When the world feels louder, brighter, and harder to filter
There is a particular kind of exhaustion that comes from migraine sensory sensitivity.
The overhead lights feel sharper than they should. A normal conversation sounds too loud. Someone’s perfume lingers in the air like a warning signal. The grocery store feels impossible. The hum of an appliance, the flicker of a screen, the smell of lunch from another room — suddenly, everything has weight.
From the outside, it can look like “being sensitive.”
From the inside, it can feel like your brain has lost the ability to turn the volume down.
At this year’s Migraine World Summit, Dr. Amaal Starling explained that migraine involves abnormal sensory processing in the brain — not just abnormal pain processing. She described migraine as a genetic neurologic disease in which the brain processes sensations differently, including light, sound, smell, touch, motion, temperature, body position, internal body signals, and pain.
That idea matters.
Because migraine sensory sensitivity is not a personality trait. It is not weakness. It is not dramatic.
It is one of the ways migraine can affect how the nervous system receives, filters, and responds to the world.

What migraine sensory sensitivity actually means
Migraine sensory sensitivity means the brain may respond more intensely to sensory input than expected.
That input can come from outside the body, such as:
- light
- sound
- smell
- touch
- motion
- temperature changes
It can also come from inside the body, such as hunger, thirst, pain, dizziness, or changes in body position.
Dr. Starling explained that sensory processing is not limited to the five senses most people learned about in school. It also includes vestibular input, which helps the brain understand motion; proprioception, which helps the brain know where the body is in space; interoception, which involves internal signals like hunger, thirst, and temperature; and nociception, which involves pain perception.
That is why migraine can feel so much bigger than light sensitivity alone.
It can involve the entire sensory system.
And once you understand that, the experience starts to feel less random.
Why migraine sensory sensitivity can affect more than the five senses
Most people recognize that migraine can involve sensitivity to light and sound. In fact, Mayo Clinic lists extreme sensitivity to light and sound among common migraine symptoms. (Mayo Clinic)
However, migraine sensory sensitivity can go beyond that.
It may include:
- sensitivity to smell
- sensitivity to touch
- motion sensitivity
- dizziness or vertigo-like sensations
- temperature discomfort
- skin sensitivity
- heightened awareness of internal body signals
Dr. Starling described migraine as abnormal processing of “all of the senses” — not just pain, but light, sound, smell, motion, and more.
Dr. Jessica Ailani made a similar point in her summit interview. She explained that migraine can involve the brain and peripheral nervous system, which means symptoms can show up through vision, hearing, smell, sensation, temperature regulation, focus, and other body systems.
In other words, when migraine affects sensory processing, the whole environment can feel different.
Not because the world changed.
Because the way your brain is processing the world has changed.
Migraine light sensitivity, sound sensitivity, and smell sensitivity
For many people, the most recognizable forms of migraine sensory sensitivity are light, sound, and smell sensitivity.
Light may feel harsh, flickering, piercing, or impossible to ignore. The American Migraine Foundation describes photophobia as abnormal and extreme light sensitivity and notes that it is a common symptom of migraine. (American Migraine Foundation)
Sound can feel intrusive even when it is ordinary. Background noise may become difficult to filter. A normal room can suddenly feel too busy.
Smell sensitivity can be especially frustrating because scent is hard to escape. Food, fragrance, cleaning products, candles, smoke, or chemicals may become overwhelming. In Dr. Ailani’s interview, she described patients who are so smell-sensitive that they can detect what is cooking several rooms away or notice smells on someone’s clothing.
That heightened awareness can feel strange.
It can also be deeply disruptive.
Because when light, sound, and smell all become more intense at once, the brain has less room to process anything else.

Why ordinary sensations can feel painful or intrusive
One of the clearest scientific explanations Dr. Starling gave is something called a habituation deficit.
In simple terms, habituation is the brain’s ability to get used to repeated input.
For example, someone without migraine might walk into a room with a soft hum or a flickering light and notice it at first. After a while, the brain filters it out.
But in people with migraine, that filtering process may not work as smoothly. Dr. Starling explained that repetitive stimulation can continue to feel “fresh,” intrusive, and potentially painful instead of fading into the background.
That helps explain why everyday environments can become exhausting.
It is not simply that the light is bright.
It is that the brain may keep registering the light as new input.
It is not simply that the sound exists.
It is that the brain may struggle to dismiss it.
