It happens the same way every year. The first proper rain arrives, the city cools down, everyone's relieved after the heat — and then, a few days in, your ears start feeling strangely full. Like you're underwater, or wearing invisible earplugs. You yawn, you try the old cotton-bud trick, you wiggle your jaw. Nothing quite fixes it.
Dr. Sanjeev Mohanty sees a genuine spike in exactly this complaint every time the rains set in around Chennai. It's not your imagination, and it's not "just weather." There's a real, explainable reason your ears act up during the monsoon — and understanding it makes the whole thing far less annoying to deal with.
Why humidity specifically targets your ears
Moist air doesn't just sit outside — it changes what happens inside your ear canal too. Warm, damp conditions are exactly what certain fungi and bacteria need to multiply, especially in a canal that's already a little narrow or prone to wax buildup. This is why fungal ear infections, known as otomycosis, become noticeably more common during and right after the rains — with itching, a feeling of fullness, and sometimes a faint, unpleasant smell.
On top of that, monsoon colds are simply more frequent, and colds bring congestion that travels straight to the eustachian tube — the same tube connecting your throat to your middle ear. When that tube is blocked, fluid can't drain properly, and you get that classic underwater, muffled feeling.
A pattern worth noticing
A lot of patients describe the exact same sequence without realizing it's a pattern: mild cold first, then a couple of days later, one ear starts feeling blocked or slightly painful, and it doesn't clear up even after the cold itself is gone. That lag — symptoms outlasting the cold — is the eustachian tube still trying to catch up, and it's one of the most common monsoon-season ENT visits there is.
What actually helps
• Keep ears genuinely dry after bathing or getting caught in rain — a soft towel pat is enough, no need to dig inside with anything
• Avoid cotton buds during this season specifically — they push moisture and wax further in rather than out, right when infection risk is already higher
• Don't ignore an itchy or "off" smelling ear, even if it doesn't hurt yet — early fungal infections respond very quickly to proper treatment
• If a blocked feeling lingers more than a week after a cold has cleared, that's the moment to get it examined rather than keep waiting it out
The part people underestimate
Most monsoon ear complaints are minor and treat quickly — but only when caught early. Left alone for weeks, fungal infections and fluid buildup can genuinely affect hearing temporarily and take much longer to resolve. A five-minute check during rainy season is a small habit that saves a lot of discomfort later.
If your ears have started doing "that thing" again this rainy season, it's worth getting looked at rather than just waiting for the season to pass.
