫强健为其气力所不任，
举重引强掘地，若作倦而不息，以致筋骨疲竭耳。然过于劳苦，远胜过于逸乐也。能从朝至
暮常有所为，使足不息乃快。但觉极当息，息复为，乃与导引无异也。夫流水不垢，户枢不
腐者，以其劳动之数故也。
又云∶《中经》曰∶人常欲数照镜，谓之存形。形与神相存，此照镜也。若务容色自爱
玩，不如勿照也。

《眼论》云∶夫欲治眼，不问轻重，悉不得涉风霜、雨水、寒热、虚损、大劳并及房室。
饮食禁忌悉不得犯。
《千金方》云∶凡少时不自将慎，年至四十即渐渐眼暗。若能依此将慎，可得白首。无
他，所以人年四十以去，恒须KT 目，非有要事不肯辄开，此之一术，护慎之极也。
又云∶生食五辛，接热食饮，刺头，出血过多。

《颜氏家训》云∶吾尝患齿动摇欲落，饮热食冷皆苦疼痛，见《抱朴子》云牢齿之法，
旦朝建齿三百下为良。行之数日，即便平愈。至今恒将之。此辈小术，无损于事，亦可修之。

《素问》说：春季的三个月，称为发陈（推陈出新），天地生机勃发，万物繁荣茂盛，应当晚睡早起，在庭院中阔步慢行，披散头发，放松形体，以使意志生发；顺应生机而不要杀戮，给予而不要剥夺，奖赏而不要惩罚，这是顺应春气的方法。也是养生的原则。
夏季的三个月，称为蕃秀（繁茂秀美），天地之气相交，万物开花结果，应当晚睡早起，不厌恶日光，使意志不愤怒，使英华秀发，使气机得以宣泄，好像所爱慕的事物在外一样，这是顺应夏气的方法，也是养生的原则。
秋季的三个月，称为容平（收敛平定）。天气急劲，地气清明，应当早睡早起，与鸡一同起床，使意志安宁，以缓和秋气的肃杀。收敛神气，使秋气平和；不要使志意外泄，使肺气精纯。这是顺应秋气的方法。是养收的原则。
冬季的三个月，称为闭藏。水结冰，地冻裂，不要扰动阳气。应当早睡晚起，一定要等到有阳光时再起。使意志如同潜伏隐匿，好像有私心秘密，好像已经接受了恩德，远离寒冷靠近温暖，不要使皮肤开泄，使气机极尽潜藏。这是顺应冬气的方法。是养藏的原则。
四时的阴阳变化，是万物的根本元气。所以圣人春夏养阳，秋冬养阴，以顺应其根本。因此能与万物一起沉浮于生长的大门之中。
《圣记经》说：一天的规律，早晨吃饱晚上饥饿；一个月的规律，不违背盛衰的变化；一年的规律，夏天瘦冬天肥；百岁的规律，节制谷物米饭的食用。千岁的规律，只有男子没有女子。这叫做长生久视。
《养生要集》说：青牛道士说：人不要让自己过于快乐，过于快乐的人寿命不长。只应当不要强健到被气力所不能胜任，举重、引强、掘地，如果疲倦了还不休息，导致筋骨疲竭罢了。然而过于劳苦，远远胜过过于安逸享乐。如果能从早到晚常有所作为，使脚不停歇才痛快。但觉得极度疲劳时就休息，休息后再做，这就与导引（一种呼吸吐纳和肢体运动相结合的养生方法）没有什么不同。流水不腐，户枢不蠹，是因为它们经常劳动的缘故。
又说：《中经》说：人常常想要多照镜子，这叫做存形（保持形体）。形体与精神相互依存，这就是照镜子的道理。如果致力于容貌自爱玩赏，不如不照镜子。
又说：大汗出时，急忙敷粉。穿着汗湿的衣服，使人容易得疮，大小便不利。
《养生志》说：发热时不要用冷水洗脸，如果洗脸不久就会变成痫病，或者起来就头晕目眩。
又说：足汗入水，使人发生骨痹病，凶险。
《千金方》说：人想要稍微劳累，但不要过度疲劳以及勉强做不能承受的事。
又说：凡是出大汗，不要马上脱衣服。喜欢因此得偏风（中风的一种，半身不遂），半身不遂。
又说：人出汗后不要在床上悬脚（将脚垂在床沿外），久了会成血痹，两脚沉重，腰痛。
又说：每到八月一日以后，就用微火暖脚，不要让下面受冷。（先生心意常想使气在下，不想让它泄于上。）
又说：冬天暖脚，夏天冻脚，春秋两季脚都冻着，这是普通人常法。
又说：不要把脚举向火。
又说：忍尿不便，膝盖冷成痹。忍大便不出，成气痔。
又说：久坐后站立小便，久立后坐下小便。
又说：人饥饿时，须坐着小便。如果饱食，站立小便。要小心。无病，可除虚损。
又说：小便时不要发怒，会使两脚及膝盖冷。
又说：大便时不要呼气，那是强行发怒。使人腰痛目涩，宜顺其自然而为之。
《眼论》说：想要治疗眼睛，不问轻重，都不得接触风霜、雨水、寒热、虚损、大劳以及房事。饮食禁忌都不得违反。
