O que traumas da infância fazem com nossos GENES e nosso CÉREBRO?
Summary
O episódio explora a relação entre traumas na infância e transtornos mentais, detalhando como experiências traumáticas alteram a química cerebral, especificamente a produção de dopamina na amígdala. Os apresentadores discutem o conceito de epigenética, explicando como esses traumas "ligam" genes permanentemente e criam cicatrizes psicológicas. A conversa inclui reflexões pessoais sobre bullying e ansiedade social, além de recomendações para buscar terapia e entender os mecanismos biológicos por trás do sofrimento emocional.
