The deterioration of our living environment in recent years has led to a sharp increase in the incidence of tumors, infertility and other diseases in humans, and we need to pay special attention to all kinds of pollution if we want to have a healthy baby. The pollution of the environment is not something we can do with our own personal efforts, but the various types of pollution in our daily lives are commonplace but often overlooked. For example, various air purifiers, bathroom deodorizers, various scented volatile substances, dishwashers, detergents, etc., various decorative materials, hair dyes, various dyes, cosmetics, and especially the unsuitable ones, all cause damage to our bodies to varying degrees. Especially for mothers-to-be who are preparing to give birth or are already pregnant, it is important to pay extra attention to the possible damage that these harmful factors can cause to the embryo and the fetus. Because early embryos are sensitive to all kinds of damage, and the first three months of pregnancy are a critical period for the development of several fetal organ systems, even prolonged exposure to poisons in the late stages of pregnancy may lead to abnormal development of the fetus. In addition, food contamination is a very important cause of disease. Minimizing eating out and consuming less anti-seasonal fruits and vegetables are important measures to reduce the incidence of disease from the mouth. In conclusion, pollution is pervasive. For your own sake and for the sake of having a healthy child, do your best to pay attention to the pollution in your life.
