Posture is the position that your body maintains while standing, sitting, or lying down. Most experts would agree that "good" posture reduces the stress on your spine by balancing the load placed upon the muscles and ligaments that support it.
Good posture is essential because it helps you align your bones and joints properly. This helps reduce the wear and tear on your joints and can decrease the strain on the ligaments that support your spine. New research also indicates that maintaining a good or balanced posture can help you use your muscles more efficiently and prevent fatigue.
To prevent back pain, your best posture may be one of motion. If you sit in one position too long, small nerves will detect the pressure and send messages to your brain, indicating that you're uncomfortable—which is your prompt to move!
Researchers believe these "uncomfortable" signals before pain are our body's way of telling us to move or change positions. A standing desk is one of the best strategies to reduce neck and lower back pain associated with sitting.
One of the best ways to improve your posture is to not stay in a single position for too long. Changing your position throughout the day, using a lumbar support when seated, and even using a standing desk are all ways that you can reduce fatigue and pain.
