Posture is your body’s position while you’re sitting or standing. It’s how your spine is inline with your head, shoulders, hips, and limbs. How can you determine if your posture is good or bad? Good posture doesn’t put stress on your body and helps you maintain balance. Bad posture can easily lead to you getting hurt and experiencing long-term pain. Here are a few different examples of bad posture:
【Forward Head Posture】
With forward head posture, people’s ears are in front of their shoulders instead of in line with them. Commonly, people develop this problem by hunching over a computer or phone.
【Kyphosis】
Rounded shoulders and a rounded upper back indicate kyphosis. This often happens when our bones get weaker with age.
【Swayback】
With swayback, a person’s hips are too far forward. This can happen if you constantly sit, which tightens your back muscles. It also makes your stomach and glute muscles weaker.
【Flatback】
Flatback is a condition in which the lower spine is not curved enough. This can make standing up for long periods painful.
姿势指的是你坐着或站着时身体的位置，也就是你的脊椎与头部、肩膀、臀部和四肢对齐的位置。如何确定自己的姿势好坏呢？良好的姿势不会给身体带来压力，并有助于维持平衡。不良的姿势则容易导致受伤和长期疼痛。以下是几种不良姿势的例子：
【头颈前倾】
头颈前倾时，人的耳朵会位于肩膀的前方，而不是与肩膀成一直线。人们通常因弓着身子看计算机或手机时出现此问题。
【驼背；脊柱后弯症】
圆肩和圆背是驼背的征兆。这经常随着年龄增长和骨骼变脆弱而发生。
【腰椎过度前弯】
腰椎过度前弯的人臀部会过于前倾。如果你经常坐着，久坐会使背部肌肉紧绷，就可能会发生腰椎过度前弯的状况。它还会使腹部与臀部肌力减退。
【平背】
平背是指下脊椎不够弯曲的一种疾病。这会使长时间站立令人感到疼痛。
