Maintaining the natural S-curve in your back helps to reduce what risk?

• A. Back strain
• B. Neck strain
• C. Eye strain
• D. Leg cramp

Answer: (A)

Keeping the spine in its natural S-shaped curve reduces stress on the back by evenly distributing load and minimizing excessive bending. When you slouch or lean forward, the lower back bears more strain as muscles and ligaments work harder to keep the torso upright, increasing the risk of back strain. Maintaining neutral alignment—hips back in the chair, lumbar support, feet flat, and the head balanced over the spine—helps keep the load on the back low, especially during long periods of sitting or standing. This is why the risk most directly reduced by preserving the natural back curve is back strain. Other issues like neck strain, eye strain, or leg cramps come from different factors such as head position, screen distance, or leg circulation.
