当你坐上个一整天,知道你的臀部和小腿会发生什么变化么?什么变化都不会发生,除了上面的肌肉量逐渐减少。当准备回家时,你的腿再次负荷整个身体的重量时,会导致,疼痛,走路摇摆无力。“其实这与你坐多久无关,关键是你中间没有出来活动,而持续久坐” Vernikos如是说。在对于人一天24小时躺在床上的研究中发现,每半个小时起立一次就能够阻止因长时间保持一个姿势而产生对身体不利的影响。换个姿势减轻负重(每个小时一次),增加充血量,能够避免小腿因久坐带来的灼热感和抽筋。
Your nerves are spazzing out
让你的神经失调
Sitting might be relaxing for your body, but to your nerves, it's torture. The unnatural position causes strained and pinched nerves, which results in pain throughout the body. "If you sit in one position long enough and you don't move, the muscle contracts. As it contracts, it pulls the nerves it's in contact with, so you go into a sort of spasm," said Vernikos. But since those nerves are pulled with every movement, shouldn't we feel pain all the time? Not exactly, said Vernikos. "It's one thing to stimulate the muscle to contract and relax when you're engaging in activity, but if you contract it and don't move for a long time, it can pinch the nerves and cause pain in the lower back and shoulders."
坐着对你的身体来说是一种放松,但对你的神经来说,那是一种折磨。别扭的姿势让你的神经拉伸挤压,导致周身疼痛。“如果你长时间保持一个姿势不动,你的肌肉就会萎缩,当它萎缩的时候,就会拉伸与它相关的神经,让你抽搐” Vernikos说。但是我们每做一个动作的时候,不是都会拉扯神经的么,难道我们不是应该一直都会感觉到酸痛么?事实并非如此。当你投身于某项活动的时候, 你的肌肉会拉伸并放松。但是你收缩肌肉并且长时间不动,肌肉就会拉扯神经,导致后背近腰处,和肩膀的疼痛。
