After pregnancy, due to many special physiological changes in the body, such as sweat glands and sebaceous glands secretion, manifested as easy to sweat, sweat and head oil secretion increased, such as infrequent hair washing, bathing, skin and head dirt can affect the excretion function of the pores, easy to attract infection and itchy swelling or other skin diseases. Therefore, pregnant women should often wash their hair, bath, change clothes, keep themselves clean and hygienic to prevent infection and reduce skin diseases. Frequent hair washing can also keep the hair soft, shiny, beautiful and comfortable, which is conducive to the physical and mental health of pregnant women. However, the following matters should be noted when bathing: 1, the bath time should not be too long bath, the bathroom due to poor ventilation, air turbidity, humidity, will reduce the oxygen content of the air, coupled with the stimulation of hot water, will make the body’s blood vessels expand, so that the blood flow into the human trunk, limbs more, while the blood into the brain and placenta should be relatively temporarily reduced, the oxygen content is also bound to reduce, and the human Brain cells have a very low tolerance for oxygen deprivation, which can cause fainting in the shower. If a pregnant woman takes a bath for too long, in addition to the above situation, it will also cause the fetus to lack of oxygen. If the fetal brain hypoxia time is very short, generally will not cause any adverse consequences, if the time is too long, it will affect the growth and development of the nervous system. Therefore, experts suggest that pregnant women should not generally take a bath for more than 15 minutes, or to the degree that the pregnant woman itself does not appear dizzy, chest tightness. 2, pregnant women should not sit in the bath Women’s bath is unfavorable, the bath should not sit in the bath during pregnancy, especially in late pregnancy is absolutely prohibited to sit in the bath, in order to prevent premature birth. This is because: under normal circumstances, the female vagina to maintain a certain degree of acidity, in order to prevent the reproduction of germs. This physiological phenomenon is closely related to the secretion of estrogen and progesterone by the ovaries. When a woman is pregnant, especially in the second trimester, the placental villi produce large amounts of estrogen and progesterone, and the amount of progesterone produced is greater than that of estrogen. Therefore, at this stage, the shedding of vaginal epithelial cells is greater than the proliferation, which decreases the amount of lactic acid in the vagina and thus the killing power of foreign germs. If you take a sitz bath, the dirty water after the bath may enter the vagina, and the vagina’s disease prevention power is weakened, which will easily cause cervicitis and adnexitis, and even intrauterine or vulvar infections that may cause premature birth. Therefore, pregnant women should not sit in the bath, and do not go to the public bath to take a bath. 3, the water temperature should not be too high According to relevant expert research, pregnant women bathing water temperature is too high will affect the fetal brain development. Of course, hot water so that the body temperature of pregnant women than the normal body temperature rose 1.5 degrees, the fetal brain cell development is likely to stagnate, when up to 3 degrees, the fetal brain cells are at risk of being killed. Therefore, the bathing water temperature of pregnant women should not be too high. 4, be careful of slippery ground pregnant women due to physical inconvenience, and the bathroom floor will generally be more words, so pregnant women should be particularly careful to prevent falls. Another point is that pregnant women should not take the plane after 32 weeks of pregnancy cycle may occur premature birth and amniotic fluid rupture early delivery.
