Protect Your Hands: Reducing Typing Strain Before It Becomes RSI

Most people who develop repetitive strain injury don't see it coming. There's no single moment of injury. There's just a slow accumulation: a tightness in the forearm that goes away overnight, a mild ache in the wrist after a long day, an occasional numbness in two fingers that seems minor. Until it isn't.

RSI affects roughly 1 in 50 workers, and knowledge workers who type for a living are disproportionately represented. The time to address this is before it becomes a diagnosis.

What's Actually Happening

Typing involves small, repetitive contractions of the tendons and muscles in your forearms and hands. Over thousands of repetitions, the surrounding tissue becomes inflamed. The inflammation doesn't always cause sharp pain, especially early on. It causes tightness, fatigue, and reduced range of motion that builds slowly over months or years.

The average office worker types between 40 and 60 words per minute for several hours a day. At 50 words per minute over four hours, that's roughly 12,000 words, and somewhere between 60,000 and 70,000 individual keystrokes. Every day.

The Ergonomic Basics That Actually Matter

The most effective ergonomic change most people can make is also the simplest: stop typing with your wrists resting on the desk. Your wrists should be neutral or very slightly elevated when your hands are on the keyboard, not bent downward. A wrist rest sounds helpful but often encourages the wrong position during active typing.

Keyboard position matters too. Your elbows should be at roughly 90 degrees, with your keyboard at elbow height or just below. If your keyboard is on a standard desk and your chair is too low, your wrists are likely bent upward all day.

Take a look at your mouse hand. Most people hold their mouse in a grip that's far tighter than necessary. Loosen it. The mouse doesn't need to be held. It needs to be guided.

Reduce Volume, Not Just Posture

Posture changes help, but the most direct way to reduce strain is to type less. This sounds obvious. It is harder to act on than it sounds.

Voice dictation is one practical path. Using VoiceInk to handle long-form writing, email drafts, and notes cuts keyboard time significantly without cutting output. For someone writing 3,000 or more words a day, shifting half of that to dictation can meaningfully reduce the daily keystroke count.

This isn't about avoiding the keyboard entirely. It's about load management. Surgeons limit certain hand-intensive activities outside of operations. Writers and developers don't often think the same way about their hands, but the principle applies.

Breaks: The Specifics Matter

Taking breaks helps, but the way most people take them doesn't. Walking to get coffee and then returning to scroll your phone is not a break for your hands.

A useful break means putting your hands completely at rest. No phone, no keyboard. Shake your hands out gently. Open and close your fingers a few times. Let your forearms rest flat on your thighs, not on a desk edge.

Five minutes every 45 to 60 minutes of typing is a reasonable target. Apps like Time Out for Mac can prompt you on a schedule if you forget.

If You Already Have Symptoms

If you're already experiencing regular discomfort, tightness, or numbness, see a physiotherapist before assuming it will resolve on its own. RSI responds well to early intervention and poorly to being ignored.

In the meantime, reducing typing volume, adjusting your setup, and building in rest are all steps you can take immediately.

Your Hands Are a Long-Term Asset

A keyboard career spans decades. The habits you build now compound in both directions. Small protective changes made early have a large effect over time. Ignoring early warning signs has the same compounding quality, just in the wrong direction.

If you've been curious about dictation for any reason, reducing hand strain is as good a reason as any to give it a real try.
