The implication and symbol of dog days

The arrival of the dog days implies and symbolizes that the weather has entered the period with the highest temperature, the highest humidity and the hottest heat in a year.

Three volts is a general term for initial, middle and final volts. The dog days appear between the heat and the heat. The word "V" in three volts has two meanings. One is that yin is forced to hide underground by yang. Second, it means the weather is too hot to move. Sleep time is determined by the coordination of solar terms and dry branch dates. The dog days are characterized by high temperature, low pressure, high humidity and low wind speed.

According to the traditional calculation method in China, the third Geng day from summer to the future is the beginning of "initial lodging", the fourth Geng day is the beginning of "intermediate lodging", and the first Geng day after beginning of autumn is the beginning of "final lodging". Because every Geng day is 10 days apart, the stipulated time of the first day and the last day is 10 days. The number of days in midsummer is long or short, which may be 10 or 20 days, depending on the date of the third Geng Day (the first autumn) after the solar term of summer solstice every year.

Matters needing attention in dog days

The dog days are the hottest time of the year. In this hot weather, we should try our best to reduce outdoor activities. Even if you want to go out, you should do a good job of sun protection and heatstroke prevention to avoid sunburn or heatstroke.

2. Blow less air conditioning

When the weather is hot, many people like to stay in air-conditioned rooms all day. In fact, this is not good, and it is not good for people to blow air conditioners for a long time. Therefore, it is necessary to control the time of blowing air conditioners in dog days.

Step 3 use a parasol

Avoid the scorching sun when traveling. You can wear a sun hat, sunglasses and an umbrella. Try to walk in a cool place and apply sunscreen when going out.

Step 4 wear loose clothes

Wear loose clothes when going out, don't wear chemical fiber clothes, because rabbits can't sweat and dissipate heat in time, wear cotton, hemp and silk clothes that should absorb sweat.
