Prenatal stress is a research area that focuses on the impact of maternal stress during pregnancy on the developing fetus. This field of study examines how stress experienced by the mother, such as anxiety, depression, or trauma, can influence the physical and psychological health of the child later in life. Researchers study the potential mechanisms through which prenatal stress affects fetal development, such as changes in maternal hormones, placental function, and gene expression. Additionally, they explore the long-term consequences of prenatal stress on the child's behavior, cognitive abilities, and susceptibility to various health conditions. Overall, understanding the effects of prenatal stress is important for developing interventions to support pregnant women and promote optimal outcomes for both mothers and their children.
