Subtitles: A Modern Convenience or a Hidden Clue?

Subtitle use has skyrocketed in recent years. In fact, a 2022 survey by Preply found that more than 50% of UK adults regularly use subtitles — and surprisingly, many of them don’t have diagnosed hearing loss.

For a growing number of people, subtitles are not just helpful — they’re essential. If you:

• Struggle to follow dialogue unless subtitles are on

• Miss punchlines, character names, or emotional cues

• Constantly feel the actors are “mumbling”

• Get told the TV is too loud by others in your household

…then your brain may be compensating for subtle changes in your hearing — and subtitles might be doing more than just clarifying accents.

What Happens to Your Brain and Ears When You Rely on Subtitles

When we use subtitles regularly --- two key things happen:

1. Auditory Processing Gets Less Practice

Your brain is designed to process sound automatically, using fine cues like pitch, speed, and direction to make sense of speech. When you rely on subtitles, your visual system takes over, and your brain has fewer opportunities to practice decoding sound. Over time, this can weaken auditory processing, making it even harder to follow speech without the visual support.

2. Cognitive Load Increases

Reading subtitles and watching a show at the same time creates split attention. For people with hearing loss, this can increase mental fatigue, especially during fast-paced dialogue. It’s why you might feel tired after watching TV — your brain is working harder than it should just to keep up.

Researchers have shown that people with untreated hearing loss often recruit extra brain areas to compensate — especially those used for memory and focus. This can reduce cognitive reserve and has been linked to increased risks of cognitive decline over time (source: Lancet Commission on Dementia Prevention, 2020).

The Gradual Nature of Hearing Loss

Most hearing loss in adults happens slowly — so it’s easy to ignore the signs. You adapt without realising:

• Turning the TV up just a little more

• Guessing what someone said instead of asking

• Laughing along even when you didn’t catch the joke

Subtitles can mask these changes, which is why they’re such a common early clue.

Why Early Action Matters

Untreated hearing loss doesn’t just affect your ears — it affects your brain, mood, relationships, and even long-term health.

Studies show that those who take early action often adjust more easily to hearing aids and other solutions — because their brain has stayed “in practice.”
