Why Your Neurodivergent Nervous System Can’t Calm Down (Even When You’re Exhausted)
You feel like you haven’t stopped in days.
Your body is heavy, your brain is foggy — and yet you can’t settle.
You lie down and your thoughts speed up.
You finally sit on the sofa and your legs want to move.
You try to rest, but end up scrolling, researching, snacking, or pacing.
If you’re autistic, ADHD, AuDHD or otherwise neurodivergent, this “wired and tired” state is very common. It’s not just stress, and it’s not simply “bad sleep hygiene”. It’s a sign that your nervous system is over-activated and under-resourced at the same time.
This article explores:
- what “wired and tired” actually means in the body
- why it’s so common in ND adults
- how sensory load, emotions and executive function feed into it
- practical ways to move toward a calmer state without demanding huge changes or discipline you don’t have
🧠 What “Wired and Tired” Really Means for Your Nervous System
“Wired and tired” is a short way of saying:
🧩 Your body and brain are in high alert mode,
🪫 but your energy reserves are low.
You might notice:
🌧 Feeling exhausted but unable to switch off
🌪 Thoughts that race, loop or jump around when you try to rest
🧷 A mix of physical tension (jaw, shoulders, chest) and heavy limbs
⏰ Difficulty falling asleep, or sleeping but waking unrefreshed
📱 Using screens or busy activities to avoid being alone with your thoughts
This isn’t you being dramatic. It’s a nervous system stuck between:
🔥 “Be ready for danger / more demands”
and
💤 “We need to shut down and recover”.
Instead of cycling smoothly between activation (doing) and deactivation (rest), your system gets stuck in a high-alert-but-empty state.
🌡 The Autonomic Nervous System: Why It Won’t Stand Down
A lot of this comes down to how your autonomic nervous system (ANS) works. That’s the part of your nervous system that:
- speeds you up when something is demanding or threatening
- slows you down when it’s safe to rest
Very roughly:
🚨 Sympathetic branch → “go mode”, fight/flight
🌿 Parasympathetic branch → “rest, digest, repair”
In a more typical pattern, your ANS:
🌅 ramps up for effort (work, socialising, dealing with problems)
🌙 ramps down when effort stops and safety cues appear
For many neurodivergent adults, a few things are different:
🔥 More things are experienced as demanding or threatening
📡 Your system is scanning and processing more sensory and social data
⏳ Stressors don’t switch off just because the task ended (your brain keeps re-running them)
That means:
- the “go mode” part is activated more often and for longer
- the “rest mode” part doesn’t get clear signals that it’s safe to take over
You end up with:
💭 a brain that keeps scanning
💢 a body that stays tense
🪫 energy reserves that quietly drain in the background
🎧 Why ND Brains Are So Prone to Wired-and-Tired States
Autism, ADHD and AuDHD each add their own ingredients to the mix.
🌈 Sensory Processing Differences
If your sensory system is more sensitive or less filtered, an average day may involve:
🔊 More noise layers (voices, traffic, appliances, movement)
💡 Harsher or more complex visual environments (screens, clutter, lights)
🧥 Continuous low-level stress from clothing, temperature, textures or smells
Your nervous system is doing extra work just to be in the same spaces as everyone else, often without visible signs until you hit your personal limit.
That continuous sensory “busy-ness” keeps your alert system partly lit, even when you’re sitting still.
🧮 Executive Function Load
Executive function (planning, prioritising, switching tasks, remembering, making decisions) is often a high-demand area in ADHD, autism and AuDHD.
In a typical ND day, your brain may be:
📋 tracking multiple unfinished tasks and responsibilities
📎 holding mental to-do lists because external tools are hard to maintain
🔁 constantly shifting between tasks and roles with very little buffer time
🧯 putting out small fires — messages, reminders, small emergencies, forgotten tasks
Even when nothing huge is happening, there can be a steady background sense of:
💭 “I’m behind.”
💭 “There’s something I’m forgetting.”
💭 “I can’t drop my guard or things will fall apart.”
This keeps your threat system slightly on, which blocks deep rest.
💥 Emotional Load and Masking
Many ND adults carry long-term emotional load from:
🧱 masking and camouflaging in social or work settings
🧩 trying to appear “fine” while overloaded
🧊 managing rejection sensitivity, criticism or misunderstandings
📜 living with a long history of being told they’re too much or not enough
That can create a chronic internal narrative of:
💭 “Don’t relax, you might mess up.”
💭 “If you drop the ball, people will be disappointed.”
