长期低头看手机对背部损伤严重

#研究分享#【长期低头看手机对背部损伤严重】《外科技术》杂志发表最新研究称:头部倾斜60度看手机,就像在颈部施加五六十斤的压力。根据计算机模型演示,头部前倾角度越大,颈部受压力也越大。并建议人们在使用手机或电脑时,一定要注意头部保持直立的姿势,最好能够平视屏幕,并经常舒展身体,保持活动。

Staring At Your Phone All Day Is Killing Your Back, Study Finds

Put down your phone and pick up your head. Texting might be ruining your back.

When you tilt your head forward 60 degrees to look at your phone, you're putting 60 pounds of pressure on your neck, according to a new study by New York spine surgeon Kenneth Hansraj. Hansraj's study was just published in Surgical Technology International's 25th edition.

As you bend your head down to look at the phone in your hands, the pressure on your neck gets stronger and stronger, as shown in Hansraj's illustration below:

Hansraj created a model of the spine via computer-aided design, and bent the head 0 degrees, 15 degrees, 30 degrees, 45 degrees and 90 degrees, all while measuring the force on the spine. "It's a very sophisticated assessment of the stresses that are borne by the neck when the head is in various positions," Hansraj said in a phone interview with The Huffington Post.

"This is one assessment just based on bringing the neck forward," Hansraj said. Different things could happen to your neck if you're bending it forward and to the side, he noted.

So what should you do to protect yourself?

"We recommend that people should continue to enjoy their smart devices, but that they pay specific attention to where their head is in space," Hansraj said. "You want to be careful that your head is straight up with you're using a smart device."

Hansraj also pointed out another common spinal issue: sitting at a desk all day. For office workers who spend their days staring at a screen, some options for alleviating back pain include making sure you stretch, taking frequent breaks to walk around, and positioning your monitor so that you're looking at it straight on.
