You’re in the kitchen at six, and the extractor fan is already too much, so you switch it off. Then you lean your full weight into the edge of the bench, hips first, because that pressure is the first thing all day that has felt like relief. Someone brushes your shoulder in passing, barely a touch, and you flinch like you’ve been burned. Same room. Same hour. Same nervous system.
Sensory seeking and avoiding in autism can happen in the same person, on the same day, sometimes within minutes. A mixed sensory profile means some input arrives too strong (light touch, a humming fridge, flickering light), some arrives too faint (pain, hunger, firm pressure), and some you actively go looking for (deep pressure, bass, crunch, spinning). Which one you get depends on the sense, the load you are already carrying and the control you have over the input. Research on autistic adults finds this combination common, with wide variation from one person to the next.
What the research shows
- 94.4% of autistic adults surveyed reported extreme sensory processing on at least one sensory quadrant, with striking variability within the group. Crane et al. (2009)1
- Across 221 autistic adults and 181 comparison adults, the autistic group reported more over-responsivity in every sensory domain measured. Tavassoli et al. (2014)2
- A cluster analysis found a subgroup of autistic adults with elevated scores across all sensory areas, hyper- and hyporeactivity co-occurring. Elwin et al. (2017)3
- Of 49 autistic adults surveyed, nearly 45% reported hyperreactivity and sensory seeking together. MacLennan et al. (2022)4
Why you can crave pressure and flinch at a light touch
The contradiction has a name you can use: a mixed sensory profile. Some of your senses turn up too loud, some turn down too quiet, and some send you hunting for more. All three can live in one body.
From the inside it feels like inconsistency. You adore the heavy coat and can’t stand the collar. You play music at a volume that startles people, then come apart at a cutlery drawer. Somebody has probably called you fussy. The research describes what you already know, that one adult can vary enormously from one sense to the next1.
Hyper, hypo and seeking are three different things
Hypo and hyper sensitive autism get talked about as opposite ends of one dial. They behave like separate dials, one per sense, plus a third thing on top.
Hyper-reactive means input lands too strong or too fast: the tag, the chirping smoke alarm, a stranger’s hand arriving without warning.
Hypo-reactive means input lands faint or late. You notice the cut when you see the blood, the hunger when your hands shake. When your body’s own signals arrive late, interoception is usually part of the picture.
Seeking means you go and get input: the hottest shower, the crunchiest food, the spin on the office chair. Seeking often follows a quiet channel, since a faint signal gets turned up. It can also cover something you can’t bear, like the song in your headphones drowning the fridge.
Why “seeker” and “avoider” labels mislead
A label sorts you by your loudest moment. Answer a questionnaire after a good weekend and you’re a seeker. Answer it after a bad week and you’re an avoider. Both answers describe a sense on a day.
Behaviour hides the job it’s doing, too. Rocking can seek rhythm or hold off panic. Headphones on all day look like avoiding, and may be what lets you seek bass on the train home. A cluster analysis of autistic adults found more than one profile, including a group where heightened and reduced reactivity sat together and a group with little reduced reactivity3. No single type exists for you to be. For the sense-by-sense catalogue of seeking, see sensory seeking in autistic adults.
Load and control decide which way a sense swings
Take a hug from someone you love. On a quiet Saturday you want the whole squeeze. After a day in an open-plan office, the same arms feel like sandpaper. The input hasn’t changed. Your load has.
Load is whatever you’ve already spent: noise, masking, hunger, poor sleep, hours of other people. With room to spare, your system goes looking. As load climbs, tolerance narrows. When you’re full, everything registers as an attack, which is the territory of autistic overwhelm, sensory overload and what sensory overload feels like from the inside.
Control matters just as much. A sound you chose and can stop differs from one that arrives uninvited. Autistic adults in one survey named control and predictability as shaping sensory experience4.
“I’ll put on heavy headphones and play thunderstorm audio at full volume, then scream inside when my daughter taps my arm to ask what’s for tea. It took me years to see that one of those I chose.”

Pressure yes, light touch no
You may be tired of explaining this pairing. Firm pressure has edges. It’s steady, it’s predictable, and when you apply it yourself you control the amount. A fingertip on your neck is vague, arrives from outside and has no clear start or end. A nervous system that wants clear information can read firm as an answer and light as noise.
Treat that as a hypothesis to test. It fits plenty of lives: loving a bear hug and hating a tickle, wearing compression leggings and refusing a seam. Proprioceptive stimming sits on the seeking side of this split, and clothing sensitivity sits on the other.
How to read your own pattern by context and load
For one week, keep phone notes with four columns: the input, what else was happening (sleep, food, people, how long you’d been masking, time of day), what you did, and whether it helped. Rough is fine, and write it afterwards if your body signals arrive late.
Then sort the notes into three piles: reliably unbearable, reliably wanted, depends. The third pile is where the information lives. For each item, compare the day it went one way with the day it went the other: load, who was in control, whether you saw it coming.
A pattern usually appears within a fortnight. Maybe light touch is fine before noon and impossible after three. Maybe you seek bass only when you’re alone. Those are your own conditions, and they tell you more than any questionnaire score. For ideas on what to reach for, try sensory seeking activities for autistic adults.
