Stress during pregnancy can have a major impact on both the mother and her developing baby. Research from NewYork-Presbyterian and Columbia University studied 187 pregnant women and found that maternal stress can affect the baby’s growth, brain development, and even whether the baby is born male or female.
When a mother experiences high stress, hormones like cortisol can cross the placenta and reach the fetus. These hormones can change how the baby’s brain develops, affecting areas responsible for learning, memory, and emotional regulation. Over time, this may increase the risk of cognitive or emotional challenges in childhood and beyond.
The study highlights the importance of supporting mental health during pregnancy. Reducing stress through rest, emotional support, and safe coping strategies can protect both mother and child. Simple steps like gentle exercise, talking with loved ones, and professional counseling can make a difference.
By understanding how stress affects pregnancy, families and healthcare providers can promote healthier outcomes and give children a better start in life. Protecting maternal well-being is not just about comfort—it directly shapes the future of the next generation.
