电脑前一坐就是8小时，手机充着电也要玩……很多人一低头就是一整天，但就是这个常见的动作，让19岁的年轻小伙差点高位瘫痪！
19岁小伙长时间低头
差点瘫痪
阿东（化名）是福建泉州某大学的学生，暑假期间，他在一家餐饮店兼职，每天连续低头洗碗、擦桌子4小时以上。回宿舍后，他又趴在床上打游戏、刷短视频2小时到3小时。
A Dong (pseudonym), 19-year-old college student in Quanzhou, Fujian province, spent his summer working part-time in a restaurant, where he kept his head down for hours washing dishes and wiping tables. Back in his dormitory, he continued the routine, spending several more hours gaming and scrolling on his phone.
一天，阿东感到身体异常，手脚及颈后背常有麻木疼痛感。于是，他前往医院做CT检查，但未发现异常。几天后，他的麻木感加剧，甚至出现双下肢无法动弹、失去感觉的状况。
经检查，医生发现阿东颈椎C4-T1椎管内存在巨大占位性病变，压迫脊髓。此时的阿东胸部以下均无知觉，双上肢肌力明显减弱。
Soon, he developed numbness and pain in his limbs and neck. Although an initial CT scan found no abnormalities, his condition rapidly deteriorated, and he suddenly lost the ability to move both legs.
Further examinations revealed a large blood clot pressing on his spinal cord between the C4 and T1 vertebrae.
手术中医生发现，阿东颈椎椎管内硬膜外存在巨大凝血块压迫脊髓。医生推测，可能是阿东的椎管内硬膜外小血管存在异常，如血管畸形等，在长期低头工作等外因作用下，使血管破裂出血形成血肿，导致压迫脊髓，进而造成他出现高位瘫痪症状。
Doctors believed abnormal vessels in the spinal canal — aggravated by long hours of forward head posture — had ruptured, forming a hematoma.
术后，阿东的肢体瘫痪症状有所缓解，四肢肌力恢复，19岁的他眼泪止不住地往下掉，“再晚几个小时，我这辈子可能就站不起来了。”
Emergency surgery relieved the pressure, and his mobility gradually returned. "If I had come just a few hours later," he said, "I might never have stood again."
长时间低头易肌肉疲劳
严重者甚至会瘫痪
其实，类似阿东的情况不在少数。
医生介绍，“低头族”越来越多，颈椎病的发病率也显著增加。
调查显示，我国20岁至40岁青壮年颈椎病患病率高达59.1%。在青壮年中出现的颈椎反弓、颈椎病、腰椎间盘突出，与久坐、低头用手机直接相关。而低头玩手机会让颈椎承受约27公斤的重压，比一个7岁小孩还重。
Research shows that 59.1 percent of Chinese adults aged 20 to 40 suffer from cervical spondylosis. Looking down at a phone at a 60-degree angle can place about 27 kilograms of pressure on the cervical spine — the equivalent of a 7-year-old child sitting on one's neck.
哪些姿势会伤害脊柱？
Experts also point to other everyday habits that harm the spine: long hours of sitting, especially when leaning forward; bending at the waist to lift heavy objects; crossing legs; slouching on sofas; and carrying one-shoulder bags. Over time, these behaviors can cause chronic pain or structural damage.
如何预防脊柱损伤？
To protect spinal health, doctors recommend strengthening support muscles through exercises such as planks and sit-ups, maintaining proper posture, and adjusting workspaces with lumbar support and computer screens slightly above eye level. Just as important, they advise taking regular breaks — standing and moving for 10 minutes after every 40 to 60 minutes of sitting.
