In fact, the heart is closely related to the body, and a person's mental state can greatly affect the neurohumoral-endocrine and immune regulation system inside his body. This system determines whether it can maintain the harmonious relationship between various organs of the body, maintain the dynamic balance of the internal environment, and determine whether it can adapt to the constant changes of the external environment and effectively deal with various external stimuli and pathogenic factors. When pregnant women understand the relationship between health care and nourishing the heart, they should consciously "nourish the heart and benefit health care". Once the "heart care" and "health care" are adjusted, a lovely, lively and healthy baby with high emotional intelligence will be born.