《千金方》说：凡是年轻时不自我谨慎，年届四十就渐渐眼花。如果能依照此法谨慎，可得白头到老。没有别的，所以人年过四十以后，必须爱护眼睛，非有要事不肯轻易睁开，这一条技术，是护慎的极致。
又说：生吃五辛（葱、蒜、韭、薤、兴渠五种辛辣蔬菜），接热食饮，刺头，出血过多。
极目远眺 夜间读细书 久处烟火环境 抄写多年 博弈不休 日落后读书 饮酒不止 热食面食 雕刻精细食物 哭泣流泪过度 房事无节制 夜晚远视星火 多次直视日月轮 月中读书 极目瞻视山川草木
以上十七件事（“辈”音反，意为类），都是导致失明的原因。养生之士，应该熟习并谨慎对待。
又说：有驰骋田猎，冒涉霜雪，迎风追兽，日夜不息的，也是伤目的媒介。
又说：凡是早晨起来不要用开水洗眼睛，会使眼睛干涩，失明，多泪。
又说：熊脂、猪脂两种油脂不做灯火，烟气进入眼睛，不能远视。
《养生要集》说：《中经》说：用冷水洗眼睛，引热气，使人眼睛早早失明。
《养性志》说：日月不要正对着怒目久视，使人早早失去光明。
《靳邵服石论》说：凡是洗头不要让头垢汁进入眼睛，使人眼睛早早失明。
《晋书》说：范宁字武子，患眼痛，向张湛求方。回答说用六物治疗：减读书一，减思虑二，专内视三，简外观四，早晚起床五，夜里早眠六。凡六物，用神火熬制，用气筛下，蕴藏在胸中七天。然后纳入方寸（心/脑）修养，不仅明目，也能延年。
《养生要集》说：《中经》说：头发，是血的穷尽之处。每天梳头一千次，头发不会变白。
《千金方》说：凡是早晨，想要吃完饭后，然后再洗梳。
《唐临香港脚论》说：多次需要用梳子梳理头发，每次梳头想要一百多次，梳头也能大去气滞。
《延寿赤书》说：《大极经》说：理发适宜朝向壬地（北方）。应当多次更换梳子，梳的地方多而不使疼痛。也可以让侍者梳。取多梳为佳。于是血流不滞，发根应当坚固。（让侍者洗手，然后让他梳。不然污染天宫也。）
又说：《真诰》说：梳头想要尽量多。通血气，散风湿。多次更换梳子更好。
又说：《丹景经》说：用手交替按摩头发反向梳理，只要热，使头发不变白。
《太素经》杨上善注说：牙齿是骨的余气，用杨枝等物资清洁牙齿，则牙齿鲜好。
《养生要集》说：《中经》说：牙齿，是骨的穷尽之处。早晚叩齿，牙齿不龋坏。
又说：吃完饭后应当漱口数次，否则使人牙齿龋坏（丘禹反。《说文》说：齿蠹也。）
又说：水银靠近牙齿，牙龈肿，喜欢掉牙。
《颜氏家训》说：我曾经患牙齿动摇欲落，喝热食冷都痛苦疼痛，见《抱朴子》说固齿的方法，早晨建齿三百下为良。实行几天，立刻平愈。至今常坚持这样做。这类小术，对事情无损，也可以修习。
《千金方》说：吃完饭后应当漱口数次，使人牙齿不败，口香。
《延寿赤书》说：郑都记说：夜行应当鸣天鼓，没有数量限制。辟百鬼邪。凡是鬼畏忌牙齿的声音，所以不敢侵犯人。（现在按：《大清经》说：天鼓指牙齿。）
《养生要集》说：《中经》说：指甲，是筋的穷尽之处。指甲不经常修剪，筋就不替换。
《千金方》说：凡是寅日剪手甲，午日剪足甲。（现在按：《唐临香港脚论》说：丑日手甲、寅日足甲割之。）
《养生要集》说：《中经》说：人不要经常沐浴，经常沐浴动血脉，引外气。
又说：饱食后立即洗头洗澡，会作头风病。

The *Suwen* (Basic Questions) states: The three months of spring are called "Fa Chen" (pushing out the old to bring forth the new). Heaven and earth generate together, and all things flourish. One should sleep late and rise early, take broad steps in the courtyard, let down the hair and relax the form, so as to allow the will to arise. Nourish life and do not kill; give and do not deprive; reward and do not punish. This is the response to the Qi of Spring. It is the way of nourishing life.
