What Is Autumn Anxiety? Why You Feel More Anxious in Fall

Fall is my season. My birthday lands in it. I love the shift in light, the smell of the air turning, the whole beautiful exhale of the natural world slowing down. I have never personally struggled with autumn anxiety.

But I have sat across from women who do. Every October, without fail, a client will come to a session describing this low-grade blah they can't quite name. Not dread exactly. Not sadness... More like their body knows something is shifting and their brain can't quite put a finger on it. A restlessness of sorts. A subtle tightening. An urge to cancel things they were excited about a week ago.

They think something is wrong with them. Like they should be loving this season, with its candles and coziness and pumpkin everything, and instead they're spending October feeling vaguely wired and worn out at the same time.

What I can tell them — what the research actually backs up — is that nothing is wrong with them. Their nervous system is doing exactly what nervous systems do when the world around them changes. It's recalibrating. And the recalibration has a name: autumn anxiety.

There is real neuroscience behind why fall hits differently. And once you understand what's happening in your body, you can stop fighting it and start working with it instead.

What Is a Sensory Ritual — and Why It Actually Works

What Is Autumn Anxiety?

Autumn anxiety describes the cluster of symptoms some people experience during the seasonal shift into fall: restlessness, disrupted sleep, heightened reactivity, and a vague sense of unease that seems to arrive with shorter days. It's not a clinical diagnosis — you won't find it in the DSM — but it's a popular and useful term for something many women recognize in themselves every September and October.

It's worth separating from Seasonal Affective Disorder (SAD), which is a diagnosable depressive condition affecting roughly 5% of U.S. adults, according to the American Psychiatric Association. Seasonal Affective Disorder involves persistent low mood, loss of interest in activities, and significant functional impairment. Autumn anxiety tends to look more like a nervous system on high alert: wired, watchful, and unsettled, without the full depressive picture. They can overlap, and either one deserves real support.

Why Does Fall Make Some People Feel More Anxious? The Light Connection

The nervous system runs on light. Not metaphorically, but literally.

Light signals travel from the retina directly to the brain's master body clock (the suprachiasmatic nucleus, or SCN, in the hypothalamus), which coordinates cortisol production, serotonin levels, and the sleep-wake cycle. When light exposure shifts in fall, all three begin adjusting simultaneously — and that adjustment period is when many people notice anxiety symptoms picking up.

A 2024 study in Frontiers in Neuroscience (Guindon, Murphy, Milano & Seggio) found that disrupted light exposure — particularly artificial light at night — interferes with circadian regulation and increases glucocorticoid (cortisol-related) receptor activity, which is associated with heightened stress responses. The research points to how tightly the body's stress system is woven into its light-sensing system.

Your nervous system isn't being dramatic when fall makes you feel more on edge. It's responding to a genuine environmental signal: changing light. That response can show up as heightened vigilance, disrupted sleep, or that restless hum that's hard to name.

The Shadow Season: What Your Body Already Knows

Different cultures and wisdom traditions have called this time the shadow season — the weeks around the autumn equinox and into early November when the boundary between the visible world and the quieter inner one feels more permeable.

Your body knows this season before your calendar does. The thinning light, the smell of soil and decay, the trees releasing their leaves: these are ancient signals. Your nervous system is ancient too, and it's been responding to them for a very long time.

I'm a both/and kind of woman. I believe in the nervous system science AND in the soul's orientation to the seasons. Neither cancels the other out. The seasonal shift is physiological. What we make of that threshold can also be spiritual, and treating it as both is what makes it workable.

In many traditions, this time of year is understood as an invitation rather than a problem: a threshold into the dark that clears the way for what wants to come in spring. The anxiety you feel at this threshold isn't a malfunction. It's your body knowing you're crossing into something.

How to Tell If What You're Feeling Is Autumn Anxiety

Autumn anxiety tends to look different from chronic or generalized anxiety. Seasonal anxiety is usually connected to the change of the season and often settles as the body adjusts to shorter days and a new circadian rhythm. Chronic anxiety tends to feel more constant, without a clear seasonal pattern.

Signs you may be experiencing autumn anxiety:

• A low-level restlessness or irritability that started in September or October
• Trouble sleeping, or waking between 2 and 4am with a racing mind
• Increased urge to isolate, cancel plans, or retreat
• Fatigue that feels mental more than physical
• Heightened startle response (more reactive to noise or sudden movement)
• A vague sense of dread with no clear target

If this is ringing familiar, you're not alone and you're not broken. This is the nervous system doing what it was built to do. The work isn't to make it stop. The work is to give it something to land on.

If anxiety feels severe, persistent beyond the seasonal shift, or is interfering significantly with your life, it's worth talking with a mental health professional or your doctor. Seasonal patterns can sometimes point to underlying depression, thyroid changes, or other factors worth understanding.

