It's getting cooler and cooler in the morning recently, and the pace of autumn is getting faster and faster. After autumn and summer, it's time for Bailu. What's the date of Bailu in 2018? What's the climate feature of Bailu solar term? Let's have a look.
When is the time of Bailu
Bailu time in 2018: 00:29:37 on September 8, 2018, and 29:00 on July (University) 2018 in the lunar calendar.
1. Bailu is the 15th solar term in the 24 solar terms, and it is also the end of the Shenyue and the beginning of the youyue in the dry and branch calendar; the time point is from September 7 to 9 in the Gregorian calendar every year, when the sun reaches 165 degrees in the Yellow longitude.
2. Bailu is one of the 24 solar terms in the lunar calendar. When the sun reaches 165 degrees of the Yellow longitude, Bailu solar terms are handed in. Bailu is the third solar term of autumn, indicating the end of the season of mengqiu and the beginning of the season of mid autumn. Dew is a drop of water formed by condensation of water vapor on the ground or near earth objects due to the decrease of temperature. Therefore, Bailu is actually a sign that the weather has turned cold.
3, the White Dew season, bronchial asthma incidence rate is very high, so we should do a good job of prevention. The focus of this solar term is to strengthen physical exercise, pay attention not to catch cold sooner or later, and actively prevent allergic diseases.
4. The occurrence of nasal diseases, asthma and bronchopathy should be prevented in Bailu season. In particular, the patients who suffer from the above-mentioned diseases due to physical allergies should be more careful in their diet regulation. They should eat less or no fish and shrimp, stewed pickles with raw and cold heat, and spicy, sour, salty and sweet food.
5. After the plants began to leak into the White Dew solar term, the summer wind was gradually replaced by the winter wind, the cold air turned to attack, and the warm air gradually retreated. When cold air moves southward in batches, it often brings a certain range of cooling range. People like to use the proverb "White Dew, autumn wind night, cool night" to describe the situation that the temperature drops faster.
What are the solar terms of Bailu
1. It is said in the interpretation of the seventy-two months of the moon: "the August Festival & hellip; hellip; is getting more and more cloudy, and the dew is coagulating and white. 'as the weather turns cold, there will be many dewdrops on the ground and leaves in the early morning. This is because the water vapor condenses on it at night, so it's called Bailu. The ancients used four seasons to match five elements. Autumn belongs to gold and is golden and white. Therefore, autumn dew is described as white. When you enter "Bailu", you will feel a little cool at night.
2. On August 15, the gate of wild geese opened, and the geese came with frost on their heads. Frost is caused by the invasion of cold air. The daily average temperature is above 0 ℃, and the surface temperature suddenly drops below 0 ℃. The water between the crop cells freezes, and constantly absorbs the water inside the cells, forming cell dehydration, which leads to the disaster of crop withering or death. Sometimes, although there is no white frost on the surface of plants, crops are still suffering from frost damage due to the ground temperature below 0 ℃. It is also a type of frost.
3. It's a classic way to keep healthy. Of course, autumn freezing is not suitable for everyone. For example, if the local blood supply of diabetic patients is poor, if the blood vessels are stimulated by cold air all at once, it is easy to have vasospasm, further reduce the blood flow, and easily cause tissue necrosis and diabetic foot. In addition, diabetes and cardiovascular and cerebrovascular diseases are often accompanied. Cold air stimulation is more likely to induce cardiovascular and cerebrovascular diseases, and even lead to myocardial infarction and other consequences. Therefore, it's better for diabetics not to get cold in autumn. In addition, people with weak constitution, such as the elderly and children, patients with cardiovascular and cerebrovascular diseases, chronic bronchitis, asthma and arthritis are not suitable for autumn freezing.
4. If the temperature difference between morning and evening is large, clothes and quilts should be added in time, otherwise, it is very easy to get a cold, and the patients with chronic diseases such as bronchitis, asthma, peptic ulcer are also easy to induce or aggravate the disease. The epidermis of navel is the thinnest, there is no fat tissue under the skin, but there are abundant nerve endings and plexus, which are sensitive to external stimulation. If the protection is improper, sleep at night to expose the abdomen or beauty to wear the navel, cold air is very easy to enter the human body through the navel.