The three months of summer are called "Fan Xiu" (flourishing and beautiful). The Qi of heaven and earth intersects, and all things flower and bear fruit. One should sleep late and rise early, not be weary of the sun, keep the will from anger, allow the essence and brilliance to become秀 (elegant/showy), allow the Qi to be vented, as if what one loves is outside. This is the response to the Qi of Summer, and it is the way of nourishing life.
The three months of autumn are called "Rong Ping" (containing and leveling). The Qi of heaven becomes urgent, and the Qi of earth becomes clear. One should sleep early and rise early, rise with the chickens, keep the will peaceful and tranquil to缓 (slow down/mitigate) the punishment of Autumn. Collect and store the Shen (Spirit), make the Qi of Autumn peaceful; do not let the will go outward, making the Lung Qi refined. This is the response to the Qi of Autumn. It is the way of nourishing gathering (Shou).
The three months of winter are called "Bi Cang" (closing and storing). Water freezes and the ground cracks; do not disturb Yang. Sleep early and rise late, waiting for sunlight. Let the will be like hiding or lurking, as if having private intentions, as if already possessing virtue. Remove cold and seek warmth; do not let the skin pores open, allowing the Qi to reach its extreme depth. This is the response to the Qi of Winter. It is the way of nourishing storage (Cang).
The Yin and Yang of the four seasons are the root Qi of all things. Therefore, the sages nourish Yang in spring and summer, and nourish Yin in autumn and winter, to follow their roots. Thus, they float and sink with all things in the gate of growth.
The *Shengji Jing* (Sage Record Classic) states: The way of a day is full in the morning and hungry in the evening; the way of a month is not to lose track of waxing and waning; the way of a year is thin in summer and fat in winter; the way of a hundred years is to regulate grain and rice intake. The way of a thousand years is to have only men and no women. This is called long life and clear vision.
The *Yangsheng Yaoji* (Essential Collection for Nourishing Life) states: The Green Ox Daoist says: One should not desire excessive joy; those who are overly joyful do not live long. One should simply not exert oneself beyond what one's strength can bear, such as lifting heavy weights, pulling strong objects, or digging. If one continues working when tired, it leads to exhaustion of sinews and bones. However, excessive labor far exceeds the harm of excessive leisure and pleasure. If one can be active from morning till night, keeping the feet moving brings satisfaction. But when feeling extreme fatigue, rest; after resting, resume activity. This is no different from Daoyin (guiding and pulling exercises). Flowing water does not stagnate, and door hinges do not rot because of frequent movement.
It also states: The *Zhongjing* (Middle Classic) says: One should often look in the mirror, which is called "Cun Xing" (preserving the form). Form and Shen support each other; this is the meaning of looking in the mirror. If one focuses on admiring one's appearance, it is better not to look in the mirror at all.
It also states: When sweating profusely, apply powder immediately. Wearing sweat-soaked clothes causes sores and difficulty in urination and defecation.
The *Yangsheng Zhi* (Record of Nourishing Life) states: When fever comes, do not wash the face with water. If done, epilepsy may develop shortly, or dizziness upon rising.
It also states: If foot sweat enters water, it causes Gu Bi (Bone Bi syndrome), which is ominous.
The *Qianjin Fang* (Thousand Gold Prescriptions) states: One should desire slight labor, but avoid extreme fatigue and forcing oneself to do what cannot be endured.
It also states: Whenever there is profuse sweating, do not remove clothes immediately. This predisposes one to Pian Feng (Hemiplegia/Stroke), resulting in hemiplegia.
It also states: After sweating, do not hang feet off the bed edge. Over time, this leads to Xue Bi (Blood Bi syndrome), heavy legs, and lower back pain.
It also states: From the first day of August onwards, use mild fire to warm the feet; do not let them get cold. (The Master's intention is always to keep Qi below, not letting it escape upward.)
It also states: In winter, warm the feet; in summer, chill the feet; in spring and autumn, let the feet freeze. This is the common practice of ordinary people.
It also states: Do not raise feet towards fire.
It also states: Holding urine without urinating causes cold knees and Bi syndrome. Holding stool without defecating causes Qi Zhi (Qi Hemorrhoids).
It also states: Urinate while standing after sitting for a long time; urinate while sitting after standing for a long time.
It also states: When hungry, one must sit to urinate. When full, stand to urinate. Be careful. Without illness, this removes deficiency and damage.
It also states: Do not get angry while urinating; it causes coldness in both legs and knees.
