While you obviously can't avoid an element that covers 70% of the planet and falls from the sky, people with aquagenic urticaria have to take some serious precautions when carrying out basic everyday tasks.

虽然您显然无法避免一种覆盖地 70% 天而降的元素，但患有水源荨麻疹的人在执行基本的日常任务时必须采取一些严肃的预防措施。

In solar urticaria, that same process seems to happen, but the molecule that’s causing the immune system freakout is a mystery.

在日光荨麻疹中，同样的过程似乎也会发生，但引发免疫系统异常反应的分子仍然是个谜。

Instead of showing up almost immediately, like solar urticaria, it can take hours or even days and it sticks around for a while, too.

与日光荨麻疹几乎立不同，它可能需要几小时甚至几天的时间才会， 且还会持续一段时间。

Unfortunately, this is reality for people with an extremely rare allergy to water called aquagenic urticaria.

不幸的是，对于水源荨麻疹这种极为罕见的水过敏症患者来说，这是实。

If you have a condition called solar urticaria, big, itchy welts develop within minutes of sun exposure.

如果你患有日光荨麻疹，皮肤会在晒太阳几分钟后大面积的瘙痒肿块。
