What should pregnant women pay attention to in winter? How should pregnant women keep warm in winter?

The weather in winter is getting colder and colder, and everyone feels the harm brought by cold air. Some special people need more protection. Pregnant women are a very special group. In winter, pregnant women need to pay attention to many things, especially warm work, because this is a basic guarantee for pregnant women.

1, what should pregnant women pay attention to in winter

As a mother-to-be, it is best to use these overheated warm-keeping products less in winter. Many pregnant mothers know that they should be less exposed to cold substances during pregnancy to avoid the impact of cold on the fetus. But in fact, during pregnancy, both too cold and too hot substances will affect the health of the fetus. What else will affect the development of the fetus? Do you know all this? Bian Xiao told you.

1, some pregnant mothers are afraid that their babies will get cold in winter, so they will warm their babies.

(1) What pregnant mothers don't know is that if the warm baby is improperly used, the adhesion part is facing the uterus, which is very easy to cause uterine contraction and affect the health of the fetus.

(2) The fetus is extremely sensitive to high temperature in the first trimester, and high temperature may even cause fetal malformation or abortion. In the third trimester, high temperature is easy to kill fetal brain cells and affect fetal intelligence. The environment in which the fetus grows is the pregnant mother's body, and the mother's body temperature is generally kept at around 37℃, which is more suitable for the growth and development of the fetus.

(3) If a pregnant mother uses a warm baby during pregnancy, the maternal temperature will overheat, changing the environment for the fetus.

(4) Someone tested the warm baby and found that the warm baby can reach about 60℃ or even higher, while the temperature of the general hot water bottle is also set at about 75℃. High temperature environment is easy to cause uterine contraction, leading to fetal abortion. In addition, the environment of fetal reproduction changes, which directly affects fetal development and leads to malformation.

Therefore, pregnant mothers should be careful to keep warm in winter. It is best not to use warm baby, hot water bottle and other overheated warm-keeping products, so as not to affect the health of the fetus. In addition, it should be noted that pregnant mothers should not bathe with overheated water during pregnancy, and it is best to use warm water. Some pregnant mothers prefer to soak their feet in winter. Although soaking feet is good for the body, it should be noted that pregnant mothers had better not soak feet when the fetus is not particularly stable in the first trimester. Soaking feet can relax muscles and promote blood circulation, which is easy to cause abortion or bleeding.

2. Pregnant women should be less exposed to radiation-sensitive warm-keeping products in winter.

(1) Studies show that long-term exposure to electromagnetic radiation will lead to many diseases, including dizziness, memory loss, tinnitus, etc., which will damage the immune system and increase the probability of cancer, while the fetus is more sensitive to electromagnetic radiation.

(2) Every winter, electric blankets become an ideal heating product for every family, but for expectant mothers during pregnancy, electric blankets can easily become the invisible killer of the fetus.

(3) Most electric blankets are made of cloth and resistance wires. Although the current is small, because the electric blanket is close to the pregnant mother, electromagnetic waves will directly act on the mother, and the fetus is highly sensitive to electromagnetic waves, which is enough to endanger the health of the fetus. Especially in the first trimester, the fetus before 6 weeks is most sensitive to electromagnetic radiation, and low-dose radiation may cause fetal malformation; Embryos of 0-3 months may cause limb defects or deformities, which may lead to abortion; 4-5 months is the formation period of fetus, and it is also the differentiation and development period of fetal brain cells. Long-term radiation is easy to cause gene mutation in fetal brain, leading to intellectual damage and even dementia; 6- 10 months is the growth period of the fetus. The main consequences will lead to low physical function, poor constitution and resistance after birth, and even damage to the central nervous system, leading to mental retardation of the baby.

When using the electric blanket, pregnant mothers should try to turn on the preheating in advance and turn off the electric blanket when sleeping. In addition, small sun, electric heating pad, hand warmer, hand warmer, etc. They are all warm-keeping products that will produce radiation, so pregnant mothers should be cautious when using them in winter.

3. The correct way for pregnant mothers to keep warm in winter.

(1) Keep the room warm and increase or decrease clothes appropriately.

Pregnant mothers need to add clothes properly in winter, especially those who live in the south where the temperature is changeable in winter. Because the metabolism of pregnant mothers is very strong during pregnancy, pregnant mothers should pay attention to the permeability and sweat absorption of clothes when choosing clothes in winter, and it is best to choose some pure cotton clothes. If heating is turned on indoors in winter, families should pay attention to keep indoor ventilation and open the window for air in time. In addition, because the heating is on all day and the air is relatively dry, a humidifier can be used to maintain good indoor humidity. Try not to turn off the heating at home when you go out, and turn it to a low temperature, because it is cold outside. At home, the pregnant mother's spirit is more relaxed. If the indoor temperature is also relatively low, it is easier to catch cold, so it is best to keep it around 2 1 degree indoors.

