Circadian

We chase the sun without realizing it. The moment dawn breaks the horizon, a switch is flipped in our bodies. When light touches the retina, it signals the suprachiasmatic nucleus deep in the brain that it's time. With that single cue, a cascade begins. Melatonin production drops, cortisol level rises, and it’s this rhythm that’s been guiding us way before clocks were invented.

But it’s at the other end of the day, when the sun retreats, where I find something more mysterious. This project began as a visual exploration of sunsets, but it quickly led to a different interest: understanding what the light says to the mind. I stood on rooftops, in vast plains, on busy streets, and I watched the world dim. I noticed different lifeforms responding: plants folding in their petals, birds softening their calls, humans going to rest, and nocturnal creatures emerging and unfolding into the world like a summoning. Each response speaks to the dialogue between the organism and sun.

Sunsets aren’t just beautiful; they’re neurological triggers. Warm tones like amber and rose stimulate aesthetic pleasure, and the dimming of the light calls for the pineal gland to release melatonin, which prepares us for rest. It's no coincidence that the circadian rhythm, our 24-hour biological cycle, is synced to the sun. For millions of years, life evolved under this reliable cycle of light and dark, and the brain and body is shaped to anticipate dawn and dusk. Light became a primary cue for survival. Hunting, foraging, resting, and healing were all timed to its presence or absence. This long ancient contract tuned our bodies to the sun’s dependable rhythm, even in our modern electric world.

Sunsets even carry an emotional weight. In our brains, areas for emotions and memory often activate together. That’s why we remember sunsets, not only as sights, but as feelings of nostalgia, peace, and longing. The hippocampus links what we see to where we’ve been. That quiet ache you feel at twilight? It's your brain creating a snapshot, not only of the light, but also of time passing.

This collection is a meditation. The sun setting reminds us to slow down, shift inwards, and reflect. We’re not separate from the environment. We are part of its choreography. And the sunset, however fleeting, is one of the most universal cues, telling us it’s okay to rest.
