Why does my back hurt after sitting for a long time?
Direct answerBack pain from sitting usually comes from going hours without getting up, a poorly set-up workstation (low screen, unsupportive chair, feet not supported), and limited strength and mobility in your trunk and hips. The first step is to get up and move for a minute or two every 30 to 45 minutes.
How it shows up
Your lower or mid back gets sore and stiff throughout the day, gets worse by the end of the workday, and eases when you stand up or move around.
Most likely root causes
- Too much time stillStaying in the same position for hours keeps loading the same structures, whether or not your posture is 'perfect.'
- Poor workstation setupA screen below eye level, a laptop flat on the desk, a chair that's too high or low, and unsupported feet encourage you to hunch over.
- Weak core and hipsUnderused abdominal, glute, and back muscles tire quickly and leave your spine without support.
- Inactivity outside workSitting at work, in the car, and on the couch adds up to many hours and reduces hip mobility.
Quick self-check
- Do you go more than an hour at a time without getting up?
- Is the top of your screen below eye level?
- Do your feet dangle or lack firm support on the floor?
- Do you do strength exercises less than twice a week?
If you answered yes to two or more, start with that cause.
First step today
Set a reminder today to get up every 40 minutes, walk a bit, and stretch your trunk for one to two minutes.
30-day plan
- Week 1: start taking active breaks and adjust your screen height, chair height, and foot support.
- Weeks 2 and 3: add 10 minutes of simple core, glute, and hip mobility exercises every other day.
- Week 4: increase your daily walking and assess which changes did the most to reduce pain at the end of the day.
When to seek professional help
See a doctor or physical therapist if the pain spreads down your legs, or comes with tingling, weakness, changes in bladder control, or gets worse even at rest.
Frequently asked questions
- Is there a correct way to sit?
- More important than an ideal posture is changing positions and getting up often. Your best posture is your next one.
- Will an expensive chair fix the pain?
- It helps if it's properly adjusted, but it doesn't replace breaks, movement, and strengthening.
