Lower Back Pain and Sitting: Causes, Prevention, and Effective Relief Strategies

Sitting for long periods has become a normal part of modern life. Whether you work at a desk, drive for extended hours, study, or spend time using digital devices, prolonged sitting can take a toll on your body—especially your lower back. Lower back pain is one of the leading causes of discomfort and disability worldwide, and a sedentary lifestyle is a major contributing factor.

Many people believe that sitting is a resting position for the body. However, prolonged sitting can place significant stress on the spine, weaken supporting muscles, and lead to stiffness and pain. Understanding how sitting affects your lower back and learning effective prevention strategies can help you maintain a healthy spine and improve your overall quality of life.

What Is Lower Back Pain?

Lower back pain refers to pain, stiffness, or discomfort in the lumbar region, which is the area located between the ribs and pelvis. The pain may range from mild to severe and can occur suddenly or develop gradually over time.

Types of Lower Back Pain
