Pregnancy can be difficult at any time of the year, but carrying extra weight around in the warm summer months just adds to the difficulty. It’s especially important for pregnant women to stay hydrated in order to maintain the extra blood volume that is a part of pregnancy. Dehydration can lead to preterm contractions and even fainting. It’s also important to know your limitations and to listen to what your body is telling you. If you feel uncomfortable outside during the hot summer months, look for shade or go inside to cool down.
