Why moxibustion on the back is far more important than moxibustion on the abdomen?

Hello, moxibustion is one of the traditional Chinese medicine external adjustment methods, which has a good effect of invigorating qi and tonifying yang. The back belongs to the yang side in human body, and moxibustion on the back has a good effect of tonifying yang. It is 5-7 o'clock in the evening, the sun has set, and the yang of the human body must enter the yin blood, so that people can fall asleep normally. If moxibustion is done at night, it may lead to yang failing to enter the yin, leading to insomnia. But not everyone will suffer from insomnia when doing moxibustion at night, and it varies from person to person. Some people with very poor yang will sleep well when doing moxibustion at night. I hope it will help you!
