研究反义词是什么:揭开背痛最常见的七大误区

误区一：时时端坐预防背痛(1/7)#endSelect { width:450px; height:300px;}#rePlayBut{ background:url(/images/e_m_01.png) no-repeat 0px -1096px; width:122px; height:27px;}#nextPicsBut{ background:url(/images/e_m_01.png) no-repeat -135px -1096px; width:122px; height:27px; margin-left:13px;}#weiboShareBut{ background:url(/images/e_m_01.png) no-repeat -270px -1096px; width:122px; height:27px;float: left;margin-left: 13px;}.rdtj { text-align:left; font-family:"微软雅黑","黑体"; font-size:14px; text-indent:5px; font-weight:normal;}.picLink { float:left; width:122px; padding-right:13px;}.picTitle{ display:block; width:120px; line-height:14px; text-align:left;}a.picTitle { color:#fff;}a.picTitle:hover { color:#fff;}a.picTitle:visited { color:#fff;}.picImg {width:120px; height:100px;display:block;}.picImg a img {max-width:120px;max-height:90px;}.picLink img { padding-bottom:15px;}.btnBlk { margin-top:20px;}.btnBlk a{ float:left; width:180px; height:42px; }.btnBlk .picHome{ background:url(/images/news_home_focusOff.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_home_focusOff.png');_background:none;}.btnBlk .focusMe{ background:url(/images/news_follow_focusOff.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_follow_focusOff.png'); _background:none; float:left; margin-left:40px}a.picHome:hover{ background:url(/images/news_home_focusOn.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_home_focusOn.png'); _background:none;}a.focusMe:hover{ background:url(/images/news_follow_focusOn.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_follow_focusOn.png'); _background:none;}.add_yet { background:url(/images/news_followed.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_followed.png'); _background:none; width:186px; height:42px; float:left; text-indent:-999em; margin-left:19px;}#endSelect .E_Cont p { padding:8px 0px 0px 0px;} #sharetotblog {background:url(http://i2.sinaimg.cn/IT/deco/2009/0930/images/wbicon_cl_002.png) no-repeat;width:25px;height:23px;display:inline-block; margin:0;} 坐得太直，且长时间坐姿保持不变同样会给背部带来压力。如果你每天坐着的时间很长，那么每天试几次下面的方法：脚着地，背靠椅子，背部微屈。更好的方法是：每天站一会。 误区二：搬运重物会损伤背部#endSelect { width:450px; height:300px;}#rePlayBut{ background:url(/images/e_m_01.png) no-repeat 0px -1096px; width:122px; height:27px;}#nextPicsBut{ background:url(/images/e_m_01.png) no-repeat -135px -1096px; width:122px; height:27px; margin-left:13px;}#weiboShareBut{ background:url(/images/e_m_01.png) no-repeat -270px -1096px; width:122px; height:27px;float: left;margin-left: 13px;}.rdtj { text-align:left; font-family:"微软雅黑","黑体"; font-size:14px; text-indent:5px; font-weight:normal;}.picLink { float:left; width:122px; padding-right:13px;}.picTitle{ display:block; width:120px; line-height:14px; text-align:left;}a.picTitle { color:#fff;}a.picTitle:hover { color:#fff;}a.picTitle:visited { color:#fff;}.picImg {width:120px; height:100px;display:block;}.picImg a img {max-width:120px;max-height:90px;}.picLink img { padding-bottom:15px;}.btnBlk { margin-top:20px;}.btnBlk a{ float:left; width:180px; height:42px; }.btnBlk .picHome{ background:url(/images/news_home_focusOff.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_home_focusOff.png');_background:none;}.btnBlk .focusMe{ background:url(/images/news_follow_focusOff.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_follow_focusOff.png'); _background:none; float:left; margin-left:40px}a.picHome:hover{ background:url(/images/news_home_focusOn.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_home_focusOn.png'); _background:none;}a.focusMe:hover{ background:url(/images/news_follow_focusOn.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_follow_focusOn.png'); _background:none;}.add_yet { background:url(/images/news_followed.png) no-repeat; text-indent:-999em;_filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true,sizingMethod=crop, src='/images/news_followed.png'); _background:none; width:186px; height:42px; float:left; text-indent:-999em; margin-left:19px;}#endSelect .E_Cont p { padding:8px 0px 0px 0px;}

问题的关键不在于搬的东西有多重，而在于如何搬。当你要搬运重物时，你应该在它边上蹲下来，背部挺直，头抬起。然后站起来，用双腿的力量搬起重物。 误区三：躺在床上直到背痛消失休息的确有助于缓解引起背痛的急性损伤或肌肉劳损。但卧床休养的观点却是一个错误认识。在床上躺个一两天可能会加剧你的背痛。 误区四：背痛都由损伤所致椎间盘退变、外伤、疾病、感染甚至遗传因素都会导致背痛。 误区五：极瘦的人不会出现背痛任何人都有可能出现背痛。事实上，那些太瘦的人，例如那些患有厌食症（饮食失调）的人们，可能会出现骨质疏松，进而导致骨折或椎骨碎裂。 误区六：锻炼会使背痛加剧有规律地锻炼有助于预防背痛。对于因急性扭伤而导致背痛的人，锻炼可缓解背痛，医生可能会推荐一套锻炼方案，开始是轻微的运动，然后逐渐增大运动强度。 误区七：床垫越硬对背越有益与睡硬床垫（2.3，从硬到软以10计）的人相比，睡中等硬度床垫（5.6）的人更少出现背痛和无力。不过，根据睡眠习惯的差异及背痛病因的不同，不同的人可能需要不同的床垫。
