Think about how often you check one of your many social media accounts. Chances are you spend a pretty good portion of your time, productivity, and brain power participating in these apps each day. Though it may seem harmless, or even beneficial, the ubiquitous use of social media is working against our health. Our brains evolved to process social cues from real people; the more we’re on social media the less we’re having real-world interactions that challenge and support our cognition.

My guest on this week’s episode of The Doctor’s Farmacy has never had a social media account—and he’s managed to thrive! Cal Newport is an associate professor of computer science at Georgetown University and writes about the impact of technological innovations on our culture. Newport is the author of six books, including Digital Minimalism and Deep Work. As we dive into the topic of social media, Cal shares his expertise on how it’s impacting public health and culture in ways much greater than you might expect.
