Senses and the body
An overview of autistic sensory experience: the patterns research describes, stimming, sensing the body's internal signals, and eating and sleep. Each section links to a full entry.
A short tour of how autistic people sense the world and their own bodies. Each part links to a longer page.
Sensory experiences and overload Established
Research describes three broad patterns: ordinary input feeling too strong, reacting little or late, and seeking more input. A meta-analysis of 55 questionnaire studies found large differences between autistic and non-autistic people on all three.1
Full entrySensory experiences and overload What over-responsivity, under-responsivity and sensory seeking are like for autistic people, how they relate to daily life, what overload, meltdown and shutdown feel like from the inside, and what research shows about changing the sensory environment.For some autistic people, sounds, lights or textures feel much too strong. Others notice them less, or look for more. Many studies have found these differences.1
Full entrySensory experiences and overload What it is like when sounds, lights, touch and smells feel too strong or too weak, how this affects daily life, what overload feels like, and what helps when places change.Summarizes Sensory experiences and overload. A meta-analysis supports the three patterns; accounts of overload come from small qualitative studies.
Many studies agree on this.
Stimming Established
In interviews and focus groups with 31 autistic adults in England, stimming was described as self-regulation that soothes or communicates intense emotions.2
Full entryStimming Repetitive movements, sounds and sensations that many autistic people use to calm down, focus or show feeling. How the community uses the word, where it came from, what studies of autistic adults report, and the long effort to stop it.Stimming means repeating a movement, sound or feeling. In one study, autistic adults said it helps them calm down or show strong feelings.2
Full entryStimming Stimming means moving, making sounds or feeling things over and over to calm down, focus or show a feeling. Here is what autistic people say about it, where the word came from, and what studies show.Summarizes Stimming. Several independent groups agree on what autistic adults report; the entry also covers how the community uses the word.
Several studies agree on what autistic adults say.
Interoception Established
Interoception is the sense of what is happening inside the body, such as heartbeat, hunger, thirst and the bodily side of emotions.3 Across studies using one questionnaire, about half of autistic participants scored in the range for alexithymia, difficulty identifying one's own emotions, against about 5% of non-autistic participants.4
Full entryInteroception How autistic people sense hunger, thirst, heartbeat and other signals from inside the body, what lab tasks and questionnaires show, how much of it is tied to alexithymia, and how it links with anxiety.Interoception means noticing what is going on inside your body, like hunger or a fast heartbeat.3 About half of autistic people in some studies found it hard to name their own feelings.4
Full entryInteroception How autistic people notice signals from inside the body, like hunger, thirst and heartbeat. Scientists have tested this in many ways, and the results are mixed.Summarizes Interoception. The alexithymia figure comes from a meta-analysis using one questionnaire; findings on body-signal tasks are less settled.
Many studies agree, but they mostly used the same questionnaire.
Eating and sleep Established
A meta-analysis of 17 studies found the odds of feeding problems about five times higher in autistic children.5 A 2026 meta-analysis of 22 studies put the rate of sleep disorders in autistic children and adolescents at 60%, though it had no comparison group.6
Full entryEating and sleep How eating and sleep differ for many autistic people, from selective eating and its overlap with ARFID and anorexia to how common sleep problems are, what the melatonin trials found, how CBT-I has been tested in autistic adults and how hard sleep care is to reach, and what body-clock studies suggest. A research summary, not medical advice.Many autistic kids eat only a small number of foods.5 Many also have trouble sleeping.6
Full entryEating and sleep How eating and sleep can be different for autistic people. It covers picky eating, eating disorders, sleep trouble, melatonin, how CBT-I has been tested, and the body clock. It shares research. It is not medical advice.Summarizes Eating and sleep. Meta-analyses agree for children; the adult evidence is smaller.
Several big reviews of children agree.
