Does Prolonged Sitting at Work Cause Lower Back Pain?

In today’s modern lifestyle, many people don’t realise just how much time they spend sitting. From commuting to work, sitting at a desk all day, relaxing on the couch in the evening, or enjoying long brunches on the weekend, prolonged sitting has become the norm.

At The Physio Spot Camden & Harrington Park, we regularly see patients with lower back pain caused or aggravated by long hours of sitting at work. In this article, we explore how prolonged sitting affects your spine, why it can lead to lower back pain (and sciatica), and what you can do to prevent or manage it.


Health Risks of Prolonged Sitting

Prolonged sitting has been described by some health experts as “the new smoking” due to its long-term impact on health. While this may sound extreme, research consistently shows that sitting for long periods can significantly affect your spine, muscles, and nervous system. Studies suggest that up to 70% of adults sit for six hours or more per day, most commonly at work. Even people who exercise regularly can still experience negative health effects if the majority of their day is spent seated.

Studies suggest that up to 70% of adults sit for six hours or more per day, most commonly at work. Even people who exercise regularly can still experience negative health effects if the majority of their day is spent seated.
Health risks associated with prolonged sitting include:

  • Chronic lower back pain
  • Sciatica and nerve irritation
  • Poor posture and spinal stiffness
  • Reduced circulation
  • Increased risk of heart disease and type 2 diabetes

Regular movement helps reduce these risks, but prolonged sitting without breaks remains a major contributor to musculoskeletal pain.


How Prolonged Sitting Affects the Lower Back

When you sit, the weight of your upper body is transferred directly through your lower spine. Over time, this increases compression on the spinal discs and surrounding structures.
Poor posture, slouching, unsupported chairs, and long periods without movement can:

  • Increase pressure on spinal discs
  • Tighten hip flexors and hamstrings
  • Weaken core and glute muscles
  • Irritate spinal nerves

This combination often results in lower back pain, stiffness, and in some cases pain that travels into the hips, buttocks, or legs.
If you already have a history of back issues, prolonged sitting can significantly worsen symptoms.


Can Prolonged Sitting Cause Sciatica?

Yes, prolonged sitting can contribute to sciatica.
Sciatica occurs when the sciatic nerve is irritated or compressed, commonly due to disc bulges, spinal joint irritation, or tight muscles around the pelvis. Sitting for long periods increases pressure through the lower spine and can aggravate these structures.

Common causes of sciatica include:

  • Prolonged sitting (especially at work)
  • Disc bulges or herniations
  • Poor posture
  • Bone spurs
  • Pinched nerves

Less common causes include diabetes, nerve injuries, pelvic trauma, or previous fractures. People at higher risk include desk workers, drivers, those who do heavy lifting, people who wear high heels regularly, and individuals with reduced physical activity.


Symptoms of Lower Back Pain and Sciatica

Symptoms can vary from mild discomfort to severe pain and may include:

  • Lower back pain (often one-sided)
  • Pain in the buttocks or down the leg
  • Sharp or shooting pain when sitting
  • Pain with coughing or sneezing
  • Numbness or tingling
  • Muscle weakness

Early treatment is important to prevent symptoms from becoming chronic.


FAQs: Prolonged Sitting & Lower Back Pain

Does prolonged sitting at work cause lower back pain?
Yes. Sitting for long periods places sustained pressure on your lower spine, especially if posture and workstation setup are poor.
Does sitting make lower back pain worse?
Often, yes. Remaining in one position for too long can increase stiffness, muscle tightness, and nerve irritation.
How should I sit to reduce lower back pain?

  • Change positions every 20–30 minutes
  • Use lumbar (lower back) support
  • Keep feet flat and hips slightly higher than knees
  • Avoid soft, unsupportive chairs
  • Stand up and move regularly

Using a rolled towel or lumbar cushion can significantly reduce spinal strain.


Can Sitting Too Long Cause Nerve Pain?

Yes. Prolonged compression of the spine can irritate nerves over time. While sciatica is one form of nerve pain, prolonged sitting can also contribute to other spinal and muscular conditions that cause pain, weakness, or altered sensation.

The human body is designed to move — prolonged inactivity often worsens back pain rather
than relieving it.


How Physiotherapy Can Help

The most effective way to manage lower back pain caused by prolonged sitting is with physiotherapy.
