女人为何要戴胸罩？
最新网址：m.ltxsdz.com
这个问题仿佛一直被讨论着，很多人视脱去胸罩就像脱去加诸在美眉们身上的枷锁，这代表女性意识的抬头。龙腾小说ltxs520.com几十年过去了！虽然中国的美眉们不用再裹起小脚了，但是，胸罩却没有让女人遗弃在博物馆里，反而是增加了更多的功能性与外观的选择性呢！也因此更加让许多爱美的美眉们不能没有“它”哩！
其实，如果你不想让咪咪愈来愈长的话，就乖乖戴起胸罩吧！就生理健康而言，人类是直立行走的动物，而咪咪的内容物是脂肪与乳房组织，并且没有任何骨骼架构，若再没有外力的包覆与支撑，乳房是很容易来回摆动的啦（如果再加上地心引力），这样可是很容易变型的，而且，咪咪丰满的美眉，更容易因为不穿戴胸罩而变型的唷！如果不想让自己的咪咪变型的美眉们，可要穿起胸罩才能保持美丽的胸型。
除了外型之外，没有胸罩支撑的咪咪也可能产生胸部韧带肌肉拉伤或乳管因来回牵拉而造成血液循环障碍引发血肿、组织坏死等问题，爱美的美眉们，怕了吧？赶快去挑件适合自己的胸罩吧。
乳房与乳罩护养的学问
女性乳房是两个半球形，它有两种作用，一是分泌乳汁以哺育婴儿；二是性征器官，对性刺激很敏感，并对性刺激产生一系列反应。乳房的中央是乳头，乳头周围的颜色较深的区域叫做乳晕。乳房下面是胸部肌肉，如果胸肌发达，可以将乳房托起，显得更为健美。
乳房内有腺泡，这好像是葡萄样的一串串小球。乳头富有神经末梢，感觉很灵敏，可以勃起。乳房内有提拉乳房的韧带，能使乳房保持一定的形状。
戴乳罩不仅仅是为了体态健美，它还可以支持和托扶乳房，使乳房的血液循环通畅，防止乳腺血流阻滞，有利于乳房发育和增强抗能力。哺乳期戴胸罩，一可防止乳房下垂，二还可以保持乳头清洁，预防乳腺炎的发生。
戴胸罩也要有个讲究，才能达到保健目的。首先，胸罩的型号要与乳房大小相适应，不能太紧，尤其是少女发育期，随着乳房的发育，要及时更换适合的型号。其次，制作胸罩的材料，不要太硬，要柔软、有承托力和一定的透气性能，以薄棉布和的确凉为好。
胸罩的背带不能太细太窄，应有二个手指宽度，不能用细绳代替，以免损伤皮肤。第三，每天要有一定的调节时间，夜间就寝时应把胸罩取下，使乳房和胸、背部肌肉放松，有利于局部血液循环。
