People think that before and after the vernal equinox, due to climatic reasons, the body function is unbalanced, that is, it needs to pay attention to the harmony of yin and yang, so it is not suitable for sharing a room, but due to the lack of scientific basis, modern people do not pay attention to this point.
The origin of this statement
Sting is the time when thunder shakes, and then the vernal equinox is also the time when small animals come out to move. If it rains more, the thunder will not stop at once. The ancients thought that men and women should not share the same room at this time, because thunder would have a negative impact on couples. Therefore, "Qi Yaomin's Miscellaneous Notes on Books" says: On the vernal equinox, Lei Naisheng, reserve five days first and go to bed outside. Sun Shi's Note: Those who don't give up will make children unprepared. It means that couples have to sleep in separate rooms these days, and for five days before and after, they have made taboos and it is unhealthy to have children. In fact, these records reflect the ancestors' awe of nature. At that time, medicine was not as advanced as it is today, and most of it came from the unknown. Now we all know that the vernal equinox has no special influence on future children.

The essence is that the four seasons health care should follow the laws of solar terms and the change of heaven and earth. The annual deficit includes the solstice in winter and the solstice in summer. The monthly deficit refers to the days before the first quarter of the month, the last few days of the second quarter of the month and the days when the moon is not seen. The deficiency of the sun is the date of the solar eclipse or the lunar eclipse, which means that there should be no sexual intercourse on such a day.
