Which statement about proper posture is true?

The statement that good posture can reduce the risk of eye strain is accurate. Maintaining proper posture helps ensure that the body is aligned correctly, which can positively affect how the head and neck are positioned relative to screens or reading materials. When the head is in an optimal position, it allows for a more natural line of sight, reducing strain on the eyes, neck, and back. This is particularly relevant in environments where individuals spend extended time in front of computers or focusing on documents. Proper posture minimizes any additional stress that could contribute to discomfort or fatigue, making it easier to maintain focus and productivity over time.

On the other hand, while some may think that good posture can lead to back pain, this is usually a misconception since poor posture is often the leading cause of such pain. Good posture, when consistently maintained, supports the spine and can help prevent pain. The idea that good posture requires constant adjustment can be true in certain contexts but it is more about developing a habit of good posture rather than needing to continuously adjust it. Lastly, the statement regarding the unimportance of good posture for productivity contradicts a significant body of research that links good ergonomics and posture with enhanced work performance and efficiency.