💭 “If you stop performing, they’ll see the ‘real you’.”
The result is a nervous system that doesn’t fully trust rest. It treats downtime as risky instead of safe.
🔁 The ND Wired-and-Tired Cycle
Over time, these factors can turn into a repeating pattern.
A common cycle looks like this:
🌅 1. Start the day already under-slept or unrested.
You wake up with low capacity but high demands (work, caregiving, admin).
🏃 2. Push through the day on “alert mode”.
You use stress, deadlines, masking, or caffeine to keep going. You ignore fatigue signals.
🌊 3. Sensory and cognitive overload build quietly.
Noise, social interaction, decisions and problems stack up. You rarely get proper breaks.
🌙 4. Evening arrives; your body is tired but your system is still revved.
You finally stop — but your brain speeds up. Thoughts, “what if” scenarios, planning, and replaying the day all intensify.
📱 5. You use stimulation to avoid raw discomfort.
Scrolling, games, shows, chatting, snacking, late-night research — anything that keeps your mind busy enough to not feel the full weight of the day.
⏰ 6. Sleep is delayed or shallow.
You go to bed late, or you fall asleep but don’t reach deep rest. You might wake up during the night or wake unrefreshed.
🔁 7. Next day starts with even lower capacity.
And the cycle repeats, often with more burnout and less flexibility each time.
This isn’t “bad habits”. It’s a nervous system survival loop that started out adaptive and then became chronic.
🧭 How to Tell When You’re in a Wired-and-Tired State
It can help to recognise this state earlier, before you reach total collapse.
You might be wired and tired if:
🪙 Your thoughts feel fast but unproductive (loops, not solutions)
🧊 Your body feels both tense and heavy at the same time
📱 You bounce between tabs, apps, or tasks without really engaging
🌫 You feel detached, numb or “not fully here” but also unable to rest
💬 You know you need a break, but the idea of stopping makes you anxious or restless
🕰 You delay bedtime even though you’re clearly exhausted
Seeing this as a specific state of your nervous system — not your personality — makes it easier to respond with targeted support instead of criticism.
🌱 Phase 1 – Calming a Wired System Without Demanding Full Rest
If your body is wired, telling yourself “just relax” rarely works. You usually need steps in between.
Think of it as moving from:
🚨 red alert → 🟠 amber → 🟢 green
not straight from red to green.
🌬 Use Small, Concrete Down-Shifts
Tiny physical actions can send “we are safe enough” signals to your nervous system.
You might try:
🧊 Cool or warm sensations
🧊 Holding something cool (glass of water, cold pack, cool spoon)
🧊 Or a warm drink or heat pack if your body tends to freeze when stressed
🪑 Supportive posture
🪑 Sitting with your back against a wall, feet flat on the floor
🪑 Leaning into cushions or a weighted blanket
👂 Gentle rhythmic input
👂 Rocking slightly, swaying, or tapping your foot in a steady rhythm
👂 Listening to predictable, low-intensity sounds (rain, brown noise, soft instrumental music)
These don’t “solve” the problem, but they lower your level of activation just enough that other things become possible.
🧵 Keep Your Brain Slightly Occupied (But Not Overloaded)
Going straight from overstimulation to silence can backfire. A middle step is often more realistic.
Options:
📖 Low-stakes reading (familiar fiction, gentle non-fiction, fanfic, comfort topics)
🎧 Audiobooks, podcasts, or YouTube channels that feel safe and predictable
🎨 Simple crafts or fidgets where your hands move and your thoughts can slow down
The key is:
- no high stakes,
- no intense plot or conflict,
- nothing that pulls you into research rabbit holes.
You’re giving your mind something to “hold” while your body catches up.
🧃 Phase 2 – Supporting Tiredness (Body) and Overload (Brain) Separately
“Rest” is often treated as one thing, but wired-and-tired usually needs two kinds of support:
- physical repair
- cognitive + sensory relief
🛏 Gentle Body Rest (Without Demanding Sleep)
You can rest your body even if your mind is busy.
For example:
🌙 Lie down or recline with your eyes half-closed, no pressure to sleep
🧣 Use a blanket or weighted item in a position that feels secure and not exposed
🧍 Alternate very small movements (stretching fingers, rolling shoulders) with stillness
You can even pair this with light mental occupation (audio, gentle show) while your muscles and joints get a break.
🌫 Mental and Sensory Decompression
Your brain also needs time without new demands.
