The Honest Guide to Preventing RSI Before It Starts

Repetitive strain injury has a cruel feature: by the time most people take it seriously, they've already had symptoms for months. The ache in the forearm, the tingling in the fingers at night, the wrist that doesn't feel quite right after a long day. These are not early warning signs. They are late ones.

The time to act is before any of that.

What RSI Actually Is

RSI is not one injury. It's a category covering tendinitis, carpal tunnel syndrome, cubital tunnel syndrome, and several other conditions caused by repeated mechanical stress on the same tissues. Typing is one of the most common triggers, not because any individual keystroke is harmful, but because the cumulative load over years adds up.

A developer or writer who types 40 hours a week makes roughly 8 to 12 million keystrokes per year. Most tendons and nerves handle that fine for a decade or two. Then they don't.

The Ergonomics That Actually Matter

A lot of ergonomics advice focuses on equipment: standing desks, split keyboards, vertical mice. That equipment helps, but the research suggests that behavior matters more than gear.

The three things with the strongest evidence behind them:

Breaks at fixed intervals. Not when you remember. Not when you finish the paragraph. Every 25 to 30 minutes, stop for at least two minutes. Stand up. Let your hands hang at your sides. The Pomodoro technique exists for productivity reasons, but it's also decent RSI prevention by accident.

Wrist position during typing. Your wrists should be roughly neutral, not extended upward or bent downward. Most laptop keyboards encourage slight extension. A keyboard tray or external keyboard placed lower can correct this.

Grip and force. Typists underestimate how hard they press keys and how tightly they grip a mouse. Mechanical keyboards with lighter switches reduce bottoming-out force. Conscious effort to use a lighter grip on the mouse pays off over time.

Where Voice Dictation Fits In

Voice dictation is not a cure for RSI and shouldn't be marketed as one. But it is a genuine way to reduce keystroke volume for the specific task of producing prose.

If you're a writer or someone who spends several hours a day producing long-form text, dictating that text instead of typing it can cut your daily keystroke count significantly. Email, documentation, notes, drafts: a lot of what knowledge workers type is words in sequence, not code or structured input. That portion translates well to voice.

Tools like VoiceInk are useful here precisely because they have low friction. If dictation requires a complicated setup or a separate app, you won't use it consistently enough to matter. The lower the barrier, the more likely you actually shift some load off your hands.

What to Do If You Already Have Symptoms

See a doctor or physiotherapist who specializes in occupational injuries. This is not optional advice. RSI conditions that are caught early are almost always manageable. RSI conditions that are ignored for a year or more can become chronic and significantly harder to treat.

While you're getting that sorted, reduce your typing volume, not by working less, but by shifting what you can to voice and being honest about your total keyboard time per day. Most people significantly underestimate it until they actually measure.

The Unsexy Truth

There's no single intervention that prevents RSI. Not a specific keyboard, not a standing desk, not dictation software. What prevents it is sustained attention to load: how much, how often, and whether you're giving your tissues time to recover.

Most people give that attention only after pain starts. The ones who don't end up with more typing years ahead of them.

If you're curious whether shifting some of your prose output to voice makes sense for your situation, it costs nothing to try a session or two and see how your hands feel at the end of the day.
