How Our Genetics Shape Personality and Mental Health (Season 1, Episode 6: The Mind-Body Nexus)

Tiara’s Curious Lab: Bio, Psych & Tomorrow’s Science

Why are some people naturally more anxious, while others seem effortlessly confident? Why do certain mental health conditions run in families? In this episode, we explore the fascinating world of genetics and how the DNA you inherit shapes your personality, emotions, and even your mental health.

We’ll break down what heritability really means — and why it doesn’t mean your future is set in stone. From twin studies to animal research, you’ll discover how our genes interact with our environment to make us who we are. Plus, we’ll introduce the concept of epigenetics — the science of how life experiences can actually switch certain genes on or off, influencing how we feel and behave.

Whether you’ve ever blamed “bad genes” for your quirks or wondered if your mental health was predetermined, this episode offers a hopeful perspective. You’ll learn how nature and nurture work together, and how understanding your genetic makeup can empower you to make choices that support your well-being.

Tune in to discover the surprising ways your DNA shapes your mind — and how you can still write your own story.
