The ways in which acupuncture affects the endocrine system of patients with insomnia mainly include the following aspects:

Regulating the hypothalamic-pituitary-adrenal axis: Acupuncture can regulate the function of the hypothalamic-pituitary-adrenal axis by stimulating specific acupoints, thereby balancing hormone levels in the body. This helps to reduce the secretion of stress hormones such as cortisol, relieve anxiety and stress, and thereby improve insomnia symptoms.

Regulating the secretion of neurotransmitters: Acupuncture can influence the secretion of neurotransmitters, such as serotonin and norepinephrine. These neurotransmitters play a significant role in regulating emotions, sleep and other aspects. By regulating the secretion of these neurotransmitters, acupuncture can improve the sleep quality of patients with insomnia.

Promoting normal hormone secretion: Acupuncture can stimulate the endocrine system of the human body and promote the normal secretion of hormones. For instance, acupuncture can regulate thyroid function and keep it in a balanced state, thereby preventing insomnia caused by abnormal thyroid function.

Improving autonomic nerve function: Acupuncture restores balance to the overly excited sympathetic nerve by regulating autonomic nerve function. This helps lower physiological indicators such as heart rate and blood pressure, allowing patients to enter a relaxed state and thus fall asleep more easily.
