科学已经证明经常接吻可以稳定人体心脏血管活动，可以防止高血压，可以降低胆固醇，可以全面提高人体的健康水平。以下是关于接吻的医学统计数据。

    护齿

    接吻胜过任何品牌的口香糖，因为它可以防止牙斑和龋齿，可以象牙膏一样防止龋齿的产生。中间的科学道理是这样的，接吻时可以人的口腔内分泌大量的唾液，而唾液中含有大量的钙和磷，能够保护牙齿免遭蛀噬，同时也减少了齿龈炎的发病机率。另外，接吻时人的唾液变成中性，可以起到预防许多牙科疾病的作用。

    美容

    与恋人激吻可以美容。一次激吻需要调动人的30块面部肌肉，从而使人的面部肌肤变得加平滑，使人的血液流通加快，接吻后擦摸护肤霜并使用面膜的效果最佳。

    减肥

    人们完全不必为了得到异性的青睐而去拼命节食减肥，虽然我们每一次激吻消耗的热量不过12卡路里，但是科学家已经声称，只要每天接吻3次，不次不少于20秒钟，你就可以减掉整整一磅赘肉。

    止痛

    我们常说的因多啡(endorphin)荷尔蒙实际上是麻醉剂。接吻越是激情四射，唾液内分泌的因多啡就越多，一次激吻可以产生和一片止痛药相当剂量的此类荷尔蒙。此外，接吻还可以制造抗生素。接吻时，天然的抗生素在人的唾液内分泌，它们也有麻醉的功效，所以以后当你疼痛难忍的时候，不要再吃什么止痛药了，记住这剂量药-那就是吻、吻、吻、吻够。

    抗压

    接吻可以防止压力荷尔蒙肾上腺皮质激素的形成，这种激素是造成高血压、高胆固醇、肌肉弱化和失眠的罪魁祸首。通常接吻可以有效的放松人的神经系统，使人摆脱压力。这就是为什么那些喜欢接吻的人都是乐天派的原因。每天接吻至少3次，可以使你24小时内保持浪漫愉快的心情。

    免疫

    我们的唾液当中有大量细菌，对所有人来说，这些细菌80%是一样的，另有20%是每个个体所独有的。当两个人接吻时，他们的唾液混合会产生各种微生物反应，这刺激人的免疫系统生产某种抗体，科学家称这是一种交叉免疫治疗。

    遗传兼容分析

    这绝不是夸张之辞！当你接吻时，你的大脑会立即对你情侣的唾液进行化学分析，并对你们的遗传兼容性作出“判决”。所以最好在初吻时就建立起你们的遗传兼容。

    总之，接吻对人体机能有着诸多益处。经常接吻的人用不着担心胃、膀胱和血液感染，而且你猜接吻还有什么作用--可以治打嗝。

When two people kiss, the mix of their saliva will response to a variety of micro-organisms, which will stimulate the human immune system to produce certain antibodies, scientists said this is a cross-immunotherapy.

    The analysis of  genetic compatibility
