Prenatal stress, also known as prenatal maternal stress, occurs when an expectant mother is exposed to psychosocial or physical stress. This can be brought on by daily events or environmental hardships. [1 [2] According to the Developmental Origins of Health and Disease (DOHaD), a wide range of environmental factors a woman may experience during the perinatal period can contribute to biological impacts and changes in the fetus that then cause health risks later in the child's life.Health risks include impaired cognitive development, low birth weight, mental disorders, and gender specific deficits in the offspring.[1][2]
