**Short answer:** Sensory overload is when sounds, lights, smells, textures or crowds become more than a child's brain can handle, and it can lead to a meltdown or shutdown. Many autistic kids feel some senses much more strongly, or less strongly, than others. Knowing your child's triggers, planning breaks, and tools like headphones can prevent a lot of overload.

**Key takeaways**
- Sensory overload happens when **noise, light, touch or crowds** become **too much**.
- Many autistic kids feel senses **more strongly**, or **less strongly**, than others.
- Overload can lead to a **meltdown or shutdown**.
- **Know the triggers, plan breaks** and keep a **calm-down kit** ready.

## What is sensory overload?

Our brains filter a constant stream of sounds, sights, smells and feelings. Many autistic kids experience some of these much more intensely. Differences in how a person reacts to sensory input are part of how autism is diagnosed.[1]

Sensory overload happens when there's more input than a child can process. A buzzing light, a scratchy tag and a noisy room might each be bearable alone, but together they're too much.

## What are the signs of sensory overload?

Every child is different, but common signs include:[2]

- Covering ears or eyes
- Trying to leave, hide or crawl under things
- Getting louder, more upset, or suddenly very quiet
- Rocking, flapping or other stims increasing
- Refusing to go into a place, or melting down once there

| Sense | Can be too much | Some kids seek |
| --- | --- | --- |
| Sound | Hand dryers, crowds, sirens, vacuums | Loud music, making noise |
| Sight | Bright or flickering lights, busy rooms | Spinning or shiny things |
| Touch | Tags, seams, hair brushing, messy hands | Tight hugs, heavy blankets |
| Taste and smell | Strong smells, mixed textures | Crunchy or spicy food |
| Movement | Swings, escalators | Jumping, spinning, crashing |

## What helps during sensory overload?

1. **Reduce input**: lower your voice, dim lights, move somewhere quieter.
2. **Talk less**: a few calm words are easier than questions.
3. **Offer the calm-down kit**: headphones, sunglasses, a comfort item.
4. **Give time**: recovery can take a while. Don't rush back.

**Pack a calm-down kit.** Keep headphones, a favorite fidget, a snack and a comfort item in a small bag for outings. A calm-down card shows your
  child what they can choose.

## How can I prevent overload?

**Try:**
- Noise-reducing headphones in loud places
- Shopping or visiting at quiet times
- Tagless, soft clothing your child chooses
- A picture schedule so outings are predictable
- Breaks built into busy days

**Skip:**
- Forcing your child to "get used to it"
- Back-to-back busy outings
- Leaving without a plan to take a break

**An OT can help.** Occupational therapists can assess sensory needs and suggest ideas for home and school. See [What does an occupational
  therapist do?](https://theautismkit.com/guides/occupational-therapy-for-autism)
  [3]

**Talk to your pediatrician if....** sensory reactions stop your child from eating enough, sleeping, getting medical care or going to school. These are
  worth getting help with.

## Common questions

### Is sensory overload the same as a meltdown?

Not exactly. Overload is the feeling of too much input. A meltdown can be what happens when overload, stress or tiredness builds past what a child can cope with.

### Should my child wear noise-canceling headphones all the time?

Headphones are a great tool for loud places. Many families use them for specific settings, and also build in quiet time so a child isn't overloaded all day.

### What is sensory seeking?

Some kids need more input: crashing, spinning, chewing or touching everything. It's the other side of sensory differences, and an occupational therapist can suggest safe ways to meet it.