It also states: Do not exhale forcefully during defecation, as that is forced anger. It causes lower back pain and dry eyes. It is best to let it happen naturally.
The *Yanlun* (Treatise on Eyes) states: To treat eye problems, regardless of severity, one must avoid wind, frost, rain, water, cold, heat, deficiency, severe labor, and sexual intercourse. Dietary taboos must not be violated.
The *Qianjin Fang* states: Those who are not careful in their youth will gradually experience dim vision by age forty. If one follows this caution, one can live to white hair. There is no other secret. Thus, after age forty, one must protect the eyes, not opening them unless necessary. This technique is the ultimate in protection and caution.
It also states: Eating raw five pungents (garlic, chives, leeks, scallions, and asafoetida), consuming hot food and drinks, pricking the head, and excessive bleeding.
Staring intensely into the distance, reading small print at night, staying long in smoky and fiery environments, copying texts for years, playing games without stopping, reading after sunset, drinking alcohol incessantly, eating hot wheat-based foods, carving fine foods, crying excessively, unregulated sexual activity, viewing stars and fireflies at night, frequently looking directly at the sun and moon, reading during the full moon, and gazing intently at mountains, rivers, trees, and grass.
These seventeen items (the character "bei" implies category/class) are all causes of blindness. Those engaged in nurturing life should study and be cautious about them.
It also states: Galloping hunting, braving frost and snow, chasing beasts against the wind, day and night without rest, are also mediums for injuring the eyes.
It also states: Do not wash the eyes with boiling water upon waking. It causes dry eyes, blindness, and excessive tearing.
It also states: Bear fat and pig fat should not be used for lamps. Smoke entering the eyes impairs distant vision.
The *Yangsheng Yaoji* states: The *Zhongjing* says: Washing eyes with cold water draws internal heat inward, causing premature blindness.
The *Yangxing Zhi* (Record of Cultivating Nature) states: Do not stare angrily at the sun and moon for long periods; it causes premature loss of sight.
The *Jin Shao Fu Shi Lun* (Treatise on Jin Shao Taking Minerals) states: When washing the head, do not let head dirt/grime enter the eyes; it causes premature blindness.
The *Book of Jin* states: Fan Ning, courtesy name Wu Zi, suffered from eye pain and sought a prescription from Zhang Zhan. Zhang replied with six methods: reduce reading one, reduce thinking two, focus on inner vision three, simplify external observation four, rise early and sleep late five, sleep early at night six. These six methods are "cooked" with divine fire, filtered by Qi, and stored in the chest for seven days. Then applied to the "square inch" (heart/mind). Not only does it brighten the eyes, but it also prolongs life.
The *Yangsheng Yaoji* states: The *Zhongjing* says: Hair is the culmination of Blood. Combing hair a thousand times prevents graying.
The *Qianjin Fang* states: In the morning, one should eat first, then wash and comb.
The *Tang Lin Hong Jiao Lun* (Treatise on Tang Lin's Gout) states: Frequently comb the head. Each time, comb over a hundred times. Combing greatly removes Qi stagnation.
The *Yanshou Chishu* (Red Book of Longevity) states: The *Daiji Jing* says: Hair combing should face the Ren direction (North). Change combs frequently; comb many places without causing pain. One may also have attendants comb it. More is better. Thus blood flow is not stagnant, and hair roots become firm. (Have attendants wash hands before combing. Otherwise, it pollutes the Heavenly Palace.)
It also states: The *Zhen Gao* says: Comb hair as much as possible. It promotes blood and Qi circulation and disperses wind-dampness. Changing combs frequently is superior.
It also states: The *Dan Jing* says: Massage hair alternately with hands and comb against the grain. Only heat is needed to prevent graying.
Yang Shangshan's commentary on the *Tai Su Jing* states: Teeth are the surplus of bones. Cleaning teeth with poplar twigs or similar materials keeps them fresh and good.
The *Yangsheng Yaoji* states: The *Zhongjing* says: Teeth are the culmination of bones. Clicking teeth morning and evening prevents decay.
It also states: After eating, rinse the mouth several times; otherwise, it causes dental caries. (The character "qu" refers to tooth decay. The *Shuowen* says: "Chi du ye" - worms in teeth.)
It also states: Mercury near teeth causes gum swelling and tooth loss.
The *Yan Shi Jia Xun* (Family Instructions of Master Yan) states: I once suffered from loose teeth wanting to fall out, and pain from hot and cold foods. Seeing in the *Baopuzi* that the method to firm teeth is to click them three hundred times in the morning. After practicing for a few days, it healed. I have persisted in this ever since. This minor art does no harm and can be cultivated.
The *Qianjin Fang* states: Rinse the mouth several times after eating to prevent teeth from decaying and keep breath fresh.
