Tight shoulders at the computer: why it happens and what helps

It's 4 pm after hours of email. Reaching for the mouse, you find your shoulders up near your ears. You let them drop, and they feel tight.

Shyam Verma, 21 years on laptops.

The short answer: for shoulder pain from computer work, start with the desk. Let your shoulders drop, keep the keyboard at elbow height and the mouse right beside it, and get up for five minutes every hour. If the pain gets worse or doesn't ease after 2 weeks, see a doctor. ^1,2,4,7,9

Can my Mac tell when my shoulders are tense?

No. Poxture App can't measure tension or pain in your shoulders. It checks your posture through your Mac's camera for habits that involve your shoulders, like hunched over on a laptop, leaning to one side and slouching. When one holds for about half a minute, by default, a soft glow nudges you and a card shows the fix. Camera images never leave your Mac.

What causes shoulder tension at a desk?

Usually it's the setup. Your shoulders end up holding your arms up, or holding still, all day.

The keyboard sits too high. When the keys are higher than your elbows, you lift your shoulders to reach them. OSHA says a keyboard that's too high can make you raise your shoulders to lift your arms.¹

The mouse sits too far away. A mouse out past a full keyboard keeps your arm out to the side. OSHA says your shoulder and neck muscles then keep working to hold the arm away from your body. Reaching for it again and again can tire the shoulder muscles, too.^1,2

The screen sits too high or too low. OSHA says a screen at the wrong height puts your head, neck and shoulders in awkward positions.³

You're hunched over a laptop. The screen sits low, so your shoulders roll forward to reach it.

You stay still. Holding one position for a long time without a break can tire your neck and shoulder muscles, OSHA says.⁴

Stress. Cleveland Clinic lists muscle tension among the physical signs of stress. A 2013 study of 117 office workers measured shoulder muscle activity at their own desks. Those with high over-commitment and low reward had slightly more activity in the trapezius, the muscle across the top of the shoulders. The study can't say that this leads to pain.^5,6

What helps tight shoulders from computer work?

Let your shoulders drop. Let them hang relaxed, with your upper arms by your sides and your elbows close to your body. That's OSHA's neutral posture.⁷
Keyboard at elbow height. Raise the chair or lower the keyboard until your elbows sit about level with the keys. Then you don't lift your shoulders to type.¹
Bring the mouse in. Keep it right beside the keyboard. A keyboard without a number pad leaves more room for it, OSHA says.²
Lower the armrests. Set them low enough that your shoulders stay relaxed, just touching your forearms. Armrests that are too high keep your shoulders raised, OSHA says. If they're in the way, take them off.⁸
Get up every hour. Every hour, take five minutes away from the screen, OSHA suggests. Stand up, stretch and walk around.⁴

When should I see a doctor or physio?

See a doctor if your shoulder pain gets worse, doesn't ease after 2 weeks, or makes it very hard to move your arm, the NHS says. In many areas you can book a physio yourself. Ask for an urgent appointment if the pain is sudden or very bad, you can't move your arm, or you have pins and needles that don't go away. Chest pain that spreads to your arm, neck or jaw is an emergency: call 911 in the US, 999 in the UK, or your local emergency number. This page covers a desk habit, and it can't tell you why your shoulder hurts. If something hurts, see a professional.^9,10

Our app

What does Poxture App do about tight shoulders?

Poxture App can't feel or measure tension in your shoulders, and it can't tell you why they hurt.

It checks your posture through your Mac's camera, once a minute, for four habits that involve your shoulders, all on by default. When one of the first three holds for about half a minute, by default, a soft glow at the top of your screen tells you. A card shows the fix:

Hunched over: on a laptop, closer than your good posture with your back rounded or your head tipped. The card says "Sit back and let your shoulders drop."
Leaning to one side: your shoulder line tilted to one side, and staying there. The card says "Sit evenly on both hips." It needs your shoulders and upper body in the camera's frame.
Slouching: sinking lower than your good posture. The card says "Sit back into your chair and lift your chest."
Sitting still too long: 40 minutes at your desk without standing up or stepping away, by default. The card says "Stand up or step away from your desk."

When you've fixed it, the glow turns green. If the nudge is still showing after 30 seconds, one soft chime plays. You can switch the chime off.

To be honest, it doesn't check whether your shoulders are raised toward your ears, or where your keyboard and mouse sit. At an external monitor it doesn't nudge you for hunched over yet. Those parts are up to you.

Your camera images never leave your Mac.

Poxture App runs on Apple Silicon Macs with macOS 15 or later. The first hour of checking each day is free for good. For your first 14 days, every feature works all day. To keep it on all day, it costs $19 once.

Questions people ask

Why do my shoulders get tight at the computer?

Check the desk before anything else. A keyboard that's too high makes you lift your shoulders, and a mouse that's too far away keeps your arm held out. Holding one posture for a long time without a break can tire your neck and shoulder muscles too. Stress can add muscle tension of its own.^1,2,4,5

Where should my mouse go to ease my shoulders?

Right beside the keyboard. OSHA says a mouse placed too far away keeps your shoulder and neck muscles working to hold your arm out. A keyboard without a number pad leaves more room for it.²

How do I relax my shoulders at my desk?

Let them drop, with your upper arms by your sides and your elbows close to your body. Put the keyboard at elbow height and the mouse right beside it, so nothing holds your arms up. For shoulder pain, the NHS suggests sitting without rolling your shoulders forward. Get up for five minutes every hour.^7,1,2,9,4

When should I worry about shoulder pain from computer work?

When it gets worse or doesn't ease after 2 weeks, see a doctor, the NHS says. Chest pain that spreads to your arm, neck or jaw is an emergency: call 911 in the US, 999 in the UK, or your local emergency number.^9,10
