Why Do You Experience Sensitivity to Noise After a Concussion?
Most concussion patients will experience some form of either light or noise sensitivity and it’s mainly due to how the autonomic nervous system gets affected post concussion.
The autonomic nervous system regulates involuntary processes in the body including digestion, respiration, blood pressure, and heart rate. It is composed of the sympathetic system and the parasympathetic system.
When you experience a brain injury or concussion, you can lose the ability to inhibit both systems. The inability to inhibit the sympathetic system (which heightens your hearing acuity and dialates the pupils) will typically result in sensitivities to both light and sound.
What Can You Do?
Our team of concussion specialists share some tips to help manage your noise sensitivity after a concussion:
- Avoid noisy places & gradually work back into them
- Try wearing earplugs
- Get an adequate amount of sleep and rest
- Know your triggers
- Establish “quiet zones” where you can relax
