阴道的自然酸度略低于中性,通常在3.8至4.5之间。这意味着与其他类型的酸相比,它具有高浓度的氢离子。乍一看,这似乎是有害的,但实际上这对妇女的健康起到了重要作用。阴道酸性环境为细菌和真菌创造了不利的环境,这些细菌和真菌可引起酵母感染和细菌阴道病。事实上,得克萨斯农工大学的研究人员的一项研究发现,阴道液中含有杀死坏细菌和好细菌的物质,有助于保持支持阴道健康的微生物的平衡。要了解它是如何工作的,你需要看看背后的科学。酸度使用对数标度(称为pH标度)进行测量,其中1表示非常碱性的溶液和14个极酸性的溶液。纯净水的pH值为7,而高于或低于纯净水的任何物质分别为碱性或酸性。当谈到人体时,大多数细胞的pH值范围为6.8至7.4,但是各个区域都有自己的范围。例如,唾液的pH值约为6.8,而尿液通常约为5。然而,当涉及到阴道时,pH值低有助于防止有害细菌和真菌过度生长。
