The summer heat is the season when the summer heat ends. "Out" means hiding and ending. As the name implies, the heat indicates that the heat is coming to an end. The Twelve Episodes of the Moon Order says: "In mid-July, this place will stop, and the summer heat will stop here." At this time, the dog days have passed or will soon end, so it is called "the summer ends here". There are also proverbs all over the country, indicating that the summer heat is fading away. However, the weather in autumn is not really cool. At this time, the sunny afternoon is no less hot than midsummer, which is in line with the saying that "autumn tigers are as poisonous as tigers". This also reminds people that there will still be hot weather in autumn, which can be regarded as a return of summer. Gu Tieqing, the author of Jia Qinglu, described the summer heat: "After the summer heat, the weather is still cloudy, and it takes about 18 days to cool down;" As the saying goes, eighteen pots of summer heat means eighteen days of bathing. "This means about eighteen days of sweating. At this time, the longitude of the sun is 150 degrees, and the almanac records: "Fighting refers to the summer heat, and the summer heat will retreat, crouching and diving, hence the name. "

From the agricultural point of view, there is also the autumn harvest scene of "summer valley yellow" and "busy rice fields". In addition, after the summer, continuous autumn rains often patronize us. Farmers should pay special attention to the weather forecast, seize every sunny day, and do a good job in autumn harvest without losing time.

The solar terms in summer are in the alternate period from hot to cool, and the yang in nature tends to converge from venting, and the rise and fall of yin and yang in human body also changes accordingly. At this time, the daily routine should be adjusted accordingly. In autumn, the first thing to adjust is sleep time. Going to bed early and getting up early is what people expect. However, few people know the importance of sleep health care by physicians and health care experts in past dynasties. In fact, scientific health care needs a comprehensive grasp of the laws and methods of sleep.

The sleep theory of traditional Chinese medicine is based on the materialism of unity of form and spirit, which holds that sleep and insomnia are the functional state of unity of yin and yang of human body and a normal physiological phenomenon, including several aspects:

First, the rise and fall of yin and yang day and night determines the degree of drowsiness of the human body. Due to the movement of celestial bodies, nature is in the ups and downs of yin and yang, which is characterized by the alternation of day and night, with yang during the day and yin at night. Moreover, the yin and yang of the human body also changes with the growth and decline, so there is an alternation of strangulation and lethargy. Yang is dominant and Yin is dominant. It can be said that since the emergence of human beings, there has been a law of human activities-work at sunrise and rest at sunset. "Lingshu Nutrition Health Club" said: "When the sun enters the sun, the yin is exhausted, and at midnight, the meeting is held, and everyone is lying down, and life is called yin; Ping Dan's yin is exhausted and Yang is angry. If there is no self-nature, it is the same as heaven and earth. " "Zero Pivot and Mouth Questions" further explains this as follows: "At midnight, when the yang is exhausted and the yin is full, the eyes are dull"; During the day, "Yin Qi is tired, Yang Qifeng is embarrassed";

Second, the physiological basis of sleep is the operation of camp and health; The change of people's sleepiness is based on the operation of ying qi (that is, qi that moves in the pulse) and Wei qi (that is, qi that moves outside the pulse and has defensive function), among which Wei qi is the most relevant. "Ling Shu Wei moves qi" says: "In the body, it is fifty-one days and one night, and it is twenty-five weeks in Yang and twenty-five weeks in Yin". "Lingshu Nutrition Health Club" also has the same statement: "It goes at 25 degrees Yin and 25 degrees Yang, and it is divided into day and night, so qi starts from Yang and ends at Yin". "Get up" here means getting up and falling asleep. It can be seen that when Wei Qi moves in yin, Yang Qi is exhausted and Yin Qi is abundant, so the body is quiet and sleepy (the human body enters a relatively static state and wants to sleep); Walking in the sun, the yin is full and the yang is full, so the body moves and wakes up (the human body enters the dynamic and wakes up). Therefore, the sleep and wakefulness of the human body are commanded by the heart. When the heart is calm, it will be sleepy, and when the heart is moved, it will be awkward. Too many emotions make it difficult to sleep.

Modern medical research divides sleep into four stages: ① falling asleep, ② shallow sleep, ③ moderate deep sleep and ④ deep sleep. When entering the first and second stages, it is in a hazy state and easy to be awakened, while the third and fourth stages are in a deep sleep state. Generally speaking, it is not easy to wake up when you are asleep.

The reason why autumn health care emphasizes ensuring sleep time is because sleep has a good health care function. The medical book "Ten Questions" unearthed in Mawangdui said: "It is not a matter for a husband to lie down and give birth to a people. For example, people who live on food, such as birds, geese, frost (storks), snake sandalwood (eels), fish and turtles, squirming people, and people who live on food (necessary). Therefore, a past (night) without lying down will not last for a hundred days. It can be seen that not only people need sleep, but also any living thing can't do without it. In other words, without normal sleep, normal life activities cannot be well maintained.

The role of sleep includes five aspects:

First, eliminate fatigue.

In sleep, the human spirit is preserved in the five internal organs. When the five internal organs are comfortable, qi and blood will be harmonious, body temperature, blood pressure and heart rate will be relatively reduced, and breathing and endocrine will be significantly reduced, thus reducing metabolic rate and restoring physical strength.

Second, protect the brain.

The oxygen consumption of the brain is greatly reduced during sleep. Adequate sleep is conducive to the storage of energy in brain cells, which helps to restore energy and improve brain efficiency.

Third, enhance immunity.

Sleep is not only a re-creation process of intelligence and physical strength, but also an important means of disease rehabilitation. Sleep can produce more antigens and antibodies and enhance the body's resistance, so modern medicine often regards sleep as a treatment for intractable pain and mental illness;

Fourth, promote development.

Sleep is closely related to children's growth and development, and children's growth rate increases rapidly during sleep, so ensuring adequate sleep time is one of the conditions for children's height growth;

Fifth, it is conducive to beauty.

Sleep has a great influence on skin fitness. This is because during sleep, the process of skin surface secretion and clearance is strengthened, capillary circulation is increased, and skin regeneration is accelerated, so that facial haggard and skin fine lines caused by overwork are recovered during sleep. So sleep is also the basic guarantee of beautiful skin.

Here, I would like to remind my elderly friends in particular that with the growth of age, the elderly will have the phenomenon of deficiency of qi and blood, poor sleep during the day and poor sleep at night. Ancient health experts said: "Lack of sleep is a big problem for the elderly", and Ancient and Modern Yan Jia thought that the elderly should "sleep when sleepy", which is in line with the viewpoint of health preservation. In addition, the ancients also emphasized the importance of meridian sleep in sleep health (that is, falling asleep at noon and noon every day), thinking that yin and yang meet at noon, which is extremely declining and unbalanced in the body, and it is necessary to lie still and wait for the weather to recover. Modern research has found that from 0 pm to 4 pm, the functions of various organs in the body drop to the lowest point; At noon 12 to 13, it is the most tired time for human sympathetic nerves. Statistics show that sleeping at noon for the elderly can reduce the incidence of cardiovascular and cerebrovascular diseases. Therefore, meridian sleep not only has the significance of disease prevention and health care, but also conforms to the principle of health preservation.

If you can enter the fourth stage of sleep normally, your brain will get a good rest and ensure the best mental state the next day. This is what we hope, and it is also one of the important ways of fitness in autumn.
