The effect of Baihui acupuncture on insomnia is mainly reflected in the following aspects:

Regulate the functions of the nervous system

The Baihui acupoint is located at the intersection of the midline of the top of the head and the line connecting the tips of both ears. It is an important acupoint on the Governor Vessel and is closely connected to the brain. Acupuncture at the Baihui point can regulate the function of the nervous system, promote physical relaxation, and alleviate insomnia symptoms caused by neurasthenia, anxiety, etc. By stimulating the Baihui point, the excitation and inhibition processes of the cerebral cortex can be regulated, allowing the brain to enter a more relaxed state, which is conducive to falling asleep and maintaining deep sleep.

Improve the circulation of qi and blood in the brain

The Baihui acupoint has the functions of raising Yang, lifting the sunken area, refreshing the mind and calming the spirit. Acupuncture at the Baihui point can regulate the circulation of qi and blood in the brain, ensuring it receives sufficient blood supply and thereby improving insomnia caused by insufficient qi and blood in the brain. At the same time, acupuncture on the Baihui point can also promote blood circulation in the head, relieve tension in the head, and further improve sleep quality.

Regulate the secretion of neurotransmitters in the brain

Acupuncture at the Baihui point can regulate the secretion of various neurotransmitters in the brain, such as serotonin and gamma-aminobutyric acid (GABA). Serotonin is involved in mood regulation and the control of sleep cycles. Acupuncture at Baihui point can increase the level of serotonin in the serum, thereby reducing anxiety and improving sleep. GABA is an inhibitory neurotransmitter that can help the brain relax and reduce the occurrence of anxiety and insomnia. Acupuncture at the Baihui point can regulate the release of GABA, making it easier for the brain to enter a relaxed state.
