How long are the dog days in summer on the solstice?

The dog days in 2022 will last for 40 days, from July 16 to August 24, 2022. Generally speaking, the start and end are 10 days, and the middle is 10 and 20 days, so the dog days are 30 and 40 days. People also call the 40-day dog days the extended dog days. It is very hot in dog days, but there are also abnormal weather. If there is more rain in dog days, the weather will become cool. People can predict the weather in the next three days by the weather in Wangfu. The axe king also refers to the first day in the palace. If the weather in Axe King is very hot, it will usually be very hot for the next three days. The summer solstice is usually in late June every year. Its arrival means summer, and the first day of stay means summer. I believe many people have heard the old saying that the summer solstice and sunset are on the third Geng, and the third Geng is the first day of autumn, which comes from the summer solstice. The dog days are usually between the hot summer and the hot summer, and they are usually humid and sultry. When it falls in, the surface will absorb too much heat, but the heat can't be released in time, and there will be a constant accumulation of heat on the surface, and the temperature will change and get hotter and hotter. There is usually more rain in summer, which usually increases the humidity in the air. The heat capacity of dry air is less than that of water. Before the thunderstorm, the average wind speed was much smaller and the air pressure became lower, which was also the reason why the weather became sultry. At the end of the day, the weather will get cold, but every region is different. After falling asleep, people will be more or less affected, and there will be loss of appetite and irritability, which needs to be adjusted through diet. In summer, people will sweat a lot, leading to the loss of salt in the body. Therefore, it is necessary to replenish water and salt in time. You can drink more tea to get rid of the fire. Even in hot summer, people need to keep exercising, and they can choose to jog in the morning or at night. In the hot sun, people should avoid traveling in high temperature, and take good protection even when they go out.
