Does smog have a big impact on pregnant women? How do expectant mothers cope with smog weather?

Does smog have a big impact on pregnant women? 1. The pollutants that pregnant women breathe will reach the uterus through the umbilical cord.

2. The air pollution before the birth of the fetus will lead to the low IQ of the child.

3. Smoking can lead to low birth weight, premature delivery and stillbirth.

4. If the expectant mother lives in an environment with high concentration of ozone or carbon monoxide, the baby is prone to cleft lip and palate and heart valve defects, which is three times higher than other babies.

What are the hazards of smog to pregnant women?

First: respiratory tract injury

Smog particles can be inhaled directly, which is most likely to damage respiratory function and can cause pneumonia, asthma, pharyngitis, rhinitis, ophthalmia and so on. When the pregnant mother's immunity drops, it is easy to get sick, which is not good for the pregnant mother and the fetus.

Second: sad.

In foggy days, the air pressure is generally low, the oxygen content in the air drops, and people are prone to chest tightness and suffocation. Humidity and cold can also cause cold stimulation and increase heart load. In recent years, studies have shown that too thick particles in smog can harm the heart. Once inhaled excessively, it will lead to heart attack and even sudden death.

Third, it endangers the growth and development of the fetus.

Studies in the United States show that babies born to pregnant women living in highly polluted environments will lose 9% of their birth weight and 2% of their head circumference. Smog often contains some allergic particles and heavy metal particles. Excessive inhalation may induce allergy or poisoning of pregnant mothers, leading to fetal dysplasia and even malformation.

Fourth, affect the mood of pregnant mothers.

The fog is heavy, the air is dignified and the light is weak. The human body will secrete more pineal hormone, while the concentrations of thyroxine and epinephrine are relatively low. In this way, the pregnant mother's mood will become melancholy and heavy, which will affect the growth of the fetus to some extent. Therefore, for the sake of the baby's health, pregnant mommy should keep a good mood and do a good job of smog prevention in foggy days.

How do expectant mothers cope with smog weather? First of all, air pollution affects fetal development:

PM2.5 is a kind of particulate matter with aerodynamic equivalent diameter less than 2.5 microns, also known as fine particulate matter, which can reduce visibility and is the main cause of haze weather. Because of its small particle size, it absorbs or carries more toxic and harmful components. At the same time, PM2.5 stays in the air for a long time, and it is easier to enter the deep respiratory tract of human body, which is more harmful to health. Studies on pregnant women exposed to high concentrations of PM2.5 show that high concentrations of fine particles may affect the development of embryos.

There is a study in the United States that collected 48 hours of air samples from the surroundings of each pregnant mother. Use a portable air monitor during the day and put it by the bed at night. This is the first experimental study on the influence of air pollution during pregnancy on fetal prognosis. The results showed that the birth weight and head circumference of pregnant mothers living in an environment with serious air pollution decreased by 9% and 2% respectively, while the babies born to pregnant mothers with relatively good air did not change significantly. Studies have shown that air pollution is related to low birth weight and small head circumference of fetus. Research shows that environmental pollution has threatened the fetal growth in new york.

Second, keep the indoor air fresh:

1. indoors, pregnant mothers should pay attention to timely rehydration and drink plenty of water to keep the respiratory mucosa moist. In addition, there is metabolism in the body to eliminate toxins in the body.

Pay attention to personal hygiene and change clothes frequently, especially when you come back from home. There are a lot of dust and other small particles in clothes, so it is best to clean them to avoid breeding bacteria and infecting various viruses.

Pregnant mothers who stay at home for a long time will inevitably feel bored and depressed. Find something else to do at this time, such as watching TV, listening to music and reading books. Make yourself happier. You can also call your friends and chat occasionally. And do all kinds of stretching exercises indoors to keep healthy and increase immunity.

Don't close the window too tightly. Sometimes the smell of oil smoke at home and all kinds of harmful gases emitted by furniture are more harmful to the body. So when there is fog, open a small window. When the sun is shining at noon, pay attention to "breathing" indoors.

Three, outdoor activities should pay attention to protective measures:

1. Avoid going out for a walk on days with serious air pollution, such as morning exercises. In the morning, harmful substances in the air will be inhaled into the respiratory tract, thus endangering the health of pregnant mothers. You can choose to go out for a walk and bask in the sun when the sun is shining.

2. Minimize going out. When encountering dense fog, try to stay at home. If you have to go out, you'd better wear a mask. Wearing a mask can prevent some allergens such as dust mites from entering the nasal cavity. Pregnant mothers should pay attention to choose some products from regular manufacturers and change them every day. It is better to have boiled water to disinfect them.

3. Try to go to crowded places and get in touch with slimming bacteria. In addition, pregnant mothers should pay attention to keep warm in winter and wear more clothes to avoid catching a cold.

4. Conditional pregnant mothers, especially in the first trimester, can choose to give birth in areas with fresh air.

Fourth, eat more lung-clearing food:

There are tiny water droplets, dust and even pollutants in the fog. Pregnant mothers with a history of respiratory diseases such as asthma, rhinitis and chronic bronchitis must pay attention to the fact that germs attach to dust and enter the lungs with breathing, which is easy to cause respiratory diseases. Eating more fresh fruits and vegetables in foggy days can moisten the lungs, remove dryness, eliminate phlegm and relieve cough, strengthen the spleen and tonify the kidney. Eat less irritating food and eat more pears, loquats, oranges, oranges and other foods. Clearing lung and resolving phlegm.

Vitamin D can promote the absorption and utilization of calcium and phosphorus in human intestine and maintain the calcium concentration inside and outside cells. It is an auxiliary factor that cannot be ignored when supplementing calcium. Regular exposure to the sun is the best way for the human body to obtain sufficient and effective vitamin D at low cost. Due to the serious air pollution, pregnant mothers reduce the chances of going out in the sun, thus reducing the absorption of vitamin D. How can pregnant mothers supplement vitamin D? Salmon, red trout, cod liver oil, flounder cod liver oil, cream, eggs, chicken and duck liver and milk are all rich in vitamin D. Pregnant mothers should also pay attention to eating more of these foods!
