Addictive personality, genetics, and lifespan trends

Dopamine: the most famous neurotransmitter that regulates pleasure, motivation, and (perhaps most importantly) addiction. When examining why our society is hooked on consuming more and more of everything – food, clothes, videos, news, vacations – it's imperative to look at how our modern environments hijack our brain's dopamine, sending it into overdrive at nearly every turn. Could taking a closer look at how our societal norms make us more vulnerable to addiction help us transition to more balanced and mindful lifestyles?

In this episode, Nate is joined by New York Times bestselling author and professor of psychiatry, Anna Lembke, to explore how modern society has "drugified" our lived experience through digital media, processed foods, and instant gratification, resulting in an environment that propagates addiction. She explains how dopamine works as our brain's reward signal and why our ancient wiring is mismatched for today's level of high-dopamine stimuli in everyday life – leading to tolerance, withdrawal, and even anhedonia. Ultimately, Anna emphasizes that addiction is not a personal failing but a predictable response to an environment designed to take advantage of our brain's neurochemistry.

What are the key practices individuals can use to reduce their addictive tendencies, even as our culture continues to prioritize quick dopamine hits and consumption? How long does it take to see the positive effects after moving away from the stimulus related to our addictive behavior? Lastly, if we acknowledge that information alone isn't enough, what cultural shifts can we make to foster more connection, digital mindfulness, and authenticity, in order to return to a slower, lower throughput way of living?
