Every year with the first cold snap, there is a moment when the maple outside my window stops pretending.
At first, it’s green and holding on. The next day, the colors of decay start coming fast, and the leaves start letting go without ceremony.

People think autumn is beautiful. It has its own aesthetic, following, fan club. But we detach from what makes it beautiful: a tree is dying.
Autumn is the season that rehearses death for us every single year. Every single year, our ancestors practiced death alongside it. And for our ancestors, who didn’t have grief counselors or five-stage models, this was their chance to practice death alongside it. And it’s our inheritance too.
What Trees Teach Us About Grief and Letting Go
Think of a tree.
A tree in autumn isn’t fighting for its leaves. It isn’t clinging to them, trying to bargain for another few weeks of green.
This is what happens: As the days shorten chlorophyll production slows. There’s less need for them with less sun. And the chlorophyll is what gives leaves their green color. Once it fades, the golds and reds underneath, the beautiful colours who were there all along, get their turn to be seen.
So at this point the tree has slowed down. Do the leaves just fall now?
Not quite. Before the tree releases those leaves, it pulls the nutrients back into itself. The tree starts storing what it needs before letting go of what it can no longer sustain. Letting go is an act of keeping.
A relationship can end and still leave you with everything it taught you. A person can die and still remain woven through the way you tell stories, cook a meal, laugh at something ridiculous, or see the world. A chapter can close without making everything that happened inside it meaningless.
Your Body Is Doing Its Own Autumn
Your body is not a tree, but it also goes through its own autumn transformation.
Here’s where the folklore and the science hold hands, the way they often do.
As the days shorten, your body genuinely changes. Less daylight affects the rhythms that regulate sleep, mood, and energy. Melatonin may begin to rise earlier, which can leave you feeling ready for bed sooner or make mornings harder.
Changes in light exposure can also affect serotonin and other systems involved in mood. For some people, the shift is barely noticeable. For others, it can be significant.

And then there is grief.
Why Does Grief Feel Worse in Autumn?
Grief has a way of becoming louder when the world gets quieter. The long evenings of summer are gone. There is less light, less activity, and often more time spent indoors. The season itself seems to turn our attention inward.
This is why grief can sometimes resurface in autumn, even grief you thought you’d already made peace with. A certain smell, a familiar kind of light, the first cold morning, a holiday approaching, or simply the change in the air can bring someone back to you.

It’s not a coincidence that so many cultures have placed traditions of death and remembrance around this time of year. Samhain. The thinning veil. Days of the Dead. Ancestor traditions. Harvest rituals marking the end of one cycle and the beginning of another.
Before we had the language of serotonin and cortisol, people knew that the turning of the year changed something in us. They watched the light disappear earlier. They felt the pull toward darkness and rest. They watched the natural world die back and, eventually, return.
They understood something we sometimes forget: grief is not separate from the natural world. It is part of it.
