Heating principle of pregnant women's warm baby: Warm baby (warm baby patch) adopts the iron "oxidation and heat release" principle, uses microporous oxygen permeability technology, and adopts the way of completely isolating air, so that the heat dissipation of the product is balanced and lasting, and the heat can be generated by directly tearing off the outer package, and the temperature can be kept at about 5 1 -60 degrees 12 hours.
If pregnant women stick to the uterus, it is likely to cause uterine contraction, leading to fetal malformation and premature delivery. There are many kinds of "warm babies", with the heat preservation time ranging from 6- 16 hours, and the price is 10-25 yuan. The doctor said that this kind of fever product can be used as a temporary fever, but we should pay attention to the use method, and we must not directly contact the skin. In cold weather, we should wear more clothes to keep warm. Especially pregnant women should try to avoid using it. If used improperly, it will seriously affect the health of the fetus.
What should pregnant women pay attention to in winter?
1, keep warm properly.
Cold weather not only makes pregnant women feel uncomfortable, but also has adverse effects on the whole body system. It's best to go out less on a bitterly cold day. Pay attention to wearing more clothes when going out to prevent cold stimulation from causing cerebrovascular contraction. If you catch a cold, it will often lead to insufficient blood supply to the brain and increased secretion of phenolamine in the body. The increase of this substance will enter the fetus through the placenta, which may affect the growth and development of the fetus, cause fetal malformation, and make the fetus have congenital heart disease, anencephaly and cleft lip. Keep warm properly. In a room with heating or air conditioning, attention should be paid to reducing clothes to prevent overheating.
2. Pay attention to the ventilation of the room.
In winter, many families often seal doors and windows to prevent cold air from entering. Although this can effectively increase the indoor temperature, it often affects the indoor air, especially in some families that use coal balls for heating, families with small living areas or rooms with relatively concentrated population, and the air is difficult to be fresh. In this case, it is very important for eugenics to pay attention to frequent ventilation to prevent air pollution. Fetus is sensitive to air, and pregnant women inhaling too much polluted air will affect fetal health, which must be paid enough attention to. In winter, pregnant women should add clothes in time, keep indoor air circulation, pay attention to appropriate physical activities and improve their cold resistance and disease resistance.
3. Pay attention to scientific nutrition.
At present, vegetables are abundant in winter, but in some remote rural areas, pregnant women eat less vegetables and fruits, and some nutrients are reduced, so attention should be paid to proper collocation. In winter, pregnant women should pay attention to strengthening nutrition, diversifying their diet, avoiding partial eclipse, especially paying attention to eating more green leafy vegetables and fruits, supplementing folic acid and other nutrients needed by the fetus to prevent the fetus from getting sick due to nutritional problems.
4, pay attention to prevent colds.
Winter is the season of epidemic and high incidence of various viral infectious diseases. Because pregnant women have a special body and low disease resistance, they have certain susceptibility. Under normal circumstances, the more times pregnant women are infected with the virus in winter, the more serious the symptoms and the longer the course of the disease, the greater the adverse effects on the fetus and the higher the possibility of giving birth to deformed children. In addition, pregnant women's colds are often different from ordinary people, so we should pay special attention to taking medicine and use it as little as possible. When we have to take them, we should take them under the guidance of a doctor and don't abuse them.
5. Electric blankets should be banned.
When people use the electric blanket, because there is a capacitance between the human body and the electric blanket, even if the insulation resistance of the electric blanket is completely qualified, there will be induced voltage acting on the human body. The induced voltage between the human body and the electric blanket can reach 40-70 volts, with a current of 15 microamperes. This current is enough to generate electromagnetic waves that are harmful to the health of the fetus and pregnant women. 1984, American biologists investigated 1700 pregnant women who had miscarried because of using electric blankets. The results show that 75% of them have miscarried in the third month of winter, and it is in this season that people use electric blankets the most frequently, and the abortion rate of pregnant women is surprisingly high.
6. It is not advisable to take a hot bath.
In the first three months of pregnancy, pregnant women should not take a hot bath to prevent harm to the fetus. A large number of clinical data show that high temperature environment is easy to cause fetal anencephaly or cranial nerve defect. Taking a hot bath, if you don't pay attention to reproductive health care or have reproductive system diseases, may also cause intrauterine infection. Even in the middle and late pregnancy, it is not advisable to take a hot bath. Generally, a shower with the right temperature is enough. We know that the blood circulation of pregnant women is different from that of ordinary people. If they experience excessive stimulation of cold and hot water, the adjustment of their heart and brain load is often different from that of ordinary people, and they are prone to shock, dizziness or collapse due to blood circulation disorder, which may lead to unexpected dangers.
7. Sports
It is extremely necessary for expectant mothers to take physical exercise, which can not only enhance their physical fitness and reduce the occurrence of diseases, but also accumulate strength, which is conducive to the smooth delivery. When doing physical exercise during pregnancy, we should pay attention to the amount of exercise, and it is advisable to do light activities to avoid strenuous activities and fatigue. Expectant mothers should keep exercising in winter and don't stop because of the cold weather. But it's cold outside in winter, and it's easy to catch a cold, and sometimes the road is slippery and easy to fall, so pregnant women gymnastics is an exercise suitable for expectant mothers in winter.
8. Get more sunshine.
There is little sunshine in winter, so pregnant women should cherish it. During pregnancy, expectant mothers need more calcium than ordinary people to ensure the normal composition of fetal bone marrow formation. The absorption and utilization of calcium in the body can not be separated from vitamin D, which needs to be synthesized in the body with the participation of solar ultraviolet rays. Proper sun exposure for pregnant women is beneficial to the absorption and utilization of calcium. When the weather is good, you should go outdoors to bask in the sun. When it is windy, you should receive the sun indoors and sunbathe for at least half an hour every day. Pregnant women who live in a "north-facing house" usually have less exposure to the sun and need to go outdoors to bask in the sun.
9. Keep a good mood
Good and stable mood of pregnant women is one of the important factors to ensure prenatal and postnatal care. Scientific research has found that pregnant women remain optimistic, the fetus develops normally and the delivery is relatively smooth. However, if pregnant women are nervous, afraid, angry, irritable, sad and depressed, the concentration of harmful chemicals such as hormones in the mother will rise sharply, and the development of the fetus will be affected through the placenta. Foreign medical experts investigated the mothers of 500 fetuses with abnormal development, and found that 74% of them were often angry and angry during pregnancy. Especially in the early pregnancy, frequent anger, long-term or repeated tension can lead to abnormal development of fetal cleft lip, cleft palate and other organs, and in severe cases can lead to abortion, dystocia or stillbirth.
10, go to public places less.
Doctors say that low temperature, large temperature difference and low respiratory resistance in winter are prone to viral infectious diseases, such as rubella, cytomegalovirus, chickenpox, mumps and influenza virus in the first trimester, which will have an impact on fetal development and even lead to fetal malformation. Therefore, pregnant women should try not to go to shops, theaters and other public places to avoid catching flu and other diseases. If you are sick, you should use drugs reasonably under the guidance of a doctor, and you should not use drugs without authorization, so as not to cause harm to the fetus.
