We’ve heard this one too. And while nothing’s been proven on the subject yet, there are definitely lots of theories floating around out there as to why. Here are two of the biggest:
Theory 1: Mosquitoes are attracted to carbon dioxide. Later on in pregnancy, you’ll tend to breathe more heavily, releasing more air (21 percent to be exact) than non-pregnant women do. Some think the mosquitoes are drawn to the fact that you’re giving off more CO2.
Theory 2: When you’re pregnant, your body temperature rises. This increase in body heat means that your skin releases more volatile substances, which make it easier for mosquitoes to find you.
The larger amounts of carbon dioxide, mixed with the rise in body temperature, make pregnant women a feast for mosquitoes. Be sure to take precautions when you’re outside — mosquitoes can carry diseases that could be harmful to you and baby.
