Pregnancy preparation seems simple, but there are many things that can't be done. Men and women are forbidden to do sauna during pregnancy, because sauna will make people stay in high temperature environment for a long time, especially after men are exposed to high temperature, it will affect the ability of spermatogenesis in the body, make sperm activity worse and reduce the quality. After such sperm develops into fertilized eggs, the health of the fetus cannot be guaranteed.
Both men and women can't use whitening cosmetics when they are pregnant, because many whitening and freckle-removing cosmetics used by women now contain heavy metal lead, which will affect the internal environment after entering women's bodies. If pregnant at this time, it will also affect the health of the fetus, so that the fetus will suffer from various diseases after birth, mental retardation or ischemic anemia, and inattention and other uncomfortable symptoms. Therefore, women cannot use this kind of cosmetics when they are pregnant.
Exposure to radioactive substances is also something that men and women cannot do during pregnancy. Computers and mobile phones still have some radiation, but the damage to the fertility of men and women is relatively small. There are some large instruments containing radioactive substances, and men and women must stay away from them, because those radioactive substances will cause serious harm to men and women. If they are exposed to radioactive substances during pregnancy, it will increase the rate of fetal malformation and increase the risk of pregnancy.
Men and women can't smoke and drink for a long time during pregnancy, because smoking and drinking will make the body absorb harmful substances and affect pregnancy and fetal development, while staying up late for a long time will make the human body qualitatively worse, can't guarantee the quality of sperm and eggs, affect normal pregnancy and can't improve a healthy environment for fetal development. Women can't lose weight during pregnancy, because losing weight will lead to dieting, affect the body's intake of various nutrients, and easily lead to female malnutrition. Under such conditions, pregnancy can not guarantee the health of the fetus, and the risk of miscarriage after pregnancy is particularly high.
