Some researchers suggest that a heightened sense of smell during pregnancy may be an evolutionary trait designed to help women avoid potentially unsafe foods.
Many women say that an increased sensitivity to smells, known as hyperosmia, is one of the first signs they noticed during pregnancy.

Interestingly, studies have shown that pregnant women may not necessarily smell better, but they could be more attuned to recognising and reacting to certain odours.
Early in pregnancy, just as the body may reject foods that could be harmful to a developing baby, women seem to develop a stronger reaction to smells that signal danger, such as cigarette smoke or spoiled food.
This "disgust sensitivity" might be the body’s way of offering extra protection during those crucial early weeks.
