Pregnancy Stress Quiz Question 1

While exceptional levels of stress can be detrimental, research shows that moderate stress is actually good for the fetus. "Regular stress during pregnancy, such as work deadlines, probably don't add to pregnancy problems," an article from March of Dimes states. In fact, it can actually tone the fetus's nervous system and accelerate development. What's more, according to the one study, those who experienced moderate stress during pregnancy have 2-week-old infants with brains that work at a faster speed than infants of mothers without the same stress, and 2-year-old toddlers with higher motor and mental development scores.

That said, experiencing extreme stress or duress can cause health problems, like high blood pressure. It can also lower your immune system, increasing the chance of getting an infection in your uterus. For this reason, you should try and be as mindful as possible—mitigating high stress events and activities whenever you can.

Numerous studies have shown the health benefits of exercise, i.e. exercising during pregnancy boosts your mood and increases the quality of your sleep. It lowers your risk of gestational diabetes and other pregnancy complications, and it can actually reduce back pain and strain. Exercise during pregnancy is a good thing.

But did you know that when you exercise baby gets a workout, too? According to research, the heart rates of the fetuses of pregnant people who are physically active are slower and more variable, both signs of cardiovascular health. The babies of exercisers have lower birth weights and may even become more intelligent adults because of their bigger brains.

While most doctors and experts recommend side sleeping during pregnancy, some pregnant people can (and do) sleep on their back. It is a matter of comfort. It also poses minimal risk, especially in the first trimester. That said, the ACOG still recommends pregnant people sleep on their side.

"As your belly grows, sleeping on your back may not be good for you," the ACOG writes. "It puts the weight of your uterus on your spine and back muscles. In the second and third trimesters, lying on your back may compress a major blood vessel that takes blood to your uterus, making you feel dizzy and possibly reducing blood flow to your fetus. Sleeping on your side during your second and third trimesters may be best."

According to the American Pregnancy Association, deli and luncheon meats should be avoided during pregnancy. This is due to possible contamination and their high nitrate concentration. However, these foods can be consumed—in moderation—if they are properly prepared, i.e. deli meats can be eaten if they are heated to 165 degrees F or higher. This means pepperoni pizza, for example, is a safe bet.

Several studies have found that that vaginal sex during pregnancy does not increase your risk of preterm labor or premature birth. Your baby is also highly protected by amniotic fluid and your uterus. That said, if you have specific concerns, you can and should speak with your doctor.
