De: TJ Power

Narrado por: Tj Power

A neuroscientist’s powerful framework for enhancing quality of life through the regulation of four key hormones: Dopamine, Oxytocin, Serotonin, and Endorphins (DOSE).

The brain’s ability to change and adapt is one of the most powerful tools we can harness to improve our lives. Renowned neuroscientist and co-founder of Neurify, Tj Power, believes in the human ability to optimize and rewire brain chemistry to unlock one’s full potential. However, to do so, one must first implement a series of practical, life-changing strategies.

The DOSE Effect reveals the secrets of our brain chemistry, offering simple and accessible ways to make modifications to your lifestyle that can transform your brain. Drawing on cutting-edge science, Power explores how biohacking your brain can not only enhance cognitive performance but also improve the aspects of your life that ultimately control a happier, healthier, and more productive lifestyle.

The DOSE Effect proves the intrinsic connection between lifestyle factors and mental and physical well-being. Split into four sections, this essential guidebook provides the most effective techniques for understanding the key hormones that rule our thinking and our behaviors:

1. Dopamine: your motivation and attention chemical
2. Oxytocin: your relationships and confidence chemical
3. Serotonin: your mood and energy levels chemical
4. Endorphins: your stress reduction chemical

Research-driven and deeply inspiring, Power’s revolutionary strategies allow readers to harness behaviors and practices to improve mental health, manage stress, elevate mood, and promote overall wellness. His key findings include the influence of effortful activity on Dopamine production, the significance of social connection in Oxytocin levels, the value of connecting with nature and maintaining gut health for optimal Serotonin levels, and the beneficial effects of physical exertion and laughter on Endorphins release. You have everything you need to optimize your brain chemistry—this groundbreaking book shows you how.

Good information

I loved what I learned from this audiobook, I did feel most of the tasks assigned to the listener were not aimed towards parents. Things that are easier to abide by if you don’t have children as a responsibility, such as “get outside within 30 minutes of waking up, or stretch routine upon waking up” usually my children wake before me and I have zero time to myself. Or putting all your phones in the center of the table and first person to pick up their phone pays the tab… I have kids most likely being watched at a baby sitters, so I’m probably going to pay the tab bc I’m going to check my texts and VM’s.

Amazingl and relatable! Everyone needs to listen!

This audio book is AMAZING. TJ (the author) narrates it and you can hear how passionate and enthused he is about this topic. It feels like you have your own personal coach in your pocket. I love how he describes everything in such a relatable and non-shameful way. This is such a positive book with clear snd easy to follow action steps that you can Implement daily to Improve your neurohealth. I love all the added bonus extras you get with the audio book as well. A Side note- the interview he does with his girlfriend Georgia is so sweet.

The DOSE Effect: Practical Neuroscience

TJ Power’s The DOSE Effect is a brilliantly structured, research-backed guide to optimizing the brain’s four key neurochemicals—Dopamine, Oxytocin, Serotonin, and Endorphins. As a neuroscientist, Power distills complex science into accessible, actionable strategies, offering practical exercises for each neurochemical. His insights into dopamine, social media addiction, and modern attention deficits are particularly eye-opening. Unlike theoretical self-help books, this one delivers tangible tools for improving motivation, focus, and well-being. I’ve already integrated several of these exercises into my daily routine with noticeable benefits. A must-read (or listen) for anyone seeking lasting cognitive and emotional balance.

Great book! Love all the extras at the end!

This book has great information and is written in a way that’s understandable for anyone. I especially love that he summarizes each chapter at the end of the chapter, so if you are listening as you drive and miss something or listen over multiple days you get a reminder of what the whole chapter covered.

You need this book

Power combines solid science with common sense to offer methods for a healthy lifestyle. I’ve been a nurse for many years and have always known that dopamine, oxytocin, serotonin and endorphins affect our overall well being but never really understood why. Powers not only explains why but gives simple and effective exercises to maximize their effectiveness. Truly unbelievable.
