Who all want to give birth to their children healthy, but many young couples in preparation for making people, some bad habits still continue, in the long run, the baby is extremely unfavorable, the following is ready to get pregnant before you should not do things, the future of the prospective father, the prospective mothers to pay attention to. Expectant mothers can not commit the silly things a: with wearing contact lenses Pregnant women cornea water content is higher than normal, if you wear contact lenses, easy because of the lack of oxygen leads to corneal edema, which triggered corneal inflammation, ulcers, and even eventually lead to blindness. At the same time, the corneal curvature of a pregnant woman will also change with the pregnancy cycle and her physical condition, which will increase or decrease the degree of myopia. If you are reluctant to wear contact lenses, it is easy to cause significant damage to the neovascularization of the eye due to discomfort, and even lead to corneal epithelial peeling. In addition, once the contact lenses are unclean, it is very easy to harbor bacteria, resulting in corneal inflammation, ulcers, and even blindness. Expectant mothers can not commit the silly thing two: eat tender hot pot According to the relevant departments of the examination and determination, the infection rate of toxoplasma gondii in the flock is 61.4%. The larvae of Toxoplasma gondii are often hidden in the infected lamb cells, and the short-term heating when eating hot pot can not kill the parasitic Toxoplasma gondii larvae within the cells of the meat, and after eating the larvae can be in the intestinal tract, through the intestinal wall with the blood diffusion to the whole body, and through the placenta infected with the fetus, the serious cases can be aborted, stillbirths, or affect the development of the fetus’s brain, and the development of the microcephaly, macrosomia (hydrocephalus), or anencephaly and other malformations. Expectant mothers can not commit the silly thing 3: hot bath High heat can cause fetal nerve cell death, so that the number of brain nerve cells to reduce the brain nerve cell death can not be regenerated, can only rely on some glial cells to replace. These glial cells lack the physiological functions of nerve cells, thus affecting intelligence and other brain functions, making the child’s intelligence low and poor reflexes. Expectant mothers can not commit the silly thing four: a large number of calcium and cod liver oil Long-term consumption of large quantities of cod liver oil and calcium food, will cause loss of appetite, itchy skin, hair loss, sensory allergies, protruding eyeballs and so on. At the same time, too high a concentration of calcium in the blood will cause muscle weakness, vomiting and cardiac arrhythmia, etc., all of which are not beneficial to the growth of the fetus. Some fetuses are born with teeth already erupted. In addition to the precociousness of the infant, another possibility is due to the fact that during pregnancy, the pregnant woman takes a lot of vitamin A and calcium preparations or calcium-containing foodstuffs, so that the dental follicles of the fetus are prematurely calcified in the uterus and erupted. If needed for medical treatment, they should be taken as prescribed by the doctor. Expectant mothers can not make silly things 5: stay up late Normal life and work will help the whole body organs and systems of the equilibrium state, and then provide a stable environment for the growth of the fetus. Regularly staying up late will affect the physiological and psychological health of the pregnant woman herself and is not conducive to the growth of the fetus. In addition, as the uterus grows larger during pregnancy, it gradually presses on the inferior vena cava, causing poor venous return in the lower body, which can easily lead to varicose veins and hemorrhoids in the lower limbs and perineum. Regularly staying up late and reducing the amount of time spent lying down (preferably on the left side) will make the above symptoms worse. The mother-to-be can’t do anything stupid: rubbing acne ointment. Acne ointment has the following four common ingredients: azelaic acid, antibiotics, benzene peroxide and vitamin A acid. Azelaic acid and antibiotics in the U.S. Food and Drug Administration (FDA) pregnancy classification is classified as level B, which means that animal testing can not show that there is a risk, but there is no sufficient research report on human testing, it should be evaluated in the physician’s assessment of the efficacy and risk before being used with caution. Benzene peroxide and vitamin A acids are classified as level C, which means that they have been shown to be teratogenic in animal studies, but there are no adequate studies in human trials, so they should be avoided in pregnancy. Expectant mothers can not commit the silly things seven: sleeping windows closed After people fall asleep, if the windows and doors are closed, without 3 hours, the indoor carbon dioxide will increase more than 3 times, bacteria, dust and other harmful substances will also be doubled. Therefore, sleep should leave some window slits, in order to let the outdoor fresh air into the indoor carbon dioxide discharge in a timely manner. Expectant mothers can not make silly things eight: hair coloring perm Nowadays, women have long said goodbye to more than a decade ago, once pregnant, the image of a pudgy face, who want to be a beautiful mother. Despite being pregnant, you still dress well and behave elegantly. But can you still pursue fashion without fear as before? The answer is no. Not only when you are pregnant, but also during the first three months of pregnancy, you should stay away from hair products such as mousse, hairspray and hair dye. This is because the chemicals in these products can hinder the development of the fetus’s bones and even lead to deformities in fetal development. But there is no need to be frustrated, love beautiful moms-to-be can still change a refreshingly simple, easy to take care of hairstyle, I believe that the same will not be inferior. Expectant mothers can not commit the silly things nine: wearing high heels 1, a slip of the foot into a thousand years. Fall is one of the dangers of wearing high heels, women during pregnancy, due to changes in body physiology, body awkward, walking inconvenience. The heels of high-heeled shoes are generally more than 4 centimeters, so that the pregnant woman’s body center of gravity elevated, so that it is easy to fall, resulting in ankle sprains or miscarriage, preterm delivery. 2, aggravate the burden of posture distortion. Pregnant women in order to the whole body balance and stability, forcing the waist spine of the excessive convex curvature, the formation of pregnant women’s unique head up chest protruding belly posture, which gives the waist and back muscles increased burden, resulting in low back pain during pregnancy. If you wear high heels, it will be more aggravated by the distortion of this posture. At the same time wearing high heels will appear in front of the leg bow, after the leg taut, easy to cause lumbar back muscle strain, because the weight of the whole body is concentrated in the forefoot easy to cause toe joint pain disease. 3, harm the fetus in the abdomen. For middle and late pregnant women, may also cause the abdominal cavity before and after the shortening of the diameter distance, so that the pelvis tilt increased, artificially induced fetal head position difficult labor. At the same time, the pressure on the abdomen will rise, causing the blood vessels to be subjected to greater pressure, thus restricting the entire blood circulation and affecting the blood supply to the fetus, which will result in insufficient supply of nutrients to the fetus and affect its development. Therefore, during pregnancy, women should choose soft flat shoes that fit well, or slope-heeled shoes with a heel height of no more than 3.3 centimeters, which is conducive to the health of the mother and the fetus.
