Deep Pressure Therapy

Deep Pressure Therapy is a sensory integration therapy that applies surface pressure to the body to create the feeling of a firm hug, hold, or swaddle. The result of applying pressure has a relaxing and calming effect by regulating the sensory system when it is overstimulated from environmental input and overload.

Johnny seeks pressure by squishing himself under the couch. "Deep pressure is sometimes a necessity in the same sense that oxygen and water are needed..."
—Danette, mother of Johnny with autism.
