How Light and Sound Sensitivity Might be Affecting Your Life

Our body has 12 cranial nerves that help regulate important information coming from the environment as well as information being regulated within your body. The optic nerve regulates light while the Vestibulocochlear (CN8) , Facial (CN7), and Trigeminal (CN5) helps regulate information regarding sound.


Optic Nerve

In our every-day life it is nearly impossible to avoid light whether it is artificial light or natural light from the sun. Obviously sunlight can be especially positive for you in terms of regulating vitamin D and helping to release hormones to boost your mood.


Sometimes though we may develop sensitivity to light due to a trauma or stressor. This means when exposed light it can affect your whole body causing issues such as headaches, weakness, migraines, poor vision, increased sensitivity to light and more. This can be especially detrimental after concussions.

Vestibularcochlear, Trigeminal, and Facial Nerves

There are a group of cranial nerves that take in sound information and when dysfunctional can magnify the effects and cause the body to shut down and have all sorts of negative side effects. The Trigeminal Nerve is related to soft sounds, the facial nerve is related to loud sounds, and the Vestibularcochlear nerve is related to normal decibel sounds.


If you've ever been in an area with a lot of sound and you find yourself uncomfortable, headaches form, your body begins to ache, or perhaps you feel like your body begins to shut down then you may be dealing with issues related to cranial nerve V, VII, VIII.


Client experience 1:

I recently had a client who came in and said she had thin walls in her apartment and could hear her neighbor making all kinds of noise. On top of that there was some construction located not too far away from where she lived which gave a high pitch metallic sound that caused all kinds of issues such as feeling dizzy, fatigue, feeling light-headed and more when she heard the specific noise. We spent a session working on corrections for all the sounds cranial nerves related to sound and even assessing specific frequencies. Upon her next visit she mentioned her neighbor (while still noisy) no longer had an effect on her mental state and her body along with no more issues coming from the construction site.


Client experience 2:

I was working with a client on some vestibular issues and one of the corrections we had to do involved sounds. While she never mentioned it before, upon her next visit she mentioned she had started working out again at a gym and she was never able to do so because of all the noise and sounds would really cause her issues. Sometimes you never know what kinds of life changes your corrections will lead to.


What P-DTR can do to help you:

P-DTR can be used to assess all 12 cranial nerves and see if someone has a de-conditioned nerve which may cause issues in the body when exposed to stimulus such as light and sound. Using the P-DTR protocol we can treat the cranial nerve and restore tolerance to stimulus, followed up by providing essential reconditioning for the nerve.
