More than Just Fun and Games: 5 Ways Social Connection Supports Longevity
By now, most of us have felt how much our social lives have shifted since pre-pandemic days. Practically overnight, we went from busy calendars and regular get-togethers to “we don’t go out anymore” and “I haven’t seen friends in ages.” Retreating was necessary for safety—but over time, that disconnection took a toll. One of the biggest casualties? Possibly our longevity.
When we think about living a long and healthy life, we tend to focus on the usual suspects: eating well, exercising, sleeping enough, managing stress. But one powerful pillar often gets overlooked—human connection. It turns out that meaningful relationships are just as essential as veggies and regular movement. That’s why I encourage my patients to rekindle connections, nurture the good ones they already have, and stay open to new ones.
Sure, it’s easier to stay home and hibernate—but if you want to live longer, healthier, and with more joy, it’s time to shake things up. Here's why social connection matters so much for your health and longevity—and some easy ways to bring more of it into your life.
Reintroduce yourself to real relationships
Let’s be clear: we’re not talking about Instagram likes, your thousands of connections on LinkedIn, a fat contact list in your phone. Social connection means real relationships — with people who make you laugh, let you be yourself, and show up when it counts. They’re the ones who lift you during tough times and make the good ones even better. Why does this matter so much? Because countless studies show that meaningful connection plays a plays a powerful, and measurable role in helping us live longer and stay healthier.
Connect for a long and healthy life, according to science.
Spending time with people you care about feels good in the moment — but the health benefits extend far beyond those moments. A 2015 meta-analysis of 70 studies and more than 3.4 million people found that those with strong social ties had a 50% greater chance of survival over time than those with weaker bonds—regardless of age, gender, or health status.
More recently, a 2023 study showed that loneliness and low social integration increase the risk of heart disease, stroke, depression, dementia, and even early death. In fact, the U.S. Surgeon General warned that poor social connection can be as damaging to your health as smoking 15 cigarettes a day. Yes, that’s how powerful your social life (or lack thereof) is. Let that idea sink in.
Lack of social connection hurts hearts and minds.
Whether you’re an introvert or an extrovert, humans are wired for connection. Over thousands of years, we’ve evolved in groups and communities, and when we feel socially isolated, our bodies react. Chronic loneliness activates the stress response, increases inflammation, weakens the immune system, and disrupts sleep and heart health. Over time, this puts the body into a state of chronic wear and tear, or ‘allostatic load,’ which accelerates aging and disease.
Connection matters even more as you age.
As we get older, our social circles often shrink. Retirement, health issues, caregiving responsibilities, or the loss of a partner can all make it harder to stay socially engaged. The trouble is older adults are the very ones who benefit most from strong social bonds—especially when it comes to brain health and independence.
Studies show that socially engaged older adults are at lower risk for lower risk for cognitive decline and are more likely to maintain mobility and autonomy. Social interaction boosts mental stimulation through novelty, conversation, emotional engagement, and even laughter. On the flip side, a 2023 study published in Nature Human Behaviour found that loneliness and poor social connection were associated with higher risk of cardiovascular disease, stroke, dementia, depression, and premature death. So, think of social connection as being like a workout for your brain. Like keeping your muscles strong, you’ve got to “use it or lose it.”
And according to the Harvard Study of Adult Development—the longest-running study on happiness and health—it’s not wealth, career success, or even genetics that predicts well-being. It’s the quality of your close relationships. Granted, great relationships may not completely slow the hands of time, but it does underscore the importance of what those relationships mean to living long and well.
Social connection matters when you’re on the younger side too.
Interestingly though, the need for connection isn’t just an elder problem, younger folks are struggling as well. According to the Journal of the American Heart Association, social isolation and loneliness throughout life can increase a person's risk of stroke and heart attack by as much as 30%. And with more people lonelier than ever across multiple age groups – including Gen Z – the fear is that these risks may surge in the not-to-distant future.
Social connection that really, well, connects.
The good news is that you don’t need boatloads of friends or social engagements five nights a week. It’s really a matter of quality over quantity. A few close, trusted, high quality relationships, as in relationships where you feel safe, supported, and accepted for who you are – can be profoundly protective for your health. It could be a spouse, a sibling, a best friend, or a long-time colleague, and again, just a few will do the trick. Even one or two solid relationships can make all the difference.
Polish your social connection skills – to make longevity shine.
You don’t have to turn your life upside down or go back to full pre-pandemic social butterfly – but I do recommend you make a few adjustments. Here are a few ways tapping into these skills, or ‘longevity tools’ can get you get back into a more connected groove:
- Show up—often.
Like exercise or sleep, social wellness thrives on consistency. A weekly walk, a recurring class, or a regular phone call counts.
- Make the first move.
Don’t wait. Send a “thinking of you” text, share a funny meme, suggest coffee. Most people appreciate the invitation—and may be waiting for someone like you to make the first move.
- Small talk matters.
Say hi to the barista, chat with your neighbor, smile at someone in yoga class. These micro-moments build a subtle but meaningful sense of belonging and connection.
- Listen like you mean it.
Make eye contact, ask real questions, reflect back what you hear. Deep listening builds deep trust.
- Join something – anything!
Try a class, club, or volunteer opportunity that aligns with your interests. Shared activity is a low-pressure way to spark connection.
- Be mindful of junk connections.
Social media can trick us into feeling connected — but passive scrolling, like empty calories, rarely satisfies. Choose quality over quantity in your digital life too.
- Open up your calendar and plan to connect.
Just like meal-prepping or scheduling workouts, planning social time helps it happen. Block out a couple of social slots per week or make a list of people you want to reconnect with – and follow through.
- Mix up ages and generations.
Conversations with someone younger or older than you add depth and resilience to your social network—and can be unexpectedly rewarding. As they say, ‘age ain’t nothing but a number’ – and friendships can (and should) be age agnostic.
BOTTOM LINE: Social connection can be a life saver – and a life enhancer.
When it comes to health and longevity, meaningful connection is as essential as any other lifestyle habit. It weaves together purpose, joy, and resilience—the very things that make life not only longer, but better. So, if you’ve been feeling a little disconnected lately, take it as a nudge: your next conversation, laugh, or shared moment might just be a powerful step toward a longer, healthier life – so start connecting!
