Hormones, called hormones in English, are chemical substances that are produced in the human body by endocrine cells. Hormones in the human body can regulate the metabolic activities of various tissues and cells and influence the physiological activities of human beings. It is a necessary substance for normal physiological activities of the human body, and once deficient, it will cause many diseases. Hormones do not directly participate in the conversion of substances and energy in human body, but indirectly control the whole metabolic process, such as growth and development are the original metabolic process of human body, but if hormones participate in this process will speed up, if hormones decrease, growth will be slow, so hormones have a strong regulatory effect on human reproduction, growth, development, and various physiological functions. Many diseases in the human body are caused by hormone imbalance, such as menopause symptoms, which are caused by a large reduction of estrogen and physical discomfort, manifested as irritability, anxiety, insomnia, night sweats, etc.
