On December 7 or 8 each year, when the sun goes through 255 degrees, it is one of the "snowfalls" of the 24th solar season. Heavy snow, as its name suggests, has a large amount of snow. The ancients said: "The big ones, Sheng Yeh, and thus Xuesheng also." At this time, the snow is often under large, wide range, hence the name snow.
At this time, the minimum temperature in most parts of China has dropped to 0°C or below. Often in the area where the cold and warm air fronts the strong cold air, heavy snow and even Blizzard will fall. It can be seen that the heavy snowfall indicates the beginning time and the amount of snowfall in the heavy snowfall period. This is the same as the snowfall, rain, and valley rain. It is a direct reflection of precipitation's solar terms.
The weather started to get colder this season. Heavy winds and heavy snow will often appear, and the temperature will drop suddenly. People with respiratory diseases such as colds, tracheitis and bronchitis will be several times more than normal. Therefore, we must pay more attention to protect our health.
Cold protection: protect the head and feet
Snowy seasons, we should pay attention to the invasion of wind evil and cold evil, especially the head and feet. This is because the occurrence of some diseases has a lot to do with not paying attention to keeping warm. According to traditional Chinese medicine, the three parts of the body's head, chest, and feet are most vulnerable to cold pathogens.
According to the theory of traditional Chinese medicine, the head is "the meeting of Zhu Yang". For those who do not wear caps, the amount of heat that is lost from the head when the ambient temperature is 15°C accounts for 30% of the total body heat; if the temperature is 4°C, the total amount of heat lost from the head is 60%. Cold weather can cause blood vessels to contract, and people can experience headaches and dizziness. For cerebrovascular patients, cold can easily induce cerebrovascular disease. This shows that the head warmth is very important.
In winter, the cold has invaded the human body, and the chest and abdomen are the first to bear. After the chest and the abdomen catch cold, it is easy to break the yang in the body and trigger a heart attack. In addition, the cold can also induce the occurrence of gastrointestinal diseases, so the warmth of the chest and abdomen can not be ignored.
As the saying goes, "Cold from the feet," the foot is farthest from the heart, the blood supply is slow and little, the subcutaneous fat layer is thin, and the warmth is poor. Once cold, it will reflexively cause capillary contractions of the respiratory mucosa, making the disease resistant. The drop in force leads to upper respiratory tract infection. Therefore, the heavy snowfall should pay attention to the warmth of the foot.
The cold snowfall, first of all, should be appropriately increased or decreased according to changes in the climate: wearing hats, matching collars, wearing double warm shoes is the best choice for cold protection. Second, patients suffering from cardiovascular and cerebrovascular diseases, arthritis, and digestive system diseases should pay more attention to protecting themselves against cold and warmth, and wear thicker coats when they go out. When you are unwell, you should take the initiative to go to the hospital for an examination.
After the heavy snowfall, some women feel cold because of the cold weather. Modern medical research believes that because of the menstrual period, pregnancy and puerperium or suffering from anemia, gastro-intestinal disease and chronic illness, the body's resistance is reduced, the cold resistance is poor, so the winter is particularly cold. On the other hand, if women lack nutrition, suffer from hypotension or hypothyroidism, they may also cause local or systemic blood circulation disorders, especially peripheral blood vessel and blood circulation disorders, which can cause cold hands and feet.
Diet: eat more fruits and vegetables
Heavy snowfall, dry indoor climate, and reduced fresh vegetables can cause vitamin B deficiency and induce angular cheilitis. Therefore, you should drink more water and eat more fruits and vegetables in winter.
In this climate, people can supplement their dietary habits. When eating tonic, eat more garlic, leek, pepper, ginger, coriander, onion, yam, longan, chestnut, and apricot, etc., as warm food to help protect the cold. However, due to dry weather coupled with improper diet, it is easy to get angry and suffer from aphthous, but also pay attention to control the number. At the same time, pay attention to eat less meat, eat more vegetables and warm fruit, should drink more porridge.
Due to indoor and outdoor drying, the air humidity is very low, we must drink plenty of water, timely replenishment of water, ensure the normal metabolism of organs, the general daily water supply should not be less than 2000 to 3000 ml (ie often say "8 cups of water", a cup About 300 ml).
Living: early morning and good morning
Snowy solar terms, we must pay attention to maintaining the stability and peace of mind, living and exercise are regular.
The winter days are short and long nights. It is necessary to pay attention to the early lying and lateness, not to stay up late, and not to get up early to do morning exercises.
Emotions: Emotional anti-ophthalmopathy
In addition, we must pay attention to peace, and many diseases are caused by emotions. For example, because of emotional instability and irregular living habits, it is easy to cause glaucoma, a type of blinding eye disease. The disease usually occurs in the cold months of winter. The symptoms are: eye pain, eye swelling, vision loss, accompanied by headache, nausea and other symptoms. . Therefore, we must always maintain a stable mood, to avoid mental stress and excessive excitement; pay attention to regular living, do not stay long in the dark, to prevent increased pupil pressure caused by the expansion of the eye; sunny weather, moderate participation in outdoor activities, because it can increase the fundus The supply of oxygen in the blood vessels reduces the accumulation of carbon dioxide in the blood and avoids the increase in intraocular pressure. In cold weather and in inclement weather, it is necessary to minimize out-going to reduce the impact on the eyes.
In addition, if the snow is large, the snow does not turn, people stay in the snow for a long time and very likely to suffer from "snow blindness", that is, "snow ophthalmia." The main reason for the formation of the disease is that the ultraviolet rays in the sunlight reflect from the snow to the cornea of ​​the human eye, causing corneal injury. The symptoms are: photophobia, tearing, foreign body sensation, itching, tingling, edema, and therefore snow. The duration of stay should not be too long, such as working in the snow or traveling and sightseeing should wear sunglasses with UV protection.
