You know that feeling when you're standing in a room that is so pitch black you can't even see your own hand in front of your face? It’s disorienting. Your brain starts playing tricks on you. But then, someone cracks a door or strikes a single match. Suddenly, the room has a shape again. That's the literal version of light shining in darkness, but we're usually talking about something much deeper when we use that phrase.
Honestly, it's become a bit of a cliché. You see it on inspirational posters with sunsets or scripted into the climax of every third superhero movie. But clichés usually start because there's a fundamental truth buried under all that cheese. In 2026, where the "darkness" feels like a mix of digital burnout, global instability, and just general "vibecessity," understanding how light actually works—biologically, psychologically, and historically—is kinda essential for staying sane.
The Science of Why We Crave the Glow
Light isn't just a metaphor. It’s a physiological requirement. Our bodies are basically wired to respond to the sun via the suprachiasmatic nucleus (SCN) in the brain. When we talk about light shining in darkness, we’re often talking about the literal way our biology fights off the "dark" feelings of Seasonal Affective Disorder (SAD).
Dr. Norman Rosenthal, the psychiatrist who actually identified SAD in the 1980s, proved that light therapy could literally change brain chemistry. It’s not just "positive thinking." It’s photons hitting your retina and telling your brain to stop overproducing melatonin and start pumping out serotonin. So, if you feel like you're drowning in a dark mood, sometimes the "light" you need is quite literally a 10,000-lux lamp.
But there’s a psychological side to this, too. Human beings have a built-in "negativity bias." This is an evolutionary leftover. Back in the day, it was more important to remember where the lion was (the darkness) than where the pretty flowers were (the light). Surviving meant focusing on the threats. Today, that means our brains are naturally attracted to the "dark" news cycles, the "dark" comments on social media, and the "dark" possibilities of the future. Finding light shining in darkness in a modern context requires an active, conscious pivot. You have to fight your own biology to see the good stuff.
History’s Weirdest Examples of Light in the Dark
History is full of people who found a way to create a "glow" when things were objectively terrible. Take the "Christmas Truce" of 1914 during World War I. You’ve probably heard the sanitized version, but the reality was gritty. Men were sitting in frozen, blood-soaked trenches. Total darkness, literally and figuratively.
Then, someone lit a candle on a tiny fir tree.
That single, flickering point of light shining in darkness led to German and British soldiers—men who had been trying to kill each other hours earlier—meeting in No Man’s Land to swap cigarettes and buttons. It didn't end the war. It didn't fix the geopolitical disaster. But it provided a localized moment of humanity that proved the darkness wasn't absolute.
Or look at Viktor Frankl. He was a psychiatrist who survived the Holocaust. While in the concentration camps, he observed that the prisoners who had a "why"—a light to move toward—were the ones most likely to survive. He later wrote Man’s Search for Meaning, which basically argues that we don't just find light; we have to project it. He survived by mentally lecturing to an imaginary audience about the psychology of the camps. He created a light in his own mind because there was none in his environment.
The Physics of a Single Photon
Light is weird. It’s a wave and a particle. But the most important thing about it is that darkness isn't actually a "thing." Darkness is just the absence of light.
You can’t "pour" darkness into a lit room to make it dark. It doesn't work that way. But you can introduce a tiny amount of light into a dark room and immediately change the state of that space. Even a single photon—the smallest unit of light—can be detected by the human eye under perfect conditions.
Think about that.
The darkness can be vast, miles wide and centuries deep, but it has no physical power to "extinguish" a light. Light has to be physically blocked or the fuel source removed. As long as the source exists, the light wins the space it occupies. Every single time.
Digital Darkness and the 2026 Problem
We’re living in a weird era. We have more literal light than ever before—LEDs, screens, streetlights—but people report feeling "darker" than previous generations. This is what psychologists call "the paradox of connection."
We are constantly bathed in blue light, which messes with our sleep and ruins our circadian rhythms. This "fake light" actually contributes to a mental darkness. We’re over-stimulated but under-nourished. If you’re looking for light shining in darkness on a smartphone screen, you’re looking in the wrong place. Most of what we consume online is designed to trigger that negativity bias I mentioned earlier.

Real "light" in the digital age usually looks like:
- Turning the phone off at 9 PM to let your brain reset.
