INSIGHT

Dopamine's Role

Dopamine, a molecule in the brain, drives pleasure, motivation, and reward.
It's also central to addiction, with changes in dopamine levels correlating with addiction's progression.

INSIGHT

Pleasure-Pain Balance

Our brains seek pleasure and avoid pain, operating like a balance that tips with dopamine release.
After pleasure, dopamine downregulates below baseline, creating a dopamine deficit and prompting pain.

INSIGHT

Addiction's Rise

Addiction is becoming increasingly common due to easy access to highly rewarding stimuli.
Even populations previously considered less susceptible, like older adults and women, are experiencing increased addiction rates.

The contemporary world is saturated with ways in which we can experience rewards that were historically much more difficult to access. Although this idea of a world filled with dopamine fixes is not new, it can be continually surprising just how extreme this reality has become. Here on the show today to talk about this issue and her most recent book, Dopamine Nation, is Dr. Anna Lembke, and we have a fascinating and important conversation in which she unpacks the human body and mind in relation to the world around us at present. One of the main points from this chat is the weakness of humans, and how unaware we can be of the way our brains compel us to engage in behaviours and seek pleasure. We get into some strategies and solutions for healthier ways to exist, talking about mindfulness, awareness, and dopamine fasting, in the face of accelerating tech and overabundance. Dr. Lembke gives us a great introduction to dopamine and how it functions in our bodies, unpacks the four properties of addictive substances and activities, the different ways to frame and understand addiction, and shares some realistic ideas about moderation. So to hear all this and much more, tune in to this great episode of the Rational Reminder Podcast.
