What role does posture play in typing efficiency?

Posture significantly impacts typing efficiency, particularly by influencing both physical comfort and overall performance. When an individual maintains proper posture while typing, such as keeping a straight back, relaxed shoulders, and appropriately positioned hands, it helps prevent strain and fatigue. This is vital for maintaining long periods of typing with optimal performance. If the posture is incorrect, it can lead to muscle fatigue, discomfort, or even repetitive strain injuries, which can adversely affect typing speed and accuracy.

Effectively, good posture ensures that the typist can sustain their focus and energy levels, resulting in better typing output overall. In contrast, poor posture can create distractions due to discomfort, making it challenging to type efficiently or maintain concentration on the task at hand. Thus, choice B accurately captures the importance of posture in fostering an environment that facilitates both typing speed and overall performance.
