Insomnia can be treated with a stellate ganglion block. Insomnia is actually a state of nerve excitation in the brain, which leads to the patient not entering the state of sleep. Currently there are relevant studies confirming that insomnia can be treated by stellate ganglion block. Stellate ganglion block is to inhibit the stellate ganglion nodes, so that the excited nerve cell tissues become less active. Because the brain’s nerve tissue is very sensitive and complex, when a stellate ganglion block is used, the excited nerve tissue is controlled and the symptoms of insomnia are resolved. The stellate ganglion block has a direct modulating effect on the autonomic nervous system and reduces autonomic nervous system excitation during local nerve anesthesia. Patients with insomnia often experience autonomic over-excitation, which affects the quality of sleep. Stellate ganglion block therapy can improve insomnia. Therefore when a patient chooses stellate ganglion block for insomnia, it needs to be performed by a medical professional.