 

What Actually Helps Autumn Anxiety

I've been doing this work for over a decade, and the women I work with consistently find that autumn anxiety responds best to practices that speak directly to the body — not just the mind. Reading about your nervous system is useful. Talking about it is useful. But the body also needs something it can feel.

Light in the morning. Getting outside in natural morning light helps signal your SCN to anchor the day's cortisol rhythm — supporting a stress response that's better calibrated to the time of day. Even on a cloudy day, outdoor light is significantly brighter than indoor light. It doesn't have to be a long walk; ten minutes matters. This is the same mechanism the Frontiers in Neuroscience research points to: light is how the body sets its clock.

A sensory anchor at threshold moments. Thresholds are the transitions in your day: waking up, walking in the door, moving from one task to another. These are when the nervous system is most vulnerable to spiking, because transition requires adaptation. A sensory ritual at those thresholds, something your body recognizes and associates with safety, teaches your system that crossing from one thing to the next is okay.

Move the anxiety through the body, not just the mind. Autumn anxiety lives in the body — the tight jaw, the restless legs, the chest that won't fully exhale. Breathwork, somatic movement, a slow walk outside, even shaking your hands out for thirty seconds: these move the energy that thinking about your anxiety simply can't reach.

The 30-Second Threshold Practice

A threshold practice is exactly what it sounds like: a ritual small enough to fit inside the doorway between one part of your day and the next.

The core practice is this: pause, feel your feet on the floor, and take three slow exhales. That's it. You're not trying to fix anything. You're giving your nervous system a moment to register that you crossed over and you're okay.

Add a scent anchor and the practice deepens. The olfactory system — your sense of smell — has a direct pathway to the amygdala, the brain's threat-detection center, allowing scent to influence your emotional and stress response before conscious thought kicks in. That's why a particular smell can shift your state so quickly. A botanical mist with grounding notes like vetiver, cypress, and black spruce can become a body-level cue over time: safe, present, here.

I formulated North specifically as a threshold tool. She's the thing I reach for when I walk in the door after being out all day and need to come back to myself. When I'm between tasks and I can feel the low hum starting up. When the shadow season has arrived and my body needs to know it's held.

FAQs: Autumn Anxiety and the Nervous System

What is autumn anxiety?
Autumn anxiety is a popular term for the cluster of symptoms some people notice during the seasonal shift into fall — restlessness, disrupted sleep, heightened reactivity, and a low-level unease. It's not a clinical diagnosis, but it describes a real experience rooted in how the nervous system responds to changing light and seasonal transitions.

Why does my anxiety get worse in October?
The body's stress system is closely connected to its light-sensing system. As daylight decreases, the brain's internal clock begins adjusting cortisol rhythms, serotonin production, and the sleep-wake cycle simultaneously. Research from Frontiers in Neuroscience (Guindon et al., 2024) found that disrupted light exposure is associated with increased stress hormone activity. That adjustment period is when many people notice anxiety picking up.

How long does seasonal anxiety last?
This varies from person to person and depends on what's driving the symptoms. For many people, the nervous system adjusts over the course of several weeks as circadian rhythms recalibrate to shorter days. If anxiety persists past the seasonal shift, feels severe, or is significantly affecting your daily functioning, it's worth speaking with a mental health professional or your doctor.

What's the difference between autumn anxiety and seasonal depression?
Autumn anxiety tends to look like a nervous system on alert: restlessness, disrupted sleep, heightened reactivity. Seasonal Affective Disorder (SAD) is a diagnosable depressive condition characterized by persistent low mood, low energy, and loss of interest in activities, affecting roughly 5% of adults. They can overlap, and either one is worth taking seriously.

Can scent actually help with anxiety?
There's a physiological basis for it. The olfactory system has a direct pathway to the amygdala, which plays a central role in processing fear and stress responses. This allows scent to influence your emotional state quickly, before cognitive processing. Pairing a specific botanical scent with a slowed breath and a moment of stillness over time can help the nervous system associate that scent with a calmer state.

The Anxiety Is the Invitation

Here's what I've come to believe after years of sitting with women in the tender spaces of their own lives: the shadow season anxiety isn't a problem to be solved. It's a signal to be listened to.

Your body is asking you to slow down. To turn inward. To stop trying to maintain summer's pace through a season that was built for something quieter. The anxiety spikes when we resist that. When we white-knuckle through October because there's too much to do and no time to feel anything.

The threshold practices, the sensory anchors, the morning light, the slow exhales: they don't make the season easy. They make you more available to it. They keep you present enough to move through the dark instead of just waiting for it to be over.

Because on the other side of the shadow season is the thing that could only come from having gone through it. That's not a metaphor. That's autumn, doing what autumn does.

You are your own sanctuary. The tools are simply how you remember.
