High Cortisol and Tinnitus
Your nervous system acts as your body's control center, constantly working to keep you balanced. But when stress lingers, your body releases excess cortisol—the primary stress hormone. Over time, elevated cortisol levels can disrupt multiple systems, including your hearing.
If you've ever experienced a persistent ringing in your ears after a stressful period, it's not just in your head. Tinnitus—the perception of ringing, buzzing, or hissing sounds without an external source—can be triggered or worsened by high cortisol levels.
How High Cortisol Affects Your Ears
While tinnitus has many causes, including exposure to loud noises and ear infections, stress-induced cortisol spikes can contribute to this frustrating condition by increasing inflammation, disrupting circulation, and overstimulating your nervous system.
1. Increased Inflammation in the Auditory System
Cortisol plays a key role in the body's inflammatory response. When stress is ongoing, excessive cortisol can cause inflammation in delicate structures like the cochlea (inner ear), leading to tinnitus.
Signs of Inflammation-Related Tinnitus:
- Ringing or buzzing that worsens during high-stress periods
- Ear discomfort or a sensation of fullness
- Sensitivity to sounds that didn’t bother you before
- Increased headaches or pressure around the ears
What Helps?
Reducing systemic inflammation through stress management with somatic exercises and hydration can help calm the auditory system.
2. Poor Circulation to the Inner Ear
Your body prioritizes survival under stress, meaning blood flow gets redirected to major muscle groups and away from “non-essential” functions—including your ears. When circulation to the cochlea decreases, tinnitus symptoms can flare up.
Signs of Circulation-Related Tinnitus:
- Temporary ringing after a stressful event
- Dizziness or lightheadedness accompanying the ringing
- Feeling like your ears aren’t “getting enough air”
- Tinnitus that worsens when lying down or standing up quickly
What Helps?
Hydration and somatic exercises can improve circulation to the inner ear and reduce tinnitus symptoms.
3. Nervous System Overstimulation
Cortisol keeps your nervous system on high alert, making you more sensitive to external stimuli—including sound. When your auditory system is in overdrive, even normal background noise can feel overwhelming, making tinnitus more noticeable.
Signs of Nervous System-Related Tinnitus:
- Ringing or buzzing that worsens at night when trying to relax
- Feeling easily startled by noises
- Sensory overload in loud environments
- Difficulty concentrating due to ear-related distractions
What Helps?
Regulating your nervous system with somatic exercises and vagus nerve stimulation can help reduce tinnitus severity.
How to Lower Cortisol and Calm Tinnitus
If high cortisol is contributing to your tinnitus, the key to relief is addressing the root cause—chronic stress. Supporting your nervous system, improving circulation, and reducing inflammation can help bring your body (and your ears) back into balance.