(2) Insist on proper exercise and go out for a walk.

A friend of my mother said: In winter, I will choose to walk and sing at home, and walk indoors every day, especially after dinner, to warm my body and increase my resistance through proper exercise.

It is the healthiest way to keep warm in winter for pregnant mothers to increase their body's heat energy through proper exercise. You can do some light exercise such as maternal exercise indoors, or go for a walk outdoors when the weather is better, and take more walks to breathe fresh air. But pregnant mothers should pay attention to safety when exercising or going out. In addition, pay attention to keep warm when going out to prevent colds. When the weather is particularly cold, wear a hat to prevent the head from radiating too fast, and choose a warm scarf to protect your neck.

(3) Pay attention to diet and supplement nutrition.

During pregnancy, pregnant mothers have higher body temperature because their metabolism is faster than ordinary people, but there are still more expectant mothers who are particularly afraid of cold and are prone to cold hands and feet. This kind of pregnant mother belongs to yang deficiency and cold constitution, so she should eat more warm food, directly warm her body through food, and appropriately supplement warm food such as beef and mutton, chicken, eel, hairtail, jujube, chestnut, leek and garlic sprout. Eat less cold food, such as frozen pears, frozen persimmons and ice cream. If the pregnant mother often has dry nose and mouth, flushed face, fever in hands and feet, Huang Chi in urine and dry stool in winter, then the pregnant mother belongs to the constitution of yin deficiency and heat excess, and can eat more foods that nourish yin and clear heat, such as sea cucumber, turtle, duck meat, rabbit meat, tremella, black fungus, tofu, water chestnut, lily, shepherd's purse and spinach.

Does B-ultrasound have a negative impact on fetal health? Now people will be more worried about this problem. Under what circumstances should I do B-ultrasound?

(1) According to the principle of B-ultrasound, it is conducted by ultrasonic waves, which is harmless. Without electromagnetic and ionizing radiation, this sound wave has no harm to human tissues. But if the wavelength of sound is concentrated in a fixed place, it will produce thermal effect. When this influence reaches a certain level, human tissues may have adverse effects, and substances in cells, including chromosomes, will be affected. Theoretically, high-intensity ultrasound can strengthen the function of tissue through high temperature and cause damage to tissue.

(2) In fact, 94 MW/cm3 low-intensity B-ultrasound is used in medicine, which will not harm the fetus. So far, there is no report about fetal malformation caused by B-ultrasound. At present, the B-ultrasound examination used in obstetric hospitals is safe for the fetus.

(3) Whether the embryo survives can be determined as intrauterine pregnancy or ectopic pregnancy; When there is blood flow or abdominal pain in the private parts of pregnant women, in order to determine whether the embryo is intrauterine pregnancy or ectopic pregnancy in time; Or to determine whether the fetus has stopped growing or threatened abortion, this situation needs to be identified by B-ultrasound. In addition, there is no need to do B-ultrasound for routine examination. In the fifth week of intrauterine pregnancy, fetal heartbeat can be seen by B-ultrasound. 3 ~ 8 weeks is the sensitive period of intrauterine organ differentiation, so unnecessary external stimulation should be reduced. B-ultrasound can identify whether the fetus has congenital heart disease, neural tube malformation, limb loss, congenital cleft lip and palate and other gross malformations in the middle stage.

(4) The time of B-ultrasound examination is suitable at 22-26 weeks of pregnancy, because about 20 weeks is the period of rapid development of fetal brain. If B-ultrasound is done too early, the fetal development is still very small, some tissues can't be seen clearly, and the purpose of screening abnormalities can't be achieved, which affects the fetal brain development.

(5) In the 32nd week of the third trimester, in order to understand the intrauterine development of the fetus, we can do a B-ultrasound to understand the intrauterine development, amniotic fluid volume, umbilical cord and fetal size, and give correct guidance for further pregnancy. To identify the fetus, we can do a B-ultrasound at the 37th week of pregnancy, and find out the problems existing in the developing fetus in time, such as placenta, umbilical cord and fetus. In order to prepare for delivery.

(6) Some abnormal conditions during pregnancy require B-ultrasound. For example, if a woman has bleeding in her private parts during pregnancy, the doctor should distinguish between placenta previa and low placenta; B-ultrasound is needed to determine whether pregnant women have the threat of premature delivery; And the slow development of the fetus in the uterus, to find the reason; Because of premature water breakthrough, fetal heart changes and unclear fetal position, it may increase the number of B-ultrasound during pregnancy, which is really helpless for doctors.

2. How do pregnant women keep warm in winter?

1, don't let the heating hurt your health.

The most troublesome thing about central heating is that it cannot adjust the temperature independently. People's physique is different, and the requirements for temperature are also very different. Some people like to be cool, while others prefer a state in which the body can sweat slightly.

