For millions of people, the workday looks something like this: sit down, open the laptop, answer emails, attend virtual meetings, work for several hours—and suddenly realize you have barely moved.
By the end of the day, your neck feels tight, your shoulders are tense, or your lower back is aching.
Coincidence? Probably not.
Research increasingly suggests that long periods of computer work—especially when combined with static or awkward postures and too few movement breaks—are associated with neck, shoulder, and lower-back complaints. However, the science also tells us that the problem is more complicated than simply saying, “Sitting is bad.”
What Does the Research Say About Sitting and Back Pain?
A 2025 scoping review examined 22 studies involving 7,814 office workers and looked specifically at sitting time, sitting posture, sitting behavior, and low-back pain.
The researchers found that longer sitting time, poor sitting posture, fewer breaks, and more static sitting were associated with low-back pain. Interestingly, the strongest evidence involved sitting behavior—how people sit and how often they change position—rather than sitting time alone.
A separate systematic review and meta-analysis of 49 studies also reported an association between sedentary behavior and low-back pain. Among adults, prolonged sitting was associated with increased odds of low-back pain.
This distinction is important.
Your body isn’t necessarily designed to maintain one “perfect” posture all day. It is designed to move.
Computer Time and Neck Pain
The neck presents a similar problem.
When working at a computer, many people gradually move away from a neutral position. The head moves forward, the shoulders round, and the upper back becomes more flexed.
This can be especially noticeable when the monitor is too low, too high, too far away, or positioned off to one side.
A systematic review investigating neck pain among computer users found that workplace factors became particularly important when increased duration of computer tasks was combined with ergonomic demands.
More recent research has also examined how the duration of computer use relates to neck, arm, and shoulder complaints. A 2026 systematic review and meta-analysis of prospective studies found that computer or mouse use exceeding four hours per day was associated with an increased risk of arm, neck, and shoulder complaints, with a pooled relative risk of approximately 1.25.
That doesn’t mean everyone who works at a computer four hours a day will develop neck pain. It means prolonged exposure appears to be one factor that can contribute to the overall risk.
Why Can Hours at a Computer Become a Problem?
The human body handles movement extremely well. What it often handles less effectively is remaining in the same position for hours at a time.
The U.S. Occupational Safety and Health Administration (OSHA) notes that maintaining static postures while viewing a monitor for prolonged periods without breaks can fatigue the muscles of the neck and shoulders. OSHA recommends changing working positions frequently rather than remaining in one position throughout the day.
Several things may happen during a long computer session:
Muscles remain active for prolonged periods.
Even though sitting doesn’t feel physically demanding, muscles still have to support your head, neck, shoulders, and trunk. Holding one position for hours can contribute to muscular fatigue.
Your posture gradually changes.
Few people sit at 4:00 p.m. exactly the way they did at 8:00 a.m. As fatigue develops, you may begin leaning toward the screen, rounding your shoulders, slouching, or shifting your head forward.
Movement decreases.
Healthy joints and muscles benefit from regular movement and changes in position. Long uninterrupted work sessions remove much of that natural movement from the day.
Your workstation can magnify the problem.
OSHA specifically identifies monitor position as an important consideration. A monitor that is too high or low can place the head, neck, shoulders, and back in awkward positions, while a monitor positioned off-center can require prolonged neck rotation.
The Best Posture May Be Your Next Posture
People frequently ask, “What is the perfect sitting posture?”
Good ergonomics certainly matter. But there is another principle that may be even more useful:
Don’t try to hold one position all day—even if it’s a good position.
OSHA recommends frequently changing working positions, making small adjustments to your chair or backrest, standing periodically, walking for a few minutes, and performing some work tasks while standing when practical.
Think of posture as something dynamic rather than static.
Sit.
Change position.
Stand.
Walk.
Stretch.
Then sit again.
Your goal isn’t necessarily to sit perfectly for eight hours. Your goal is to avoid spending eight hours essentially frozen in one position.
5 Things Computer Workers Can Do Today
1. Get up regularly.
Build movement into your workday. Stand, walk, stretch, or simply change positions periodically rather than waiting until your neck or back hurts.
2. Bring the monitor to you.
Don’t spend the day bringing your head toward your monitor. Position your screen so you can comfortably look at it without continually leaning forward, looking dramatically upward or downward, or rotating your neck.
3. Keep frequently used items within comfortable reach.
Your keyboard, mouse, phone, and other commonly used items should not require repeated reaching or twisting.
4. Use your chair for support.
Adjust your chair so your back is supported and your feet are comfortably supported by the floor or a footrest when necessary.
5. Make movement part of your work—not something you do only after work.
A workout at the end of the day is valuable, but it doesn’t change the fact that your body may have spent the previous eight hours in a relatively static position. Look for opportunities to walk during phone calls, stand during meetings, change positions, or take short movement breaks.
When Neck or Back Pain Keeps Returning
Occasional stiffness after a long day at the computer is one thing. Pain that continually returns, becomes more intense, limits your movement, or begins interfering with work, sleep, exercise, or everyday activities deserves attention.
At Lakewoods Chiropractic in Forest Lake, Minnesota, we frequently work with people whose jobs require them to spend much of their day sitting or working at a computer.
Our goal isn’t simply to look at where it hurts. We want to consider the bigger picture—including spinal and joint function, movement, posture, workplace habits, ergonomics, and the physical stresses you’re placing on your body every day.
Because sometimes the question isn’t simply:
“How is your posture?”
A better question may be:
“How long have you been in that posture?”
