Monitoring our macros, steps or sleep (maybe with a wearable?) might come to mind if one wants to optimize their well-being. But there’s another factor often gets overlooked in hacking our health: social connection. And, as a society, we’re currently lacking it. One in three Americans report feeling lonely every week, according to an American Psychiatric Association poll — and 30% of Americans age 18-34 say they feel lonely every day. Building a strong, meaningful social network (IRL, not online) can be as significant for our health as quitting smoking or losing weight. But what counts as meaningful connection — and can small talk, texting and casual interactions really make a difference? This episode explores how social connection shapes our mental and physical well-being, why loneliness and isolation aren’t the same thing, and how to build healthier, more authentic connections in everyday life.

Expert: Dr. Olivia Tomasco, primary care doctor

• What loneliness is and how it differs from isolation 
• Why loneliness can affect both mental and physical health 
• Who is most at risk for social disconnection? 
• When technology helps connection — and when it may make loneliness worse

• What a healthy, supportive connection actually looks like 
• Whether texting, memes and other digital check-ins really count 
• How to make new connections in more authentic, low-pressure ways 
• When loneliness may be a sign it’s time to seek professional help