Helpful tools:
🌑 Dim the lights or use lamps instead of overhead lighting
🧼 Reduce visual clutter in your immediate field of view (table, bedside, desk)
🔕 Turn off non-essential notifications for a set window (for example, 30–60 minutes)
You’re telling your nervous system:
💭 “Nothing urgent is coming in right now. It’s allowed to downshift a bit.”
📆 Phase 3 – Designing “Wired-and-Tired Aware” Days
Over the longer term, the goal isn’t to never get wired and tired (that’s unrealistic), but to spend less time stuck there and reduce the depth of each episode.
🧭 Build Very Small Regulation Moments into the Day
Instead of waiting until you’re completely fried, add micro-breaks:
☕ 1–3 minute pauses between tasks where you look away from screens
🚶 Short transitions where you stand up, move, drink water before the next block
🕯 Tiny sensory resets (stretch + deep exhale + gaze at something neutral)
These moments don’t fix everything, but they slow the build-up of overload.
🧱 Reduce One Source of “Quiet Stress”
You might not be able to change your job, family, or housing right now. But many people have at least one removable source of constant micro-stress.
Examples:
📱 Muting or leaving one high-drama group chat
📧 Unsubscribing from a handful of marketing emails that constantly nag your brain
📆 Dropping a non-essential obligation that always costs more energy than it’s worth
Every small reduction in background load creates a little more capacity for your system to self-regulate.
📚 Reframing Rest as Maintenance, Not Reward
If rest only feels “allowed” after everything is done, you will almost never feel safe resting.
A more realistic frame:
💭 “Rest is something my nervous system needs to function at all, not a prize I earn for performing well.”
That might mean:
🧃 Scheduling short rest blocks before busy periods
🛋 Using “maintenance rest” daily (even 10–15 minutes) rather than waiting for collapse
📌 Treating these blocks as appointments with your nervous system, not optional extras
🛡 ND-Friendly Strategies for Evenings and Bedtime
Evenings are often peak wired-and-tired time. A few small design choices can help.
🕯 Create a “Landing Strip”, Not a Brick Wall
Instead of:
💭 “At 22:30 I must be in bed doing nothing.”
Try having a 30–60 minute landing strip:
🌆 First part: light, engaging but low-stakes activity (familiar show, audio, cosy game)
🌘 Second part: more offline or reduced-input (dimmer lights, calmer sounds, less interaction)
🌙 Last part: bed-only activities (audio, light reading, comfortable stimming, or simply lying there)
You’re guiding your nervous system down in stages instead of slamming on the brakes.
🙃 Pre-Empt the Late-Night “Sudden Projects”
ND brains often throw up urgent-seeming ideas at night:
💡 “I should research this right now.”
💡 “I need to plan my whole life for next year.”
You can respond by:
📝 Keeping a small “night thoughts” note page or notebook
🧠 Writing down the idea, then telling yourself: “It is captured; I don’t have to solve it at 23:47.”
This satisfies the brain’s need to not lose the thought, without using up all your remaining energy on a midnight deep dive.
🧷 What This Isn’t: You Being Broken or Bad at Rest
It can be tempting to see wired-and-tired as evidence that:
❌ you’re “addicted to your phone”
❌ you “don’t know how to relax”
❌ you’re “bad at adulting”
From a nervous-system perspective, though, the picture is different:
- your brain and body have been running at a level that isn’t sustainable
- your sensory and emotional inputs are higher than the average person’s
- your system has learned to fear full stillness because that’s when backlog hits hardest
In that context, it’s logical that your system clings to:
📱 stimulation that keeps feelings and thoughts at bay
🧱 constant readiness, because life has often been unpredictable and unforgiving
🧯 old survival strategies that once kept you going
None of that makes you weak. It makes you someone whose nervous system has been doing its best in conditions it was never designed for.
🌈 Bringing It Together
“Wired and tired” is not a vague mood. It’s a recognizable, understandable nervous-system state where:
⚡ your alert system is still switched on
🪫 your energy is already depleted
🌊 your sensory, emotional and cognitive loads are all higher than ideal
You can’t fix it overnight — and you don’t have to.
What you can do is:
🌱 recognise when you’re in that state
🌱 use small, body-based and sensory-based downshifts rather than shouting at yourself to “relax”
🌱 separate physical rest from mental rest so both get some attention
🌱 design days and evenings that include regulation on purpose, not only after you crash
Every time you help your nervous system move one step down from red to amber, you’re not just surviving the day. You’re also teaching your system that:
💭 “It’s possible to slow down a little without losing everything.”
