Understanding sensory overload: practical ways to soothe a busy brain

If bright lights, background noise, strong smells, or busy places leave you feeling snappy, foggy, or completely wiped out — you’re not being “too sensitive”. Your nervous system is doing its best to cope with a lot of input all at once.

Sensory overload is incredibly common for autistic people, ADHDers, and AuDHDers — and it can also show up during anxiety, burnout, trauma stress, menopause, pregnancy, grief, or simply when life is full-on. This post is here to help you understand what sensory overload is, how it shows up, and (most importantly) some gentle, practical ways to support yourself.

As always: take what fits, leave what doesn’t.

What is sensory overload?

Sensory overload happens when your brain takes in more information than it can comfortably process in that moment. It’s not just “disliking” noise or bright lights — it’s your system hitting capacity.

Think of it like having too many tabs open. Eventually, something freezes.

Overload can be triggered by things like:

• bright lighting (especially fluorescent lights)

• loud or layered noise (music + chatter + traffic)

• crowded spaces and unpredictable movement

• strong smells (perfume, cleaning products, food courts)

• certain textures in clothing or food

• temperature changes

• too much social interaction (especially masking)

• being rushed, interrupted, or having lots of decisions to make

And the tricky part? It often builds up over time. What you can tolerate on a calm day might feel unbearable when you’re tired, stressed, hungry, or already holding too much.

How sensory overload can look (it’s not always obvious)

Sometimes overload looks like panic — but often it’s subtler.

You might notice:

• irritation, tearfulness, or feeling “on edge”

• a sudden urge to escape or shut down

• difficulty speaking or finding words

• feeling disconnected, numb, or spaced out

• headaches, nausea, dizziness, tight chest

• needing silence or darkness

• snapping at people (even when you don’t want to)

• feeling exhausted afterwards, sometimes for hours or days

If this resonates, it doesn’t mean you’re failing. It means your nervous system is signalling: this is too much, too fast, too loud, too bright.

Why overload feels so intense

When your senses are overwhelmed, your brain often shifts into threat mode — fight, flight, freeze, or fawn. That’s why overload can feel urgent and emotional, even if you can logically tell yourself, “I’m safe.”

It’s not a mindset problem. It’s a body-and-brain response.

The goal isn’t to “toughen up”. The goal is to learn what helps your system come back into safety.

Practical ways to soothe sensory overload

1) Reduce input (even slightly)

When you’re overloaded, your brain doesn’t need more strategies — it needs less stimulation.

Try:

• stepping outside for a minute

• turning your body away from the noise/light

• lowering brightness on your phone

• moving to the edge of the room (less movement around you)

• swapping “busy” headphones for noise-reducing ones (or vice versa)

Even a 10% reduction can help.

2) Use “sensory tools” like you would a coat in winter

Support isn’t a luxury — it’s practical.

Helpful options:

• noise-reducing headphones / earplugs

• sunglasses / cap / brimmed hat

• a soft scarf or hoodie (comfort texture)

• fidget or tactile object

• chewing gum or mints (oral input can be regulating)

• a warm drink or cold water (temperature can ground you)

The best tools are the ones you’ll actually use without having to negotiate with yourself.

3) Try a quick reset for your nervous system

If your body is in threat mode, grounding can help signal safety.

A simple one:

• breathe in for 4

• breathe out for 8

• repeat 5 times

Or:

• press your feet into the floor

• notice 3 things you can see

• unclench jaw + drop shoulders

• gently squeeze your hands together (pressure can help)

You’re not trying to “get rid” of overload — you’re helping your system ride the wave.

4) Make a “recovery routine” for afterwards

Many people feel shame after overload (“Why can’t I cope?”). But recovery is a normal part of having a sensitive nervous system.

After a high-input situation, your brain may need:

• quiet, low light, minimal conversation

• a predictable safe activity (same show, same music, same snack)

• gentle movement (walk, stretching, rocking)

• pressure (blanket, cushion, leaning into a wall)

• time alone without explaining yourself

Recovery isn’t dramatic. It’s maintenance.

5) Spot your early warning signs

Overload is easier to manage when you catch it early.

Your signs might be:

• everything feels “too loud”

• you start rushing

• you feel suddenly hot, itchy, or tense

• you can’t concentrate on speech

• you want to cry or explode

If you notice the first signs, try asking:“What would help me feel 5% more comfortable right now?”

Small adjustments early can prevent a crash later.

6) Plan for the environments that drain you

This isn’t about controlling your whole life — it’s about reducing avoidable stress.

You might:

• go to shops at quieter times

• take breaks between errands (not back-to-back)

• sit near exits in cafés/venues

• choose one social thing per day (or per weekend)

• build “buffer time” before and after appointments

A busy brain often needs more transitions than other people realise.

7) Use scripts to protect your energy

When you’re overwhelmed, words can disappear. Having a few phrases ready can help.

• “I need a quick breather — I’ll be back in a moment.”

• “I’m getting overloaded, I’m going to step outside.”

• “I can’t process this right now — can we pause?”

You don’t have to justify your nervous system.

A gentle reminder about shame

If you’ve spent years masking, pushing through, and forcing yourself to “act normal”, it makes sense that you might feel guilty for needing accommodations.

Sensory overwhelm isn’t a character flaw. It’s a nervous system response — and you deserve support, not self-criticism.

How therapy can help

In neurodiversity-affirming, trauma-informed counselling, we can explore:

• your sensory profile and triggers (without judgement)

• how anxiety/burnout/masking interacts with overload

• ways to set boundaries that actually feel doable

• self-compassion (especially after shutdowns or meltdowns)

• practical tools tailored to how your brain works

I offer neurodiversity-affirming therapy in Chorley and online, supporting autistic, ADHD and AuDHD adults with anxiety, burnout, masking, and sensory overwhelm.

If you’d like support, you’re welcome to get in touch — you don’t have to navigate a busy brain on your own.
