9、损害大脑的发育，导致孩子成长过程中的不良行为。南非开普敦大学的尼尔斯 伯格曼医生说，为了让孩子的成长最优化，健康的新生儿在头几周应该睡在妈妈的胸口。此后，一直到三岁甚至四岁，他们都应该和妈妈同床睡。然而，有研究认为宝宝和妈妈同床睡会增加婴儿猝死风险，担心妈妈翻身会压到宝宝，让宝宝窒息，因此一般建议女性不要和宝宝同床睡。近日英国一项针对婴儿猝死的研究指出，近三分之二的不明猝死事件都是在和母亲同床睡时发生的。不过伯格曼医生说：“宝宝窒息和猝死不是因为妈妈在身边，而是因为其他因素：比如有毒气体、香烟、酒精、大枕头和危险的玩具等等。”该研究观察了 16 名婴儿在母亲胸口睡觉和在母亲床边的婴儿床睡觉的情
10、况。监测记录显示，婴儿在单独睡时心脏承受的压力是和母亲同床睡的三倍。在婴儿床中睡觉还会扰乱婴儿的睡眠，这样婴儿的大脑就比较无法适应“周期”，不能在动态睡眠和静态睡眠两种模式中切换。在婴儿床中，16 名婴儿中只有 6 名可以有静态睡眠，而且睡眠质量也相对差得多。在动态和静态睡眠之间切换被认为对大脑正常发育很关键。动物研究曾将压力大和睡眠不足并存的状况与青少年时期的行为问题联系在一起。伯格曼医生说，压力荷尔蒙引起的大脑的变化可能会让孩子日后更难建立感情关系，并可能导致性乱交这样的问题。Vocabulary:paediatrician: 小儿科医生cot: 婴儿床optimal: 最优的，最佳的cot death: 婴儿猝死promiscuity: 性乱交
