Many symptoms that individual's experience are due to sensory processing difficulties.
Headaches can be due to light sensitivity. Difficulty sleeping can be due to low proprioception. Panic can be due to auditory overwhelm. Anxiety can be due to olfactory sensitivity. Postural slump can be due to low muscle tone. Dizziness can be due to a weak vestibular system. Feelings of skin discomfort can be to irregular tactile processing. Many behaviors that individual's exhibit are strategies to cope with sensory overwhelm.
Physical aversion can be due to tactile sensitivity. Strong emotional responses can be due to olfactory sensitivity. Fussy eaters may have sensitive taste buds. Refusal to groom, brush teeth , or dress, may be due to tactile sensitivity. Avoidance of movement may be due to vestibular overwhelm. Aversion to crowds may be to proprioceptive overwhelm. Head hanging may be due to light sensitivity.
Many behaviors that individual's practice are strategies to increase sensory input deficiency.
Pushing increases proprioception. Jumping incessantly increases vestibular input. Looking at people sideways increases peripheral vision. Turning your ears towards people makes it easier to hear. Banging your head can stop overwhelming tactile or vestibular processing. Holding your breath increases your ability to balance and listen. Shouting can limit vestibular overwhelm.
But for children, these strategies aren't always the best way to make friends, attend school, have fun. Adults who have learned not to do these things to help themselves may suffer through life coping with underlying sensory struggles.
Please read the following PDF from the HANDLEŽ Institute The Real Reasons Kids Don't Learn for a detailed explanation of sensory systems and the symptoms associated with their imbalances. These explanations apply to children and adults alike. If you see yourself or some one you love described here, you may wish to make an appointment for sensory and structural integration.
