Emotional Regulation 101 for Neurodivergent People: Navigating the Seasonal Shift

As the air is getting cooler, the days shorter, and routines are starting to change. There is a sense of comfortability for some, as fall rolls in; associated with feelings of coziness and an invitation to slow down. However, for many of us who are neurodivergent, the transition into colder months brings a subtle unease. Our nervous systems tend to be more sensitive, not because something is wrong, but because our brains process and respond to stimuli more deeply. The shift to shorter days, fluctuating temperatures, and holiday disruptions can feel unsettling, amplifying the effort it takes to stay emotionally regulated. You may notice more exhaustion, mood shifts, or difficulty focusing. That’s not failure, it’s biology.

Why Seasonal Change Hits Differently

As the days shorten, our brain chemistry shifts. Reduced sunlight decreases serotonin production (which supports stable mood) and disrupts melatonin balance, our cue for sleep and energy.

For neurodivergent individuals, especially those with ADHD or autism, these natural changes can collide with existing sensitivities in profound ways.

•   Light and Sensory Sensitivity
Research shows that up to 75% of autistic people experience light sensitivity. The dimness of winter or harsh indoor fluorescents can significantly affect focus and mood regulation. Similarly, ADHD traits increase vulnerability to seasonal rhythm changes; difficulty waking, oversleeping, or loss of motivation are common.

•   Disrupted Circadian Rhythms
The shorter daylight window can throw off internal clocks. Studies show that people with ADHD traits show a stronger correlation between decreased daylight and emotional dysregulation compared to neurotypical peers.

•   Sensory Overload and Routine Disturbance
Seasonal changes bring new textures, sounds, and routines; wet clothing, stronger scents, cooler air, and holiday social pressures. These can easily overwhelm neurodivergent systems that rely on consistency for safety.

•   Seasonal Affective Disorder (SAD)
SAD affects nearly 5% of the U.S. adult population and is more pronounced in those at higher latitudes. For neurodivergent individuals, who may already battle low dopamine or interoceptive awareness issues, the winter slowdown can deepen dysregulation. Combined with sensory sensitivities and routine disruption, winter can feel disorienting rather than cozy.

What you can do about it?

Step One: Acknowledge the Rhythms

Regulation begins with recognition.
The world is slowing down and your body likely feels it too.

Instead of pushing against it, gently name what’s happening.
“I feel low-energy today.”
“I’m craving more quiet.”
“These shorter days feel heavy.”

This awareness resets the internal dialogue from shame (“Why am I so tired?”) to compassion (“My neurobiology is adjusting to less light”). Studies consistently link mindful self-awareness with decreased seasonal mood symptoms.

Step Two: Support Your Body’s Internal Clock

Your circadian rhythm thrives on consistency and light exposure. For neurodivergent people, whose body clocks may already run late, supporting that rhythm is essential. Evidence-informed adjustments include:

•   Morning light exposure: Spend 10–15 minutes by a bright window upon waking or use a clinically tested light therapy device to simulate sunlight. Studies confirm light exposure boosts serotonin and reduces SAD symptoms.

•   Warm sensory rituals: Wrap yourself in a weighted or heated blanket to provide proprioceptive input during dark mornings. This signals safety to your nervous system.

•   Stable routines: Keep meal times, bedtime, and morning routines predictable, even when the world outside feels uncertain. Regularity reduces cortisol fluctuation and improves energy balance.

Step Three: Build a Cozy Regulation Toolkit

Colder months provide the perfect opportunity to create sensory-friendly comfort that invites your body into balance. Try mixing evidence-based somatic and sensory strategies:

•   Weighted or compression wear can create a gentle, calming pressure  that helps soothe ADHD and ASD-related dysregulation.

•   Temperature comfort: Try a warm bath or dip your hands in warm and cool water to help your body reset and find balance.

•   Soothing scents and sounds: Earthy or woody aromas and steady background sounds, like brown noise, can create a sense of calm and help ease the overstimulation that often comes with seasonal changes.

•   Gentle movement: Light activity like stretching, yoga, or a short walk can lift your mood, re-energize your body, and support a more balanced emotional state.

Creating an intentional “emotional first-aid kit” helps you externalize regulation which is essential for neurodivergent people whose executive function may fluctuate with light levels and fatigue.

Step Four: Reconnect Through Structure and Rest

As the daylight fades, our systems crave rhythm. For many neurodivergent brains, winter offers a built-in invitation to slow down without guilt. When things feel chaotic, creating a ritual like lighting a candle every evening or journaling after work helps anchor your nervous system.

Rest doesn’t signal weakness; it signals regulation. The nervous system restores balance during downtime, and studies show that downtime supports emotional resilience, especially for those prone to overactivity and overstimulation.

Step Five: Nurture Connection and Co-Regulation

Isolation risk increases in winter, which can amplify dysregulation and seasonal depression. For neurodivergent individuals who already exert extra energy navigating social interactions, it’s important to connect safely, not constantly.

This might look like:

•   Text or voice note exchanges instead of video calls.

•   Attending structured, low-sensory community events.

•   Cuddling with pets or spending time with familiar people whose presence soothes rather than drains you.

Feeling safe and connected, whether through touch, presence, or trusted relationships, helps the body find its balance and steadies our emotions.

The Bottom Line: Your Nervous System Is Seasonal, Too

So when your energy dips or your emotions feel louder this season, remember: nothing is “wrong.” Your neurodivergent nervous system is simply responding, accurately, to environmental change.

The path to emotional regulation this season isn’t about fighting the darkness. It’s about working with it.
Leaning into warmth, pattern, and gentleness offers something more enduring than perfection: steadiness.

Your emotions, like the earth itself, have seasons. Honor the cycle and let your healing match the rhythm of the world turning slower.
