The Physiology of Deep Pressure Input

The Physiology of Deep Pressure Input — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

Deep pressure input is firm, distributed pressure applied through the body — weighted items, compression, hugs or body-based support — that can help some autistic and sensory-sensitive people feel calmer, more organised, and more aware of their body in space.

This infographic covers:

• What's happening — how deep pressure stimulates proprioceptors in muscles, tendons and joints, and why body-pressing is understood in occupational therapy as an adaptive sensory strategy, not a behaviour problem
• The signal pathway — six steps from pressure input through proprioceptor detection, spinal cord transmission, brain processing, sensory gating, to a calmer, more organised state
• What it can support — reduced physiological arousal, easier settling after overload, improved body awareness, better focus, containment and safety, and reduced distress from competing input
• Autonomic regulation — how firm, even pressure shifts the nervous system from sympathetic activation toward parasympathetic regulation, linked to reduced heart rate and calmer breathing
• Neurochemistry & body mapping — proprioceptive input's links to cortisol, serotonin and dopamine regulation, and a clearer internal body map
• What actually helps — offering deep pressure only when sought, using safe options (weighted items, firm pillows, compression garments), watching for consent and overload signs, and recognising individual response varies
• Research/source — grounded in deep pressure stimulation, proprioception and sensory gating research, referencing Grandin (1992), Reynolds, Lane & Mullen (2015), and Ayres Sensory Integration frameworks

Every autistic person is unique. Strategies and supports should always be tailored to the individual's needs, strengths, and circumstances.

If a child displays a sudden change in behaviour, severe distress, signs of illness, injury, or behaviours that place themselves or others at risk, seek appropriate medical advice or emergency assistance where necessary.

While every effort has been made to ensure the information is accurate and reflects current understanding, knowledge in autism and neuroscience continues to evolve.
