Why Am I So Sensitive to Noise, Light and Smells?
Everyday sounds, bright light, smells, textures or busy places can sometimes feel much stronger or more difficult than they seem to other people.
- People can experience sensory input very differently.
- Sound, light, smell, touch, taste and movement can all become difficult.
- Several sensory demands at once can add up to overload.
- Sensory tolerance may not feel the same every day.
- Reducing unnecessary sensory load can make everyday life more manageable.
The television is on.
Someone is talking.
A fan is humming.
The lights feel too bright and someone nearby is wearing perfume.
To another person, none of these things may seem particularly important.
To you, they may all be demanding attention at once.
People differ in how strongly they notice, process and respond to sensory information.
What can sensory sensitivity feel like?
Sensory sensitivity is not always simply noticing something more.
The experience may feel:
- distracting
- irritating
- uncomfortable
- overwhelming
- exhausting
- stressful
- or sometimes physically painful
Different people may also be sensitive to very different things.
Sound
Voices, appliances, traffic, music, chewing, alarms or several sounds happening together.
Light & visual input
Bright lighting, glare, flashing screens, movement, clutter or visually busy environments.
Smell
Perfume, cleaning products, food smells, smoke or other strong odours.
Touch & texture
Clothing, labels, fabrics, unexpected touch, food textures or temperature.
Why does it feel stronger to me?
The brain is constantly receiving information from the senses.
Much of the time, we can focus on what matters and let other information sit in the background.
For some people, certain sensory information is much harder to ignore or feels much more intense.
That means something another person barely notices may require a significant amount of your attention and capacity.
You are trying to have a conversation in a café.
At the same time there is music, coffee equipment, dishes clattering, people talking, movement around you and strong food smells.
You are not only having a conversation.
Your brain is also managing the environment.
Sensory load uses capacity
Processing sound, light, smells, movement and other sensory input can take energy and attention. A busy environment can therefore make thinking, communicating and coping harder too.
What is sensory overload?
Sometimes the amount of sensory information becomes more than you can comfortably process at that moment.
You may notice:
- irritability
- a strong need to leave
- difficulty thinking
- difficulty talking
- feeling panicky or distressed
- needing things to stop
- shutting down
- becoming much less able to cope with other demands
It may not be one particular sound, light or smell. Sometimes several smaller demands have simply added up.
Why can I tolerate it one day but not another?
Sensory tolerance can feel different depending on what else your body and brain are managing.
For example, sensory input may be harder to tolerate when you are:
- tired
- in pain
- having a migraine
- unwell
- stressed
- hungry
- already overloaded
- trying to concentrate
- recovering from a demanding day
This does not necessarily mean the environment changed.
Your available capacity may have changed.
A quick sensory-load check
What can help?
The goal does not always have to be becoming able to tolerate every environment.
Sometimes the more useful approach is reducing unnecessary load.
Depending on the situation, that might mean:
- moving somewhere quieter
- turning down or switching off background sound
- reducing glare or bright lighting
- using sunglasses or a hat where appropriate
- using ear protection selectively
- avoiding strongly scented products where possible
- choosing quieter times to shop or attend appointments
- taking breaks from busy environments
- reducing other demands at the same time
- allowing recovery afterwards
You do not necessarily need to change everything. Reducing one or two major sensory demands may make the whole situation more manageable.
Why does sensory overload make it hard to think or talk?
Thinking and communication also use capacity.
When much of your attention is being used to process or cope with the environment, there may be less available for:
- finding words
- following a conversation
- remembering information
- making decisions
- planning what to do next
- regulating emotions
This is one reason a quieter environment can sometimes make communication easier.
When is it worth getting sensory sensitivity checked?
Sensory sensitivity can have many different contexts.
It is worth discussing with a health professional when it is:
- new or suddenly different
- severe or painful
- getting noticeably worse
- affecting hearing, vision or other sensory function
- significantly affecting everyday life
For example, everyday sounds that seem unusually loud or painful can sometimes be related to hearing conditions such as hyperacusis and may benefit from assessment.
The environment matters
When your sensory system is already working hard, making the environment quieter, softer or less demanding can sometimes free up capacity for everything else.
A simple thing to remember
Instead of only asking:
“Why am I reacting so much?”
Try asking:
“What is my sensory system dealing with right now?”
That may make it easier to notice what is adding to the load and what could be changed.
