Can frequent anger in pregnant women affect the intelligence of the fetus?

A pregnant woman's emotional fluctuations may affect the fetus, but not intelligence directly. If a woman experiences prolonged stress, anxiety, or frequent anger, it may lead to the release of stress hormones such as cortisol, which could be passed on to the fetus through the bloodstream. Research indicates that high stress levels may be associated with preterm birth, low birth weight, and neurodevelopmental issues in infants. Intelligence is determined by multiple factors including genetics, prenatal nutrition, maternal health, and environmental influences, rather than by a single emotional factor. It is very important for pregnant women to maintain a positive mood. Stress can be relieved through appropriate relaxation techniques such as deep breathing, yoga, meditation, or talking with family and friends. Regular prenatal checkups, a balanced diet, adequate rest, and positive psychological support all contribute to the healthy development of the fetus. If emotional distress persists, it is advisable to consult a doctor or a mental health professional for assistance.
