There’s something about September that feels like an emotional rollercoaster. The crisp air. The earlier sunsets. The sudden urge to buy a dozen cozy candles you don’t need (but, let’s be real, will absolutely buy). Autumn energy is powerful—and whether you love it or dread it, the change of seasons can have a real impact on your mood, motivation, and overall mental health.

If you’ve ever noticed that your energy shifts with the seasons, you’re not imagining it. Science—and lived experience—tell us that humans are deeply affected by environmental changes like light, temperature, and even cultural rhythms (hello, back-to-school and “pumpkin spice everything” season). And for neurodivergent folx, or anyone already juggling stress and overwhelm, seasonal changes can feel like a blessing, a curse, or—most often—a confusing mix of both.

So, let’s talk about what “autumn energy” is, why it affects us, and how you can ride the wave instead of getting knocked over by it.

Why Seasonal Changes Hit So Hard

First things first: your brain and body are wired to notice changes in the environment. When the days get shorter and darker, your circadian rhythm (aka your internal clock) shifts. Less daylight means your body produces more melatonin (the sleep hormone) and less serotonin (the “feel-good” neurotransmitter).

Translation: you might feel sluggish, moody, or like you want to crawl under a blanket with zero intentions of resurfacing until April.

For some, this shows up as seasonal affective disorder (SAD), which is a type of depression tied to seasonal shifts. For others, it’s more subtle: a dip in energy, more irritability, or just feeling “off.” And then, ironically, some people feel better in the fall. Cooler weather, cozy routines, and the cultural “fresh start” of September can actually boost motivation and mental clarity.

So if you’re wondering, “Why do I suddenly want to organize my pantry and also cry about nothing?”—you’re not broken. You’re just human.

The “Fresh Start Effect” of Fall

Here’s something interesting: research shows that humans love symbolic “fresh starts.” That’s why New Year’s resolutions are a thing. But September actually gives us another dose of that same energy. Maybe it’s left over from years of back-to-school transitions, or maybe it’s just how our brains love to mark time, but fall often feels like a natural reset button.

That’s great news if you’re someone who thrives on new beginnings. You might feel a surge of motivation to set new goals, tackle projects, or finally start that hobby you’ve been daydreaming about since May. But here’s the catch: the fresh start effect can also trigger overwhelm. Suddenly, you’re signing up for too many commitments, joining three book clubs, and deciding that this will be the season you become a person who wakes up at 5 a.m. to meditate AND exercise. Spoiler: maybeeee not sustainable.

Why Autumn Energy Can Feel… Complicated

The thing about fall is that it holds two opposite vibes at once:

• On one hand, it’s crisp, inspiring, and motivating.

• On the other, it’s darkening, slowing, and kind of melancholy.

This push-and-pull can leave you feeling conflicted. You may want to be productive but also desperately want to rest. You may crave cozy routines but feel stressed by new responsibilities. And if you’re neurodivergent, those competing signals can be especially disorienting.

For example:

• ADHD brains may love the novelty of new routines but struggle with actually maintaining them once the initial excitement wears off.

• Autistic folks may find seasonal changes jarring due to shifts in sensory experiences—like scratchy sweaters, noisy school environments, or unpredictable weather.

• And anyone balancing parenting, high demand careers, and daily life may just feel like fall demands way more energy than it gives.

How to Work With Autumn Energy Instead of Against It

The good news: you don’t have to let seasonal shifts control you. By noticing how autumn impacts you, you can create routines and rituals that support your mental health instead of draining it.

Here are some practical, therapist-approved (and human-approved) strategies:

1. Pay Attention to Your Patterns

Think back to previous falls. Do you usually feel more energized in September, or do you start sliding into the winter blues? Do you overcommit in October, only to crash in November? Knowing your personal patterns helps you plan ahead.

2. Light Matters (a Lot)

If shorter days mess with your mood, light therapy lamps can be a game-changer. Even just spending more time outdoors during daylight hours can help. Bonus: walking outside among crunchy leaves is basically free therapy.

3. Lean Into Cozy, Not Overdrive

It’s tempting to take on too much when the “fresh start” energy hits. Instead, choose one or two things you actually care about and focus on those. Then balance them with cozy rituals—think: hot drinks, favorite blankets, comforting routines that make darker days feel nourishing instead of heavy.

4. Create Gentle Structure

Neurodivergent brains in particular thrive with structure, but rigid schedules can backfire. Try “gentle structure”: set anchor points in your day (like morning coffee, a midday walk, or winding down with a favorite show) to help you feel grounded without feeling trapped.

5. Plan for Rest On Purpose

Don’t wait until burnout forces you to collapse. Schedule downtime. Yes, actually write it into your calendar like it’s a meeting. Rest is not optional—it’s fuel.

When Autumn Feels Heavy

If fall always feels like a struggle, you’re not alone. Seasonal affective disorder, depression, and anxiety can all worsen in the autumn months. The good news is, support is available. Therapy can help you navigate these changes, learn coping tools, and figure out how to harness seasonal energy in ways that fit your life.

And let’s be honest—sometimes just having someone to say “yep, this is hard and you’re not crazy for feeling it” makes a huge difference.

Final Thoughts: Making Peace With Autumn Energy

Here’s the truth: autumn doesn’t have to be all-or-nothing. You don’t have to reinvent your entire life because the leaves are changing. You also don’t have to dread the darker days as if they’re a countdown to misery.

Instead, try to notice how the season impacts you—without judgment. Maybe you’ll find extra motivation in September. Maybe you’ll feel slower and more reflective. Maybe you’ll feel both at once, and that’s okay too.

The changing seasons remind us that life isn’t static. Energy rises, falls, and shifts. The trick isn’t to fight it, but to flow with it—finding ways to support your mood, motivation, and mental health along the way.

So go ahead: light that candle, pull out the cozy socks, and give yourself permission to enjoy (or grumble about) the season in whatever way feels right. Autumn is complicated. But so are we. And that’s kind of beautiful.
