怎样用电脑不伤颈椎



电脑给人类的颈椎带来伤害已经是不争的事实了,可是电脑是太重要的工具,现代人几
乎一天都离不开它。那么,我们必须解决的一个问题是,怎么使用电脑不伤、少伤颈椎?

这个,当然是见仁见智了,说法很多。比如附图所示。

看着好像很有道理,但是你一试便知,它没用。

以前,我曾经对这个问题,做过很多的探索,什么坐笔直啦,买那种笔直靠背的折叠椅
啦,实践证明都无效。

首先,我们先看看,用电脑是怎么伤的颈椎。我个人的看法,主要是两个力量:

    1. 头的无意识前伸,带动颈椎的前伸;
    2. 肘部悬空,没有支撑,所带来的肩部紧张。

最后,我发现,还是这一招最管用:胸前紧贴桌子,后背紧靠椅背,让自己“紧夹”在
桌子和椅子背中间,不留空隙。

这个办法,对头的前伸和肘部的悬空都解决的比较好,大家可以一试。
