正文 第39章 讲卫生,再次科普(第3页/共4页)

吸取我们身上的血。比如你们经常头痒,就说明你们的头上长着一个叫虱子的生物,这个生物我们用肉眼可以看到,你们平时没事时在互相捉虱子玩。难道你们没有想过怎么防止头上长虱子吗?”

“原来如此,那么怎么防止我们的头上长虱子?”

众人开始议论起来。

“还有第二个原因,我说了大家可能就更无法理解,也很复杂,那我简单说一下。你们身上痒,还有一种可能就是得了荨麻疹.皮肤瘙痒症,或者过敏性皮炎。”

所有的原始人就开始蒙了,根本听不懂,一个个看着王伟,眼睛里冒着星星。

“荨麻疹是皮肤上出现很多形状不一的丘疹。丘疹出现后,会有明显的瘙痒,同时在出现两天时间内大部分会消失,但旧疹子消失了,新的又继续长出来。”

梅和明作为曾经的巫,他们都知道这种病,原来是叫荨麻疹。

而得过这种病的原始人都有深切的体会,那真是又痒又难受。

王伟又说道:

“皮肤瘙痒症是皮肤瘙痒而无皮损的皮肤疾病,可能和皮肤干燥、季节环境改变、异物刺激等有关。过敏性皮炎是指皮肤在接触到过敏原后所引起的变态反应,例如花粉、螃蟹、鱼虾等,不仅会引起身上总是痒,还伴有红疹、红肿等症状。”

众人完全听得一脑袋的浆糊,反应不过来。

“我说这么多,就是要大家平时要注意,讲卫生,爱整洁。大家吃食物时,也要注意食物的安全。最好不要生吃不熟的,还有被污染过的食物也不能吃。不熟的食物好理解,被污染过的食物,你们有吃过吗?比如那些腐败的食物,被其他动物啃食过的食物,这些都是被污染过的。”

夏大嘴举手后说:“所以大王经常让我们喝开水,也是这个原因。”

王伟点点头,他想到就为了给他们讲关于卫生的问题,已经耗费这么多时间。以后还有其他问题,那不是更花时间?得想个办法了。

众人知道了他们的大王良苦用心。

王伟悄悄对梅说了几句,梅带着花到厨房去了。

原始人对照王伟说的话,回忆以前得的有些病而出现的情况,一下子明白了,原来是这样呀。

他们对大王更加崇拜,如果说有人以前对大王是天神的想法还有一丝怀疑,那么现在完全打消了。

如果他们的大王不是天神,那么谁能说出困扰他们长久遇到的问题呢?
