Every year on November 23 or 24, it will be regarded as light snow when the sun reaches 240 ° longitude. The weather gradually became colder during this period, and the average initial snow period in the middle and lower reaches of the Yellow River was basically consistent with the light snow season. Although it starts to snow, it is generally small and it freezes at night. If the cold air is more powerful and the warm and humid airflow is more active, it may also snow. For example, from November 15th to 20th, 1993, a part of the winter wheat area in the north fell to a blizzard. Around light snow, agricultural production in most areas of China began to enter winter management and farmland water conservancy infrastructure.
As the yang in the sky rises, and the yin in the ground drops, the heavens and the earth are closed, and the yin and yang are not intersected, so everything loses its vitality, and the heavens and earth are closed and turned into the cold winter.
The size of the snow is also classified according to the amount of precipitation. Snow can be divided into three types: light snow, medium snow, and heavy snow. The 24-hour precipitation is less than 2.5, the medium snow is 2.6 to 5.0, and the heavy snow is more than 5.0. The few hours of precipitation is less than 1.0, the medium snow is 1.1 to 3.0, and the heavy snow is greater than 3.0.
Xuexue (mostly on November 22, sometimes 23rd on the monthly calendar): Xiaoxue indicates the start time and degree of snowfall. Snow is the product of cold weather. Light snow, solar terms, the northern part of the southern region began to enter winter. The end of the lotus has no rain cover, and the chrysanthemum still has frost branches. Because there are Qinling and Dabashan barriers in the north to block the invasion of cold air, the rigor of the cold wave has been reduced, resulting in the warm winter in South China. The number of snowfall days in the whole year is less than 5 days, which is much less than the middle and lower reaches of the Yangtze River at the same latitude. Before the heavy snowfall, there were very few chances of snowfall. Even in the winter season, it is rare to see the charming scenery of thousands of trees and pears bloom. Because the temperature of the near-surface layer in South China often stays above 0 ℃ in winter, snow cover is more difficult than snowfall. Occasionally, although I saw the sky succumbing, I did not see the broken Qiongranyu on the ground. However, in the cold northwestern plateau, snow generally begins in October all year round. The number of snowfall days in the northwest of the plateau can reach more than 60 days throughout the year, and some alpine regions may have snowfall throughout the year.
Snow is the second half of November in the solar calendar and the second half of October in the lunar calendar. Snow is a season that reflects weather phenomena. The ancient book Qunfang Spectrum said: Snow will be cold and the snow will be cold, and the ground will not be too cold. That is to say, due to the cold weather, the form of precipitation changes from rain to snow due to the cold weather, but this At that time, the amount of snow was not large due to the not too cold, so it was called light snow. With the advent of winter, the climate is getting colder. Not only the dew on the ground becomes frost, but also the rain in the sky becomes snowflakes. After snowing, the earth is covered with white plain clothes. However, since the weather is not too cold at this time, the snow below is often half-ice or half-melted, or it immediately melts after falling to the ground. Meteorologically it is called wet snow; sometimes it is rainy and snowy. Drops are called sleet; there are also white ice particles that are as large as rice grains and are called rice snow. This solar term precipitation is still scarce, and it is far from meeting the needs of winter wheat. The morning mist is a little more than the previous solar term.
At this time, the north of the Yellow River has reached the north wind and the snow is blowing, and at this time, the first snow will appear in the northern part of our country. Although the amount of snow is limited, it still reminds us that it is the season to keep warm. Before and after Xiaoxues solar terms, the weather is often cold and dark, and peoples mood will be affected at this time, especially those with depression are more likely to aggravate the illness, so in this solar term, friends will be on a day with little light Here you must learn to nurse yourself.
In addition, modern medical research has found that seasonal changes have a direct impact on patients with depression, because of the neurotransmitters associated with depression, the serotonin system in the brain is closely related to seasonal changes. In the spring and summer, the serotonin system has the strongest functions, and the autumn and winter seasons are the weakest. The decrease in sunlight time on that day causes a lack of serotonin in the brain of depression patients, followed by a series of symptoms such as insomnia, irritability, pessimism, and misery.
Xiaoxue season, the sky has accumulated overcast, the cold is not deep and the snow is not heavy, hence the name Xiaoxue. At this time, there will be initial snow in the north of the Yellow River. Although the amount of snow is limited, it still adds some humidity to the dry winter. Humidity of the air will improve respiratory diseases. However, there will be cooling weather after snow, so it is necessary to keep warm to prevent colds.
