How to Protect Your Hands Before RSI Makes the Choice for You

Repetitive strain injury does not arrive all at once. It builds quietly over months or years of small, repeated movements, then surfaces as a dull ache in your wrist, a tightness in your forearm, a tingling in two fingers that you initially blame on how you slept. By the time you recognize it, you are already managing a problem rather than preventing one.

For anyone who types for a living, the risk is real and the prevention is mostly boring. Do the boring things.

Understand What You Are Actually Doing

A person typing 40 words per minute makes roughly 200 keystrokes per minute. Over an 8-hour workday with normal breaks, that is somewhere between 80,000 and 100,000 keystrokes. Each one involves a small contraction in the forearm muscles, a micro-impact on the finger joints, a tiny movement through the wrist.

None of these movements is harmful in isolation. Accumulated across months and years, in awkward positions, without adequate recovery time, they add up to damage. The tendons and soft tissue around your wrists and hands have real limits, and modern knowledge work pushes against them daily.

The Setup Changes You Can Make Today

Keyboard height matters more than most people realize. Your elbows should be at roughly 90 degrees, forearms parallel to the floor or angled slightly downward. If your keyboard forces your wrists to bend upward to reach the keys, you are in a risky position every minute you type.

Consider a wrist rest, but use it between bursts of typing, not while actively typing. Resting your wrists on a surface while moving your fingers compresses the carpal tunnel. The rest is for pauses, not for active keystrokes.

Mouse position causes as much trouble as keyboard position. Reaching forward or to the side to use a mouse puts sustained tension on the shoulder and forearm. Keep it close.

Breaks Are Not Optional

The research on this is consistent. Short, frequent breaks are more protective than long, infrequent ones. A two-minute break every 30 minutes does more to reduce cumulative strain than a 20-minute break every two hours.

You do not need a formal stretching routine, though one would not hurt. Simply stopping, putting your hands in your lap, and letting your forearms rest for two minutes resets some of the accumulated tension. Do this before you feel you need to.

Reducing Keyboard Time Without Reducing Output

One of the most effective ways to lower keystroke count is to shift some of your text generation to voice. Emails, first drafts, notes, long-form writing: these account for a significant share of daily keystrokes, and they are the category most suited to dictation.

VoiceInk runs locally on your Mac, so there is no lag waiting for a server response. The experience is close enough to real-time that it works as a genuine replacement for typing in generative tasks, not just as an accessibility workaround. For someone managing early RSI symptoms, reducing daily keystrokes by even 30% can meaningfully slow progression.

This is not about eliminating typing. Editing, navigation, and code are still keyboard tasks. The goal is to stop using the keyboard for everything when some things can be done with your voice and no hand involvement at all.

Symptoms That Mean See Someone

Persistent aching in the forearm or wrist after you stop working is a signal. Numbness or tingling in the fingers, especially the thumb, index, and middle finger, can indicate carpal tunnel compression. Weakness in your grip that was not there six months ago is worth investigating.

A physiotherapist who works with repetitive strain can assess your specific situation and give you targeted advice. Self-managed stretching routines from the internet are not a substitute for that.

The best time to address this is before it is urgent. If your hands are fine right now, keep them that way. If they are not quite fine, start taking it seriously before "not quite fine" becomes something harder to reverse.
