85:: The science of gratitude (& using gratitude to rewire your brain!)

Gratitude isn’t just a “feel-good” emotion—it’s a scientifically backed practice that can rewire your brain, balance your hormones, improve your sleep, and even strengthen your heart. In this episode, we explore the various ways to practice gratitude and how to make it a meaningful part of your daily life.

You’ll learn about three core types of gratitude:

Gratitude Awareness: Simple ways to journal or meditate on what you’re thankful for—because “I’m grateful for…” is more powerful than it sounds.
Gratitude Experience: How to feel gratitude on a deeper level by putting yourself in the shoes of others—like the inspiring story of Dick and Rick Hoyt, the father-son Ironman duo whose bond shows what gratitude in motion truly looks like.
Gratitude Giving: Why expressing your appreciation out loud or writing a gratitude letter can shift your mindset, boost your mood, and strengthen your relationships.

We also dive into the science of gratitude—including how it changes your brain chemistry and physiology:

Increased dopamine and serotonin for motivation, happiness, and emotional balance
Oxytocin release for deeper social connection
Reduced cortisol (up to 23%) and inflammation, improving both your nervous system and heart health
Enhanced sleep quality, HRV, and even longevity

You’ll hear about landmark studies (like Emmons & McCullough, 2003) and new 2024 research showing gratitude’s effects on cortisol, cardiovascular function, and even lifespan—especially for women.

Whether you’re journaling, meditating, or sharing your appreciation with others, this episode will help you understand why gratitude works, how to practice it effectively, and what happens to your brain and body when you do.

Tune in to learn how something as simple as saying “thank you” can reshape your health, your mindset, and your relationships.
