Hyposensitivity, also known as Sensory under-responsitivity, refers to abnormally decreased sensitivity to sensory input.

Hyposensitivity is a symptom of sensory processing disorder, and is most commonly seen in autistic (or ADHD) people. Those experiencing hyposensitivity have a harder time stimulating their senses than normally. They may not feel pain as easily as others, may be drawn to loud noises, be attracted to bright lights and colours, among other things.

Hyposensitivity can lead to concentration problems, feeling drained, depression, procrastination and also hypersensitivities.