In Xiaoxues solar terms, the weather is often cold and dark. At this time, peoples mood will also be affected by it, which is particularly likely to cause depression. Medical research in recent years has found that depression is the most common psychological disorder in humans. Authorities estimate that if mild depression is included, the prevalence of depression worldwide is about 11%. In our country, there is no precise statistics on depression, but in fact depression can appear around people anytime, anywhere, but people have not faced this psychological first illness. Experts said that many doctors or patients family members did not know enough about the performance of depression, so that many patients were not detected in time and received the correct treatment. Depression can cause a decline in work, study and living ability, seriously affect the recovery of chronic physical diseases, increase the economic burden on society and families, and even lead to an increase in suicide rates in society.
Depression is a kind of emotional disorder, which is characterized by long-term depression of the patient and a state of depression. As for the symptoms of depression, it can be expressed in the following four levels:
认识 3. Cognitive and ideological aspects: pessimism, gray will, incompetence, hopelessness and helplessness, self-blame, thoughts of suicide, thoughts of slow thinking, guilt and self-punishment, and even more serious delusions;
行为 4. Behavioural aspects: speak less and have a low tone, slow speed, less movement and slowness, and severe stagnation, but sometimes irritable behavior, alcoholism, and even suicidal behavior.
Due to insufficient understanding of this disease in modern medicine, some minor symptoms of depression, such as fatigue, insomnia, gastrointestinal upset, persistent headache and back pain, are often misunderstood as other diseases. As a result, correct treatment cannot be obtained.
From the perspective of traditional Chinese medicine etiology, there are no more than three causes of the disease: internal causes (injury, sadness, fear, horror, shock, seven emotions, excessive stress), external causes (wind, cold, hot, dry, hot, hot, and six sex injuries), non-internal External causes (atrioventricular, plague, flutter injury, poisoning, etc.). The occurrence of depression is mostly caused by internal emotions, which are seven emotions. The seven emotions include changes in seven emotions: joy, anger, worry, thought, sadness, fear, and shock. People often have seven emotion changes in their daily life. This change is a different reflection of objective external things. It is a normal mental activity and a normal physiological phenomenon of the human body. Generally, it does not cause disease. Only under sudden, strong or long-lasting emotional stimuli, will it affect the normal physiology of the human body, cause disorders of viscera and blood functions, and lead to the occurrence of diseases. Lung, fear of kidney injury. It shows that a persons mental state reflects and reflects a persons mental and psychological activities, and the health of mental and psychological activities directly affects the occurrence and development of mental illness, and can be said to be the key to mental illness. Therefore, Chinese medicine believes that mental activity is closely related to depression, and it is not unreasonable to attribute the cause of depression to the seven emotions, so recuperating and maintaining health is especially important for friends who have depression.
Su asked. Ancient Innocence said: Evil and thief-like winds, sometimes avoid it; Tranquility and nothingness, true energy from it, inner spirit, never disease? And Su asked. The theory of anger and the sky states: Quietness means that the meat is closed and refused. The ancients stated from the inside and outside that they must conform to the changes in nature and avoid the attack of evil spirits to the outside; they must be cautious and quiet inside. That is, the mind is pure, the emotions are unobstructed, and the essence and spirit are kept inside without losing, and the physiological state of the body and spirit unity is maintained.
In addition, modern medical research has found that seasonal changes have a direct impact on patients with depression, because the 5-hydroxytryptamine system in the brain is closely related to seasonal changes in the neurotransmitters associated with depression. In the spring and summer, the serotonin system has the strongest function, and the autumn and winter seasons are the weakest. The decrease in sunlight time on that day causes a lack of serotonin in the brain of depression patients, followed by insomnia, irritability, pessimism, and misery.
Overall the viewpoints of Chinese and Western medicine, in order to avoid the disadvantageous factors brought to friends with depression in winter, we should pay attention to mental conditioning in this solar term. Depression patients should actively adjust their mentality, maintain optimism, and control anger, often participate in some outdoor activities to enhance physical fitness, sun exposure to maintain the stability of 5-hydroxytryptamine in the brain, listen to music to make the wonderful melody for You add joy to your life.
In addition, patients with depression should also strengthen diet. In terms of diet, eat more high-calorie foods, such as mutton, beef, milk, and fish, and drink some tea, coffee and other beverages appropriately. Patients who still cannot improve their symptoms by adjusting their diet can choose nimodipine, Duxe, thyroxine and other drugs for treatment.
