The regulation of stress response in acupuncture treatment for insomnia is mainly achieved through the following mechanisms:

Regulate the function of the hypothalamic-pituitary-adrenal axis (HPA axis)

Reducing the secretion of stress hormones: Acupuncture can reduce the overactivity of the HPA axis and decrease the secretion of stress hormones such as cortisol in the body. When the human body is in a state of stress, the sympathetic nerve becomes excited, leading to an increase in the levels of stress hormones such as cortisol in the body, making it difficult for people to fall asleep or causing a decline in sleep quality. Through acupuncture regulation, this stress state can be alleviated, allowing the brain to enter a more relaxed state, which is conducive to falling asleep and maintaining deep sleep.

Regulate the balance of the autonomic nervous system

Balancing sympathetic and parasympathetic nerve activities: Acupuncture can activate the parasympathetic nervous system and curb excessive excitement of the sympathetic nervous system. The enhancement of the parasympathetic nervous system helps the body recover and repair, further improving sleep quality. When the excitation of the sympathetic nerve is inhibited and the function of the parasympathetic nerve is promoted, the body can relax better, creating favorable conditions for sleep.

Regulate the levels of neurotransmitters

Regulating serotonin (5-HT) : Serotonin is involved in mood regulation and the control of the sleep cycle. Acupuncture can increase the level of serotonin in the serum, thereby reducing anxiety and improving sleep.

Regulation of gamma-aminobutyric acid (GABA) : GABA is an inhibitory neurotransmitter that can help the brain relax and reduce the occurrence of anxiety and insomnia. Acupuncture can regulate the release of GABA, making it easier for the brain to enter a relaxed state and improving sleep.

Regulating norepinephrine: Acupuncture can reduce the level of serum norepinephrine, lower anxiety and stress responses, and help improve sleep.

Psychological adjustment effect

Alleviating negative emotions: Long-term mental stress, anxiety, depression and other negative emotions can lead to autonomic nerve dysfunction, which in turn causes insomnia. Acupuncture can regulate the emotional centers of the brain, such as the amygdala and hippocampus, to promote the release of neurotransmitters like endorphins in the brain. These substances have analgesic and anti-depressive effects, effectively alleviating negative emotions like anxiety and depression, making it easier for people to enter a relaxed state, and thereby improving sleep quality.
