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

A comprehensive, research-grounded visual explaining why firm body input can calm, organise, and ground the nervous system.

This infographic covers:

• What's happening: deep pressure stimulates proprioceptors in muscles, tendons, and joints, giving the brain strong information about where the body is in space
• Anatomical detail: proprioceptors, spinal cord, brainstem (integrates sensory information, supports arousal regulation), sensory gating, autonomic regulation, body map/spatial awareness
• The signal pathway: deep pressure input is applied → receptors detect it → signals travel through the spinal cord → the brain gets clearer body-position information → competing sensory input may feel less dominant → arousal can shift downward
• What it can support: reduced physiological arousal, easier settling after overload, improved body awareness, better focus, a sense of containment and calm
• Autonomic regulation: firm even pressure may help shift the nervous system from sympathetic activation toward parasympathetic regulation; studies link deep pressure with reduced heart rate and calmer breathing
• Neurochemistry & body mapping: proprioceptive input associated with calming effects; deep pressure linked in the literature to reduced cortisol and changes in serotonin/dopamine-related regulation
• What actually helps: offer deep pressure only if sought or well-received, use safe options (weighted items, compression garments, OT-guided strategies), watch for consent and signs of overload
• Grounded in research including Grandin (1992); Reynolds, Lane & Mullen (2015); Ayres Sensory Integration frameworks
