Why Christmas Lights Are Actually An Ancient Survival Mechanism

Transcript:

Have you ever noticed how every December we collectively decide it’s time to wrap our homes, our streets, sometimes even entire cities in tiny glowing lights? Dome of these traditions come from religious practices, but even if you strip all of that away, humans would still be doing this. Because the real story behind winter lights is much older and much more human.

In winter, most of the world is dark. Really dark. Humans evolved environments where light meant safety. You could see predators, see each other. So when the days grew short, ancient communities didn’t just complain about it. They responded. They created rituals of light. Long before electricity and long before any modern holiday existed, people lit fires and candles during the darkest part of the year. Not because it looked cute on social media, because it was symbolic. Light was a reminder that the darkness wouldn’t last forever. Across cultures, you see the same instinct. Lanterns, bonfires, candles placed in windows, torches carried through villages, all saying the same thing.

We’re still here and brighter days are coming. It wasn’t about decoration. It was about reassurance.

Then, in the late 1800s, something changed. Electricity. The very first string lights appeared in the 1880s. They were incredibly expensive, so only the wealthy could use them. Early in the 20th century, light strings became affordable. And suddenly, lighting up the winter wasn’t just symbolic. It was beautiful. Mesmerizing. It was a public celebration.

Cities put them on trees. Department stores put them in windows. People decorated their homes. Not because they had to, but because it made winter feel magical.

Today, we know that light affects us in measurable ways. Soft, warm lighting reduces stress hormones. It makes us feel safer. It increases social connection and even boosts our mood during darker months. So when we string lights across porches or hang glowing shapes in our windows, it’s not just decoration. It’s a gesture of comfort, a tiny act of defiance against the darkness of winter. And a reminder to ourselves, to our communities, that we can create warmth, even when nature doesn’t.

So why do we put lights up everywhere in December? Because humans have always done this. When the world gets darker, we make our own light. It’s ancient. It’s psychological. It’s comforting. And honestly, look around. It’s beautiful.
