Improve autonomic nervous system function

Negative ions also have the function of regulating the autonomic nervous system. The autonomic nervous system spontaneously controls the gastrointestinal tract, heart, blood vessels and other internal organs. Negative ions can improve the function of the autonomic nervous system and activate the endocrine glands and hematopoietic function that are closely related to the autonomic nervous system. When the autonomic nervous system is stable, insomnia, constipation and anxiety will disappear, and the human body will come alive. All these activation reactions are the source of vitality and the source of the body's natural self-healing ability.
