Everyone has a different sensory profile, meaning their brains process information from their senses to different degrees, paying more attention to information from some senses and less to others.

In autistic individuals, the differences in their sensory profile can be significant. They can be very high sensitivity to some things like noise, light, texture, temperature, smell, and so on. This means they can find certain environments overwhelming, even though their non-autistic peers feel perfectly comfortable in them. At the same time, individuals can also have very low sensitivity to other things, such as pain, cold, or strong flavours, meaning individuals can endure situations non-autistics find intolerable.
