Mr. Prim: 我认为抓挠伤口是非常不得体的行为。虽然我知道皮肤在愈合时会非常痒,但这并不是抓挠的理由。事实上,伤口发痒与愈合过程本身有关。我们应该尽量避免抓挠伤口,保持伤口的清洁和卫生,以促进伤口的愈合。同时,我也强调了在日常生活中保持良好礼仪的重要性,例如正确的抓挠方式和用餐礼仪。 Emma Gersten-Zang: 作为一名儿科医生,我来解释一下为什么皮肤在愈合时会发痒。当你受伤时,身体会启动一系列的修复过程。首先,血细胞会聚集形成血块,然后干燥形成结痂,保护伤口免受细菌感染。同时,一些细胞会清理受损的细胞,新的细胞开始构建皮肤和胶原蛋白。在这个构建过程中,会释放出一些分子,这些分子会刺激神经末梢,产生痒的感觉。因此,伤口发痒是愈合过程中的正常现象,但我们应该尽量避免抓挠,以免引起感染或延缓愈合。
