Nostalgia plays an essential role in our mental health as we age
A song from 1978 suddenly hits, and you remember your cousin’s car, which had an 8-track player. You laugh to yourself as you sing along. You remember the smell of your first apartment and the late-night parties, where you’d switch vinyl records. You feel a warmth as you recall these memories. That’s not just your brain being sentimental. It’s one of humanity’s most sophisticated survival strategies!
As a cultural anthropologist, who mainly works at the intersection of technology and culture, nostalgia isn’t so much about living in the past as it is about using the past to live more fully in the present.
When you’re reminiscing, whether by yourself or with friends and family, your mind is doing something quite clever: it’s mining your personal and collective history for wisdom, connection, and resilience that can serve you now.
Nostalgia helps us navigate the complex world we live in, especially today, with the prevalence of social media and advanced technologies like new Artificial Intelligence (AI) tools, such as ChatGPT or Claude. Nostalgia not only helps us navigate complexity but also social change and uncertainty.
Humans are meaning-making animals. We use narratives and stories to understand our place in the world. Nostalgia helps us create and build our personal identity. Especially when we’re with friends of a similar age. Those yarns we tell of our misspent youth? They help us build social bonds and work through the issues of today.
When we share those stories and experiences with friends and even family, they form a sort of social “glue” that brings us together, often with laughter, sometimes with sadness and longing. When things feel a little unstable, it helps to get some stability in our lives.
Research has shown that when we have nostalgic memories, our body warms up! (Maybe a good idea when walking on a cold winter’s day?) So nostalgia, too, can be a sort of mental “comfort food” for our brains. It also reminds us that we’ve overcome challenges before and that we are perhaps stronger than we sometimes think.
Nostalgia also helps us create intergenerational teaching opportunities not just for our kids, but also for our grandkids, nieces, and nephews. When we say things like “back in my day,” this is a social signal that conveys authority. Sometimes, it even elicits laughter!
Nostalgia is an interesting emotion that plays an increasingly important role in our cognitive health as we age, fosters social bonds, and helps us navigate the modern world. So, next time you feel nostalgic? Lean into it. Share and find some moments of warmth and happiness.
