Your upper body slouches forward

你的上半身前倾

You've probably seen those charts about how to sit properly -- shoulders relaxed, eyes level with the screen, arms parallel to the floor, back straight. But as your to-do list consumes the day, demands like managing your inbox and dealing with your boss eventually cause a breakdown in your posture. "You're slouching whether you know it or not. When you slouch while sitting, your head is pulled down and forward by gravity. Your spine will start to curve and your body will experience pain," Vernikos noted. "If you keep your back straight and you think of gravity as a force that pulls in one direction, downward, like a vertical rod, you can align yourself to this vertical and spare your body from pain."

你也许看过保持正确坐姿的图片，肩膀放松，视线与屏幕保水平，手臂与地面平行，背部挺直。但是一天的工作任务，周旋在你的个人事务和处理老板事物之间，最终正确的坐姿就变样了。“不管你是否察觉得到，你的身体就开始耷拉下来，由于重力的原因你的头就开始往下并前倾，脊柱就会相应弯曲，身体就会开始不适。但是你如果保持背部挺直，想象重力是一股往下的拉力，就像一个垂直杆，你就可以调整你的身体，疼痛就会消失。” Vernikos建议道。
