Cellphones and computers are just about everywhere on earth. People hunched over these devices and it causes more harm than they realize. When Dr. Lushantha Gunasekera began feeling pain, he thought he needed strength training. “It was mainly pain on, in my upper back and, and neck, and shoulder area and it was just on the one side.” A fitness trainer at the Orlando Health gym knew the pain was due to poor posture. “Internally rotated shoulders, rounded back. Head is down. Neck is down.” Melendez worked with Gunasekera on his posture. All that hunching or jutting your head forward to look at a screen compresses your neck muscles. This causes fatigue, muscle tension and headaches.

手机和电脑在全世界几乎无处不在。人们在这些设备前弓着腰,造成的伤害比人们意识到的要多。当 Lushantha Gunasekera 医生开始感到疼痛时,他认为自己需要进行力量训练。“主要是我的上背部、脖子和肩膀部位疼痛,只是一侧疼痛。”奥兰多健身中心的一位健身教练知道这种疼痛是由于不良的姿势造成的。“肩部内旋,向后转圈。头下来。脖子向下。” Melendez 和 Gunasekera 一起研究运动姿势。所有那些弯腰驼背或把头向前伸看屏幕的动作都会挤压颈部肌肉。这会导致疲劳、肌肉紧张和头痛。

It can also injure the vertebra in your back, but it can be prevented and corrected. “You’ll be surprised with strengthening your core into impartial corrective exercises can do for your body.” Melendez says even being slightly unaligned can cause major strain, but researchers at Orlando Health found that less than half the Americans they surveyed seem to care. Even a slight misalignment can cause major strain. For every two and a half centimeters your head moves in front of your body, four and a half kilograms of pressure is added to your shoulders. If you move your head forward 100 millimetres, the way imbalance is even greater. “That’s the equivalent to having a child sit on your shoulders.” Gunasekera says changing his posture made a huge difference. “Discussing what I was doing incorrectly. Doing more core exercises, more mobility. Being cognizant every day about my posture. It’s really helped out, and now I don’t have pain there anymore.” Melendez says while you’re using a computer or cell phone, make sure your eye level with the screen. If you can, take frequent breaks and work on your posture.

它还会损伤背部的脊椎,但可以预防和纠正。“你会惊讶地发现,加强核心部位到全面转换的纠正练习可以对身体起到帮助作用。” Melendez 说,即使是轻微的不一致也会造成很大的压力,但是奥兰多健康中心的研究人员发现,他们调查的美国人中,只有不到一半的人似乎在意这些。即使是轻微的错位也会导致大的张力。你的头每向前移动2.5厘米,你的肩膀就会承受4.5公斤的压力。如果你把头向前移动100毫米,这种不平衡甚至更大。“讨论我做错了什么。多做核心运动,多活动。每天都要注意自己的姿势。这真的很有帮助,现在我不再感到疼痛了。” Melendez说,当你使用电脑或手机时,要确保眼睛与屏幕水平。如果可以的话,经常休息,改善姿势。
