Lower Back Pain From Sitting: What’s Actually Happening
Lower back pain from sitting is one of the most common complaints we see, especially in people who spend long hours at a desk or in the car. If you're dealing with persistent symptoms, our Back Pain Physio in Varsity Lakes page explains how we assess and manage lower back pain in more detail.
Many people assume their posture is the main issue.
But the reality is usually more about how long you stay in one position, not just the position itself.
Why Sitting Causes Lower Back Pain
Sitting places the spine in a relatively fixed position for extended periods.
Over time, this can lead to:
Reduced movement variability
Increased muscle stiffness
Reduced blood flow
Decreased tolerance to load
Your body is designed to move. When movement is limited for long periods, even low-load positions can become uncomfortable or painful.
Is It Just “Bad Posture”?
Not exactly.
While posture can play a role, there is no single “perfect posture” that prevents pain.
The bigger issue is:
Staying in one position too long
Not having enough movement throughout the day
Reduced strength and capacity to tolerate sitting
This is why simply trying to “sit up straight” doesn’t usually fix the problem.
Why Pain Builds Throughout The Day
Lower back pain from sitting often:
Starts mild in the morning
Gradually increases during the day
Feels worse after long periods without movement
This happens because tissues become less tolerant when they are held in the same position for too long.
Over time, sensitivity increases and even normal sitting can become uncomfortable.
Why Rest Doesn’t Fix It
Many people try to solve sitting-related back pain by:
Resting more
Avoiding activity
Stretching briefly
While this may provide short-term relief, it does not improve your ability to tolerate sitting or movement in the long term. This is where Exercise-Based Rehabilitation becomes important.
What Actually Helps
Improving lower back pain from sitting usually involves:
Increasing movement throughout the day
Building strength and endurance
Improving tolerance to different positions
Gradually reintroducing load
This is where Injury Rehabilitation helps address the underlying issue, not just the symptoms.
Simple Strategies To Reduce Pain
You don’t need a perfect setup to improve symptoms.
Start with:
Standing up every 30 to 60 minutes
Changing positions regularly
Taking short walking breaks
Avoid staying in one posture all day
Movement variety is more important than perfect posture.
When Pain Keeps Coming Back
If lower back pain continues despite making changes, it may indicate:
Reduced strength and endurance
Poor load tolerance
Sensitivity to sustained positions
If symptoms have been ongoing for several months, a Chronic Pain Physiotherapy approach may help gradually rebuild confidence and tolerance.
When To Seek Help
Consider booking an assessment if:
Pain persists beyond a few weeks
Symptoms worsen over time
Sitting becomes increasingly uncomfortable
You are unsure how to manage it
A physiotherapy assessment helps identify what is driving your symptoms and how to address them properly.
The Goal: Build A Back That Tolerates Sitting
Sitting is not the problem.
A lack of movement and capacity is.
With the right approach, most people can sit comfortably, stay active, and reduce recurring pain.
If you want clear direction and a structured plan, booking a physiotherapy appointment is the most effective next step.
