It's generally safe to use perfume during pregnancy, but you may be more sensitive to fragrances and find that some scents make you nauseous, dizzy, agitated, or more prone to headaches. Studies in rats have shown that the mother wearing perfume can cause fertility issues in the offspring, although this has not been supported by human studies. To be on the safe side, it's best to choose a natural or chemical-free scent. If you decide to wear perfume, finding one that embodies the way you want to feel during pregnancy can be a lot of fun.
Most doctors believe that the chemicals in deodorants and perfumes remain on the surface of the skin and don't penetrate deep enough to cause harm to the mother or fetus. However, your sense of smell may increase during pregnancy and your skin may be more sensitive, so proceed with caution when applying perfume. Natural perfumes are a great alternative to chemical-laden ones, as they are less likely to trigger an allergic reaction. It's important to avoid overusing deodorants and perfumes during pregnancy, especially if you also enjoy scented lotions and creams.
Safer essential oils such as diluted citrus oil can be used instead of fragrant deodorants and perfumes. If you're using conventional perfumes, make sure they don't contain phthalates and read the ingredients carefully.
