Habits of a Happy Brain: Retrain Your Brain to Boost Your Serotonin, Dopamine, Oxytocin, & Endorphin Levels Author: Loretta Graziano Breuning, PhD

Habits of a Happy Brain by Loretta Graziano Breuning, PhD, is a lively and science-backed guide to cultivating happiness from the inside out. By decoding how your brain releases the four key happiness chemicals—serotonin, dopamine, oxytocin, and endorphins—Breuning offers an empowering toolkit to create lasting emotional well-being through simple, repeatable habits.

Drawing on evolutionary biology and neuropsychology, Breuning explains:

Why your brain evolved to reward survival behaviors—not just pleasure

How natural chemical highs are triggered and why they don’t last

Ways to replace destructive patterns with healthy, uplifting habits

Daily practices to stimulate each feel-good chemical

Why societal norms often conflict with biological impulses—and how to manage that tension

From short bursts of productivity (dopamine) to nurturing relationships (oxytocin), each chapter explores techniques to consciously train your brain. Breuning uses relatable examples, quirky illustrations, and practical exercises to demystify neuroscience and make self-regulation accessible to all.

The colorful cover, adorned with playful neural networks and highlighted neurotransmitter names, reflects the book’s vibrant promise: happiness isn’t elusive—it’s programmable.

Whether you're battling stress, navigating emotional ups and downs, or simply want to upgrade your mindset, Habits of a Happy Brain delivers a joyful roadmap to retrain your mind for lasting positivity. It's especially valuable for wellness coaches, educators, and readers curious about the overlap between science and self-help.
