Protecting Your Hands: RSI Before It Starts

Repetitive strain injury doesn't announce itself. It arrives as a mild ache that you ignore for a few weeks. Then it becomes something you notice at the end of every day. Then it's something you notice all day. By the time most people take it seriously, they're already dealing with nerve damage, tendinitis, or carpal tunnel syndrome that takes months to resolve.

The best time to address RSI is before you have it.

The Numbers Worth Knowing

Knowledge workers type an average of 40 to 60 words per minute for 6 to 8 hours a day. That's somewhere between 14,000 and 30,000 keystrokes daily. Over a year, you're looking at 5 to 10 million repetitive motions in a relatively small set of muscles and tendons.

The body wasn't designed for that. Neither was the keyboard, which forces your wrists into an unnatural angle for hours at a time.

Warning Signs People Ignore

Tingling or numbness in the fingers, especially the ring and pinky fingers, is often the first sign. A dull ache in the forearm that persists after you stop typing. Wrists that feel sore when you wake up. Clicking or popping in the joints under load.

Any of these warrant a conversation with a doctor and an immediate audit of your setup and habits.

What Actually Helps

Breaks matter more than most people want to hear. The research is consistent: short breaks every 30 to 45 minutes reduce cumulative strain significantly. A 2-minute break every 45 minutes is more protective than a 20-minute break every 4 hours. The damage is cumulative in both directions.

Keyboard and mouse position matters. Your wrists should be roughly neutral, not bent up or down. Your elbows should sit at about 90 degrees. A wrist rest sounds helpful but can actually increase pressure on the carpal tunnel if used incorrectly. Use them for resting between typing, not while actively typing.

A split ergonomic keyboard reduces the forced inward rotation of the forearms. Not everyone adapts to them, but if you type for a living, it's worth the learning curve.

Where Voice Fits In

Dictation isn't a complete replacement for keyboard input, but it's one of the most effective ways to reduce your daily keystroke count without reducing your output. If you write 2,000 words a day and half of those come from dictation, you've cut your typing load by roughly 50%.

For people already managing RSI symptoms, voice is often described as the thing that kept them working. For people who are still healthy, it's a form of prevention that also happens to make them faster.

VoiceInk is a practical way to start on Mac. You dictate directly into whatever app you're using, there's no workflow change required. You can begin by dictating emails and messages, the high-volume text that doesn't require formatting precision, and see how much your typing load drops.

Habits Worth Building Now

If you're under 35 and don't have any symptoms, this article probably feels like it's for someone else. That's exactly when you should read it. RSI at 40 is treatable but disruptive. RSI at 28 is a crisis.

The people who avoid it aren't the ones who type less. They're the ones who paid attention to their setup, took breaks seriously, and varied their input methods before they had a reason to.

Your hands have about 40 more years of work ahead of them. Treat them accordingly.
