Not all activities or food and beverages consumption are allowed during pregnancy. Whatever thing done or consumed by pregnant women can affect pregnancy and the condition of the fetus.
According to time, there are five things pregnant women are not allowed to do.
World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) encouraged women who are pregnant to not consume alcohol.
This is because alcohol consumption during pregnancy may increase the risk of miscarriage and premature birth. Heavy drinkers are associated with fetal alcohol syndrome which symptoms include defect on the face, low IQ, mental retardation, poor coordination, aggressive behavior and other problems.
Caffeine can cross the placenta which increases heart rate and fetal breathing. One thing to worry is that caffeine can reduce the absorption of iron in the mother which could theoretically lead to anemia. Because pregnant women susceptible to anemia, caffeine can give a bad effect and aggravate the situation, such as dizziness, fatigue and irregular heartbeat.
Studies in 2008, published in the American Journal of Obstetrics and Gynecology found that consumption of more than 200 mg of caffeine (about 10 ounces of coffee) per day could double the risk of miscarriage at 71 days of pregnancy. Another study found that caffeine consumption is associated with cryptorchidism in male infants.
Hot tub (hot bath)
To avoid the increase of the body core temperature which can affect fetal development and the risk of miscarriage, especially during the first trimester, hot water bath can also lead to dehydration and increased heart rate. Therefore hot tubs or saunas should be avoided.
In addition, women who live in hot climates should be more careful to prevent overheating by staying indoors, use air conditioning and avoid hot air.
A study in 2005 which was supported by the National Institutes of Health found an association between a mother who colored her hair before or during pregnancy with the increased risk of neuroblastoma, which is one type of cancer in children. However, the exact cause is not known, so it needs further study.
Yet American Pregnancy Association says a little dye in contact with the skin can be absorbed by the body of the mother and into the bloodstream.
Some specific health conditions during pregnancy can pose a risk during air travel. For example, hypertension during pregnancy (preeclampsia) may increase the risk of blood clots that eventually led to deep vein thrombosis.
Meanwhile, a study in 1999 found that air workers have a higher risk of miscarriage during the first trimester. Therefore before pregnant women travels by plane, be sure to check health condition and the fetus’ health first.
