Sensory processing disorder—also known as SPD or sensory integration disorder—is a term describing a collection of challenges that occur when the senses fail to respond properly to the outside world. Though the condition has gained recognition in recent years, it is widely debated and is not currently an official DSM diagnosis.
The Sensory Processing Disorder-Physical Health Connection
The relationship between sensory processing disorder and physical health is bidirectional and profound. Modern neuroscience has confirmed what clinicians long observed: psychological states directly impact bodily systems.
Physical Symptoms of Sensory Processing Disorder
People managing sensory processing disorder commonly experience:
- Fatigue and low energy
- Headaches and muscle tension
- Digestive disruptions (IBS, nausea, appetite changes)
- Sleep disturbances affecting cellular repair
- Immune system dysregulation
- Cardiovascular effects (blood pressure, heart rate variability)
- Chronic pain amplification
How Sensory Processing Disorder Affects Body Systems
Stress hormones: Sensory Processing Disorder often elevates cortisol and adrenaline, which when chronically elevated cause inflammation, insulin resistance, and immune suppression.
Nervous system: The autonomic nervous system shifts toward sympathetic dominance ("fight or flight"), reducing digestive, immune, and reproductive function.
Inflammation: Psychological distress promotes inflammatory cytokines linked to heart disease, diabetes, and autoimmune conditions.
Physical Health Practices That Help Sensory Processing Disorder
Research shows these interventions improve both sensory processing disorder and physical health simultaneously:
- Regular aerobic exercise — 30 min, 3–5× weekly reduces symptoms significantly
- Anti-inflammatory diet — Mediterranean diet pattern supports mood and reduces inflammation
- Sleep optimization — 7–9 hours consistently transforms sensory processing disorder outcomes
- Breathing practices — diaphragmatic breathing activates parasympathetic recovery
- Reducing alcohol and processed foods — both worsen sensory processing disorder symptoms
When to Seek Integrated Care
Look for healthcare providers who address both physical and psychological dimensions if sensory processing disorder is affecting your body. Integrative psychiatry, functional medicine, and psychosomatic medicine specialize in this overlap.
