What time do pinworms usually come out at night?

Between 9:00 and 11:00 pm is the working time of the Sanjiao meridian. The chest, upper abdomen and lower abdomen are called Sanjiao in traditional Chinese medicine. Pinworms mainly live in the digestive tract of the human body. Pinworms will come out to lay eggs at night, usually around 9-11:00. When the Sanjiao meridian is working, pinworms are most active.
