When your immune system responds to allergens, it doesn’t do a great job of containing its response. Allergic responses can cause headaches, sinus pressure, runny noses and more. That’s because your own immunological response takes a full-body approach.
How Does the Immune System Respond to Allergens?
Histamine receptors are what bind to histamine, typically produced by the body in response to an allergen. Once bound to a histamine, histamine receptors tell G-proteins to trigger a physiological response. That response is different for each of the four histamine receptors, but they are all working to help the body combat invading allergens.
Something like swelling, which is bad in the long term, can be good in the short term. It helps pull immune cells into the affected area, while plasma proteins swell to help contain or neutralize threats. Swelling also slows movement, forcing the body to slow down.
Are Tinnitus and Allergies Connected?
A large-scale study involving 138,361 patients with tinnitus1 and 384,895 control subjects. The study identified a statistically significant correlation between tinnitus sufferers and pre-existing allergic rhinitis (AR).
Study participants with allergic rhinitis were much more common in the tinnitus group than in the control group.
- AR prevalence in tinnitus patients: 31.66%
- AR prevalence in controls: 19.64%
- Reported p‑value: p < 0.001
A p‑value below 0.001 means there is less than a 0.1% probability that this difference occurred by random chance alone—a very strong level of statistical significance.
The study also accounted for other variables, including hearing loss, anxiety and depression, metabolic conditions, otitis media, and lifestyle factors.
The study also analyzed:
- Chronic rhinosinusitis (CRS) alone
- AR + CRS combined
All showed statistically significant associations with tinnitus:
- CRS: OR = 1.626
- AR + CRS: OR = 1.751
- All results reported p < 0.001xds
The highest risk for tinnitus was observed in study participants with both chronic rhinosinusitis and allergic rhinitis.
Why Would an Allergic Response Make Tinnitus Worse?
Studies have identified 4 different histamine receptors at various points within the auditory system2, including the semicircular duct and vestibular ganglion.
There are a wide range of ways allergies can impact hearing, like Eustachian tube blockages, which can cause fluid buildup, pressure and muffled hearing. The connection to tinnitus gains clarity when we look at neuronal excitability. An excited neuron is a state of readiness. In the case of an inner ear neuron, just one important part of a tiny hair filament that converts sound vibrations into electrical signals the brain can interpret, excitement can increase the electrical signal it produces relative to the actual vibration it receives.
Because histamine can excite neurons3 in the inner ear, and swelling due to allergies can trap histamines in the inner ear, an allergic response can create a heightened awareness of tinnitus symptoms, making it feel like the volume has been turned up.
How Long Can Allergy-Related Tinnitus Symptoms Last?
These symptoms can persist for the duration of the allergic reaction and may get worse if your allergic response hasn’t reached its peak.
That’s why we recommend getting treated. Whether you’re starting with OTC medications or scheduling with a Lakelands ENT allergist, if you already have tinnitus symptoms, make an appointment before your typical allergy season. In South Carolina, it’s ragweed time, so if those allergens have impacted you in the past and you haven’t yet been treated, now is the time.
