Protect Your Wrists Before They Force You To

Repetitive strain injury doesn't announce itself. One day your wrists feel fine. Over months, there's a faint ache. Then the ache is there most days. Then you're in a physiotherapist's office being told to rest for six weeks, and six weeks of work suddenly need to be rescheduled.

This is a predictable progression, and most of the people who go through it say the same thing: they saw the early signs and assumed it would pass.

The Numbers Behind the Damage

The average office worker types between 40 and 60 words per minute for several hours a day. At 50 words per minute for four hours, that's roughly 12,000 words, or somewhere around 60,000 to 70,000 keystrokes per day. Each keystroke is a small repeated motion, and tendons don't have a great blood supply, which means they heal slowly and degrade steadily under chronic load.

Carpal tunnel syndrome, tendonitis, and general wrist strain are among the most common occupational injuries for knowledge workers. They're also among the most preventable.

What Actually Helps

Ergonomic keyboards help. Wrist rests help. Taking breaks helps. These are all real, and if you type heavily, you should be doing all of them.

But the most effective intervention is reducing total keystroke volume, not just making each keystroke slightly more comfortable. That's where voice input makes a structural difference.

Using VoiceInk to dictate emails, notes, and first drafts on your Mac can cut your daily keystroke count by a significant margin without cutting your output. You're not working less. You're routing the same work through a different physical channel.

The Asymmetry of Recovery vs. Prevention

A moderate RSI takes four to eight weeks to meaningfully recover from. During that time you're either working through pain, which makes it worse, or you're not working at your normal capacity. Either way, you lose.

Prevention costs almost nothing in comparison. Learning to dictate takes a few sessions. Adding it to your workflow for emails and rough drafts takes a week of adjustment. The return on that investment is measured over years.

What to Offload First

If you want to reduce hand fatigue without overhauling how you work, start with high-volume, low-precision tasks. Emails are the obvious target. Most emails don't require careful keystroke-level editing. You're expressing a thought, and voice is faster for that.

Meeting notes are another easy win. Long Slack threads, journal entries, draft outlines: all of these are places where dictation reduces load without changing the quality of the output.

Keep typing for the things that genuinely need it: code, precise edits, anything that requires character-level control. But you'll probably find that category is smaller than you think.

Notice the Early Signs

Wrist ache after long sessions, numbness or tingling in the fingers, stiffness in the morning that takes time to work out. These are the signals that most people explain away for months before they act.

If any of those sound familiar, now is exactly the right time to change the ratio of typing to speaking in your day. Not after the six-week rest, before it.

Voice dictation on Mac has gotten fast and accurate enough that the barrier to starting is low. Try it on your next email and pay attention to how your hands feel at the end of the day.
