Almost all of us have been told at some point to sit up straight or stand up straight. In modern Western societies, many people spend hours each day sitting at desks, leaning over laptops, or scrolling on phones and tablets. It is common to see people hunched forward for prolonged periods, both at work and at home.
This raises an important question. Is poor posture actually bad for you? More specifically, does poor posture cause back pain, and will sitting up perfectly straight prevent it?
The answer is more nuanced than many people think.
Does poor posture cause back pain?
Research, including work from Curtin University’s School of Physiotherapy in Western Australia, suggests that posture itself is not necessarily the primary cause of back pain.
The key issue is not posture alone. It is the lack of movement.
Even individuals with excellent posture who can sit upright in what appears to be perfect alignment may still experience discomfort if they remain in the same position for long periods without moving. The human body is designed for movement. When we sustain any posture for too long, tissues can become sensitised and uncomfortable.
In other words, it is not simply “bad posture” that causes problems. It is sustained posture without regular variation.

The effects of prolonged sitting and sustained posture
While posture alone may not directly cause pain, prolonged sitting and sustained positions are associated with a range of musculoskeletal concerns.
Neck and back pain
Remaining in the same position for extended periods can lead to muscle fatigue, joint stiffness and discomfort. Sustained positions are commonly linked with neck and back pain, particularly when movement breaks are limited.
Headaches
Headaches can originate from the neck. Prolonged sustained posture, particularly when combined with screen use, may contribute to tension related headaches in some individuals.
Shoulder strain
Pain between the shoulder blades and around the shoulders is common in people who spend long hours in fixed seated positions.
Mood and fatigue
Research suggests that sustained poor posture may negatively influence mood and increase feelings of fatigue. Conversely, upright and varied movement patterns are associated with improved alertness and energy levels.
The message is clear. The body thrives on regular movement and position changes.
Does “good” posture prevent back pain?
It is important to clarify an emerging understanding in healthcare.
Having so called “good” posture does not guarantee freedom from back pain. Equally, having “bad” posture does not automatically cause pain.
Pain is complex. It is influenced by many factors including activity levels, stress, sleep, general health and previous injury. Posture is only one small piece of a much bigger picture.
Rather than aiming for rigid perfection, it is more helpful to aim for regular movement and comfortable variability.

How to reduce the impact of sustained posture
The goal is not to sit perfectly all day. The goal is to move more often.
Stand up regularly
Prolonged sitting is associated with a range of health concerns. Stand up and move regularly throughout the day, even if only for a minute or two.
Be mindful of movement, not perfection
Pay attention to how long you remain in one position. Change your posture frequently at work and at home. Small adjustments throughout the day make a difference.
Adjust your workspace
Ensure your desk setup supports comfortable working positions. Your screen should be approximately at eye level, your chair should support your lower back, and your feet should rest flat on the floor. However, even the best setup does not replace regular movement.
Exercise regularly
General exercise supports spinal health and overall wellbeing. This may include walking, running, swimming, cycling, strength training or any activity you enjoy and can maintain consistently.
Strengthen your trunk muscles
Targeted strengthening of trunk and hip muscles can support spinal control and endurance. Exercises such as planks, bridges and back extensions can be beneficial when performed correctly.
Clinical Pilates can also improve posture awareness, control and endurance.
Take movement breaks
Joints and muscles are designed to move. Schedule short movement breaks during the day to stretch, walk or change position.
Seek professional guidance
If you are experiencing persistent neck or back pain, consulting a physiotherapist can be helpful. A physiotherapist can assess your movement patterns, provide personalised exercises and guide you in building strength and resilience.

Final thoughts
Poor posture alone is unlikely to be the sole cause of back pain. Likewise, perfect posture does not guarantee protection from it.
What matters most is regular movement, strength, and variability throughout the day.
