低头族:千万不要让脖子挂着“西瓜”前行

2016-07-11 佚名 健康界

以成人的头部重量为8公斤计算,当我们低头15°时,颈椎所能承受的压力为垂直时的2倍。当头部低至60°时,颈椎承受的重量为34.4公斤,相当于给颈椎挂上了两个“大西瓜”。 随着电子科技的发展,越来越多的人们患上了“电子设备依赖症“,不管是在地铁上,公交车上,随时都能看到低头看手机、刷微信朋友圈、玩手游、刷微博的”低头一族“。可是你知道吗?低着头前行,无异于脖子上挂着两个“大西瓜”前行!

随着电子科技的发展,越来越多的人们患上了“电子设备依赖症“,不管是在地铁上,公交车上,随时都能看到低头看手机、刷微信朋友圈、玩手游、刷微博的”低头一族“。可是你知道吗?低着头前行,无异于脖子上挂着两个“大西瓜”前行!



我们人类的颈椎一共有7节,除外第一环椎和第二枢椎椎体之间没有椎间盘连接,从第二节颈椎到第七节颈椎都有椎间盘连接。一直低头,椎体和椎间盘之间形成了很大的剪切力量。


从一份来自美国纽约脊柱手术及康复中心发表报告指出:当人身体直立时,颈椎所能承受的只是头部自身的重量;而低头玩手机,会让颈椎承受60磅(约27公斤)的重压。以成人的头部重量为8公斤计算,当我们低头15°时,颈椎所能承受的压力为垂直时的2倍。当头部低至60°时,颈椎承受的重量为34.4公斤,相当于给颈椎挂上了两个“大西瓜”。而另一份数据显示,低头族的头部每往前移动一英寸,颈部承担的剪切力量就要大一倍。所以低头伴随着头前移,整个脑袋对于颈部的作用力要数倍于垂直直立的作用力。换句话说,低头玩手机前行,就相当于挂着两个“大西瓜”前行!

长时间的低头前行,除了诱发出颈椎病,还能诱发一系列的颈肩症状,我们统称为上交叉综合症。那什么是上交叉综合症呢?上交叉综合症是指由于长时间低头伏案造成前胸和后背等部位肌肉不平衡,形成头部前倾、含胸、圆肩、驼背、肩胛骨耸起等一系列形体的变化,并进而导致颈肩部肌肉紧张酸痛、头痛头晕、手臂麻木、呼吸不畅、心慌胸闷甚至便秘等各种症状。

古人云:站如松、坐如钟。正常时候是无论在坐位还是在站位,都应该是挺胸颔首,双肩打开的姿势。而不良的上半身姿势如长时间低头伏案,含胸驼背,日久因胸前下部和颈背后上部肌肉紧张和缩短,背后下部和颈前上部肌肉被拉长及软弱,从而形成了一种典型的交叉症状。加剧了对于我们颈椎健康的损害!

除了减少低头前行玩手机,还要保持正确的站姿和坐姿。即头向上顶、下颌微收、肩部打开、挺胸收腹。让身体开始学习、适应新的姿势,可以逐渐提高生活质量。

当然,在传统推拿功法中,还有一种针对颈椎上交叉综合症的功法锻炼可以帮助到“低头一族”。那就是传统推拿功法中的“与项争力”。该方法的具体操作如下:站姿或者坐姿过程中,将我们的两只手放到颈后,双肘撑开,双手用适当的力向前拉颈部,以不酸痛为度。头部则用力向后仰后伸,保持静止性对抗用力。每次坚持30秒,每天做10组。通过自我手臂和颈部的力量对抗,能锻炼颈部肌肉,从而加强颈部的核心肌群肌力及其稳定性。同时缓解颈前肌群短缩无力和后背肌群拉长无力的情况。



坚持正确的站立坐姿,拒绝做一个低头族!每天练习“与项争力”,千万不要让脖子挂着两个大西瓜前行!