- Finding "micro-communities" where people actually support each other rather than just yelling into the void.
- Acts of "digital altruism"—using your platform to help someone else rather than just curating your own image.
How to Actually Find the Light When Things Suck
It’s easy to talk about light when things are going well. It’s much harder when you’re in the middle of a "dark night of the soul," as St. John of the Cross called it. That phrase describes a period of total spiritual or emotional desolation.
When you’re in that spot, you don’t need a sun. You just need a candle.
Expert practitioners in resilience, like those studied by the American Psychological Association (APA), suggest that "finding the light" isn't about ignoring the dark. It’s about "dual processing." This is the ability to acknowledge that yes, things are terrible, while simultaneously looking for small, manageable bits of "okay-ness."
If you try to jump straight to "everything is great!" when you’re grieving or struggling, your brain will reject it as a lie. That's toxic positivity. Instead, light shining in darkness looks like admitting: "This situation is a disaster, but this cup of coffee is actually pretty good." Or, "I don't know how I'm going to pay this bill, but my dog is really happy to see me."
These aren't just "distractions." They are anchors. They keep the darkness from becoming your entire reality.
The Myth of the "Heroic" Light
We often think the light has to be some massive, world-changing event. A huge promotion. A soulmate. A miracle.
But if you look at the most resilient people in history, their light was usually boring. It was routine. It was the "monastic" approach to life. Doing the small, right thing over and over again.
Consider the "Beautiful Soup" story from the 19th century—not the poem, but the social movements. During times of extreme poverty in London, "light" wasn't a political revolution; it was the establishment of soup kitchens that provided one warm meal. It was a localized, small-scale defiance of the darkness of hunger.
When we look for light shining in darkness, we need to stop looking at the horizon and start looking at our feet. What is the one small thing you can control right now?
Acknowledge the Shadow
We can't talk about light without talking about shadows. A shadow is actually proof that light is present. If there were no light, there would be no shadow—only total, uniform blackness.
In Jungian psychology, "the shadow" represents the parts of ourselves we don't want to see. The anger, the greed, the fear. Ignoring the shadow doesn't make it go away; it just makes it grow. The only way to deal with a shadow is to turn around and shine a light directly on it.
The same applies to our lives. If we’re afraid of the "dark" parts of our reality—debt, health issues, relationship problems—avoiding them just makes the darkness feel bigger. Shining the light (facing the truth) is terrifying at first, but it immediately shrinks the shadow. The monster under the bed is always scarier when you can't see it. Once the flashlight is on, it’s usually just a pile of laundry.
Actionable Steps to Increase the "Lumen Count" in Your Life
If you’re feeling overwhelmed by the darkness of the world or your own personal situation, stop trying to fix the whole world. It’s too big. You’re not built for that.

Start with these specific, high-leverage shifts:
- The 3:1 Ratio: Research by Dr. Barbara Fredrickson suggests that we need about three positive experiences to offset every one negative experience. If you’ve had a "dark" day, don't just go to bed. Force three tiny "light" moments. A five-minute walk, a text to a friend, or even just watching a video of a red panda. It sounds stupid. It works because it’s math.
- The "News Fast": If the "darkness" you’re feeling is global, turn off the feed. You aren't "informed" by scrolling tragedy; you're just paralyzed. Give yourself a 24-hour blackout. Notice how your internal "light" levels change when you aren't carrying the weight of 8 billion people.
- Physical Light Exposure: Especially in winter or if you work in a cubicle. Get outside within 30 minutes of waking up. Even if it’s cloudy, the lux levels outside are significantly higher than indoors. This resets your cortisol and gives you a biological "baseline" of light.
- Be the Photon: Sometimes the only way to feel the light is to give it away. Small, anonymous acts of kindness—paying for a coffee, leaving a positive review for a local business—actually create a "helper's high." It’s a chemical release that literally brightens your mood.
Ultimately, light shining in darkness isn't a passive event. It’s something you participate in. It’s a choice to stop staring at the void and start looking for the spark. The darkness might be loud, but the light is persistent. It’s been here since the beginning, and it’s not going anywhere.
Turn on a lamp. Call a friend. Face the shadow. The darkness only wins if you stop looking for the light.