In fact, lower temperature is more beneficial to health. Studies have proved that people in tropical areas live shorter lives, while people in cold areas live longer lives. It is more appropriate to control the indoor temperature at 23-26 degrees Celsius in winter, and try to approach the lower limit. So it is suggested that every family can buy a thermometer to control the indoor temperature.

In addition, in winter, many people close their windows at home, afraid of cold air coming in, releasing hot air and lowering the indoor temperature. The central heating temperature cannot be adjusted independently, and the indoor air circulation is not smooth, which will also reduce the human body's resistance. It is recommended to ventilate the room every day to ensure the fresh indoor air. The best ventilation time is between 10 in the morning and 3-4 pm. The air pollution is serious in the morning, so it is not recommended to open the window. Observe whether there is smoke when ventilation. If the visibility is low, don't open the window first to avoid polluting the indoor environment.

For good ventilation, it is recommended to install windows that can open the upper edge when decorating. In this way, when opening the window, cold air can be prevented from blowing directly on people, thus reducing colds and preventing rain and snow from entering the house. If there are many rooms at home, they can be ventilated one by one, which can ensure the overall temperature of the rooms. Finally, it should be reminded that the ventilation effect of houses with transparent north and south is better, and the ventilation effect of high-rise buildings is worse, so the ventilation time should be relatively extended.

2. Pregnant women and children should use less electric blankets.

Electric blanket has high electromagnetic radiation, so pregnant women and children should use it with caution. Electric blanket is not suitable for laying on soft mattress, otherwise the heating wire will be easily broken and leaked. Electric blankets are suitable for opening before going to bed, and must be turned off when sleeping. If children have the habit of wetting the bed or the elderly can't take care of themselves, it's best not to use it.

It is best to use marble to floor.

Floor heating is a heating method that has been used for thousands of years. 1930, the United States began to promote the use of floor heating. At present, many new residential areas in China have begun to adopt floor heating.

Floor heating can effectively solve the problems of high local temperature and poor soaking effect of traditional radiators, and avoid large temperature difference changes in the same room. Compared with the air convection caused by indoor air conditioning, the air convection in the floor heating room is smaller, which will not cause dust flying and dust accumulation caused by air convection, and effectively protect the respiratory organs. At the same time, the head temperature is the highest and the foot temperature is the lowest. In floor heating, the ground temperature is high, the ceiling temperature is low, and the indoor space temperature distribution conforms to the suitable temperature for people.

However, if the new house is laid with floor heating, we must pay attention to indoor pollution in the first two years. This is because two kinds of materials are used for floor heating. One is composite flooring, such as reinforced composite wood or solid wood composite, which has good stability and low probability of thermal expansion and contraction, but contains harmful substances such as formaldehyde, especially new flooring. Solid wood flooring is not suitable for laying geothermal energy because of its high moisture content and easy deformation when heated. In terms of installation technology, the keel should be laid when the solid wood floor is laid, and there is air in the middle of the keel, which will reduce the thermal efficiency. Secondly, tiles, floor tiles and other stone materials have very good heat dissipation effect, so it is recommended to use them in the living room to achieve the best efficiency. However, in the continuous baking of stone, radioactive substances may be released, causing indoor pollution.

Therefore, in the first two years after moving in, families with floor heating must have more ventilation and choose qualified and regular brands of wood or stone. Using less red granite and more marble can reduce the adverse effects of radioactive pollutants on health.

Don't turn off the heating when you are not at home.

In order to save energy more effectively, many residential areas have adopted self-heating systems. During the interview, many people said that this kind of heating is very convenient. You can turn it on if you want, and turn it off if you want.

But it is this kind of random switch that will increase energy consumption and is not good for your health. If the indoor heating is stopped all day, the room will be completely cooled. Increasing the overall temperature will consume far more energy than a room with a basic temperature. Moreover, people stay in cold rooms for a long time, unable to keep warm, and easily catch a cold. Therefore, it is suggested that self-heating residents can use low-temperature heating when they go out during the day, and raise the temperature in time after returning home, so that the room will be very comfortable. If you are not at home for a long time, you can turn off the heating.

In order to make self-heating play its greatest role, ordinary people should learn to decorate their rooms reasonably. Generally, the bedroom is suitable to be arranged in the position of Chaoyang. Try not to be close to the stairwell, elevator room and other places with more cold walls to avoid excessive heat consumption.

In addition, the heat loss in winter is relatively large, so it is also important to keep warm. Now many families have been renovated twice, and many people will transform exposed parts such as balconies to expand the area of bedrooms or living rooms. Most exposed balconies have no insulation walls, and even if they are incorporated indoors, they will still emit more heat. For such a family, it is suggested to add a sliding door between the balcony, living room or bedroom, which can play the role of heat preservation and sound insulation in cold winter.
