A close friend came over to my house, saw the mood light in my small room, and said with a laugh, “Isn’t this the definition of a pretty piece of junk?” They were fascinated as I changed the colors and adjusted the speed of the waves with the remote, but they couldn’t seem to shake their doubts about the object’s ‘usefulness.’ It’s a completely understandable reaction. After all, it doesn’t offer a clear function like cutting or cleaning something.

However, thanks to that ‘pretty piece of junk,’ I’ve been rescued from several listless nights and comforted on sleepless dawns filled with anxiety. It has no visible function, but it was clearly creating a tangible ripple in the invisible world of my emotions. Perhaps we’ve been judging the value of ‘useful things’ solely by visible results for too long.

The Science of How Light Sculpts Emotion

When a space changes, so do our emotions. And the fastest, most dramatic way to change the atmosphere of a space is with ‘light.’ This isn’t just a matter of mood; it’s a fact based on brain science. The color and brightness of light directly affect our hypothalamus, regulating hormone secretion.

For example, blue light (high color temperature), similar to midday sunlight, stimulates the secretion of ‘serotonin,’ the happiness hormone, and suppresses ‘melatonin,’ which induces sleep. That’s why blue lighting can increase concentration and vitality. Conversely, reddish light (low color temperature), like a sunset, helps the body and mind relax and prepare for sleep by promoting melatonin production.

In fact, color psychology tells us that blue provides a sense of psychological stability and relieves stress, while green soothes tired eyes and calms the mind. It’s the same principle that makes us feel relaxed when we look at a forest or the sea. The ‘16-color LED sea mood light’ I have brings this very principle into my small room, allowing it to function as my own emotional regulation tool.

From ‘Pretty Junk’ to ‘My Own Tool’

Philosopher Martin Heidegger distinguished two ways in which objects relate to us: as something merely ‘present-at-hand’ (Vorhandenheit) and as a ‘ready-to-hand’ tool (Zuhandenheit) that gains meaning only when used for a purpose. A hammer, in itself, is a combination of wood and steel, but it acquires its true meaning as a ‘hammer’ only when you pick it up to drive a nail.

In my friend’s eyes, my mood light was just a pretty ‘present-at-hand’ object. But for me, it’s a ‘ready-to-hand’ tool that drives a nail of peace into my anxious heart and paints a color of vitality onto my listless emotions. The act of pressing the remote to make a deep cobalt-blue wave flow slowly is not just about decorating the room; it’s a conscious declaration: ‘From now on, I will calm my mind.’ In that moment, this small machine transcends being a mere piece of plastic and becomes a special being that communicates with me.

Practical Tip: Time to Create Your Own Sea

If you find yourself tossing and turning with an unknown anxiety or feeling listless from a repetitive routine, why not try the small experiment of changing the lighting in your room? It doesn’t have to be a major interior renovation. A small accessory like a ‘16-color LED sea mood light’ is enough.

• When you’re anxious and your mind is cluttered: Set it to a deep ocean blue or a calming forest green, and let the waves flow slowly. As you let your gaze rest on the gentle movement of light spreading throughout the room, you’ll feel your breathing stabilize and your mind calm down.
• When you’re feeling listless and down: Try a warm, sunset-orange or a combination of purple and green that evokes a soft aurora. The novel and mysterious combination of colors can provide new stimulation to your brain, helping to awaken dormant senses and creativity.
• On sleepless nights: A soft, reddish light helps with sleep as it doesn’t interfere with melatonin production. Use the timer function to have it turn off automatically after an hour or two, and you can drift off to sleep comfortably.

The Courage to Gain the Unseen

When we gain something, it doesn’t always have to be a tangible, material object. Intangible values like peace of mind, deep rest, and the small vitality to face tomorrow sometimes make us stronger than any material wealth.

The phrase ‘pretty piece of junk’ might be the violent gaze of a world that demands only visible usefulness. Do you have any objects in your space that are misunderstood in this way? Tonight, why not discover the invisible value that only that object can give you? With just the courage to bring a small sea into your room, more things than you think can change.
