Alcohol
World Health Organization (WHO) and the center of disease control and prevention (CDC) encourages women who are pregnant to not consume a drop of alcohol.

This is because the consumption of alcohol during pregnancy may increase the risk of miscarriage and premature birth. Heavy drinkers is associated with fetal alcohol syndrome whose symptoms include the defect on the face, low IQ, mental retardation, poor coordination, aggressive behavior and other problems.

Caffeine

Caffeine can cross the placenta thus increasing 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, the caffeine can give a bad effect and aggravate the condition such as dizziness, fatigue and irregular heartbeat.

2008 study published in the American Journal of Obstetrics and Gynecology found consumption of more than 200 mg of caffeine (about 10 ounces of coffee) per day can double the risk of miscarriage at 71 days gestation. Other studies show caffeine consumption associated with cryptorchidism (undescended testes) in male infants.

Hot tubs (hot bath)

The goal is to avoid an increase in body core temperature which can affect fetal development and the risk of miscarriage, especially during the first trimester, and hot tubs can also lead to dehydration and increased heart rate. Therefore bath hot tubs or saunas should be avoided.

In addition, women who live in hot climates should be more careful so as not too hot by staying indoors, use air conditioning and escape the heat.

Hair Coloring

A 2005 study supported by the National Institutes of Health found an association between maternal hair dye before or during pregnancy can increase the risk of neuroblastoma, which is one type of cancer in children. However, the exact cause is not yet clearly known, so it needs further study dilakuakn.

Yet the American Pregnancy Association says a little dye in contact with the mother’s skin can be absorbed by the body and into the bloodstream.

Air travel

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 will lead to venous thrombosis (deep vein thrombosis).

Meanwhile, a study in 1999 found the air workers have a higher risk of miscarriage during the first trimester. Therefore before pregnant women traveling by plane, be sure to check the condition and health of the fetus first.
