Soaking in the hot tub or relaxing in a sauna may seem like the perfect way to pamper your pregnant body, but raising your core temperature—especially during the first trimester—may boost the odds of birth defects. It’s safe to soak in a lukewarm bath, though. Just make sure that the temperature is not above 100 degrees and that you get out after about ten minutes, Resnik advises. Sustained exercise in very hot, humid weather can also raise your core temperature. When you do exercise, be sure to drink liquids before, during, and after, and if you find that you’re heating up, take a five- or ten-minute breather.
Lead exposure has been linked to miscarriage, preterm labor, low birth weight, and mental and behavioral problems in children. Residue from the toxic metal can lurk in places you might not suspect: houses built before 1978 (the year lead paint was banned), tap water, even calcium supplements. A few precautions will reduce the amount of lead you come into contact with: Call in a lead-abatement specialist if you live in an older home with chipping or peeling paint. (Whatever you do, don’t try to sand or scrape it off yourself.) Filtering your water may help, or have your tap water tested. (Call the Environmental Protection Agency’s Safe Drinking Water Hotline at 800-426-4791 for a testing lab in your area.) Finally, if you take a calcium supplement, ask your doctor to recommend one that’s low in lead, such as Tums 500 Calcium Supplement.
Don’t worry, you needn’t swear off oral gratification entirely. (After all, when you hit that physically awkward last trimester, there may not be much else you can do between the sheets.) But when he’s pleasuring you, your mate should be careful not to blow air into your vagina, if that’s something that’s part of his, uh, repertoire. Why? Your blood vessels are dilated during pregnancy, and, though the chances of this happening are very rare, a fatal air bubble could potentially enter your bloodstream, McCartney explains.
Certain Over-the-Counter Drugs
Your back is aching, your heart is burning, and your stomach is roiling—do you have to forgo all pharmaceutical relief? Not necessarily, says Bradley. But since even benign-seeming remedies, such as aspirin, ibuprofen, and certain cold preparations, can cause problems for your baby, don’t pop any pill without your doctor’s approval. If one medication is off-limits, she can suggest an alternative. Acetaminophen (Tylenol), for instance, is fine.
You may have given up cigarettes, but if your mate’s still puffing away, your baby’s getting hefty doses of the 43 cancer-causing chemicals in cigarette smoke. In fact, exposure to secondhand smoke during pregnancy raises the risk of low birth weight, sudden infant death syndrome, and other health problems. So ask your partner to quit or to cut down—if not for his own health, then for yours and your baby’s. And tell anyone who lights up around you to kindly take it outside.
StressEvery time you look down, your growing belly reminds you of just how much your life will change once your baby is born. Exciting, yes. Stressful? You bet. Even so, try to take it easy. Stress causes the release of hormones that reduce blood flow to the placenta and triggers contractions, and it has been linked to miscarriage, preterm birth, and low birth weight, Bradley explains. If you hold a high-pressure job, do what you can to scale back. If you’re feeling the heat in your personal life, practice relaxation techniques, surround yourself with supportive people, and seek counseling if need be.
As is the case with its chemical relative Accutane (a prescription acne drug), high doses of vitamin A during pregnancy can cause heart and facial defects, says Resnik. How much is too much? Some studies have indicated that problems can occur when pregnant women take more than 10,000 international units (IU) a day, while others list 25,000 IUs and even 50,000 IUs as the threshold. You get a fair amount of vitamin A from the food you eat, and though the dose in your prenatal vitamin should be fine, your doctor can tell you whether it’s an excessive amount.
