Sensory input is coming at us constantly. Whether we are in a quiet room by ourselves or at a busy birthday party, sensory experiences are shaping how we perceive the world around us. Sensory overload can happen to all of us, but for children with sensory processing issues, it can be overwhelming. They may not have the tools and coping skills to handle all the sensory information their bodies are processing. 
What is sensory overload?
Sensory overload occurs when the body is unable to process, organize, and respond to all the incoming sensory input. Although this can happen to anyone, it is more common in those who have Sensory Processing Disorder (SPD) or sensory issues.
Technology and our fast paced society has led to us being bombarded with more and more sensory stimuli. It is no wonder that our brains and nervous systems are sometimes overloaded.
Picture this:
It’s public swim time at the local indoor pool. There are the sounds of kids screaming, babies crying, parents calling out to get their child’s attention, music coming over the speakers, the whir of the pumps, the constant flow of the waterslide, the drip of the waterfall, and splashing water.
You see bright overhead lights, a row of red and yellow life jackets hanging on the wall, people everywhere, pool toys and flotation devices covering the surface of the water, diving boards, a swinging rope, spinning ceiling fans, and there’s even a woman practising kickboxing on a yoga mat on the pool deck.
There is the feel of the pressure of water around you, water suddenly being splashed into your face as someone kicks nearby, the warmth of the hot tub and sauna contrasted with the cold of the salt water children’s wading pool.
You pick up on a mixture of smells as the chlorine of the adult pool and the salt water of the children’s pool mix with everyone’s shampoos and body washes and perfumes. There’s the taste of salt or chlorine as you come up sputtering. There’s the feeling of the movement through the water or the burn of the waterslide on your back and the feel of the air on your face as you quickly soar through the air off the high diving board before plunging into the water below.
This doesn’t even take into consideration the crowded change rooms or lobby. It’s easy to see how anyone could experience sensory overload on a trip to the swimming pool!
Why is it important to recognize the signs of sensory overload?
By catching the signs of sensory overload early, you can help your child to self-regulate and possibly prevent a sensory meltdown or having your child go into fight, flight, or freeze mode. Sensory overload is not the same as a sensory meltdown, but it can be the precursor to one.
When children have sensory processing challenges, it makes them more susceptible to sensory overload. They may not be able to recognize the signs themselves until they are slowly taught to do so. This is why it is important for their parents or teachers to be on the lookout for clues that indicate that sensory overload is happening.
It is also important to talk about those signs with the child to help them recognize them in themselves. This is something that is usually best done later when the child is calm and no longer showing signs of sensory overload.
What are the signs of sensory processing overload in children?
- appears to have a higher level of activity (over excited) or sensitivity than normal during or following an activity
- becomes increasingly distracted, disoriented, or confused
- may feel nauseous and/or vomit
- sudden paleness or flushed, sweaty, or clammy skin
- rapid breathing or slower shallow breathing
- decreased or increased muscle tone
- tremors
- glazed-over look in the eyes or signs of a possible seizure
- drowsiness/fatigue
- sleeplessness
- irritability and/or angry outbursts
- “shuts down” and refuses to participate in an activity
- makes poor eye contact
- covers eyes around bright lights
- covers ears to avoid loud sounds or voices
- avoids being touched or touching others
- constantly changing a task, never finishing
- fidgeting and restlessness

Preventing sensory overload:
- Monitor the environment. Be on the lookout for things that may be giving too much sensory input.
- Reduce the visual and auditory clutter in your home, especially in rooms the child spends the most time.
- Avoid places and situations that will have too much stimulus.
- When those situations can’t be avoided, provide tools such as noise reducing headphones to reduce sensory input.
- Work with a qualified Occupational Therapist (OT).
- Offer regular sensory breaks throughout the day.
- Take extra time and give warnings to help the child prepare for any transition times.
- Maintain a predictable schedule and routine.
- Use calming strategies and breathing techniques.
My friend Heather at Growing Hands-On Kids has written a great article detailing sensory overload in the classroom. It’s a wonderful tool to help teachers and parents.

Some degree of anxiety is normal for all children. When anxiety begins to interfere with your child’s daily activities, attending school or social situations, or prohibits them from doing what other children their age are doing, it is time to consult a professional.