This is one reason migraine sensory sensitivity can feel like being trapped in a world with no mute button.
Migraine sensory sensitivity can feel like a “superpower”
There is a gentler way to understand this, too.
Both Dr. Starling and Dr. Ailani touched on the idea that people with migraine may have a kind of heightened awareness of their environment. Dr. Starling described this through an evolutionary lens: in another setting, being hyperresponsive to weather, light, sound, smell, or danger may have helped people survive.
Dr. Ailani similarly described heightened sound and smell sensitivity as almost “superhuman” in some patients, while also acknowledging that this can make daily life difficult.
That framing can be validating.
Because for many people, migraine sensory sensitivity does feel like an unwanted superpower.
You notice the hum no one else hears. You smell the candle before anyone else reacts. You feel the flicker in the light when everyone else says the room is fine.
That does not mean you are imagining it.
It may mean your brain is detecting more — and having a harder time filtering what it detects.
Migraine sensory overload and the fight-or-flight response
When sensory input becomes too much, the body can shift into a more protective state.
Dr. Starling explained that sensory overload can increase hypervigilance and push the nervous system toward fight-or-flight mode. In that state, the body becomes even more responsive to light, sound, smell, pain, and other stimulation.
That loop matters.
Because once your system becomes overloaded, everything can feel louder, brighter, closer, and harder to manage.
This is why migraine sensory overload is not just discomfort. It can feel like the nervous system is on alert.
And when that happens, support often needs to be simple.
Not complicated.
Not demanding.
Not another task to figure out.
Just a way to reduce input, create steadiness, and give your system less to fight against.

Touch sensitivity, allodynia, and central sensitization
For some people, migraine sensory sensitivity also includes touch.
Clothing may feel irritating. A ponytail may feel painful. Resting your head on a pillow may feel uncomfortable. Even normal touch can feel too intense.
This is often discussed through the lens of allodynia, which means a normally non-painful stimulus becomes painful. Dr. Starling described allodynia as a biomarker for central sensitization and noted that it can happen during attacks or even between attacks in some people with migraine.
Dr. Ailani also discussed skin sensitivity and pain outside the head, noting that some people feel unusually sensitive before, during, or after an attack.
That does not mean every sensation should automatically be assumed to be migraine. But it does mean touch sensitivity can be part of the broader migraine picture.
This is where language matters.
When someone says, “My skin hurts,” they may be describing a real nervous-system experience.
Motion sensitivity and vestibular symptoms
Migraine sensory sensitivity can also involve motion.
Dr. Starling described vestibular input as one of the body’s sensory systems. It helps the brain understand whether the body is moving, whether the environment is moving, and where you are in space.
When that processing is disrupted, people may feel dizzy, off-balance, motion-sensitive, or internally unstable.
Some people meet criteria for vestibular migraine. Others may not, but still experience dizziness or motion sensitivity as part of their migraine pattern. Dr. Starling explained that migraine is not only about pain, but abnormal processing of light, sound, smell, motion, and other senses.
If dizziness or balance symptoms are new, severe, changing, or concerning, they are worth discussing with a healthcare professional. Migraine can explain many symptoms, but it should not become a blanket explanation for everything.
Is sensory sensitivity the same as a migraine trigger?
Not always.
This is one of the most important distinctions in migraine education.
Sometimes light, sound, smell, or motion may contribute to sensory load. However, those sensitivities can also be early signs that a migraine process has already started.
Dr. Ailani explained this clearly when discussing light sensitivity. What feels like “the lights triggered my migraine” may sometimes be the brain already becoming hypersensitive as part of prodrome, the early phase of an attack.
That changes the question.
Instead of only asking, “What triggered this?”
You can also ask, “Was my nervous system already changing?”
That shift can make patterns easier to understand.
It can also reduce the pressure to avoid everything, all the time.
What helps when migraine sensory sensitivity hits
When migraine sensory sensitivity is active, the goal is not to eliminate the world.
The goal is to reduce overload and create more stability.
Dr. Starling explained that stability is one of the most useful principles for people managing sensory input. When certain factors, such as weather, cannot be controlled, people may still be able to support steadiness through sleep, eating patterns, hydration, movement, and stress-coping skills.
