Dog days introduction:
The dog days, which appear between the light summer heat and the summer heat, are the periods with the highest temperature, humidity and sultry heat in a year. Three volts can be divided into initial, intermediate and final volts, and its date is determined by the coordination of the 24 solar terms and the dates of the trunk and branch dates. After "entering the volt", many places in the country will enter the continuous high temperature mode.
The traditional almanac stipulates that the number of volts will be counted on the third Geng of the summer solstice, which means that counting backwards from the summer solstice and counting to the third Geng day will begin to fall. The Geng Day here refers to the day with the prefix Geng in the ancient Ganzhi Ji Ri Law. Fu means that yin qi is forced to hide underground by yang qi; It also means that the weather is too hot to move.
The length of the dog days mainly lies in the difference between the middle and the lower days. Because the time of the third Geng day after the summer solstice solar terms is different every year, the number of days that lead to midsection is also different. The mid-lying time is long or short, which may be 10 day or 20 days.
Dong Sanjiu introduced:
Winter March 9 refers to the third nine days after the winter solstice, and the time is probably around the middle and late days of 1 month. People will call it the coldest period in winter. Why do people think it's coldest in winter? In fact, it is based on the amount of heat absorbed and emitted by the ground, because the days are short in winter, the ground absorbs less solar radiation heat, and the ground emits more heat.
Only after March 9th in winter did the air temperature near the ground begin to rise gradually, so it was the coldest time of the year around March 9th after the winter solstice. Three or nine days in winter is the lowest temperature in a year, so we should pay attention to keep warm and avoid diseases such as colds and fever.
Winter March 9th is also a high season for chronic bronchitis, asthma, allergic rhinitis and other diseases, but it is also a good time to treat these diseases. Therefore, in the winter March 9th period, it is necessary to strengthen physical fitness, exercise more and avoid sedentary. The benefits of physical exercise can strengthen the digestion ability of the stomach, stimulate metabolism, improve physical conditions and enhance resistance.
