日光敏感自然疗法

任何人如果暴露在太阳光下太久,都会被其中的紫外线晒伤。但是,有些人尤其容易被晒伤,或者皮肤对阳光反应过度。医学上把这种现象称为对日光敏感 (photosensitivity)。有些人在服用或涂摸某些药物或者自然物后会出现对日光敏感。一些疾病,如某些类型的卟啉病 (一组代谢紊乱性疾病) 或者狼疮等也会增加皮肤对日光的敏感性。另外还有一种情况,称为多形性日光疹 (PLEs),患有此病的人即使在相对不太强烈的日光照射下也会出现明显的皮疹。

日光敏感

对付日光敏感最有效的方法就是明确它是否是由外源性物质引起。如果是,就避免或者消除它。比如,抗生素是引起日光敏感最常见的药物之一。很多其他天然物质同样会引起类似的反应。另外一个常用的对付方法就是在晒太阳时涂摸防晒霜、穿防护服,甚至不照阳光。

日光敏感

可能有效的自然疗法有:

  • β-胡萝卜素 (Beta-carotene):它是一种富含于胡萝卜、甘薯等植物中的色素物质,至少对 PLEs 以及某些类型的卟啉病引起的日光敏感有作用。根据某个理论,日光照射会导致皮肤生成有害的化学物质 “自由基”,而β-胡萝卜素能中和这些有害的自由基,从而预防皮肤的损害。
  • 胡萝卜素

  • 其他推荐的天然疗法:很多研究 (但不是全部) 提示多种抗氧化剂如巧克力、维生素C、番茄红素、混合类胡萝卜素、富含黄酮醇的绿茶提取物、维生素E及玉米黄素等,口服或者外用均有助于预防皮肤晒伤。