That might look like:
- softening harsh light
- reducing screen brightness
- stepping away from strong smells
- lowering background noise
- choosing calmer textures or clothing
- using paced breathing or grounding
- keeping hydration and meals steady
- creating a predictable sensory routine
The American Migraine Foundation also notes that light sensitivity is common in migraine and that adjusting the environment — such as reducing harsh lighting — may help make spaces more manageable. (American Migraine Foundation)
At Aevere, this is where sensory-safe support becomes important.
When your system is overloaded, support should be easy to reach for. It should not require a complicated plan. It should help make the moment feel more manageable.
That may include tools like FL-41 light-filtering glasses, calming environmental shifts, or a simple routine from the Aevere Ritual System.
Why avoiding every sensation can sometimes backfire
Avoidance makes sense when something hurts.
If light feels painful, of course you want less light. If sound feels unbearable, of course you want quiet. If motion makes you dizzy, of course you want stillness.
However, Dr. Starling explained that with light sensitivity, avoiding light more and more may sometimes increase the sensory “gain” on those pathways, making the brain even more sensitive over time. She described the importance of gradual desensitization in some patients, guided by appropriate clinical support.
This is an important point.
It does not mean you should force yourself into overwhelming environments.
It means the goal is not always total avoidance.
Often, the goal is thoughtful pacing.
Less overwhelm.
More stability.
Gentle re-entry when appropriate.
Support that meets your system where it is.
The Aevere perspective on migraine sensory sensitivity
At Aevere, we believe migraine sensory sensitivity deserves more thoughtful support.
Not because it is rare.
Because it is common, disruptive, and often misunderstood.
People with migraine are constantly asked to function in environments that were not designed for sensitive nervous systems: harsh lighting, loud spaces, strong fragrance, screens, open offices, busy stores, unpredictable routines.
So the answer cannot simply be, “Try harder.”
The answer has to be better design.
Better rituals.
Better tools.
Better education.
Better ways to recognize when the nervous system is already under load.
That is why Aevere is built around sensory-safe support: not to promise control over migraine, but to help make hard moments easier to navigate.

When to talk to a provider about sensory symptoms
Sensory symptoms are common in migraine, but they are still worth discussing with your clinician, especially if they are new, intense, changing, or affecting daily life.
Dr. Ailani emphasized that unusual symptoms should be brought to a healthcare professional, particularly when symptoms are new or different from your usual pattern. She also noted that certain symptoms, such as new weakness, speech difficulty, chest pain, severe dizziness, or major changes in vision, deserve urgent evaluation.
That guidance matters because migraine can explain many things.
But it should not be used to ignore symptoms that need attention.
A good rule of thumb is this:
If it is familiar and consistent, track it.
If it is new, severe, or different, ask.
Final thought
If light feels sharper, sound feels louder, smell feels stronger, or touch feels more intense during migraine, you are not being difficult.
Your nervous system may simply be processing the world differently.
That can be exhausting.
But it can also be understood.
And once migraine sensory sensitivity becomes easier to name, it becomes easier to support.
Not perfectly.
Not all at once.
But with more clarity, more compassion, and less self-blame.
FAQ: Migraine Sensory Sensitivity
What is migraine sensory sensitivity?
Migraine sensory sensitivity is when the brain responds more intensely to sensory input such as light, sound, smell, touch, motion, temperature, or pain. It can happen before, during, after, or between migraine attacks.
Why does migraine make light, sound, or smell feel overwhelming?
Migraine can affect how the brain processes sensory input. Dr. Starling explained that people with migraine may process light, sound, smell, touch, motion, and pain differently, which can make ordinary sensations feel intrusive or overwhelming.
Can migraine sensory sensitivity happen between attacks?
Yes. Some people experience sensory sensitivity between attacks, especially with frequent or chronic migraine. Dr. Ailani described patients who remain highly sensitive to light, sound, or smell even between attacks.
Is sensory sensitivity the same as a migraine trigger?
Not always. Sensory input can sometimes contribute to migraine load, but sensitivity to light, sound, or smell may also be an early sign that a migraine process is already beginning.
What helps with migraine sensory overload?
Support often starts with reducing load and increasing stability. This may include softening harsh light, reducing background noise, stepping away from strong smells, using grounding or breathing techniques, keeping hydration and meals steady, and using sensory-safe tools that are easy to reach for.
When should I talk to a doctor about sensory symptoms?
Talk to a healthcare professional if sensory symptoms are new, changing, severe, or affecting your daily life. Seek urgent care for new weakness, trouble speaking, chest pain, severe dizziness, or major changes in vision.
