Typing ergonomics: the setup that prevents pain
Chair and desk height
Adjust the chair first: sit with your forearms parallel to the floor and elbows at about 90 to 110 degrees while typing. If that raises your feet off the floor, you need a footrest or a lower desk, not a new chair. The desk should let your arms reach the keyboard without shrugging the shoulders. One test: drop your arms to your sides, then lift your hands to the keys. If the shoulders move, the setup is wrong.
Wrists and forearms
Type with wrists neutral: straight in line with the forearms, not bent up like a typewriter pose. They should float above the desk, moving with the fingers. A padded wrist rest is for resting between bursts, not a platform to type on; compressing the wrist against a pad all day is a classic route to numbness. Keep the laptop story honest too: a laptop keyboard under a raised screen forces one of the two into a bad position, which is exactly what external keyboards are for.
Screen and eyes
Place the screen about an arm's length away with the top third at eye level, so the gaze drops slightly for reading. Eye strain follows the 20-20-20 rule: every 20 minutes, look at something about 6 meters away for 20 seconds. This is not folk wisdom; it rests on the focusing muscle of the eye fatiguing at a fixed distance. Scratchy, dry eyes at the end of the day are a report that the breaks did not happen.
Breaks beat equipment
No chair, split keyboard or standing desk fixes a day without breaks. The strongest lever is frequency: stand, roll the shoulders and walk a minute every 30 minutes or so, and take a real five-minute break every couple of hours. Two 5-minute breaks move more health markers than an expensive chair upgrade, and they are free. If you buy one thing before a keyboard, buy a timer that reminds you to move.
Keyboards, honestly
Mechanical keyboards help some people: longer travel and lighter springs can reduce bottoming-out force. Split and tented boards genuinely help typists whose pain follows shoulder or forearm tension, because they let the hands rest at shoulder width. But layout is comfort, not cure: no keyboard fixes a bad chair height or a 3-hour unbroken session. Try before you buy, and prefer switches in the 45 to 60 gram range.
Warning signs to respect
Normal practice can feel like mild muscle tiredness. Tingling, numbness, sharp wrist pain or pain that keeps going after you stop typing are not training effects. Stop the practice, fix the setup, and see a doctor if symptoms persist. This article is about workspace habits, not medical advice, and treating overuse pain as weakness to push through is how short problems become long ones.
Tools
Type Sprint sessions are naturally short: one run is one to two minutes, so a practice block is easy to insert between breaks instead of instead of them. The history view shows when you actually practiced, which makes missed breaks visible. Everything runs in the browser, so the setup costs nothing.