Decades of masking hid the pattern from you too
Many of us spent years answering sensory input with a performance. Smiling through the hand dryer. Holding a hug past the point of bearing it. Taking the seat on the loud side of the table. Meanwhile the seeking went underground: the chewed pen, the long shower, the gym.
After a late diagnosis, telling your signals from the performance gets hard, because you overrode them for so long. Nobody gave you a profile to hang the contradictions on, so they sounded like character flaws.
“For forty years I thought I was either fussy or reckless. Fussy about the hand dryer, reckless with the volume. One nervous system, doing the arithmetic all day, and nobody told me.”

That slow re-meeting with your own responses, working out what is yours once the performance stops, is the ground The Unmasking Years covers, including a practical chapter on redesigning your environment around the nervous system you have.
What to do once you can see it
Build for the swing. Put your seeking input within reach before your load climbs, because the heavy coat helps more at two than at seven. Keep an exit for the flips, a quiet room or a pair of headphones, and read each flip as information.
Give the people near you instructions that fit. “Firm or not at all” works. So does “Tell me before you touch me.” Protect your control over input wherever you can, since you can change that most often. Expect the pattern to shift with sleep, season and stress.
Key points
- Seeking and avoiding can coexist in one body and one afternoon, and research on autistic adults finds the combination common.
- Hyper-reactive, hypo-reactive and seeking are three separate things, and each sense can run its own.
- “Seeker” and “avoider” labels describe a sense on a day.
- Load and control decide which way a sense swings.
- A week of notes sorted into unbearable, wanted and “depends” shows you your own conditions.
- Years of masking can hide your real responses, so your contradictions are often data.
Questions about sensory seeking and avoiding in autism
Can you be sensory seeking and sensory avoiding at the same time?
Yes. A mixed sensory profile means one body can seek some input, avoid other input and barely register a third kind, all in the same hour. One survey of 49 autistic adults found nearly 45% reported hyperreactivity and seeking together4. You might crave a firm squeeze and flinch at a light brush, or love loud music and hate a dripping tap. Different senses, or different loads, are answering differently, and each answer makes sense. Your nervous system is running several rules at once, each consistent on its own terms.
What is a mixed sensory profile in adults?
A mixed sensory profile combines over-responsiveness, under-responsiveness and seeking across different senses. You might be hyper-reactive to sound, hypo-reactive to pain and hunger, and a seeker of pressure and movement. Cluster research on autistic adults found a group whose hyper- and hyporeactivity co-occurred, alongside groups with other patterns3. The profile is yours alone, and it can shift with sleep, stress, season and setting, so one questionnaire score will never capture all of it, however carefully you answer it.
Why do I crave deep pressure but hate light touch?
Firm pressure is steady, has clear edges and, when you apply it yourself, sits under your control. Light touch is vague, arrives without warning and has no clear start or end. A nervous system that wants clear information can read firm as an answer and light as noise. Test this on yourself as a hypothesis. Your own notes will show whether pressure helps more when you are the one applying it, and whether light touch gets easier when you can see it coming. Both are worth recording.
Can you be hypersensitive and hyposensitive at the same time in autism?
Yes, in different senses and sometimes in the same sense on different days. You might hear the fridge from two rooms away and miss a burn on your hand until later. Surveys of autistic adults describe striking variability inside the group, with reactivity differing from sense to sense1. Hypo and hyper sensitive autism work as separate dials, one per sense, and load can turn any of them up or down on a given day, which is why no single day tells the whole story.
Why does my sensory seeking change from day to day?
Load changes it. Poor sleep, hunger, noise, masking and hours around people all shrink your tolerance, so input you sought on Saturday can feel like an attack on Thursday. Control and predictability matter too, because input you choose lands differently from input that arrives uninvited. Track what else was happening on the good day and the bad day, and the swing usually starts to make sense within a couple of weeks. Hormonal cycles, illness and changing seasons can move it too.
Is sensory seeking a sign of hyposensitivity?
Sometimes. Seeking often follows a quiet channel, since a faint signal gets turned up, which is why chasing intense flavours or deep pressure can sit alongside missing pain or hunger. Seeking can also follow a channel that is too loud, as when music in your headphones covers a noise you can’t bear. The behaviour looks identical from outside. Only you can tell which job it is doing, and the answer can differ between Monday and Friday, or between one hour and the next.
How do I know if I’m seeking or avoiding?
Watch what happens afterwards. If you feel more settled, more awake or more like yourself, you were probably seeking something you needed. If you feel braced, depleted or relieved that it stopped, you were probably avoiding. Many moments hold both, and that is entirely normal. A week of notes on the input, your load and the outcome will sort most of them, and the “depends” pile will show you the conditions that tip a sense one way or the other.
Does masking change how my sensory profile looks?
Yes. If you spent years smiling through the hand dryer and holding hugs you couldn’t bear, your real responses may be buried under a performance. The seeking often went underground too, as the chewed pen, the long shower or the gym. After a late diagnosis it can take a while to tell your real responses from the learned ones. The contradictions you were once told were fussiness are often your most useful data, so write them down without editing them.
