Which Puts Less Pressure on the Lumbar Spine: Sedan or SUV?
1 Answers
SUVs exert less pressure on the lumbar spine and cervical spine compared to sedans. This is because sedan seats are relatively low, causing the driver to sink into the seat. To achieve comfort, one might recline while driving, which requires extending the neck forward to see the road, thereby increasing the load on the neck. The correct sitting posture should resemble that of buses, high-speed trains, or airplanes, which minimizes lumbar spine pressure and is suitable for long-distance travel. From this perspective, SUVs more closely approximate this ideal posture. Differences between sedans and SUVs: 1. Chassis: Sedans have a lower chassis and, consequently, a lower center of gravity, resulting in smaller vehicle tilt angles during turns. SUVs have a higher chassis, enabling them to adapt to various road conditions. 2. Seat Comfort: SUVs tend to favor a sporty style, often featuring firmer seat designs. Sedans prioritize passenger comfort, typically offering softer seats. 3. Fuel Consumption: SUVs are generally designed with off-road capabilities in mind, making them heavier than sedans and equipped with larger engine displacements, leading to higher fuel consumption in comparison.
